Micropol

Introduction

The MICROPOL group of the CES&T brings together several UGent research groups working on the occurrence, analytics, behavior, distribution, toxicity, risks and treatment of micropollutants in the environment (water, air, soil).

Micropollutants (including emerging contaminants) are of increasing worldwide concern and consist of a wide range of anthropogenic and natural substances, including trace elements (metals and metalloids), volatile organic compounds (VOCs), pesticides, pharmaceuticals, personal care products, industrial chemicals, and hormones. Micropollutants are typically present in the environment at (ultra-)trace concentrations. Their low concentration often complicates analysis, treatment, and risk assessment, not the least because they often occur in complex mixtures and matrices.

Research groups

The MICROPOL group of the CES&T currently brings together 7 research groups (and their expertise):

Acronym Research unit Expertise
GhEnToxLab Ghent University Environmental Toxicology Unit Ecotoxicology, stress ecology and risk assessment of micropollutants
EnVOC Environmental Organic Chemistry and Technology Chemical trace analysis of (non-)volatile organics and emerging micropollutants, air and water treatment
CMET Center for Microbial Ecology and Technology The study and application of mixed microbial cultures or communities
BIOMATH Mathematical Modelling, Statistics and Bioinformatics Model-based process analysis and optimisation
PainT Particle and Interfacial Technology group Fundamental studies and applications of physico-chemical separation processes for water treatment
ECOCHEM Laboratory of Analytical Chemistry and Applied Ecochemistry Environmental and analytical chemistry of trace elements (metals and metalloids)
LIWET Laboratory for Industrial Water and Ecotechnology Scale-up of water treatment processes
