The Aim. the forensic determination of the severity of closed chest injuries with intact ribs in victims hospitalized in a specialized surgical hospital to establish diagnostic expert criteria for expert assessment of such dmages.Materials and methods. 52 case histories of patients hospitalized hospitalized at the Kharkiv institute of general and emergency surgery named after V.T. Zaitseva were analyzed. Patients were divided into 4 groups based on the dynamics of morpho-functional pathological changes of the injured organs, the final results of the injury, and the presence of life-threatening phenomena.Results. The analysis of observations showed that the main traumatic factor in the emergence of the studied cases is the impact mechanism of blunt solid objects on the chest. Patients with closed blunt chest trauma were divided into observation groups depending on the morphology of the injuries received. The following main variants of the received injury are distinguished: without a contusion and bruised chest and the presence of intrapleural injuries and complications, a chest contusion without complications. Severe injuries were estimated in 15.4% of cases of acute respiratory failure and cases of trauma of partial or complete lung loss. Injuries of medium severity were established in 26.9% of cases of trauma in the absence of danger to life. Minor injuries were established in 57.7% of cases of trauma in the presence of intrapleural injuries and complications or minor injuries without any complications.Conclusions. When forensically determining the degree of severity of closed injuries of the chest, it is necessary to evaluate the morphology of the injury and clinic functional manifestations of life-threatening phenomena. At the same time, diagnostic signs which must be used when determining the severity of physical injuries are the following: the presence of clinical and functional signs of acute respiratory failure, loss of part or all of the respiratory organ (lungs), dynamics and duration of recovery of post-traumatic morpho-functional changes injured organs.

Published: February 2023

The footings laid in close proximity imposes a definite change in the behaviour of the adjacent footing, subsequently changing the behaviour of the nearby footings. The present study emphasises the behaviour of the nearby strip footings embedded at a different level by adopting the commercially available finite element analysis program, ABAQUS. The load-settlement behaviour, ultimate bearing capacity (UBC), and the failure patterns of adjacent strip footings are assessed by considering the Mohr-Coulomb failure criterion. The UBC is of the nearby footings (left and right) are estimated and represented in terms of interference factors (ξL/ξR
) defined as the UBC of a footing in the presence of adjacent footing to that of same considered for equivalent isolated footing. The results reveal that a significant influence of the adjacent footing is experienced when the spacing between the footings (S/B) is lesser, and they behave as the single footing of greater width at S/B = 0.25 irrespective of the level of embedment depth. Furthermore, the influence of interference increases with the increase in the embedment depth of adjacent footing. It is found that the ξL
is significantly more for a lower level of embedment depth, and the same increases with an increase in the embedment depth of the right footing but on the contrary ξR
decreases. The increase in the peak interference factor, ξL-max
for DL/B = 0.5 is 2.1% and 4.2% when DR/B = 0.75 and DR/B = 1.0, respectively.

Published: February 2023

Due to the high risk of exposure to various contaminants in drinking water, pitcher filtration is rapidly growing in popularity worldwide as a cheap and easy method to remove pollutants from drinking water. On the other hand, an evaluation of the real-time performance of pitchers is not possible for usual consumers. This study presents the performance of pitcher filtration in the removal of copper, chlorine, and chloroform from tap drinking water. Pitchers were packed with Aquaphor cartridges JS500, A5, and B25. Experiments were performed with model solutions, which were prepared from hard drinking water (7.5 mval/L, pH=7) spiked with copper, hypochlorite sodium, and chloroform. It was found that pitcher filtration is a very effective method for the removal of pollutants such as heavy metals, chlorine, and disinfectants byproducts. The concentration of copper, chlorine, and chloroform in filtrates did not exceed the maximum admissible values. Cartridges JS500, A5, and B25 reduced chlorine at a comparable level – almost 100%. During the whole experimental period, removal of chloroform was slightly better for JS500 (100%) and A5 (100%) cartridges than for B25 (91.4–97.7%).

