Type: Farming Chemicals

Definition:  “Agricultural chemicals” as chemical agents such as fungicides and insecticides that are used to control crop-harming organisms (e.g., fungi, nematodes, mites, insects, and rodents or viruses)

 

 

Use of these chemicals: Agricultural chemicals have an important role in land management and the production of food and fibre products, protecting plants from damage caused by insect pests, weeds or disease.In most cases, agricultural chemicals are referred to as ‘pesticides’ and include herbicides, fungicides, insecticides and pest animal baits.Many of these chemicals are hazardous and present risks to human and animal health, the environment and trade if not used correctly.

 

Contributor to which types of pollution: Land, Water, Air

 

What chemicals are used in farming: Many farmers choose to use chemicals to keep weeds and pests from destroying their crops and to add more nutrients to the soil. There are three different kinds of pesticides; herbicides, insecticides and fungicides. All three of these pesticides are used to kill different kinds of pests that can be found on a farm.

How does this contribute to pollution:

 

Land: When farmers introduce these chemicals into the soil for faster plant growth and killing pests in the soil, you introduce something to the soil that might change it. It may pollute the soil and affect the plant in a negative way by having harmful effects on the fruit of vegetable of the plant.

 

Water: Plants are constantly given water so they can grow. When you introduce a chemical to the soil or plant, the water mixes with the chemical. Then the water gets absorbed by the soil and the water goes into the ground and becomes groundwater. This groundwater may later go into a lake or another body of water and further pollute the water.

 

Air: To give this chemical to the plant or soil, sometimes farmers use gas to transfer this chemical to the plant or soil. This gas can also mix around the surrounding air and pollute the air during this process.
