目前,西孟加拉地区地下水砷污染问题日益严重并且已经波及到食物链中。由于吸收了砷污染地下水,谷物和蔬菜中砷含量日渐累积,超出了健康规定范围。尽管提出了若干补救方案,但是考虑到农业人口的社会经济状况,建议使用地表水灌溉方案。然而,实际中该方案仍然较难施行,且并无其他更经济有效的措施。若干年后,含水层可以减缓严酷的健康环境现状并为人们提供安全的饮用水。
At present, the problem of groundwater arsenic contamination in West Bengal is worsening and has spread to the food chain. Due to the arsenic-contaminated groundwater, the arsenic content of cereals and vegetables is increasing, which is beyond the scope of the health regulations. Although a number of remedial options have been proposed, the use of surface water irrigation schemes is recommended given the socio-economic status of the agricultural population. However, in practice the scheme is still difficult to implement and there are no other more cost-effective measures. Years later, aquifers can slow down the harsh health conditions and provide people with safe drinking water.
