ISO 19820:2016 specifies a method for the determination of the lethal effects of toxicants to Brachionus plicatilis after 24 h or 48 h exposure. The method is applicable to the following: a) chemical substances which are soluble or which can be maintained as a stable suspension of dispersions under the conditions of the test; b) industrial or sewage effluents, treated or untreated, if appropriate after decantation, filtration, or centrifugation; c) marine or estuarine waters; d) sediment elutriates/eluates.

1.1 This guide covers some general information on methods for qualitative and quantitative assessment of the behavioral responses of fish during standard laboratory toxicity tests to measure the sublethal effects of exposure to chemical substances. This guide is meant to be an adjunct to toxicity tests and should not interfere with those test procedures. 1.2 Behavioral toxicosis occurs when chemical or other stressful conditions, such as changes in water quality or temperature, induce a behavioral change that exceeds the normal range of variability (1). Behavior includes all of the observable, recordable, or measurable activities of a living organism and reflects genetic, neurobiological, physiological, and environmental determinants (2). 1.3 Behavioral methods can be used in biomonitoring, in the determination of no-observed-effect and lowest-observedeffect concentrations, and in the prediction of hazardous chemical impacts on natural populations (3). 1.4 The behavioral methods described in this guide include locomotory activity, feeding, and social responses, which are critical to the survival of fish (4). 1.5 This guide is arranged as follows: Section Number Scope 1 Referenced Documents 2 Terminology 3 Summary of Guide 4 Significance and Use 5 Interferences 6 Safety Precautions 7 Responses Measured 8 Test Organisms 9 Facility 10 Qualitative Behavioral Assessment Method 11 Quantitative Behavioral Measurements 12 Experimental Design 13 Calculation of Test Results 14 Report 15 1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. For an explanation of units and symbols, refer to IEEE/ASTM SI 10. 1.7 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. While some safety considerations are included in this guide, it is beyond the scope of this guide to encompass all safety requirements necessary to conduct behavioral toxicity tests. Specific hazards statements are given in Section 7. 1.8 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.

This document specifies a method for determining the toxicity of environmental samples on growth, fertility and reproduction of Caenorhabditis elegans. The method applies to contaminated whole freshwater sediment (maximum salinity 5 g/l), soil and waste, as well as to pore water, elutriates and aqueous extracts that were obtained from contaminated sediment, soil and waste.

What is BS EN 17218 - Mesozooplankton sampling about? BS EN 17218 discusses mesozooplankton sampling from marine and brackish water. BS EN 17218 specifies procedures for the sampling of mesozooplankton using nets and continuous ribbon-sampling devices in marine and brackish waters for the purpose of water quality assessment and determination of the ecological status of ecosystems. Guidance on sampling procedures and the subsequent steps of preservation and storage are given. The sampling procedures allow estimates of species occurrence and their abundance (relative or absolute), including spatial distribution and seasonal and long-term temporal trends, for a given body of water. The described methods are restricted to the sampling of mesozooplankton that inhabit marine and brackish waters and exclude the shallow littoral zones which require a different type of sampling (e.g., zooplankton in salt marshes). Who is BS EN 17218 - Mesozooplankton sampling for? BS EN 17218 on mesozooplankton sampling is used by: Government laboratories
