BS EN 17204:2019 水质 海洋和咸水中型浮游动物分析指南

What is BS EN 17204 – Analysis of mesozooplankton about?    BS EN 17204 is an international standard that deals with the aspects of maintaining water quality.   BS EN 17204 specifies a procedure for analyzing mesozooplankton in marine and brackish waters. The procedure comprises how to identify and enumerate mesozooplankton to estimate quantitative information on diversity, abundance, and biomass about the spatial distribution and long-term temporal trends for a given body of water.   BS EN 17204 gives you technical specifications such as terms, principles, equipment, preservatives and other chemicals, test procedures, etc., for the analysis of mesozooplankton. It also specifies the reporting and quality assurance for maintaining the water quality.   Who is BS EN 17204 – Analysis of mesozooplankton for?   BS EN 17204 on A...

ASTM D5259-19 用膜过滤法从水中分离和计数肠球菌的标准试验方法

1.1 This test method covers a membrane filter (MF) procedure for the detection and enumeration of the enterococci bacteria in water. The enterococci, which include Enterococcus faecalis (E. faecalis), E. faecium, and their varieties are commonly found in the feces of humans and other warmblooded animals. Although some strains are ubiquitous and not related to fecal pollution, enterococci in water are an indication of fecal pollution and the possible presence of enteric pathogens. These bacteria are found in water and wastewater in a wide range of densities. The detection limit is one colony forming unit (CFU)/volume filtered. 1.2 This test method has been used successfully with temperate fresh and marine ambient waters, and wastewaters. It is the user’s responsibility to ensure the validity of this test method for waters of untested types. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are included for information only and are not considered standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ISO 21115:2019 水质.水样和化学品对鱼鳃细胞系（RTgill-W1）急性毒性的测定

This document specifies a method for the determination of fish acute toxicity using the permanent cell line from rainbow trout (Oncorhynchus mykiss) gill, RTgill-W1. Cells in confluent monolayers in 24- well tissue culture plates are exposed to water samples, such as surface waters or different kinds of effluents, or to chemicals for 24 h and, thereafter, cell viability is assessed based on fluorescent cell viability indicator dyes (see 4.1). Data are then expressed as a percentage of unexposed control and toxicity quantified based on the percentage of cell viability versus the percentage of effluent or the chemical concentration in response curves (see Clause 9).

BS EN ISO 10634:2018 水质 难溶于水的有机化合物的制备和处理 用于随后评估其在水介质中的生物降解性

What is this standard about? This document specifies techniques for preparing poorly water-soluble organic compounds (i.e. liquid and solid compounds) with a solubility in water of less than approximately 100 mg/l and introducing them into test vessels for a subsequent biodegradability test in an aqueous medium using standard methods. The subsequent tests on biodegradability are primarily methods using the analysis of the released carbon dioxide described in ISO 9439 and the determination of the oxygen described in ISO 9408 and following the usual precautions for ISO 10707. Thus, one can notice that the methods measuring the removal of dissolved organic carbon (DOC) are not appropriate. This document does not specify the biodegradation test methods. It is restricted to describing techniques for introducing the test compounds into the test medium and to keeping them in a dispersed state[4]. These techniques are implemented while observing the experimental conditions described in the standardized methods for evaluating biodegradability. ISO 9439, based on CO2 evolution, is not suitable for testing volatile compounds. Some of the preparation methods described in this document might not be accepted by regulators for making conclusions on the ready biodegradability of tested compounds. Examples of biodegradability curves are given in this document.
