Abstract
Acute and whole life-cycle toxicity tests were conducted with the estuarine mysid shrimp, Mysidopsis bahia, exposed to cyanide and selected heavy metals. Acute toxicity values (96h LC50) ranged from 3.5 micrograms/1 for mercury to 3130 micrograms/1 for lead, and were ranked in order of toxicity: (greatest)Hg, Cd, Cu, Cn, Ag, Sn, Ni, As, Cr, Pb(least). The chronic toxicity values ranged from 1.2 micrograms/1 for mercury to 893 micrograms/1 for arsenic. Chronic values were calculated from either survival, time to first reproduction, or number of young produced. When acute toxicity data for the same chemical are compared, M. bahia is consistently among the more sensitive marine species. Lack of comparable data precludes a similar observation with chronic tests. Examination of the relative sensitivity of the chronic responses indicates that only for cadmium was survival more sensitive than reproduction.
