Abstract
Fluorosis is still a serious public health problem in China according to our field investigation. Current foodstuff drying methods were studied to evaluate the state of foodstuff contamination, including burning mixed coal (MC)/coal washing wastes (CWWs)/lump coal (LC)/fuelwood/fine coalâ¯+â¯fixing materials (FCFM)/CWWsâ¯+â¯fixing materials (CFM) in open stove (OS), honeycomb briquettes (HB) in improved stove (IS), sun-drying. The results demonstrate that elemental contents of F, As, Cd, Cr and Pb in roasted grain were 1.19-40.65 times higher than limting standard. The comprehensive risk of different drying methods based on AHP-FCE is ranked in the order of: CWWs(OS)â¯>â¯MC(OS)â¯>â¯HB(IS)â¯>â¯CFM(OS)â¯>â¯FCFM(OS)â¯>â¯LC(OS)â¯>â¯Fuelwood(OS)â¯>â¯sun-drying. It exhibits obviously higher risk due to burning CWWs/MC in OS than other methods. Burning CFM/FCFM/fuelwood in OS may be an economic and relatively safe foodstuff drying methods.
