Questions and Answers

What are some sources of potentially toxic materials that find their way into the world's soils?

potentially toxic industrial, domestic, and agricultural products and waste materials

What happens to organic residues in the soil?

They are broken down by soil microbes each year.

How can fertilizer and manure applications result in the contamination of ground and surface waters?

Excess quantities of nutrients in the soil can result in the contamination of ground and surface waters with nitrates and phosphates.

What is eutrophication, and how is it related to soil contamination?

Eutrophication of lakes, estuaries, and slow-moving rivers is evidence of nutrient buildups caused by excess nutrients in the soil. Signup and view all the answers

What is the significance of the soil's capacity to sorb chemicals, and what happens when these limits are exceeded?

The soil's capacity to sorb chemicals is important for environmental quality, but when these limits are exceeded, environmental quality suffers. Signup and view all the answers

Study Notes

Soil Pollution Overview

Millions of tons of potentially toxic waste enter soils annually from industrial, domestic, and agricultural sources.
Contaminants in soils participate in biological cycles, impacting all life forms.

Soil Capacity and Limits

Soils possess a vast ability to assimilate organic and inorganic chemicals.
Soil microbes decompose significant amounts of organic waste every year.
Inorganic chemicals can be tightly bound by soil minerals, aiding in detoxification.
Soil has a finite capacity for absorbing these chemicals; exceeding this limit degrades environmental quality.

Nutrient Contamination

Excess application of fertilizers and manure can lead to nutrient surpluses in soils.
This surplus can leach into groundwater and surface water, causing contamination with nitrates and phosphates.
Eutrophication, characterized by nutrient buildup, occurs in lakes, estuaries, and slow-moving rivers, leading to ecological imbalances.

Impact of Industrial Agriculture

Large-scale animal production facilities contribute significantly to soil pollution.
Such operations increase the likelihood of nutrient runoff, exacerbating water contamination issues.
