The concns. of polycyclic arom. hydrocarbons (PAH) in air in the Netherlands showed a significant decline during 1974-1981, after reaching the peak values in 1965-74. The strong decrease in PAH concns. resulted from the replacement of coal by natural gas as fuel for domestic heating. The growth of automotive traffic d. did not interfere with the downward trend of atm. PAH concn. in towns.
