UNE-EN ISO 15088-2009 PDF

Full title and description

UNE-EN ISO 15088:2009 — Water quality — Determination of the acute toxicity of waste water to zebrafish eggs (Danio rerio). This document is the Spanish (UNE) adoption of ISO 15088:2007 and specifies a laboratory method to determine dilutions or concentrations of wastewater that produce an acute toxic effect on zebrafish eggs within a 48-hour exposure period, applicable to treated municipal and industrial effluents as an alternative/complimentary method to traditional fish acute tests.

Abstract

Specifies a standardized procedure using Danio rerio (zebrafish) eggs to assess acute toxicity of whole effluents and wastewater samples. The method defines test setup, control requirements, dilution series, observation endpoints (egg viability/mortality over 48 h), data reporting and interpretation so results can be used for effluent monitoring, compliance checks or comparative ecotoxicological assessment.

Scope

Provides a method for determining the acute toxic effect of wastewaters on early life stages (eggs) of Danio rerio over 48 hours. The scope covers whole-effluent testing and treated municipal or industrial effluents and is intended as a standardized approach that can give comparable results to other fish acute tests while reducing the need for tests on older life stages in some contexts. The method specifies test acceptance criteria, controls and reporting to support regulatory and monitoring uses.

Key topics and requirements

• Test organism and stage: fertilised eggs of Danio rerio (zebrafish).
• Exposure period and endpoints: acute assessment over a 48-hour exposure with mortality/viability as primary endpoints (detailed observations and reporting required).
• Test conditions and quality control: guidance on controls, reference toxicant, dilution series, temperature and water quality to ensure valid results.
• Sample handling and preparation: procedures for effluent sampling, storage and pre-treatment prior to testing.
• Data analysis and reporting: calculation of effect concentrations (where applicable), test validity criteria and recommended reporting elements for regulatory acceptance.

Typical use and users

Environmental testing laboratories, wastewater treatment operators, environmental regulators, consultants and ecotoxicologists use this method to screen whole effluents for acute toxic effects, to support compliance monitoring, impact assessments and comparative testing of treatment performance. The test can be used alongside other standards and guidelines in ecotoxicity programs.

Related standards

Closely related to the originating ISO standard (ISO 15088:2007). Relevant companion and comparison documents include the ISO fish-acute test series (e.g., ISO 7346 series) and internationally recognized embryo/egg test guidelines such as OECD Test Guideline 236 (Fish Embryo Acute Toxicity, FET), which address related endpoints and may be used in parallel or as alternatives depending on regulatory context.

FAQ

Q: What is this standard?

A: UNE-EN ISO 15088:2009 is the Spanish national adoption of ISO 15088 (originally published by ISO in 2007), giving a standardized laboratory method to determine acute toxic effects of waste water on zebrafish eggs (48 h test).

Q: What does it cover?

A: It covers test design, control and reference requirements, dilution series, observation endpoints (egg viability/mortality), data analysis and reporting for whole-effluent acute toxicity testing using Danio rerio eggs. It is intended for treated municipal and industrial effluents and comparable monitoring scenarios.

Q: Who typically uses it?

A: Environmental laboratories, wastewater utilities, regulatory agencies, ecotoxicologists and consultants performing effluent screening, compliance checks and impact assessments.

Q: Is it current or superseded?

A: ISO 15088 is an international standard published in 2007 and national adoptions appeared in 2009; users should confirm the current national/ISO lifecycle status with the national standards body or ISO because review/supersession/withdrawal can occur at the national level. (National adoption documents and confirmation records should be checked for the most current status.)

Q: Is it part of a series?

A: It relates to the broader suite of water-quality and fish-toxicity standards (for example ISO 7346 series for fish acute tests) and to embryo/egg test guidelines such as OECD TG 236 (FET). These related documents are commonly referenced together when designing aquatic ecotoxicity testing programs.
