Trace elements in scalp hair of manufacturers of fireworks from Sivakasi, Tamil Nadu.

The concentrations of Cd, Cr, Cu, Mn, Ni and Pb were analysed by AAS in the hair of male and female, controls and workers from firework cottage industries from Sivakasi, Tamil Nadu. When compared with controls, significantly higher levels of Mn and Cr were found in male healthy workers and unhealthy workers with chronic headaches and dizziness. In the case of female workers, higher Mn and lower Pb levels were found, but the level of any element was not significantly different in the workers with ulcers and asthma. There is a possibility of occupational exposure of both male and female workers to the risk of Cr and Mn pollution.
