ÚDAJE
An OECD inter-laboratory comparison exercise, done in 1988, has shown that the methods give consistent results. However, depending on the physical characteristics of the substance to be tested, one or other of the methods may be preferred. I.2. SELECTION OF THE APPROPRIATE METHOD
Medzilaboratórny porovnávací test OECD, vykonaný v roku 1988, ukázal, že metódy poskytujú zhodné výsledky.
In order to select the most appropriate method, information on the chemical's solubility, vapour pressure and adsorption characteristics is essential. The chemical structure or formula should be known in order to calculate theoretical values and/or check measured values of parameters, e.g. ThOD, ThCO2, DOC, TOC, COD (see Appendices 1 and 2). Test chemicals which are soluble in water to at least 100 mg/l may be assessed by all methods, provided they are non-volatile and non-adsorbing. For those chemicals which are poorly soluble in water, volatile or adsorbing, suitable methods are indicated in Table 1.
V závislosti od fyzikálneho charakteru látky, ktorá má byť testovaná, sa však môže dávať prednosť určitej metóde.
The manner in which poorly water-soluble chemicals and volatile chemicals can be dealt with is described in Appendix 3. Moderately volatile chemicals may be tested by the DOC Die-Away method if there is sufficient gas space in the test vessels (which should be suitably stoppered). In this case, an abiotic control must be set up to allow for any physical loss.

Test procedure Test concentrations
Postup testu
Range finding test The range of concentrations just causing mortalities of 0 to 100 % may be determined in a range-finding test to provide information on the range of concentrations to be used in the definitive test.
Koncentrácie testovanej látky sú vyjadrené ako hmotnosť látky na hmotnosť sušiny základného substrátu (mg/kg).
The substance should be tested at the following concentrations: 1000; 100; 10; 1; 0,1 mg substance/kilogram test substrate (dry weight). If a full definitive test is to be carried out, one test batch per concentration and one for the untreated control, each with 10 worms, could be sufficient for the range-finding test. Definitive test
Test na vyhľadávanie rozsahu
The results of the range-finding test are used to choose at least five concentrations in a geometric series just spanning the range 0 to 100 % mortality and differing by a constant factor not exceeding 1,8. Tests using these series of concentration should allow the LC50 value and its confidence limits to be estimated as precisely as possible. In the definitive test at least four test batches per concentration and four untreated controls, each with 10 worms, are used. The results of these replicate batches are given as a mean and standard deviation.
Rozpätie koncentrácií spôsobujúcich mortalitu od 0 do 100 % môže byť stanovené v teste na vyhľadávanie rozsahu, pri ktorom sa získajú informácie o tom, ktoré koncentrácie sa použijú v konečnom teste.
When two consecutive concentrations, at a ratio of 1,8, give only 0 % and 100 % mortality, these two values are sufficient to indicate the range within which the LC50 falls. Mixture of the basic test substrate and the test substance The test substrate should, whenever possible, be made up without any additional agents other than water. Immediately before the start of the test, an emulsion or dispersion of the test substance in deionised water or other solvent is mixed with the basic test substrate, or sprayed evenly over it with a fine chromatographic or similar spray. If insoluble in water, the test substance can be dissolved in as small a volume as possible of suitable organic solvent (e.g. hexane, acetone or chloroform). Only agents which volatilise readily may be used to solubilise, disperse or emulsify the test substance. The test substrate must be ventilated before use. The amount of water evaporated must be replaced. The control should contain the same quantity of any additive agent. If the test substance is not soluble, dispersible or emulsifiable in organic solvents, 10 g of a mixture of fine ground quartz sand and a quantity of test substance necessary to treat 500 g dry weight of artificial soil are mixed with 490 g of dry weight of test substrate.

If this is not possible because of the 1 % of LC50 criterion and the analytical limit, a lower factor than ten can be used or the use of 14C labelled test substance should be considered. No concentration used should be above the solubility of the test substance.
Ak to z dôvodu kritéria 1 % hodnoty LC50 alebo analytického prahu nie je možné, potom možno použiť faktor nižší ako 10 alebo treba uvažovať o označení testovanej látky izotopom14 C. Nesmú sa používať koncentrácie, ktoré sú vyššie ako rozpustnosť testovanej látky.

Rainbow trout (Oncorhynchus mykiss) is the recommended species for this test since most experience has been gained from ring-test with this species (1)(2). However, other well documented species can be used but the test procedure may have to be adapted to provide suitable test conditions.
Pstruh dúhový (Oncorhynchus mykiss) je odporúčaným druhom na tento test odvtedy, čo sa v skupinových testoch získalo dostatočné množstvo skúseností s týmto druhom (1), (2).
A ring-test (2) has shown that, for rainbow trout, a loading rate of 16 trouts of 3-5 g in a 40-litre volume is acceptable. Recommended frequency of water removal during the test is 6 litres/g of fish/day.