OSOBITOSTI NASLJEDNO-PRAVNOG UREĐENJA CRESKO-OSORSKOG STATUTA IZ 1441. GODINE
Authors: Kasap Jelena
Published: February 2023

Particular attention in this research is paid to the regulation of property relations arising after the death of the testator in the Statute of Cres-Osor. The provisions regulating inheritance relations among family members in the content of this source confirm the importance of the family as a community as well as the importance of family property within this late mediaeval commune. In this regard, the Statute of Cres-Osor shows specific features. The equality of male and female descendants when it comes to intestate inheritance is marked by the inheritance regulation of the rare communes of the Kvarner region, including the Cres commune. In this regard, it is important to determine the position of women in marriage and family. In a period when under the influence of the reception of different legal sources, primarily of the Venetian and Byzantine ones, most Adriatic communes adopted almost identical features of inheritance law, in which the inheritance of family property is linked to a certain degree of kinship. The Statute regulated testamentary freedom and free disposal of property according to the will of the testator or for religious purposes. As the systematic analysis of the legal provisions of the statute is merely the subject of the discussions in academic community, a detailed analysis of hereditary relationships regulated by the provisions of this source will certainly contribute to understanding of the legal reality of this mediaeval island commune. This research conducts a detailed analysis into the legal source, and compares specific provisions of other close communes in order to analyse inheritance by will and intestate inheritance regulation as well as other important issues such as the position of certain categories of heirs. Moreover, it aims at detecting the origin of a separate regulation of hereditary relations in this island community.
Cephalohematomas, an occult nidus for infection and inflammation: A case report and review of the literature
Authors: Li Daphne , Tsiang John Ta-Hsiang , Mackey Kimberly A. , Bonwit Andrew , Pappu Suguna
Published: February 2023

Background:

Cephalohematomas (CH) are benign neonatal fluid collections that arise between the periosteum and skull due to birth trauma, and usually resolve spontaneously without intervention. CH may rarely become infected.

Case Description:

The authors report a case of sterile CH requiring surgical evacuation in a persistently febrile neonate treated with intravenous (IV) antibiotics for Escherichia coli urosepsis. Diagnostic tap of the CH yielded no pathogens, but given the persistence of fevers, surgical evacuation was performed. The patient demonstrated clinical improvement postoperatively.

Conclusion:

A systematic review of literature was conducted through a MEDLINE search using the keyword “cephalohematoma.” Articles were screened for cases of infected CH and their subsequent management. Clinicopathological characteristics and outcomes of the present case were reviewed and compared to those in the literature. Infected CH were reported in 25 articles describing 58 patients. Common pathogens included E. coli and Staphylococcal species. Treatment included a course of IV antibiotics (10 days–6 weeks) and often included percutaneous aspiration (n = 47) for diagnostic and therapeutic purposes. Surgical evacuation was performed in 23 cases. To the authors’ knowledge, the present case is the first documented report in which evacuation of a culture-negative CH resulted in resolution of the patient’s clinical symptoms of sepsis that persisted despite appropriate antibiotic treatment. This suggests that patients with CH should be evaluated through diagnostic tap of the collection if there are signs of local or persistent systemic infection. Surgical evacuation may be indicated if percutaneous aspiration does not result in clinical improvement.
A persistent trigeminal artery demonstrates cerebrovascular embryologic development
Authors: Bram Richard , Choi Jason L. , See Alfred P. , Atwal Gursant S.
Published: February 2023

Background:

Cerebrovascular embryologic development is characterized by the presence of four well-described carotid-vertebrobasilar (VB) anastomoses. As the fetal hindbrain matures and the VB system develops, these connections involute, yet some may persist into adulthood. The persistent primitive trigeminal artery (PPTA) is the most common of these anastomoses. In this report, we describe a unique variant of the PPTA and a four-way division of the VB circulation.

Case Description:

A female in her 70s presented with a Fisher Grade 4 subarachnoid hemorrhage. Catheter angiography revealed a fetal origin of the left posterior cerebral artery (PCA) giving rise to a left P2 aneurysm which was coiled. A PPTA arose from the left internal carotid artery and supplied the distal basilar artery (BA) including the superior cerebellar arteries bilaterally and the right but not left PCA. The mid-BA was atretic and the anterior inferior cerebellar artery-posterior inferior cerebellar artery complexes were fed solely from the right vertebral artery.

Conclusion:

Our patient’s cerebrovascular anatomy represents a unique variant of the PPTA not well described in the literature. This demonstrates how hemodynamic capture of the distal VB territory by a PPTA is sufficient to prevent fusion of the BA.

