Protocol for a Small-scale Algal Toxicity Assay for Testing the Acute Toxicity of Plastic Leachates v1

2025
Gillian Champoir

Summary

This protocol describes a small-scale algal toxicity assay using glass culture tubes (to avoid plastic contamination) and fluorescence-based growth measurement to assess the acute toxicity of plastic leachates on algae over two weeks.

This protocol uses glass culture tubes as opposed to a well plate to avoid potential plastic contamination. The assay runs for two weeks or longer if so desired. Instead of using cell counts, fluorescence is used as a proxy for growth rate, as it can be calculated into µ upon completion of the experiment.
