Abstract

Red-tide toxicants were evaluated based on the following requirements: 100% lethality to Gymnodinium breve within 24 hours at concentrations of 0.01 p.p.m. or less and a selectivity threshold concentration at 0.1 p.p.m. Chemicals that killed 50% or more of any test organism (juvenile forms of marine species living in Galveston Bay) within 24 hours or below this concentration were rejected. Five chemicals passed these requirements: carbamic acid, dietheyldithio-, tellurrium salt; carbamic acid, dimethyldithio-, ferric salt; disulfide, bis (dithylthiocarbamyl); sulfide, bis (2-hydroxy-3-bromo-5-chlorophenyl)- bis dimethylamino butyne monosalt; sulfide, bis (2-hydroxy-3-bromo-5chlorophenyl)- bis dimethylamino butyne monosalt and sulfide, bis (2-hydroxy-3-bromo-5chlorophenyl)-, cyclohexylamine monosalt.(DBO)