The goal of the paper was to show that the phenomena observed in the works of L. Montagnier, the Nobel laureate on physiology, 2008, with the behavior of some bacteria and viruses (including the Human Imunodeficiency Virus), may be related to the effect of microwave fluxes primarily of ionospheric origin, to formation of water-containing complexes. A well-known mechanism of associative formation is taken into account, taking into account the high affinity for the proton in water molecules. The approach developed in our recent papers is used within the framework of supramolecular physics of complex molecular structures. Supramolecular physics describes a processes developing outside the molecules (atomic-molecular cores) in whose evolution to the complex forms (clusters, associates) electromagnetic radiation of external origin absorbed by exited Rydberg components of molecular complex takes part. Due to increasing value of orbital momentum of Rydberg electrons the stability of the complex grows because probability for forming a stable neutral cluster becomes higher as the electron more seldom penetrates into the ion core. We use the analogy with well known supramolecular chemistry proposed by J.-M. Lehn, the Nobel laureate on chemistry, 1987. He also discussed a possibility of contribution of cosmic influence both to information exchange in living organism and reaction to the environmental stimuli.

The Potential Environmental and Climate Impacts of Stratospheric Aerosol Injection: A Review
Authors: Huynh Han , McNeill V. Faye
Published: February 2023

Given the rise in global mean temperature as a direct consequence of increasing levels of greenhouse gases (GHG) in the atmosphere, a variety of climate engineering approaches, including stratospheric aerosol injection (SAI), have been proposed. Often criticized as a distraction from global efforts towards reducing GHG emissions, SAI aims to increase the Earth’s albedo by seeding aerosols in the lower stratosphere. SAI has been explored extensively in modeling studies based on observations of temporary cooling of the Earth’s surface following major volcanic eruptions which introduced significant loadings of sulfate particles into the stratosphere. The cooling effect is accompanied by other significant consequences including stratospheric heating, stratospheric ozone (O3) depletion, and reduced global mean precipitation. In order to understand the potential environmental and climate impacts of SAI, we review the state of the knowledge regarding these issues, starting from an aerosol science perspective. We summarize aerosol radiative properties and the role they play in defining the optimal chemical and physical aerosol characteristics for SAI, and their implications for lower stratospheric warming. We then review in depth the impacts of stratospheric aerosol heterogeneous chemistry on global O3 levels. We review SAI modeling studies as well as their uncertainties, in comparison to the observed environmental and climate impacts of volcanically derived sulfate aerosols, including impacts on global temperature, stratospheric warming, and hydrological cycle. We also discuss the current governance and economic considerations of the application of SAI and raise essential questions from both research and social standpoints that must be addressed before SAI is deployed for climate change mitigation.

Энтеральная среда выполняет важную роль в поддержании гомеостаза и во взаимодействии организма с внешней средой. Высокомолекулярные соединения, поступающие с пищей, не способные проникнуть через мембрану кишечника во внутреннюю среду организма, должны быть подвергнуты преобразованию до относительно простых молекул, и активное участие в этом процессе принимают ферменты пищеварительных желез. Изучали места локализации и активность ферментов гамма-глутамилтрансферазы и щелочной фосфотазы на уровне энтеральной среды у модельных животных (мини-пигов). Определена активность ферментов в слизистой оболочке, нативном химусе кишечника и его фракциях - плотной эндогенной и растворимой. Активность гамма-глутамилтрансферазы обнаруживается как в слизистой оболочке, так и в химусе всех отделов тонкого кишечника. Наиболее высокая активность гамма-глутамилтрансферазы зафиксирована в растворимой фракции химуса, самая низкая - в плотной эндогенной фракции с аналогичной выраженной динамикой активности по всей длине тонкого кишечника. Самая высокая активность щелочной фсфотазы обнаружена в слизистых наложениях тонкого отдела кишечника. В ходе эвакуации химуса активность фермента в нем снижается. Максимальная активность щелочной фосфотазы зафиксирована в плотной эндогенной фракции химуса тонкого отдела кишечника.

The enteral environment plays an important role in maintaining homeostasis as well as in the interaction between the living body and the external environment. High molecular weight compounds that enter with food, and unable to penetrate the intestinal membrane into the internal environment of the body, must be converted to relatively simple molecules. Enzymes of the digestive glands take an active part in this process. We studied the localization sites and the activity of the enzymes gamma-glutamyltransferase and alkaline phosphatase at the level of the enteral environment in model animals (mini-pigs). The activity of enzymes in the mucous membrane, native chyme of the intestine and its fractions, dense endogenous and soluble, were determined. The activity of gamma-glutamyl transferase is found both in the mucous membrane and in the chyme of all parts of the small intestine. The highest activity of gamma-glutamyltransferase was recorded in the soluble fraction of the chyme, the lowest in the dense endogenous fraction with a similar pronounced dynamics of activity along the entire length of the small intestine. The highest activity of alkaline phosphatase was found in mucous overlays of the small intestine. During the evacuation of the chyme, the activity of the enzyme in it decreases. The maximum activity of alkaline phosphatase was recorded in the dense endogenous fraction of the chyme of the small intestine.

