Study of pm10 bound heavy metals in ambient air of dewas industrial area, Madhya Pradesh, India

Heavy metals in ambient air mostly bound with the particulate matter can cause harm to health if its concentration increases. The study of PM10 bound heavy metals i.e. Chromium (Cr), Manganese (Mn), Copper (Cu), Zinc (Zn), Cobalt (Co), Cadmium (Cd), Iron (Fe), Lead (Pb), Nickel (Ni) and Arsenic (As) in ambient air atmosphere of Dewas industrial area, Madhya Pradesh, India has been done. Among of all heavy metals mainly three metals i.e. Pb, Ni and As were reported as pollutants in National Ambient Air Quality Standards 2009. Lead (Pb) was found within standard limit (0.5 µg/m3) at all monitoring locations except A1 (1.054 µg/m3) and A2 (1.64 µg/m3) locations, Nickel (Ni) was found exceeded standard limit (20 µg/m3) at all monitoring locations except A9 (11.48 ng/m3) and Arsenic (As) was found within standard limit (6 µg/m3) as per National Ambient Air Quality Standards of India (2009) at all monitoring locations around Dewas industrial area. Based on the study, Dewas Industrial area found polluted w.r.t. heavy metals viz., Ni and Pb in ambient air.
