SENSITIVITY OF AN INFAUNAL AMPHIPOD, EOHAUSTORIUS ESTUARIUS, TO ACUTE WATERBORNE EXPOSURES OF 4-NONYLPHENOL: EVIDENCE OF A TOXIC HANGOVER

Three independent trials were conducted using mortality and burial as endpoints. Amphipod mean lethal concentration to 50% (LC50) was 227 mu g/L. One- hour burial as a sublethal endpoint increased the sensitivity of the toxicity test by 40%; however, most amphipods that survived exposure were able t...

Description
Summary:Three independent trials were conducted using mortality and burial as endpoints. Amphipod mean lethal concentration to 50% (LC50) was 227 mu g/L. One- hour burial as a sublethal endpoint increased the sensitivity of the toxicity test by 40%; however, most amphipods that survived exposure were able to recover within 24 to 48 h. This toxic hangover was dose-dependent.
