[Blood serum lipoproteins in overhaul workers of the chemical plant at Jaworzno].

For the evaluation of fat metabolism in 45 overhaul workers of a chemical plant producing pesticides, the serum concentration of total cholesterol and its LDL nd HDL fraction (also HDL2 and HDL3), apolipoprotein A and B, phospholipids and triglycerides were estimated. As compared to the results in the control group of healthy inhabitants of the region, occupationally not exposed to chemical agents, higher levels of total and LDL cholesterol, apolipoprotein A, total and LDL phospholipids, as well as triglycerides were found. Serum HDL2 cholesterol concentration was also, though insignificantly elevated. Such lipoprotein distribution can promote atherogenesis.
