In environmental chemistry, contamination is often synonymous with pollution. And environmental pollution has become one of the world's major concerns, affecting both human health and biodiversity. 

To better prevent the harmful effects of this contamination and implement effective management strategies, we need to understand its mechanisms. Our emergency spill response professionals explain.

 

How do you define contamination?

Contamination is the introduction of undesirable or hazardous substances into a natural or controlled environment, either where they don’t belong or in quantities that exceed levels that are considered safe. 

Contamination can be chemical, biological or physical, and often involves risks to human health, ecosystems or infrastructure. The types of contamination vary, from chemical pollution of soil and water to the introduction of pathogenic micro-organisms into sensitive ecosystems. 

 

What is environmental pollution?

Environmental pollution is the contamination of air, water and soil by harmful substances, mainly as a result of human activities such as industry, agriculture and transport.

Pollution is closely linked to climate change, as many pollutants, such as carbon dioxide and methane, are greenhouse gases that contribute to global warming.

Global warming disrupts natural habitats, leading to species extinction, coral bleaching, rising sea levels, and an increase in the frequency and severity of extreme weather events. 

For human populations, these changes translate into increased health risks, forced displacement, and significant economic impacts, particularly in vulnerable regions with fewer resources to adapt to these changes.

 

What are environmental contaminants?

 

Environmental contaminants include a wide range of substances. Among the most common are:

 

• Heavy metals: lead, mercury, arsenic, which can come from mining, coal combustion and other industries

 

• Persistent organic pollutants (POPs): such as Polychlorinated Biphenyls (PCBs) and dioxins, which are extremely stable and can persist in the environment for decades

 

• Pesticides and herbicides: used in agriculture, they can contaminate soil and groundwater

 

• Microplastics: plastic particles that decompose slowly and contaminate oceans, rivers and soils.

 

• Fuels: petrol, diesel, fuel oil, jet fuels;

 

• Lubricating oils : engine oil and hydraulic oil.
