24、) 3 Introduction This International Standard describes a method for the determination of the acute toxicity of contaminated soils and chemicals to the larvae of Oxythyrea funesta, a phytophagous coleopteran (Scarabaeidae, Cetoniinae) with wide geographic distribution (Europe, North Africa and the Mi

25、ddle East). Oxythyrea funesta has many characteristics which make it suitable for soil quality monitoring or testing effects of chemicals: ecological relevance: this type of organism contributes in many ways to soil structure by stimulating soil aeration and drainage; the first stages of development

26、, i.e. incubation of eggs, larval cycle and pupation, are underground; the larvae of Oxythyrea funesta are tolerant to modifications of the test substrate granulometry; this species can be bred under controlled conditions. DIN EN ISO 20963:2011-09 EN ISO 20963:2011 (E) 4 1 Scope This International S

27、tandard describes a method for the determination of the effects of contaminated soils and substances on the survival of the larvae of Oxythyrea funesta. The larvae are exposed to the pollutants by cuticular and alimentary uptake. For contaminated soils, the effects on the survival are determined in

28、the test soil and in a control soil. Depending on the objectives of the study, the control and dilution substrates (dilution series of contaminated soil) are either uncontaminated soil comparable to the soil sample to be tested or artificial soil substrate. Effects of substances are assessed using a

29、 defined artificial soil substrate. This International Standard is not applicable to volatile substances, i.e. substances for which Henrys constant or the air/water partition coefficient is greater than 1, or for which the vapour pressure exceeds 0,001 33 Pa at 25 C. NOTE This method does not take i

30、nto account the possible degradation of the substances or pollutants during the test. 2 Normative references The following referenced documents are indispensable for the application of this document.

33、itions For the purposes of this document, the following terms and definitions apply. 1) To be published. (Revision of ISO 11269-2:1995) DIN EN ISO 20963:2011-09 EN ISO 20963:2011 (E) 5 3.1 lethal concentration 50 LC 50 median lethal concentration of test substance or percent dilution of contaminated

34、 soil, which kills 50 % of the test organism within the test period 3.2 lethal concentration x LCx concentration of the test substance or percent dilution of contaminated soil which kills x % of the test organism within the test period NOTE x is the percentage (10, 20, 25) of this effect. 3.3 Lowest

35、 Observed Effect Concentration LOEC lowest tested concentration of test substance or contaminated soil at which a statistically significant effect is observed compared with the control NOTE All test concentrations above the LOEC have a harmful effect equal or greater than those observed at the LOEC.

36、 3.4 No Observed Effect Concentration NOEC highest tested concentration of test substance or contaminated soil at which no statistically significant effect is observed compared with the control NOTE The NOEC is the test concentration immediately below the LOEC. 3.5 test mixture mixture of the test s

37、ubstance with the test substrate, mixture of contaminated soil with the test substrate or mixture of contaminated soil with an uncontaminated soil comparable to the soil sample to be tested 3.6 diapause interruption of metabolism during egg, larva, pupa or imago development 4 Principle Larvae of Cet

38、oniinae (species Oxythyrea funesta) are exposed to a dilution range of contaminated soil or to a range of concentrations of test substance. The mortality of larvae is determined after 10 days. Test mixtures are prepared at the start of the test and are not renewed within the test period. The results

39、 obtained from the test are compared with a control and are used to determine the concentration which causes mortality of 50 % of the larvae (LC 5010days). The test is conducted in two steps: a preliminary test to determine appropriate dilution/concentration range in the final test; the definitive t

40、est to determine the dilutions/concentrations causing between 10 % and 90 % mortality, which yields the test result. DIN EN ISO 20963:2011-09 EN ISO 20963:2011 (E) 6 It may also be possible to determine the effects of contaminated soils or substances on the growth of larvae (optional). The increase

41、in mass within the test period allows this criterion to be considered as complementary to mortality, in order to assess the effects of contaminated soils or substances. 5 Test environment Tests shall be performed at a temperature of (26 1) C in complete darkness. 6 Reagents 6.1 Biological material T

42、he species used in the test is Oxythyrea funesta (Scarabaeidae, Cetoniinae). Third-instar larvae with a fresh mass within the range 100 mg to 200 mg are required to perform the test. The larvae shall be healthy, without any bites or other visible injuries. NOTE Depending on the breeding conditions,

43、described in Annex A, larvae approximately two weeks old are suitable for the test. Larvae of similar size shall be selected. The difference in mass between the smallest and the largest larva within a single test container shall not exceed 50 mg. Eliminate the particles of breeding substrate stuck t

44、o the integument using, for example, a soft brush before weighing the larvae. It is also possible to leave the animals to move along on slightly moist paper in order to eliminate the breeding substrate stuck to the integument. Synchronisation of breeding is necessary. An example of breeding techniqu

45、e for Oxythyrea funesta is given in Annex A. 6.2 Test substrate The mass of substrate used per glass container (7.1) shall be equivalent to 300 g (dry mass). The substrate, called artificial soil, shall have the following composition (in accordance with ISO 11268-1): sphagnum peat, air-dried, finely

46、 ground and with no visible plant remains: 10 % (expressed on a dry mass basis); kaolinite clay containing not less than 30 % kaolinite: 20 % (expressed on a dry mass basis); industrial quartz sand (dominant fine sand with more than 50 % particle size between 0,05 mm and 0,20 mm): 70 % (expressed on

47、 a dry mass basis). Add pulverised calcium carbonate (CaCO3), of recognised analytical grade, as necessary to bring the pH of the wetted substrate to 6,0 0,5 (commonly between 0,5 % and 1 % of the mass of the dry ingredients). Prepare the artificial soil by mixing the dry constituents listed above t

48、horoughly in a large-scale laboratory mixer. The amount of calcium carbonate required can vary, depending on properties of the individual batch of sphagnum peat, and should be determined by weighing subsamples immediately before the test. Store the mixed artificial soil at room temperature. To deter

49、mine pH and the maximum water-holding capacity, pre-moisten the dry artificial soil at least two days before starting the test by adding deionized water to obtain half of the required final water content of 50 % of the maximum water-holding capacity. DIN EN ISO 20963:2011-09 EN ISO 20963:2011 (E) 7 Determine the water-holding capacity in accordance with ISO 11269-2:, Annex A, and pH in accordance with ISO 10390. If the measured pH is not within
