Abstrak
Og‘ir metallarning tuproqqa tushgandan keyingi holati uning tuproq muhitiga qanday ta’sir qilayotganini ko‘rsatuvchi belgilardan biri hisoblanadi. Tuproqning organik va anorganik fraksiyalarda tarqalishiga ko‘ra, metallarning birikish turlari ham turlicha bo‘ladi. Buni Olmaliq kon-metallurgiya kombinati atrofida tarqalgan tuproqlar misolida o‘rganilganda, tuproqning organik qismi, ya’ni tuproq gumusiga hududlar bo‘ylab qanday ta’sir qilgani tekshirildi.
