Problems of heavy metal come from the factories have imperfect precaution to pretect distribution to environment. Heavy metal concentrations in soil may be elevated considerably when metal sewage sludge from Battery Plant is spread on land. At present, Manganese are most important metal that found to be the problems when the workers are exposed by pollution from Battery Plant. Soil and sewage samples taken from Battery Plant in Bangkok Metropolitan area. The heavy metals determined are manganese and zinc. The amounts of Mn and Zn, in soil, found as high as are 1,200 ppm - 300,000 ppm and 350 ppm - 53,750 ppm, respectively. In sewages found as high as are 20,100 ppm - 336,250 ppm and 25,000 ppm - 72,000 ppm, respectively when comparison to control soil samples (Mn, 76 ppm - 260 ppm; zn 1.49 ppm - 11.90 ppm). A comparison of the concentration changing amounts of three seasons (Summer, Rainy and Winter) is also given. The results show that amount of Mn and Zn in soils and sewages did not change significantlyat 5% level.
