Xenobiotic substances in solid matrices of aquatic ecosystems
Monitoring of substances such as halogenated and other hazardous organic pollutants or heavy metals provides valuable information about environmental pollution. These persistent substances accumulate in both biotic and abiotic compartments, as well as in food chains, and many of them act as human carcinogens and endocrine disruptors. The Czech Hydrometeorological Institute’s annual monitoring results show long-term contamination of surface water ecosystem in the Czech Republic by these substances.
Juvenile fish assemblages – appropriate tool for monitoring of the ecological status
Aquatic organisms have a very good ability to reflect the conditions of the environment they live in and, therefore, they are often used to assess the ecological status of that particular environment. of juvenile fish assemblages (0+) represent an appropriate tool for monitoring the ecological status of watercourses as they show a very rapid response to changes in environmental conditions. The goal of this study was to assess assemblages of juvenile fish (0+) at 22 sites across the Czech Republic between 2019 and 2021.
25 years of systematic groundwater quality monitoring in the Czech Republic
Many professionals deal with water quality monitoring in the Czech Republic with various goals and various quality of gathered information. The Czech Hydrometeorological Institute (CHMI) has built and developed a unified longterm monitoring system providing comparable high quality data at a nation- al scale.
