Human health risk assessment of heavy metals in roadside dust near hydropower dams construction areas in Wangduephodrang District of Bhutan
Abstract:
The concern over the heavy metal laden dust and its impact on human health has gained global importance over the decade. Exposure to roadside dust is associated with various acute and chronic health issues. Bhutan too is battling environmental health issues due to increasing anthropogenic and developmental activities such as hydropower dam construction. This study analyses the heavy metals concentrations in roadside dust near hydropower dam construction areas and assesses the noncancer and cancer risk of exposure to heavy metals laden dust through inhalation. This study was a cross sectional study. The roadside dust samples near hydropower dam construction in Wangduephodrang District were collected and analyzed for As, Pb, Cr, and Hg concentration by using ICP-OES. The socio demographic data and exposure factors were collected through interviews. The mean concentration of the heavy metals in the dust samples were Cd
