Cholinesterase can take place in aquatic organisms under a series of environmental adverse conditions. The study of cholinesterases in these organisms can give important information about their physiological status and about environmental health. However, it is very important to know how the environmental factors such as fluctuation of physicochemical parameters associated to the presence of pollutants might affect these cholinesterase activities. We studied the response of cholinesterase activity in the caged cockle Cerastoderma glaucum. In addition, we evaluated the potential uses of cholinesterase activity in the common sole, which inhabit the Tunisian coast, subjected to different stress conditions, such as the exposure to different contaminants. This review summarizes the data obtained in some studies carried out in organisms from the Tunisian aquatic environment.

Keywords: Cholinesterases, Environmental stress, Biomonitoring, Aquatic Environments.

A colinesterase está presente nos organismos aquáticos em condições de stress ambiental. O estudo da colinesterase fornece informações acerca da condição fisiológica e saúde ambiental. Contudo é importante averiguar de que modo os factores ambientais, tais como a flutuação dos parâmetros físico-químicos, associados à presença de poluentes afectam a actividade das colinesterases. Neste trabalho são apresentadas os níveis de actividade da colinesterase em
Cerastoderma glaucum. São ainda apresentados os potenciais usos da actividade das colinesterases na solha comum que habita a costa Tunisina. Este trabalho sumariza também os resultados obtidos até agora em outros organismos estudados na Costa Tunisina.

Palavras-chave:Colinesterases, Stress Ambiental, Biomonitorização, Ambientes Aquáticos.
