HEAVY METALS CONTENTS IN SOIL AND WATER ENVIRONMENTFROM THE AGRICULTURAL AREAS (FLOWERS – VEGETABLES – FRUITS) IN PHU DIEN AND TAY TUU DISTRICTS (HA NOI)

Abstract

The accumulation of heavy metals in the soil and water environment from agricultural activities affects not only the development of crops but also more seriously, to the human and animal health through the food chain. This paper presents the analytical results of heavy metals such as Cr, Mn, Ni, Cu, Pb, Cd, As, Sb and Zn in the soil and water environment of the cultivated areas (vegetables - flowers – fruits) in the Phu Dien and Tay Tuu districts. The results showed that the concentrations of most heavy metals were still under the allowed values of the Vietnamese standards for irrigation water. But in the cultivated soil, the As and Cu contents averaged 76.5 µg/g and 14.7 µg/g respectively, exceeded the allowed values of the Vietnamese

standards.
