What is a Pollutant

Pollutants are the elements, molecules, and particles that contribute to pollution; when exposed to these materials, life can be harmed, and the effects on humans and plants are well known. Pollutants can enter the environment in a variety of ways, both naturally and by humans. What pollutants do once they are released into the atmosphere, soil, or water supply depends on the type of pollutant, but it is useful to categorise them as follows: Primary pollutants are those that are directly emitted into the environment, whereas secondary pollutants are those that are formed from primary pollutants and external factors. Many pollutants are introduced into the environment in a variety of ways, have varying and sometimes unique health effects, and are found in varying amounts. 

What is a pollutant?

The introduction of harmful materials also into the environment is referred to as the pollution and these substances are referred to as pollutants. They can be caused by human activity, such as trash, or by natural processes, such as volcanic ash. Pollutants have a negative impact on the quality of water and air and land. Pollution is a worldwide issue. Pollution is carried out by air and water into the ocean currents and migrating fish. Pollution is just one of the many things that are wreaking havoc on our planet, which was once greener and healthier than it is now. Pollution is a hazardous phenomenon that contributes to a variety of health problems.

The Pollutants come in a variety of the forms and including:

• Nitrogen oxides (NOx)

• Sulfur oxides (SOx)

• Particulate matter (PM)

• Ground level ozone (O3)

• Volatile organic compounds (VOCs)

• Mercury (Hg)

• Peroxyacyl nitrates (PANs)

Types of pollutants

Pollution is defined simply as the contamination of the physical and biological constituents of the earth’s atmosphere. It has a significant impact on both human life and the natural environment. It degrades our natural resources, affecting everything from the water we drink to the air we breathe. You must include the following four types of pollutants:

• Air Pollution: Air pollution is the contamination of air in the atmosphere caused by the introduction of harmful or excessive quantities of substances such as smoke and harmful gases from industries, CFCs and oxides produced by automobiles, the combustion of solid wastes, and so on.

• Water Pollution: Water pollution is the contamination of natural water resources as a result of the addition of harmful chemical, biological, or physical materials, such as industrial wastes, oil spills, domestic and farm wastes and the pesticides and the mining and agricultural wastes, to the water resource, rendering it unusable.

• Soil Pollution: Land/Soil Pollution occurs as a result of the deterioration of the earth’s surface caused by various commercial, industrial, agricultural, and domestic activities. Mining, deforestation, dumping of e-waste and other industrial wastes, and the use of harmful chemicals such as insecticides and pesticides are all causes of soil pollution.

• Noise Pollution: Noise pollution is caused by excessive noise produced by machines, loudspeakers, microphones, loud music, noise from industries, construction and civil engineering works, and so on.

Pollutants and Pollution

A pollutant is a dangerous substance that is released into the environment. It can be released in a variety of ways and forms, such as toxic substances released into the land or water, carbon particles in smoke, or simply loud noises. A pollutant is a substance that disrupts the natural order of the environment. Pollution is defined as the release of such pollutants into the environment.

Preventing the harmful effects of environmental pollutants on human health

THL investigates the amount and routes by which the Finnish population is exposed to environmental pollutants, as well as the health risks associated with that exposure.

Our research focuses on compounds that are toxic or harmful to humans and are either persistent and bioaccumulative in the environment or to which humans are constantly exposed. These pollutants, which include dioxins and PCBs, brominated flame retardants, chlorinated pesticides, fluorinated compounds, bisphenol A, parabens, phthalates, and organic tin compounds, pose the greatest risk to human health. New chemicals are constantly being developed and introduced into the market, and our goal is to identify and mitigate any potential health risks.

We analyse the levels of environmental pollutants in humans, as well as food, animal feed, and environmental samples, at THL’s Laboratory of Chemistry. Our analytical services are available for collaborative research projects as well as external clients, depending on the analysis.
