Environmental contamination processes are extremely critical in relation to the impacts caused as well as the identification of pollutant source(s).


A critical, accurate and confidential assessment performed using appropriate tools, is therefore essential to provide accurate information to public entities, organizations and/or companies involved. Corporate accountability is a vital process which significantly impacts an institution’s budget and image.


In this context, our multidisciplinary team uses a wide range of advanced techniques, including isotopic fingerprints, to investigate potential pollutant sources with the necessary resolution and detail, in cases of suspected environmental contamination.

Particulate material for urban atmosphere


This type of evaluation allows the identification and detection of particle sources in the air of cities and/or metropolitan areas, as well as quantifying the contribution of the main sources.

This information can be complemented by emissions inventory studies and atmospheric shaping.
