Specific problems of environmental protection in Central Europe and dense industrialization in Poland that is powered by traditional power plants and having developed heavy industry, have resulted in a need for a special environmental protection policy. Reliable methods are needed to analyze low concentrations of trace elements in pollutants existing in atmospheres, precipitates, ground waters and soils. A knowledge of trace-elements concentration can help in setting industrial limits for emission, permanent control of emission perturbations and finally epidemiological studies. During recent years, methods based on the x-ray fluorescence phenomenon were being widely developed in Poland. Now due to the development of cyclotrons, proton-induced x-ray emission appears to be very useful for pollutant control.
