Abstrak
Mazkur maqolada Toshkent viloyatining Yangiyo‘l va Piskent tumanlari tuproqlarida og‘ir metallar bilan ifloslanish darajasi baholandi. Tadqiqotlar sanoat manbasi hisoblangan Olmaliq tog‘-kon metallurgiya majmuasiga yaqin hududlarda olib borildi. Tuproq namunalarida Pb, Cd, As, Cr, Ni, Cu, Zn va boshqa kimyoviy elementlar miqdori aniqlandi. Natijalarga ko‘ra, Piskent tumani Xaydarov massivida Cd, As, Pb va Zn elementlari me’yordan sezilarli oshganligi qayd etildi. Yangiyo‘l tumani tuproqlarida esa ifloslanish darajasi nisbatan o‘rtacha ekanligi aniqlandi. Tuproqlarning ekologik holati Soil Quality Index (SQI) usuli asosida baholanib, Piskent tumanida texnogen ta’sir darajasi yuqori ekani tasdiqlandi. Olingan natijalar texnogen omillarning tuproq kimyoviy tarkibi va agroekotizim barqarorligiga salbiy ta’sir ko‘rsatadi. Ayniqsa Cd, Pb va As elementlari ekologik xavf nuqtayi nazaridan ustuvor ahamiyatga ega ekani aniqlandi.
