How does agrochemicals affect the environment?

While agrochemicals increase plant and animal crop production, they can also damage the environment. Excessive use of fertilizers has led to the contamination of groundwater with nitrate, a chemical compound that in large concentrations is poisonous to humans and animals.

How do pesticides and fertilizers pollute the environment?

Pesticides can move off-site to contaminate surface water and leach to groundwater. Damage to nontarget organisms and pollution to the soil and air are well documented [59]. The released pesticides into the environment and their impacts on many species have been known for a long time.

How has the use of chemicals in agriculture lead to the poor health of human beings?

Use of excessive quantity of synthetic fertilizers are harmful for human health. It is contaminating the surface water via runoffs and its consequent effects. High levels of nitrates and nitrites in chemical fertilizer may cause some disease like hemoglobin disorders, Alzheimer’s disease and diabetes mellitus.

What is the impact of agrochemicals?

Impacts on Water: Usually, make water unfit for humans and animals consumption. Diffusion of Agrochemicals in larger water bodies promotes the growth of algae which is again hazardous. Excess chemicals may lead to Eutrophication. Lead12 to water pollution thereby affecting aquatic habitats.

Why are pesticides considered pollutants?

Pesticides kill insects and pests thereby protect the crops but these pesticides remain on the crops which enter the food chain and get accumulated in the organisms at the top most tropic level that causes diseases. When these are washed away by rain river water, it also causes pollution.

What are the harmful effects of using pesticides?

Examples of acute health effects include stinging eyes, rashes, blisters, blindness, nausea, dizziness, diarrhea and death. Examples of known chronic effects are cancers, birth defects, reproductive harm, immunotoxicity, neurological and developmental toxicity, and disruption of the endocrine system.

Why are fertilizers and pesticides considered as environmental hazard?

Impact on environment Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.

What are the harmful effects of using chemical fertilizers?

Harmful Effects of Chemical Fertilizers

• Waterway Pollution. Water polluted by chemical fertilizers.
• Chemical Burn. Chemical leaf scorch can cause the plant to wither and die.
• Increased Air Pollution. An ice berg melting due to increased water surface temperature.
• Soil Acidification.
• Mineral Depletion.

Do you think that the chemical based fertilizers and pesticides have harmful effects on our health?

Pesticides have been reported to cause several adverse health effects which depend on the extent and duration of exposure. Health effects of pesticides range from mild allergies, rashes, breathing difficulties, neurotoxicity and reproductive abnormalities to deadly chronic diseases like cancer.

What are the effects of agrochemicals on the environment?

Agrochemicals in water diffuse with larger water bodies to promote the growth of algae – which can cause organisms such as fish to die. (This phenomenon is widely called Fish kills) Excess chemicals lead to eutrophication. Leads to water pollution.

Are agrochemicals harmful to wildlife?

Though there are random usages of agrochemicals, and usage levels are getting higher, the wildlife gets more threatened by the negative effects of using these chemicals. The toxicities and impact of agrochemicals causing death of animals can be easily identified and influenced.

What are agrochemicals and what are they used for?

In short, they are agricultural chemicals. Although initially used to improve crop production, overuse of chemicals has now started affecting the environment. Apart from the obvious effects on crops and the food chain, agrochemicals have a wide area of application.

Are farmers aware of agrochemicals residues and their behaviors regarding application?

Investigating farmers’ awareness of agrochemicals residues and their behaviors regarding application is important in order to reduce human factors that negatively affect agricultural safety.
