Extract

A study has been made of the toxicities of mercuric chloride, mercuric iodide and methyl-, ethyl-, n-propyl-, n-butyl-, n-amyl-, iso-propyl-, iso-amyl- and phenylmercuric chlorides to larvae of the crustaceans Artemia salina and Elminins modestus. With both species it has been found that all the mercury compounds are more toxic than mercuric chloride, that primary alkylmercuric chlorides are more toxic than the corresponding secondary compounds, and that as the homologous series of primary compounds is ascended, toxicities increase. In addition, it has been found that Elminius is much more readily poisoned than Artemia by each mercury compound, and that differences between the toxicities of the poisons to Elminius are much smaller than corresponding differences observed in experiments with Artemia.
