The effects of storage temperature and time on sediment toxicity

The effects of storage at different temperatures on contaminated estuarine sediment toxicity were evaluated over a 20-week period. In 96-h suspended particulate phase tests with the mysid shrimp, Mysidopsis bahia, toxicity increased with time for samples stored at 4 and -22 degree C. Survival was re...

Description
Summary:The effects of storage at different temperatures on contaminated estuarine sediment toxicity were evaluated over a 20-week period. In 96-h suspended particulate phase tests with the mysid shrimp, Mysidopsis bahia, toxicity increased with time for samples stored at 4 and -22 degree C. Survival was reduced from 40% at week zero to less than 10% at week 12 for both temperature regimes. Relative sensitivity to sodium dodecyl sulfate, used as a reference toxicant, was similar at all time intervals except for week 20 when decreased sensitivity was recorded.
