Biological pollution is caused by organisms with a specific life cycle, in this process, in order to carry out this cycle, they live in an environment that can reduce the quality of air, water, soil and food, and is a great danger to living organisms. It causes infectious or parasitic diseases. therefore, when these types of organisms infect the above environment, biological contamination occurs, which damages many organisms that use these resources for their life cycles.Bio-pollution or bio-pollution (consequence or bio-pollution) is the effect of human actions on the quality of the aquatic and Land Environment. In particular, Bio-pollution is the entry of non-native and invasive species. When Bio-pollution enters an aquatic environment, it causes water pollution.Soil pollution is the part of the Earth's erosion that causes the presence of xenobiotic chemicals or other people's changes in the soil. The main reasons for soil pollution are industrial activities, agricultural chemicals and wastewater disposal. Multi-ring aromatic hydrocarbons such as naphthalene, petroleum hydrocarbons, solvents, heavy metals such as lead and Mercury, and herbicides and pesticides are the most important soil-polluting chemicals. Air pollution occurs when large volumes of harmful particles or substances such as gases, particles, and biomolecules enter the Earth's atmosphere. Air pollution is a mixture of suspended particles and gases whose concentration has reached a harmful range for humans that can be both inside and outside the building. Indoor air pollution is caused by burning solid fuel sources - such as firewood, agricultural waste, and dung - for cooking and heating. Burning such fuels, especially in poor households, can lead to air pollution and, as a result, respiratory diseases that can cause premature death.
