Search line summary 


The general objective of the line is to study the impact that different types of pollutants can produce on the aquatic and terrestrial environment, either in natural communities or at the laboratory level.

In the evaluation of the ecological impact different parameters or aspects can be taken into account such as the effects on the survival and the behaviour of the species of organisms, the incidence at the level of metabolism on some general and specific biomarkers of certain functions
