Summary
Heavy metal content in soils and vegetables in the Hanoi peri-urban area
8 heavy metals were analysed in vegetables: Cu, Zn, Pb, Cd, Cr, Hg, As; Pb and Cd should be warned a possible contamination because they exist at/and or higher than maximum limit (Việt Nam standard 1998/WHO 1993). In Tu Liem, Pb content in 13 vegetable samples (in 18 samples) was detected at higher maximum limit. In Thanh Tri, Pb content in 7 vegetable samples (in 8 samples) has higher maximum limit. Cd content: 11 samples in Tu Liem (in 18 samples) have higher maximum limit. 3 samples in Thanh Tri (in 8 samples) were found at higher maximum limit. No correlation between heavy metal content in soil and vegetable was found, therefore reason of high heavy metal content in vegetables is a question to be study deeper.
