This European Standard gives guidance for sampling, preservation, storage, quantification and qualitative analysis of phytoplankton from marine waters. Guidance for quantification is limited to the use of light microscopy with phase-contrast and epifluorescence.This European Standard specifies: the development of the sampling programme; requirements for sampling equipment; procedures for sampling and treatment of samples in the field; methods for quantification; qualitative analysis.This European Standard describes minimum requirements for environmental monitoring.

This International Standard describes the kinetic direct-contact method for determining the inhibitory effect of suspensions of sediment and other solid samples, and also for problematic turbid or coloured aqueous samples on the light emission of the marine bacterium Vibrio fischeri (NRRL B-11177).This method is applicable to:. sediment samples and water suspensions of sediments (fresh water, brackish, and seawater sediments);. effluents (especially turbid and coloured);. aqueous extracts (e.g. leachates, eluates, elutriates) of soil, solid waste, and other solid material(especially turbid and coloured).

This International Standard specifies a method for determining the toxicity of environmental samples on growth, fertility and reproduction of Caenorhabditis elegans. The method described is applicable to whole fresh water sediment (maximum salinity 5 0/00), soil and waste, as well as to pore water, elutriates and aqueous extracts, that were obtained from contaminated sediment, soil, and waste.

Results from the test method suggest, within the confines of a controlled laboratory setting, the degree of aerobic aquatic biodegradation of a lubricant or components of a lubricant by measuring the evolved carbon dioxide upon exposure of the test material to an inoculum. The plateau level of CO2 evolution in this test method will suggest the degree of biodegradability of the lubricant. Test substances that achieve a high degree of biodegradation in this test may be assumed to easily biodegrade in many aerobic aquatic environments. Because of the stringency of this test, a low yield of CO2 does not necessarily mean that the test substance is not biodegradable under environmental conditions, but indicates that further testing is necessary to establish biodegradability. Information on toxicity to the inoculum of the test substance may be useful in the interpretation of low biodegradation results. Activated sewage-sludge from a sewage-treatment plant that principally treats domestic waste is considered an acceptable active aerobic inoculum available over a wide geographical area in which to test a broad range of lubricants. An inoculum derived from soil or natural surface waters, or both, or any combination of the three sources, is also appropriate for this test method. Note 18212;Allowance for various and multiple inoculum sources provides access to a greater diversity of biochemical competency and potentially represents more accurately the capacity for biodegradation. A reference or control substance known to biodegrade is necessary in order to verify the activity of the inoculum. The test must be regarded as invalid and should be repeated using a fresh inoculum if the reference does not demonstrate a biodegradation of > 60 % of the theoretical CO2 evolution within 28 days. A total CO2 evolution in the blank at the end of the test exceeding 75 mg CO2 per 3 L of medium shall be considered as invalidating the test. The water solubility or dispersibility of the lubricant or component may influence the results obtained and hence the procedure may be limited to comparing lubricants or components with similar solubilities. The ratio of carbon incorporated into cellular material to carbon released as CO2 will vary depending on the organic substrate, on the particular microorganisms carrying out the conversion, and on the environmental conditions under which the conversion takes place. In principle, this variability complicates the interpretation of the results from this test method.1.1 This test method covers the determination of the degree of aerobic aquatic biodegradation of fully formulated lubricants or their components on exposure to an inoculum under laboratory conditions. 1.2 This test method is intended to specifically address the difficulties associated with testing water insoluble materials and complex mixtures such as are found in many lubricants. 1.3 This test method is designed to be applicable to all lubricants that are not volatile and are not inhibitory at the test concentration to the organisms present in the inoculum. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards are discussed in Section 10.

WARNING — Persons using this International Standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. IMPORTANT — It is absolutely essential that tests conducted according to this International Standard be carried out by suitably trained staff. SAFETY PRECAUTIONS — Activated sludge and sewage contain potentially pathogenic organisms. Therefore take appropriate precautions when handling them. Handle toxic test compounds and those whose properties are unknown with care. This International Standard specifies a method for the evaluation of the “ready” and “ultimate” biodegradability of organic compounds at a given range of concentrations by aerobic microorganisms. In this context, this International Standard also gives specific definitions for the terms “ready” and “ultimate”. The method applies to organic compounds which are: a) soluble at the concentration used under the conditions of the test [dissolved organic carbon (DOC) concentrations of 10 mg/l to 40 mg/l]; b) non-volatile or having a negligible vapour pressure under the conditions of the test; c) not significantly adsorbable on glass and activated sludge; d) not inhibitory to the test microorganisms at the concentration chosen for the test. The method is not suitable for waste waters, as they usually contain significant amounts of water-insoluble organic carbon, which is not included in DOC measurements.
