g akkumulyatsiyasi daryo suvining ikkilamchi ifloslanish manbaiga aylanish xavfini tug‘diradi. nowadays, the pollution of water resources and the accumulation of contaminants in sediments are among the major global environmental problems. the zarafshan river is one of the key hydro-ecosystems in uzbekistan, and its water quality is significantly affected by industrial and domestic discharges. the accumulation of heavy metals and other toxic substances in bottom sediments poses a risk of becoming a secondary source of water pollution. materiallar va usullar / materials and methods tadqiqotlar zarafshon daryosining samarqand viloyati hududidagi qismida olib borildi. daryoning turli nuqtalaridan cho‘kindi (sediment) namunalar olindi. namunalarda og‘ir metallar – pb, cd, zn, cu va cr miqdori atom-absorbsiya spektrometriyasi yordamida aniqlangan. the research was conducted on the section of the zarafshan river located in the samarkand region. sediment samples were collected from various points along the river. the concentrations of heavy metals (pb, cd, zn, cu, and …

he concentration of heavy metals may lead to their desorption into the water, increasing the risk of secondary pollution. xulosa / conclusion tadqiqot natijalari shuni ko‘rsatdiki, zarafshon daryosi tubida og‘ir metallar ma’lum miqdorda to‘planib, suvning ikkilamchi ifloslanish xavfini keltirib chiqarmoqda. samarqand viloyati hududidagi cho‘kindi namunalarida aniqlangan ifloslanish darajasi o‘rtacha deb baholandi. daryoda ekologik monitoring tizimini kuchaytirish va ifloslanish manbalarini kamaytirish bo‘yicha tavsiyalar ishlab chiqildi. the results of the study revealed that heavy metals are accumulated in the bottom sediments of the zarafshan river, creating a potential risk of secondary water pollution. the level of contamination in the sediment samples collected from the samarkand region was assessed as moderate. recommendations were developed to strengthen the environmental monitoring system and reduce pollution sources in the river. foydalanilgan adabiyotlar / references 1. boyd, c. e.
