Ecosystems Research

Dalizza Colón

My current research aims to improve the understanding of biological transformations of organic pollutants in aquatic and terrestrial systems to ultimately develop quantitative structure activity relationships (QSARs), which can be used to predict the biotic rates of reaction of environmentally relevant organic chemicals in natural aerobic environments. In particular, this work focuses on the fate of pollutants used in agricultural activities, consumed by humans, and/or that are classified as high production volume chemicals in natural systems. These QSARs are useful in the (i) prediction of environmental concentrations of organic chemicals and their transformation products in the natural environment, (ii) evaluation of spatially-explicit chemical exposures to protect the human health and the environment, and (iii) assessment of ecological and management of chemical risks.
