To evaluate the possibility of heavy metal emission from aluminum recycling craft village activities in Man Xa village, Van Mon, Bac Ninh, heavy metals (Cd, As, Pb, Zn) in the solid waste, soil, air dust were determined by ICP-MS equipment during November - December 2021. Among the heavy metals studied, Pb was an element with high concentration that exists in all three environment components: solid waste, soil, and ambient air. 9/28 samples, accounting for 30% of the total number of samples analyzed with Pb concentration was exceeded QCVN 07:2009/BTNMT (regulations on hazardous waste thresholds) for both total and leaching extraction methods and those samplers were identified as hazardous waste. In addition, 3/28 samples had Zn level exceeding the allowable limit, 1/28 sample had Cd level exceeding the allowable limit and were hazardous waste. Moreover, all 4 air dust samples have heavy metal concentrations exceeding the allowed standards, 4 heavy metal concentrations in 4/6 soil sampler were exceeded the allowed standard by 1.2-3 times. The research results show the high level of heavy metal pollution in solid waste, soil, and air dust from aluminum recycling activities due to lack of management and treatment action of solid waste and air.
