THE POSSIBILITY OF HEAVY METAL ACCUMULATION IN TO LICH RIVER WATER, IRRIGATION WATER, CULTIVATION LAND AND VEGETABLE PRODUCTS IN BANG B HAMLET, THANH TRIDISTRICT, HANOI, VIET NAM

PHAM THI TO OANH AND VU DUC TOAN

Abstract

Hanoi is the capital city of Vietnam, with a high population density, and a concentration of industrial, manufacturing and processing facilities. To Lich river has a length of 14 km, receiving sewage from other rivers and the end streams are used to pump for irrigation of vegetables, supplying for people in Hanoi. The analysis results of heavy metal content (Pb, Cd, Zn, Cu, Hg, CrTS, As) at 2 different times for samples of surface water in To Lich river, irrigation water, vegetable land and vegetable products (especially water vegetables) in Bang B hamlet, Thanh Tri district, Hanoi, Vietnam show that most of the samples have content of heavy metals in April 2003 much lower than in April, 2019: surface water 1.42-48.6 times lower, vegetable water 1.36-64 times lower, cultivation land 2.26-37 times lower and vegetables 3.02-38.1 times lower. The ability to store heavy metals in a cycle from surface water, irrigation water, soil and vegetables is related to the distant, position, different kinds of vegetable, content and time, affecting the quality of vegetable products and public health.
