Detailed study areas

The sampling density is higher in the detailed study areas compared to the rest of the country. In most cases, the number of analysed elements is also higher in the detailed study areas, and in addition to arsenic and metal concentrations, concentrations of organic PAH and PCB compounds are available from some areas. Additional information on detailed study areas is available by using the Statistics tool in the detailed study area.
