Soils and Environmental Research Unit – LGCgE

In 2012, ISA Lille environmental science research unit integrated into a regional laboratory to form LGCgE (Laboratory of Civil and geoEnvironmental Engineering).

Increasing urbanization, intensive agriculture as well as the industrial past of our region guided the research thematic of the laboratory on the management of soils which are affected at various levels by anthropogenic activities.

Scientific and technical arguments have been given to help the conservation and the improvement of soil quality with environmental and healthy preoccupations for many years.

The working-out of a geochemical report on agricultural soils, the study of the soils contamination by MTE (Metallic Trace Elements), the behaviour of these elements in soils and their transfer mechanisms to biosphere and mankind, the contribution to the remediation and management of soils contaminated by MTE are the main research axis of the laboratory.
