(N/A) Agricultural pollutants like industrial wastewater,pesticides,and fertilizers are the main sources of soil pollution.
It is crucial to maintain soil quality and fertility to sustain vegetation. Insecticides like $DDT$ are persistent in the soil because they are not easily degraded. Pesticides such as $Aldrin$ and $Dieldrin$ are non-biodegradable and highly toxic to the environment.
These pollutants enter the food chain and cause health issues. Similarly,industrial waste contains toxic heavy metals like $Pb, Hg, Cd,$ and $As$,which contaminate the soil.
To control soil pollution,we should:
$1$. Periodically monitor soil quality.
$2$. Treat industrial wastewater using proper procedures before discharging it.
$3$. Minimize the use of synthetic pesticides and fertilizers,opting for organic alternatives.
