Abstract
Samples of used drilling muds collected during the course of a single well drilling operation exhibited different degrees of acute toxicity to sheepshead minnows and grass shrimp. For moulting grass shrimp, Palaemonetes pugio, the 96-h LC50's were 360 to 14560 ppm (micro 7 litre); many of these values were considerably lower than those reported from previous drilling mud assays. However, when some of the muds in this study were tested on sheepshead minnows, Cyprinodon variegatus, the resulting 96-h LC50 (6300 to 1000000 ppm) were well within the range of previously reported values.
