Pollution is any substance or form of energy that can cause harm or imbalance (irreversible or not) in an ecosystem, in the physical environment or in a livingbeing. It is always a negative alteration of the natural state of the environment, and therefore is generated as a result of human activity.
For there to be contamination, the contaminant should be inrelative amounts sufficient to cause this imbalance. The relative amount can be expressed as the mass of the substance introduced in relation to the mass or volume of the receiving of it. This ratio iscalled concentration.
The pollutants are related to population growth and consumption (fossil fuels, the generation of waste, industrial waste, etc...), and that increasing them, the pollution theycause is greater.
For consistency, the pollutants are classified as solids, liquids and gases. Discard those generated by natural processes, since, by definition, do not pollute.
The agents consist ofsolid waste in its various presentations. Cause pollution of soil, air and water. Soil because it produces harmful microorganisms and animals, the air because it produces bad odors and toxic gases,and water because the dirty and not usable.
Liquid agents include sewage, industrial waste, and spills of petroleum fuels, which harm the water mainly from rivers, lakes, seas and oceans, and therebycause the death of various species.
Gaseous agents include oil combustion (nitrogen oxide and sulfur) and the burning of fuels such as gasoline (which releases carbon monoxide), garbage and debrisfrom plants and animals.
All pollutants from a particular source and can cause respiratory and digestive diseases. It is necessary for human society to become aware of the problem.
It's called airpollution or environmental contamination present in the environment of any agent (physical, chemical or biological) or a combination of several drugs in places, forms and concentrations as they are or...