Comparative analysis of the content of photosynthetic pigments in some types of moss species from urban zones of the city of Tver
Authors: Мейсурова Александра Федоровна , Суворова Алена Алексеевна , Бревдо Екатерина Юрьевна
Published: February 2023

Проведена сравнительная оценка содержания фотосинтетических пигментов у двух видов листостебельных мхов (Leskea polycarpa Hedw. и Lewinskya speciosa (Nees) F. Lara, Garilleti et Goffinet) в урбоэкосистемах города Твери с разным уровнем антропогенной трансформации. Эти виды имеют сходные значения основных показателей (концентрации хлорофиллов Хл a и Хл b, суммарное содержание Хл a и Хл b; соотношения концентраций хлорофиллов a/b). Амплитуды изменения этих величин концентраций пигментов сопряжены с разными уровнями загрязнения среды (Хл a) и микроклиматические условия произрастания видов (Хл b). Несмотря на сходные изменения в содержании пигментов, индикаторные возможности сравниваемых видов отличаются. С помощью Фурье-ИК спектрального анализа показано, что степень чувствительности к изменению химического состава воздуха у Lewinskya speciosa выше, чем у Leskea polycarpa. В ИК-спектрах образцов Lewinskya speciosa обнаружены изменения, связанные с накоплением алкилнитратов (R-O-NO2), которые указывают на наличие в воздухе NO2.

A comparative assessment of the content of photosynthetic pigments in two species of leaf mosses (Leskea polycarpa, Lewinskya speciosa) in the urban ecosystems of the city of Tver with different levels of anthropogenic transformation was carried out. These species have similar values of the main indicators (concentrations of chlorophylls Chl a and Chl b, total content of Chl a and Chl b; ratios of chlorophyll a/b concentrations). The amplitudes of change in these values of pigment concentrations are associated with different levels of environmental pollution (Chl a) and microclimatic conditions for the growth of species (Chl b). Despite similar changes in the content of pigments, the indicator capabilities of the compared species differ. Using FTIR spectroscopy, it was shown that the degree of sensitivity to changes in the chemical composition of air in Lewinskya speciosa is higher than in Leskea polycarpa. The IR spectra of Lewinskya speciosa samples showed changes associated with the accumulation of alkyl nitrates (R-O-NO2), which indicate the presence of NO2 in the air.

В работе представлены результаты анализа содержания тяжелых металлов (кадмия, кобальта, марганца, меди, мышьяка, никеля, свинца и цинка) в растениях в 14 объединенных растительных пробах, собранных в зоне разработки Малмыжского месторождения медно-порфировых руд в точках контроля на границе санитарно-защитной зоны, а также на аналоговых площадях в подобных контролируемых сообществах, но расположенных вне зоны воздействия. Концентрации исследованных элементов в растениях большинства пробных площадок находятся в пределах допустимых значений, что не вызывает нормального функционирования растений, в том числе и тяжелый металл высокой токсичности - кадмий. По результатам анализов в растениях на пробных площадках он находится в пределах допустимых концентраций. На девяти пробных площадках отмечено высокое содержание марганца, что связано с природными особенностями папоротников и брусники обыкновенной накапливать этот элемент в своих тканях. Такие высокие концентрации марганца в растениях являются наследство закрепленными

The paper presents the results of the analysis of the content of heavy metals (cadmium, cobalt, manganese, copper, arsenic, nickel, lead and zinc) in plants in 14 combined plant samples collected in the development zone of the Malmyzhskoe deposit of porphyry copper ores at control points at the border of the sanitary-protection zone, as well as in analogue areas in similar controlled communities outside the impact zone. The concentrations of the studied elements in the plants of most of the test plots are within the acceptable range, which does not cause the normal functioning of plants, including a heavy metal of high toxicity - cadmium. According to the results of analyzes in plants on trial sites, it is within the permissible concentrations. On nine test plots, a high content of manganese was noted, which is associated with the natural characteristics of ferns and common lingonberries to accumulate this element in their tissues. Such high concentrations of manganese in plants are heritable.
N.I. KAREEV ON THE MUTUAL INFLUENCE OF CULTURES IN LINE WITH THE HISTORIOSOPHY OF THE SLAVOPHILES
Authors: Соболева Надежда Александровна
Published: February 2023

