Answer 2

The use of excessive quantities of synthetic fertilizers is harmful to 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 diseases like haemoglobin disorders, Alzheimer's disease and diabetes mellitus.

If the supply of chemical fertilizers is adapted to the adsorption capacity of the soil (the soil reacts as an ion exchanger) there is no danger of pollution. However, if the supply of these fertilizers exceeds the capacity of the soil it may contaminate the groundwater and possibly the surface water (rivers lakes) with all the adverse effects we know.

Depending on the amount of fertilizer consumed, it may cause disturbances of the kidneys, lungs and liver and even cause cancer.

This is due to the toxic metals that fertilizers have. Fertilizers remove the nutrients from the soil, damaging the soil and the local environment.
