Organic micropollutants originate from many sources and are harmful to living organisms. They can be medicaments, pesticides, herbicides, and others. Many of them are persistent, bioaccumulative and toxic even in very low amount. In a one-year campaign the concentration of many hundreds of such substances was measured in surface waters, soil samples and wastewater treatment plants (both municipal and industrial) accross Hungary. The task is the statistical analysis of the database and to compare the level of the pollutants to those in other regions and to the standards. An affinity to chemistry is needed.
