BIOMONITORING - Assessment of contamination in aquatic environment with passive sampling and juvenile fish analyses
Topic of the practice
Assessment of contamination in aquatic environment
Good Practice Information
In the context of the Water Framework Directive (WFD) presence and concentrations of hazardous substances such as heavy metals and polyaromatic hydrocarbons (PAHs) are of high importance. For assessment of their contamination, biomonitoring techniques by passive sampling and juvenile fish analyses have been used successfully.
Passive sampling is based on free flow of contaminants from water to a collecting medium. Juvenile fish stay on a restricted area during their first summer and thus reflect contaminants in local conditions. The methods can be used to detect occasional pollution over a longer time span than the typical water samples representing one moment.
Evidence of success
The methods are successfully used in Czech national biomonitoring programme in analysing a broad spectra of contaminants. The methods detect cost-effectively contaminants, which are difficult to identify by contemporary water sampling. Methods may give early warning and provide possibility to identify sources of contamination.
