Aquatic environments cover 71% of the earth’s surface. Water is an indispensable component of life, and its preservation is of vital importance. The increasing and continuous development of socio-economic activities linked to urban planning, agriculture, industry, transport and tourism, has led to a degradation of the Algerian coastal marine environment. The various pollutants result for 80% from land-based activities and 20% from marine activities.
The first part aims at defining a handful of concepts and present biomonitoring tools. In the second part, the lecture is illustrated by an example of water quality monitoring using several biomarkers of environmental stress that have been successfully tested, among them two new ones.
The third part examines the impact of pollution on a target species (Donax trunculus). Finally, the fourth part is devoted to the analysis of heavy metals (Mn, Zn, Cu, Pb, Cd) in the sediments and flesh of this species and an evaluation of consumption risks on public health.
