The lysosomal stability as a biomarker for the determination of pollution in aquatic environments.

摘要

This work studied the effects caused by five different formulae of gasoline on the stability of the lysosomes isolated from the liver of the tilapia fish (Oreochromis niloticus). The functional integrity of the lysosomal membranes was evaluated via the acid phosphatase activity. The results showed that there were significant changes in the stability of the lysosomes exposed to the presence of the hydrocarbons in the environment. Therefore, considering the method's simplicity, the sensitivityof the responses and its low cost the assessment of the lysosomal activity could be an important tool for the study of the effects of pollution in the aquatic environments.
