摘要

不加区分的工业化和城市化对我们的环境造成了负面影响。印度半城市地区常见的环境问题之一是将未经有效处理的市政、工业和家庭废水排放到环境中,导致土壤和水质退化。淡水资源的枯竭促使印度农民以废水的形式寻找一种容易获得、更便宜、营养丰富的灌溉水源;然而,这也导致了污染物向土壤转移的增加。镉(Cd)、铜(Cu)、铬(Cr)、铅(Pb)、汞(Hg)等重金属被称为持久性污染物,由于其不可生物降解的性质、延长的生物半衰期和生物相互作用,它们具有潜在的危害。这些重金属可以附着在土壤表面,然后被植物组织吸收。

Heavy metals in agricultural cultivated products irrigated with wastewater in India: a review
Indiscriminate industrialization and urbanization have negatively impacted our environment. One of the common environmental problems in semi-urban areas in India is the discharge of inefficiently treated municipal, industrial, and domestic wastewater into the environment, resulting in the degradation of soil and water qualities. Depleting freshwater resources have led Indian farmers to look for an easily available, cheaper, and nutrient-rich source of irrigation water in the form of wastewater; however, this also led to increased pollutant transfer to the soils. Known as persistent pollutants, heavy metals such as cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), mercury (Hg), and a few others are potentially hazardous due to their nonbiodegradable nature, extended biological half-lives, and biological interactions. These heavy metals can bind to soil surfaces and then be absorbed by plant tissues.
