Indiscriminate release of industrial wastewater/mining wastes
into the water bodies and reuse of this polluted wastewater for agriculture
purpose is a topic of debate for sustainable development.
These wastewater containing heavy metals (density of >5 g
cm-3) in toxic levels is of great health concern for human and animal
through food web.
Durgapur Industrial Belt (DIB) of India is discharging effluents into the
Tamala Drain (TD) leading to metal pollution of water-soil system and also
affects biota of the area.
Locals farmers are using for cultivating food crops, pulses
and vegetables because they are ignorant about the hidden toxicity of the
factory discharged and their subsequent negative impacts such as loss of soil
fertility/crop yield, bioconcentration of metals in edible parts or forage
plants.