Проанализированы воззрения Н.И. Кареева на проблему взаимовлияния культур сквозь призму философии славянофилов. На примере трех представителей славянофильства отмечена динамика идеи противопоставления российской и западной культур. Первая стадия - критика культурного заимствования, но без прямого дистанцирования от ценностей Запада (А.С. Хомяков); вторая - противопоставление исторических истоков обеих культур (К.С. Аксаков); третья - признание полного отчуждения России от Запада (В.И. Ламанский). Выявлено, что, по мнению Кареева, историко-культурный скептицизм славянофилов помог поставить вопрос о ценности любого типа культуры, не только в дихотомии «Россия - Европа», но и «Восток - Запад».

The views of N.I. Kareev on the problem of mutual influence of cultures through the prism of the philosophy of Slavophiles are analyzed. Using the example of three representatives of Slavophilism, the dynamics of the idea of contrasting Russian and Western culture is studied. The following stages of this process are revealed: the first stage is the criticism of cultural borrowing, but without direct distancing from the values of the West (A.S. Khomyakov); the second is the juxtaposition of the historical origins of both cultures (K.S. Aksakov); the third is the recognition of Russia's complete alienation from the West (V.I. Lamansky). It is revealed that, according to Kareev, the historical and cultural skepticism of the Slavophiles helped to raise the question of the value of any type of culture, not only in the dichotomy «Russia - Europe», but also «East - West».

Background Inadequate furcation repair often leads to tooth loss due to accompanying endodontic and periodontal problems. An appropriate material and technique can prevent this. This study aimed to evaluate the sealing ability of Mineral Trioxide Aggregate MTA Glass Ionomer Cement GIC and Biodentine as a furcation repair material with and without laser.Methods Ninety human extracted mandibular molars were decoronated 3 mm above and below the cementoenamel junction. After access opening sticky wax was placed over the canal orifices. A defect of 1 mm diameter was made the chamber and perforation were flushed with water and dried. Further the specimens were divided into six groups based on the furcation repair materials used n 15. Group 1 MTA with laser Group 2 MTA Group 3 GIC with laser Group 4 GIC Group 5 Biodentine with laser and Group 6 Biodentine. In groups 1 3 and 5 diode 810 laser irradiation was done for furcal defect before placing the materials. Specimens were subjected to 2 methylene blue for 48 hr washed sectioned mesiodistally and depth of dye penetration was examined under stereomicroscope. Statistical software SPSS version 22 was used for analysis. One way analysis of variance followed by Post hoc Tukey multiple comparison test was done p le0.05.Results Among the experimental materials less microleakage was observed with laser activation than without using laser. Biodentine with laser Group 5 showed less microleakage which was statistically significant compared to all the other groups except group 6 i.e Biodentine without laser.Conclusion Biodentine with laser activation was effective in furcation repair and in prevention of microleakage.nbsp

Aim The purpose of the study was to compare the changes in salivary pH and salivary flow rate after chewing xylitol-containing chewing gum in children at high risk and low risk for dental caries.Method Forty school children aged 9 to 12 years were selected for the study according to the inclusion criteria and were divided into two groups - Group A 20 children at high caries risk for dental caries and Group B 20 children at low risk for dental caries. Initially baseline saliva samples were collected for both the groups and subjected to salivary pH and flow rate assessment. Following this the children were instructed to chew xylitol-containing sugar-free chewing gum for 10 minutes. Salivary pH assessment was done at different time intervals like 0 15 30 45 and 60 minutes. The salivary flow rates were measured once the froth settled.Results Data was analyzed statistically using repeated-measures ANOVA. After chewing sugar-free gum salivary flow rate showed no significant difference pgt0.05 between Group A and Group B whereas salivary pH showed a statistically significant difference plt0.001 between the two groups at different time intervals.Conclusion Xylitol-containing sugar-free chewing gum showed an elevated salivary pH in children at high risk for dental caries when compared to the low-risk group while it showed an equal effect on salivary flow rate in both the groups. Xylitol-containing chewing gums were more effective in children at high risk for dental caries than the low-risk group.

