Tóm tắt

Tình trạng ô nhiễm các kim loại nặng ở các khu vực khai thác quặng là rất nghiêm trọng hiện nay ở Việt Nam cũng như trên thế giới. Đánh giá mức độ và nguy cơ ô nhiễm của asen (As) trong đất ở khu vực khai thác quặng là rất cần thiết đối với việc quản lý môi trường. Phân tích hàm lượng tổng số và dạng hóa học của As trong các mẫu đất được thực hiện theo quy trình chiết Tessier và thiết bị ICP-MS. Nồng độ trung bình của As trong 5 mẫu đất bãi thải là 10,14 ÷ 44,68 mg/Kg và trong 7 mẫu đất nông nghiệp là 5,66 ÷ 7,65 mg/Kg. As trong 12 mẫu đất phân tích đều tồn tại chủ yếu trong các mẫu đất ở dạng cặn dư (F5) > dạng cacbonat (F2) > dạng oxit Fe/Mn (F3) > dạng hữu cơ (F4) > dạng trao đổi (F1). Theo tiêu chuẩn Việt Nam, nồng độ của As trong các mẫu đất nông nghiệp đều thấp hơn giới hạn cho phép, và 3/5 mẫu đất bãi thải có nồng độ As thấp hơn giới hạn cho phép trong đất nông nghiệp và 2 mẫu đất bãi thải có nồng độ As cao hơn giới hạn cho phép. Theo chỉ số Igeo, hầu hết các mẫu đất đều có giá trị Igeo ở mức ô nhiễm nhẹ. Theo mã đánh giá mức độ rủi ro (RAC) thì 10/12 mẫu đất phân tích nằm ở mức rủi ro trung bình.

Tóm tắt tiếng anh

The pollution of heavy metals in ore mining areas is severe at present in Vietnam as well as in the world. Assessing the level and risk of contamination of arsenic (As) in the soil in the ore mining area is essential for environmental management. The total content and chemical fractions of As in the soil samples were performed according to Tessier’s extraction procedure and using the ICP-MS method. The average concentration of As in the 5 tailing samples ranged f-rom 10.14 ÷ 44.68 mg kg-1 and in the 7 agricultural samples was 5.66 ÷ 7.65 mg/Kg. In the investigated soil samples, As was found mainly in the fractions of residues (F5) > carbonate (F2) > Fe/Mn oxides (F3) > Organic carbon (F4) > exchangeable fraction (F1). According to Vietnamese standards, the concentration of As in agricultural soil samples was all lower than the allowable limit, while 3/5 of the tailing samples had As concentrations less than the permissible limit in agricultural soil and the other 2 samples had As concentrations higher than the allowable limit. According to the Igeo index, most soil samples had Igeo values at a mildly contaminated level. According to the Risk Assessment Code (RAC), 10/12 soil samples analyzed were at medium risk.
