The effects of a linear alkylate sulfonate detergent on the snail, Helisoma trivolvis (Say), were studied over a fifteen week period which extended from August 22 to December 3, 1967. Six adult snails were kept in each of eight containers which contained three liters of the test solution. These solution concentrations were: 0 ppm (control), 10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 ppm, 60 ppm and 70 ppm of linear alkylate sulfonate detergent. The test containers were kept in a room with natural lighting and the temperature was allowed to fluctuate with that of the environment. It was found that the detergent increased the viability of the eggs, increased the time needed for hatching and produced a direct relationship between the strength of the concentration and the mortality rate. It appears that concentrations of 20 ppm or more would prohibit survival of this species.
