Ecotoxicology

How much exposed to pollutants are birds, and what are the consequences?

Human activities frequently lead to the introduction of contaminants into natural environments that can affect the health, reproduction and survival of wild birds. These contaminants may be chemicals, and the list is growing rapidly, such as persistent organic pollutants (POPs), anticoagulants or metal trace elements (TMEs). The large quantities of plastic released into the environment are also a major concern, as they break down into microplastics and release chemicals such as phthalates. This project aims to quantify exposure to pollutants in wild bird populations and elucidate their impact on health and fitness.

Project objectives

We are currently studying the exposure and consequences of persistent organic pollutants in the Alpine swift and trace metals in the dipper. We are also seeking to develop measures of exposure to microplastics in dippers and to rodenticides in barn owls.

Methodology

We are working to understand which tissues should be used to measure exposure to pollutants in birds while minimising the effects of sampling, and are collaborating with laboratories across Europe to measure pollutants using state-of-the-art facilities.
