      The combustion of fossil fuels may introduce some toxic elements into the atmosphere and more lead has been transferred to the air by use of TEL as an antiknock additive in gasoline.
      These substances have contaminated life support system such as food, air, water and soil large enough concentrations to produce acute or chronic illness.
      Our concern has focused on oils(bunker C, distillate fuel oil and gasoline) and coals in 17 mines which are located in Gangweon-do, Chungcheong-nam-do, Gyengsang-bug-do, Jeonla-nam-do, From oils and coals concentration of Pb were measured with atomic absorption spectrophotometer and results were analysed as follow.
      1. Mean concentration for Pb in coals was 12.85㎍/g (7.5∼22.9).
      2. Mean cocentration for Pb in crude oil was 1.8㎍/㎖, in bunker C oil 0.6㎍/㎖, in distillate fuel oil 0.5㎍/㎖, gasoline 0.47㎍/㎖.
      3. Emitted amount of Pb from bunker C oil and gasoline in the year of 1990 in Seoul was estimated to be 22.04×10^(5)g.
