Arsenic Incorporation into Garden Vegetables Irrigated with Contaminated Water

摘要

Daily vegetable requirement are mostly fulfilled in Bangladesh through homestead gardenproduction which are usually irrigated with arsenic-rich underground water. Garden vegetables grown inarsenic-tainted soil may uptake and accumulate significant amount of arsenic in their tissue. Mean, minimumand maximum arsenic content in some common garden vegetables, e.g. bean, bitter gourd, bottle gourd, brinjal,chilli, green papaya, mint, okra, palwal, potato, red amaranth, string bean and sweet gourd, from an arsenicpronelocality of Bangladesh have been assessed. The contribution of vegetable-arsenic in the daily diet wasestimated. Correlation with the groundwater arsenic status and statistical significance of variations has beendiscussed.
