SN/T 4155-2015 in English

This standard provides detailed guidelines for conducting toxicity tests using artificial water or sediment spiked with test substances. It outlines the procedures for assessing the impact of chemicals on the life cycle of chironomids, which are commonly used as indicator organisms in environmental toxicity studies. The document specifies the preparation of test materials, experimental conditions, and data recording methods to ensure consistency and reliability in test results. It also includes requirements for sample collection, storage, and analysis. The standard aims to establish a uniform approach for evaluating the potential ecological risks associated with chemical substances in aquatic environments.
