What biological factors pollute the soil?

Biological soil contaminants include pathogens, eggs and larvae of worms that are parasitic in humans and animals. Their contamination of the soil is the result of the unsanitary state of the collection and storage sites for household waste and the spread of sewage in areas reserved for individual gardens and vegetable gardens. Having passed a certain stage of development in the soil, these pollutants fall on human hands and food, are carried by insects, rise into the air with dust, penetrate into living organisms and cause various diseases.