The test is begun by placing fertilised eggs in the test chambers and is terminated just before the yolk-sac of any larvae in any of the test chambers has been completely absorbed or before mortalities by starvation start in controls. Lethal and sub-lethal effects are assessed and compared with control values to determine the lowest observed effect concentration and hence the no observed effect concentration.
Test začína umiestnením oplodnených vajíčok do testovacej komory a končí práve predtým, ako ktorákoľvek z lariev v ktorejkoľvek testovanej komore komplexne absorbuje žĺtkový vak alebo pred uhynutím v dôsledku začínajúceho hladovania v kontrolnej komore.
Where egg containers, grids or meshes have been used to hold eggs within the main test vessel, these restraints should be removed after the larvae hatch [13] OECD, Paris, 1992, Test Guideline 210, ‘Fish, Early-life Stage Toxicity Test’. , except that meshes should be retained to prevent the escape of the fish.
Ak sa v hlavnej testovacej nádobe na zadržiavanie vajíčok použili kontajnery, mriežky alebo sieťky, potom po vyliahnutí lariev môžu byť tieto zábrany odstránené [2] s výnimkou, ak mriežky preventívne zabraňujú úniku rýb.
The use of fewer than five concentrations, for example in limit tests, and a narrower concentration interval may be appropriate in some circumstances. Justification should be provided if fewer than five concentrations are used.
Za určitých okolností je vhodné použiť menej ako päť koncentrácií, napr. v limitných testoch a v užších koncentračných intervaloch.

The use of non-labelled test substances with known composition and preferably at least 95 % purity or of radiolabelled test substances with known composition and radio-purity, is recommended. In the case of short half-life tracers, decay corrections should be applied.
Odporúča sa použitie neoznačkovaných testovacích látok so známym zložením aspoň 95 % čistoty alebo u rádiooznačených látok o známom zložení a rádio-čistoty v prípade krátkej polovičnej doby rozpadu by sa mali aplikovať korekcie na rozpad.
The analytical methods which can be used for sorption measurements include gas-liquid chromatography (GLC), high-performance liquid chromatography (HPLC), spectrometry (e.g. GC/mass spectrometry, HPLC/mass spectrometry) and liquid scintillation counting (for radiolabelled substances). Independent of the analytical method used, it is considered suitable if the recoveries are between 90 % and 110 % of the nominal value.
Medzi analytické metódy, ktoré môžme použiť na sorpčné merania, patria chromatografia plyn – kvapalina (GLC), vysoko účinná kvapalinová chromaografia (HPLC), spektrometria (GC/hmotnostná spektrometria – plynová chromatografia v kombinácii s hmotnostnou spektrometriou), HPLC/hmotnostná spektrometria – kvapalinová chromatografia v kombinácii s hmotnostnou spektrometriou) a kvapalné scintilačné počítadlo (na látky označené rádioaktívnou látkou).

Areas which are more difficult to deal with are those where the chemical is highly or very slightly adsorbed. Where low adsorption occurs, a 1:1 soil/solution ratio is recommended, although for some very organic soil types smaller ratios may be necessary to obtain a slurry. Care must be taken with the analytical methodology to measure small changes in solution concentration; otherwise the adsorption measurement will be inaccurate.