Background Oral submucous fibrosis OSMF quid-induced lichenoid lesions QILL and leukoplakia show characteristic individual histological features. However all the three lesions are caused by quid chewing. There is a possibility that these lesions may occur together in the same patient. But sometimes there may be no clinical evidence of concomitant lesions with changes being seen at histopathological level.Aim To determine the presence of concurrent histopathological features in oral leukoplakia OSMF and QILL.Method A retrospective analysis of hematoxylin and eosin-stained slides of OSMF n 60 QILL n 20 and leukoplakia n 60 was done. Slides were analysed for the presence of lichenoid features in OSMF and leukoplakia. Fibrosis was searched for in lichenoid reaction and leukoplakia.Results Fifteen cases 25 of OSMF revealed histopathological features of lichenoid reaction. Eight 40 cases of QILL and two cases 3.3 of leukoplakia revealed the presence of fibrosis in the connective tissue. Ten cases 16.6 of leukoplakia revealed the presence of lichenoid reaction. Lichenoid features included subepithelial band of inflammatory cells basal cell degeneration and reduplication of basement membrane. All cases were associated with some form of betel quid chewing.Conclusion This study aimed to highlight the possibility of overlapping histopathological features of three different lesions despite the clinical presence of only one lesion. This may suggest the initiation of a second disease process. Since all the three lesions have a malignant potential these concurrent features may aid in prevention and adequate diagnosis.nbsp

Background Platelet Rich Fibrin PRF surgical biological substitute harnesses cells with growth factors and cytokines in platelets for enhanced regeneration and tissue repair. The innovation in the low-speed centrifugation concept is the Advanced-PRF. However the impact of type 2 diabetes mellitus on PRF has not been explored till date. Hence this study was carried out to compare growth factor levels in Leukocyte and Platelet Rich Fibrin L-PRF Advanced- Platelet Rich Fibrin A-PRF and A-PRF amongst diabetic individuals.Methods Venous blood was drawn for the analysis of HbA1c CBC platelet indices and PRF membrane preparation. A total of 90 PRF membranes L-PRF A-PRF and A-PRF from healthy well-controlled and poorly controlled diabetics were subjected to assessment of growth factor release of Vascular Endothelial Growth Factor VEGF Insulin Growth Factor IGF and Fibroblast Growth Factor FGF-21 at days 1 3 and 7. The independent t-test one-way ANOVA and Tukey post hoc test were used to statistically analyze the data.Results A significantly higher platelet index and growth factor VEGF IGF-1 FGF-21 release in diabetics from A-PRF in comparison with A-PRF and L-PRF at days 1 3 and 7 were seen. This was significantly higher in the poorly controlled diabetic group p lt0.05. These findings were found to be positively related to platelet indices and HbA1c levels.Conclusion A-PRF of diabetics demonstrated a higher growth factor release over a period of 7 days suggesting its usage as regenerative material.

Canned meat and chicken are common and popular protein sources around the world
because they constitute low-cost and affordable products. However, canned meat and
chicken might become sources of human exposure to chemical residues such as heavy
metals. This study aimed to estimate the residual contents of six heavy metals, namely
leads (Pb), cadmium (Cd), arsenic (As), mercury (Hg), aluminium (Al), and tin (Sn) in the
samples of canned beef, corned beef, and chicken luncheon. Likewise, estimated daily
intakes (EDI), potential health risks, hazard quotient (HQ), and hazard index (HI), of the
heavy metals associated with the consumption of such products among the Egyptian
population, were calculated. Comparing the obtained results with available maximum
permissible limits (MPL) of Egyptian and international standards revealed that
acceptability rate at 20%, 15%, and 35% in Pb; 40%, 25%, and 45% in Cd; 30%, 25%,
and 35% in As; 25%, 20%, and 35% in Hg; 15%, 10%, and 15% in Al of the canned beef,
corned beef, and chicken luncheon, respectively. Whereas all samples were accepted
according to the MPL of Sn. The calculated HQ and HI for the examined heavy metals
based on the daily intakes revealed values of canned beef and chicken luncheon <1.0
indicating the safety of consumer meanwhile, the value was 1.021 for canned corned beef
indicating potential human health risks. Therefore, it is advisable to reduce the daily
intake of canned corned beef.
