Fertilizers.
Farmers put fertilizers on their crops and then the fertilizer can get washed into the ground or into a nearby river therefore polluting it.
Chemicals such as pesticides cause water pollution from storm runoff.
It can cause land pollution.
Serious Pollution
The use of pesticides is very effective in preventing and killing pests that may potentially cause damage to crops.However, almost all pesticides cause air, water or soil pollution. When the soil is contaminated, there is lower soil quality and it causes crops to be contaminated and people who consume it may get poisoned. Water pollution will destroy marine life while air pollution may spread over large areas, affecting many people.
the main use of water in agriculture is irrigation of course. it can cause pollution by carring soluts like excess nitrogen or phosphorus to underground water reserves or lakes and rivers. it can also carry dissolved pesticides and herbisides though its less likely
There are thousands of types of Pesticides, some of organic and natural sources and some synthesized chemicals like paralytics. The word pollution could be subjective, Atmospheric Pollution - Possibly through pesticides delivery system, CFCs Water System Pollution - Possibly, in the case of DDT and birds for example Soil Pollution - Possibly, in the case of chemicals that are not soluble
The chemical pesticides cause the chemical pollution for the soil, the water & the air, they cause serious health risks such as cancer, the nervous system diseases and the reproductive problems in people who exposed to the pesticides through home and garden exposure
This is only cause of water pollution. Other causes are discharge of sewage in water bodies, discharge of industrial waste, use of fertilizers and pesticides, throwing garbage and other human activities.
Water pollution is the contamination of bodies of water
They cause pollution because the chemicals put into the fertilizers run into the water; then causing water pollution.
People cause water pollution from throwing garbage and other things into the water. Also, oil and other chemicals cause pollution.
Pollutants and pathogens in air can cause respiratory ,skin and optic problems.Chemicals and pathogens in water can cause water borne disease.Chemical fertilisers and pesticides used in agriculture has harmful health problems.Sound pollution above 20,000 frequencies and high decibles from machines and traffic,loudspeakers etc. can damage the auditory system.
