一般描述

This Whole Effluent Toxicity (WET) proficiency testing sample is produced in accordance with ISO/IEC 17043:2010. This sample is manufactured according to TNI requirements. However, please note, this sample may include non-TNI analytes as well.

In the acute WET test, Sheepshead minnow is employed as a test organism and is exposed to various effluent concentrations. The toxicity of wastewater effluents is estimated for a specific time period. This method is used to test the effect of effluents in wastewaters, which have a negative impact on the aquatic ecosystems.

Supelco^?is a global proficiency testing (PT) provider that manufactures best-in-class environmental and pharmaceutical PT products. Most water PT samples are available as concentrates or ready-to-use volumes giving the end-user flexibility in selecting samples that will fit their exact needs. Our PT program is designed to meet the quality assurance requirements in compliance with Discharge Monitoring Report - Quality Assurance Program (DMR-QA), thereby ensuring the analytical competence of your laboratory.

Analyte/s:Values of analytes vary lot to lot.

All information regarding the use of Sheepshead minnow (Cyprinodon variegatus), 48-hr Acute, nonrenewal, 25℃, SSW proficiency testing standard can be found in the reporting packet which will be available to download at PT Portal.

制备说明

Description

The effluent is provided as a concentrate for dilution in synthetic seawater.
This concentrate is an EPA-specified toxicant in reagent-grade DI water.
Enough material has been provided to run the method at least twice.
Do not deviate from the supplied instructions or EPA Method 2004.0.
Contact ptservice@milliporesigma.com before running the test if you see the need to deviate from the test conditions.
Deviations may affect your final evaluation.

Preparation Instructions

To prepare 1 L of effluent, add 900 mL of synthetic seawater to a volumetric flask.
Preparation instructions for synthetic seawater can be found in the EPA document EPA-821-R-02-012, page 31.
Transfer the entire contents of one container to the flask.
Rinse the container with synthetic seawater and transfer to the volumetric flask. Bring flask to 1 L volume with synthetic seawater.
This represents 1 L of effluent water for the test.
