Water quality. Determination of acute toxicity of water samples and chemicals to a fish gill cell line (RTgill-W1) Ingestion-build-183098 BS EN IEC 60947‑7‑4 providesWhat is this standard about? This document specifies a method for the determination of fish acute toxicity using the permanent cell line from rainbow trout (Oncorhynchus mykiss) gill, RTgill W1. Cells in confluent monolayers in 24 well tissue culture plates are exposed to water samples, such as surface waters or different kinds of effluents, or to chemicals for 24 h and, thereafter, cell viability is assessed based on fluorescent cell viability
