Production of nitrate fertilizers began at the factory near Pulawy in 1966. Air pollution caused by this plant has caused rapid decay of the pine forest surrounding it. Lichens have been completely eliminated for up to 11 km, distance varying with wind pattern. Destruction is largely attributed to aerosol dusts of ammonia and ammonium nitrate. Sulfur dioxide levels are elevated in the region of the plant, but are not considered excessive.
