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 acute WET tests, the small planktonic crustacean,
Daphnia magna, an inhabitant of freshwaters, is employed as a test organism and exposed to various effluent concentrations under controlled conditions for a short duration (48 h). This helps to estimate the effluent′s toxicity and arrive at the lethally toxic concentrations of the effluent.
