SPECIFIC TARGET ORGAN TOXICITY - single exposure ： This product is classified in Category 1.
(Sulfuric Acid)： Low-dose inhalation exposure to humans causes airway irritation symptoms
such as cough and shortness of breath (DFGOT, 2001), while high-dose
exposure causes acute effects such as coughing, shortness of breath and clot
discharge as well as decreased lung function. There is a description thatpersistent effects such as fibrosis and emphysema were observed and thatbleeding and dysfunction of the lungs were observed after inhalation exposure
to guinea pigs for 8 hours (ATSDR, 1998).
(Potassium hydroxide)： The substance has been described as acting as a strong alkali on the s
kin and mucous membranes, and inhalation exposure to dust or mist ma
y cause irritation and tissue damage in the upper respiratory tract, possi
bly resulting in septal injury and pulmonary edema (ACGIH (7th, 2001),
SIDS (2004), PATTY (6th, 2012), Proposed reason book for Sanitary Soc
iety allowable concentration (1978)).
(Silver Nitrate)： The substance is corrosive and airway irritant (ATSDR(1990), PATTY(6th,2012)). In humans, exposure to dust inhalation causes irritation of airway
mucus, acute oral poisoning symptoms such as burning sensation or pai
n in the mouth, salivation, vomiting, abdominal pain, diarrhea, severe gas
troenteritis, decreased blood pressure, decreased respiratory rate, dizzine
ss, Convulsions, diaphragmatic myopathy, coma, central nervous systemdisorders, death have been reported (HSDB(Access on September 2014)).
There is no data for experimental animals.
(Silica gel)
： Irritating to respiratory tract (SIDS (2006), ECETOC JACC (2006))
SPECIFIC TARGET ORGAN TOXICITY - repeated exposure ： This product is classified in Category 1.
(Sulfuric Acid)： The 28-day inhalation exposure test in SIDS (2001) rats shows cell proliferation in thelaryngeal mucosa within the guidance value range of Category 1, and the ATSDR(1998) guinea pig 14-139-day repeated inhalation exposure test in Category 1
Concentrations within the guidance range of nasal septal edema, pulmonary
emphysema, atelectasis, bronchial congestion, edema, hemorrhage, thrombosis, andother airway and lung disorders are further assessed in the 78-week inhalation
exposure study in cynomolgus monkeys. It has been reported that histologicalchanges such as hyperplasia of cells and thickening of wall in bronchi were observedat doses within the guidance value of Category 1 (0.048 mg / L, 23.5 Hr / Day).
(Potassium hydroxide)： For humans, it is noted that the injury caused by inhalation of dust and mist of thissubstance is mainly inflammation of the upper respiratory tract, and chronic action
causes ulcers in the nasal septum. However, there are no reports of surveys andresearches on airborne concentrations and the occurrence of disorders (Proposal
Reasons for Sanitation Society Allowed Concentrations(1978)). Exposure to dust or
mist may cause irritation of the eyes and respiratory tract, lesions of the nasal septum(ACGIH(7th, 2001)). As mentioned above, although there is not enough information,
it is obvious that this substance is an alkaline substance and causes respiratory
inflammation by inhalation.
(Silver Nitrate)： Twenty-five out of 30 workers exposed to silver dust for less than 1 year to over 10
years at the silver nitrate and silver oxide manufacturing plants have upper respiratory
tract irritation symptoms (sneezing, runny nose, stuffy nose, sore throat pain) There
are descriptions that 10 persons complained of abdominal pain (severe pain andreduced by antacid) (ATSDR(1990), ACGIH(7th, 2001)). Among them, abdominal
pain may be due to the effect of mucous membrane irritation that orally ingested apart of dust, and it is a symptom of a few cases (one third of the whole), anddescription of other digestive symptoms such as diarrhea and vomiting It was thoughtthat it should not be targeted for the target organ. On the other hand, in theexperimental animals, rats were administered a drinking dose of 222 mg Ag / kg / day(equivalent to 349.6 mg / kg / day) to rats for 37 weeks, and increased mortality wasobserved after 23 weeks. There is no description of organ toxicity other than silverosis(ACGIH(7th,2001)). In addition, in a study in which 89 mg Ag / kg / day (equivalent to
140 mg / kg / day) was administered to rats for nine months. Although it has been
described that ventricular hypertrophy was observed (ATSDR(1990),
ACGIH(7th,2001)), cardiovascular effects have not been reported in human and otheranimal studies, and the results are reliable. It is said that there is no (ATSDR(1990)).
Besides this, there is no data available for classification in experimental animals.
