A Bioassay Dilution Technique to Assess the Significance of Dredged Material Disposal.

Abstract

A laboratory procedure for assessing the potential biological impact of open-water disposal of dredged material is described. The procedure incorporates a serial dilution technique based on dye diffusion studies. This approach is necessary because the effect of a discharge is a function of exposure time and effective exposure concentration, and dredged material perturbations are generally of short duration compared with the time intervals specified in conventional bioassays. The results demonstrate that stimulatory or inhibitory materials do not have a significant effect on an algal population when the rate of dilution at an open-water site is considered.
