What is Pollution?
“Pollution is the introduction of substances (or energy) that cause adverse changes in the environment and living entities .”
Pollution need not always be caused by chemical substances such as particulates (like smoke and dust). Forms of energy such as sound, heat or light can also cause pollution. These substances that cause pollution are called pollutants.
Pollution, even in minuscule amounts, impacts the ecological balance. Pollutants can make its way up the food chain and eventually find its way inside the human body. Read on to explore the types of pollution and their implications.
Types of Pollution
As stated before, there are different types of pollution, which are either caused by natural events (like forest fires) or by man-made activities (like cars, factories, nuclear wastes, etc.) These are further classified into the following types of pollution:
22,386
There are various types of pollution chiefly arising as a result of anthropogenic causes. Also contributing to pollution is globalisation, where humanity’s constant need for natural resources has slowly started to change the face of the earth.
Though the quality of living has drastically improved, other new issues have risen that gradually impact human health and the environment. In this article, we shall explore the meaning, causes and types of pollution. Also, we shall analyse the repercussions of pollution on human health and the environment.
Types of Pollution
Air pollution refers to the release of harmful contaminants (chemicals, toxic gases, particulates, biological molecules, etc.) into the earth’s atmosphere. These contaminants are quite detrimental, and in some cases, pose serious health issues. Some causes that contribute to air pollution are:Burning fossil fuels
Mining operations
Exhaust gases from industries and factories
The effects of air pollution vary based on pollutant. But generally, the impact of air pollution range from:
Increased risk of respiratory illness and cardiovascular problems
Increased risk of skin diseases
May increase the risk of cancer
Global warming
Acid rain
Ozone depletion
Hazards to wildlife
Among the other types of pollution, air pollution is theorized to have a planet-wide implication.
Water pollution is said to occur when toxic pollutants and particulate matter are introduced into water bodies such as lakes, rivers and seas. These contaminants are generally introduced by human activities like improper sewage treatment and oil spills. However, even natural processes such as eutrophication can cause water pollution.
Other significant causes of water pollution include:
Dumping solid wastes in water bodies
Disposing untreated industrial sewage into water bodies
Human and animal wastes
Agricultural runoff containing pesticides and fertilisers
The effects of water pollution are very pronounced in our environment. Furthermore, toxic chemicals can bioaccumulate in living beings, and these chemicals can travel their way up the food chain, ultimately reaching humans.
Among the other types of pollution, water pollution has a more disastrous consequences on humans. For instance, in 1932, a grave case of water pollution incapacitated the inhabitants of an entire city in Japan with neurological diseases and mental illness for many decades. However, the immediate cause not apparent but was eventually attributed to acute mercury poisoning. Methylmercury was dumped into the surrounding bay and had ultimately bioaccumulated inside the fish. The local population then consumed these fish, and this resulted in the manifestation of ill-effects and neurological diseases.Other consequences of water pollution include:
Disruption of the ecosystem
Threats to marine life
Increased risk of water-borne diseases
Increases toxic chemicals (such as mercury) in water bodies
EutrophicationSoil pollution, also called soil contamination, refers to the degradation of land due to the presence of chemicals or other man-made substances in the soil.