In case the concentration in the aqueous phase is given on a weight/volume base then the units are ml· g-1. Kd can vary with sorbent properties and can be concentration dependent.
V prípade koncentrácie vo vodnej fáze je daná na základe hmotnosť/objem, potom jednotky sú ml.g-1.Kd sa môže meniť s vlastnosťou sorbentu a môže byť závislé od koncentrácie.
As a result of partitioning between mobile and stationary phases the test substance is retarded. The dual composition of the stationary phase having polar and non-polar sites allows for interaction of polar and non-polar groups of a molecule in a similar way as is the case for organic matter in soil or sewage sludge matrices.
Dvojité zloženie stacionárnej fázy, ktorá má polárny aj nepolárny charakter, umožňuje interakcie pólových aj nepólových skupín v molekule podobnou cestou ako v prípade organickej látky v pôdach alebo v splaškovo kalových matriciach.
Lowest Observed Effect Concentration (LOEC): is the lowest tested concentration at which the substance is observed to have a statistically significant effect on reproduction and parent mortality (at p < 0,05) when compared with the control, within a stated exposure period. However, all test concentrations above the LOEC must have a harmful effect equal to or greater than those observed at the LOEC. When these two conditions cannot be satisfied, a full explanation must be given for how the LOEC (and hence the NOEC) has been selected.
Najnižšia zistená účinná koncentrácia (LOEC): je najnižšia testovaná koncentrácia, pri ktorej je badateľný štatisticky významný efekt tejto látky na reprodukciu a rodičovskú mortalitu (v p < 0,05), keď porovnávame s kontrolou v medziach stanoveného času pôsobenia.
At the end of the test, the total number of living offspring produced per parent animal alive at the end of the test is assessed. This means that juveniles produced by adults that die during the test are excluded from the calculations.
Na konci testu sa odhaduje celkový počet živého potomstva vyprodukovaného rodičovským živočíchom, ktorý prežil do konca testu, to znamená, že mláďatá vyprodukované dospelými jedincami, ktorí uhynuli počas testu, sú vylúčené z výpočtov.
For this reason, a fully defined medium is desirable. However, at present, the only fully defined media which are known to be suitable for long-term culture of Daphnia magna are Elendt M4 and M7.
Z tohto dôvodu sa vyžaduje úplne definované médium, v súčasnosti sú však iba Elendt M4 a M7 plne definované médiá, ktoré sú vhodné na dlhožijúce kultúry Daphnia magna.
For the estimation of the LOEC, and hence the NOEC, for effects of the chemical on reproductive output, it is necessary to calculate the mean reproductive output across replicates for each concentration and the pooled residual standard deviation, and this can be done using analysis of variance (ANOVA). The mean for each concentration must then be compared with the control mean using an appropriate multiple comparison method.
Na odhad LOEC ako aj na NOEC na vplyvy chemikálií na reprodukčný výstup je potrebné vypočítať významný reprodukčný výstup cez replikáty cez každú koncentráciu a združené reziduálne štandardné odchýlky, môže sa to vykonať za použitia analýzy rozptylu (ANOVA).

Having regard to Commission Regulation (EC) No 1529/2007 of 21 December 2007 opening and providing for the administration of import quotas for rice originating in the States that make up the Cariforum region and the overseas countries and territories (OCT) [3], and in particular Article 4(1) thereof,
so zreteľom na nariadenie Komisie (ES) č. 1529/2007 z 21. decembra 2007, ktorým sa otvára a ustanovuje správa kvót na dovoz ryže s pôvodom v štátoch, ktoré sú súčast’ou oblasti Cariforum, a zámorských krajinách a územiach (ZKÚ) [3], a najmä na jeho článok 4 ods. 1,
Regulation (EC) No 1529/2007 opened an annual import tariff quota for 2008 of 187000 tonnes of rice, in husked-rice equivalent, originating in States that are part of the Cariforum region (serial number 09.4219), an import tariff quota of 25000 tonnes of rice, in husked-rice equivalent, originating in the Netherlands Antilles and Aruba (serial number 09.4189) and an import tariff quota of 10000 tonnes of rice, in husked-rice equivalent, originating in the leastdeveloped OCTs (serial number 09.4190).
Nariadením (ES) č. 1529/2007 sa otvorila na rok 2008 ročná dovozná colná kvóta na 187000 ton ryže, vyjadrené v ekvivalente lúpanej ryže, s pôvodom v štátoch, ktoré sú súčast’ou regiónu Cariforum (poradové číslo 09.4219), dovozná colná kvóta na 25000 ton ryže, vyjadrené v ekvivalente lúpanej ryže, s pôvodom v Holandských Antílách a Arube (poradové číslo 09.4189) a dovozná colná kvóta na 10000 ton ryže, vyjadrené v ekvivalente lúpanej ryže, s pôvodom v najmenej rozvinutých ZKÚ (poradové číslo 09.4190).
For these quotas, provided for in Article 1(1) and 2 of Regulation (EC) No 1529/2007, the second subperiod is the month of May.
Pre tieto kvóty ustanovené v článku 1 ods. 1 a 2 nariadenia (ES) č. 1529/2007 je druhým čiastkovým obdobím mesiac máj.
The information provided in accordance with Article 6(a) of Regulation (EC) No 1529/2007 shows that in the case of the quota with serial number 09.4219 applications lodged during the first seven days of May 2008 in accordance with the first subparagraph of Article 2(1) of that Regulation cover a quantity in husked-rice equivalent greater than the quantity available.
Z oznámenia podľa článku 6 písm. a) nariadenia (ES) č. 1529/2007 vyplýva, že žiadosti podané podľa prvého pododseku článku 2 ods. 1 uvedeného nariadenia počas prvých siedmich dní mesiaca mája 2008 sa pre kvótu s poradovým číslom 09.4219 vzťahujú na také množstvo vyjadrené v ekvivalente lúpanej ryže, ktoré prekračuje dostupné množstvo.
