Acute Toxicity Of The Organochloride Insecticide, Toxaphene, To Grass Shrimp, Palaemonetes Pugio
Abstract
Laboratory bioassays were conducted with toxaphene to determine its toxicity and LC₅₀ for grass shrimp, Palaemonetes pugio. Tests were conducted at 10, 19 and 100 ppb at 25°C and 10, 19 and 23 ppb at 30°C. The 24 hour LC₅₀ was 57 ppb, 48 hour LC₅₀ was 15 ppb and 72 hour LC₅₀ was 13 ppb at 25°C and 48 hour LC₅₀ was 11 ppb at 30°C.
Post-mortem measurements of the rostrum-telson length of shrimp showed an increase with every 24 hour period for each assay in most cases, but were not significant at one standard deviation.
