Arsenic content in smokeless tobacco products consumed by the population of Pakistan: related health risk.

Extensive investigation has shown that smokeless tobacco (SLT) may cause inflammation of the oral cavity. In this study, the concentration of arsenic (As) was determined in SLT products (gutkha, mainpuri, and dry and moist snuff). Scalp hair samples of males aged 20-30 years who consumed different types of SLT products available in Pakistan were analyzed for As contents.
