Chronic sensitivity of white sturgeon (Acipenser transmontanus) and rainbow trout (Oncorhynchus mykiss) to cadmium, copper, lead, or zinc in laboratory water‐only exposures

摘要: Chronic toxicity of cadmium, copper, lead, or zinc to white sturgeon (Acipenser transmontanus) and rainbow trout (Oncorhynchus mykiss) was evaluated in water-only exposures started with newly hatched larvae approximately 1-mo-old juveniles. The 20% effect concentration (EC20) for cadmium from the tests higher than EC20 tests, whereas were lower those EC20s trout. When present study included compiled databases all freshwater species, species mean chronic value a relatively low percentile sensitivity distribution copper (9th percentile) middle (55th percentile), (40th lead (50th percentile). However, high (∼68th–82nd but (23rd each 4 metals above US Environmental Protection Agency ambient water quality criteria (AWQC) Washington State standards (WQS), equal below AWQC WQS. In addition, acute 50% concentrations (EC50s) obtained first d test final used derive WQS copper. Environ Toxicol Chem 2014;33:2246–2258. Published 2014 Wiley Periodicals Inc. on behalf SETAC.
