Influence of feeding and organism age on the acute toxicity of sodium bromide to Artemia salina

Bromide is a common ion found in freshwater and marine systems. Although normally at relatively low concentrations, higher levels may occur point-released wastewaters as well nonpoint runoff from agricultural or industrial locations where bromide compounds are used biocides disinfectants. In this study, the potential toxicity of NaBr saltwater environment was studied using brine shrimp, Artemia salina. The confounding factors organism age test initiation pre-test feeding were included design. Survival shrimp nauplii several treatments up to 11,000 mg Br−/L (measured) assessed after 24 h both fed- unfed-tests. tests with unfed organisms, only youngest ( old result excessive control mortality an invalid test. These studies show that, when healthy organisms tests, 11,000 mg/L Br− (~14,200 mg/L NaBr) not acutely toxic
