Analyze Possible Changes in the Approximate Composition of Exposed Organisms and Study the Physiological Effects of a Given Toxic Substance on Biological Indicators

Abstract

The toxicological response of estuarine benthic macroinvertebrate (as bio-indicators) to toxicants can be assessed by analyzing possible alterations of the proximate composition of the exposed organism. Any alteration to the proximate composition may be as a result of the impact of a given toxicant to the physiology of the bio-indicator. This study has revealed that P. aurita is able to tolerate sublethal doses of extracts of K. grandifoliola without major alterations to its proximate composition.
