Environmental Chemist

What is an environmental chemist? Environmental chemists work to improve environmental health and safety using their knowledge of the chemical properties of substances. They study the formation of chemicals, how chemicals interact with the environment and what effects they have. They also apply chemical theory to calculate the impact of human activity on the environment.

At a Glance

Imagine you are standing on the edge of a small stream trickling through your state-of-the-art laboratory. You are an environmental chemist working for a large manufacturing firm and this stream has been built to replicate a typical aquatic ecosystem.

Unlike natural streams, this one is laced with monitoring equipment that allows you to measure and record its chemical, physical, and biological properties and how they change through the course of an experiment. This stream is one of several ways you research and test new products to determine their environmental impact before they are put on the market.

As an environmental chemist, you test new products developed by the manufacturing company to ensure they do not pose a threat to the environment.

Your latest project is testing a new liquid sealant that the company plans to apply to its consumer products to prevent premature wear and tear.

Your lab has been given the task of determining if it is safe to use the liquid sealant based on how it affects and persists in the environment. Using sophisticated instruments such as chromatographs and the stream replicate, you will analyze and test the sealant to answer a number of environmental questions.

You need to know what happens when this product is released into the environment: does it break down into other products or stay intact?

You will test the effect this chemical has on waterways and determine what happens when it is discharged into the river, how it affects fish and aquatic plants, and how it affects wildlife that drinks from the river. Is there a risk of bioaccumulation in the food chain? Is this chemical removed from drinking water when it goes through the treatment facility? What about wastewater treatment processes?

You and your lab must find answers to all these questions before you sign off on the safety of this sealant and approve it for use on consumer products.

Education and Skills

If you are a high school student considering a career as an environmental chemist, you should have strong marks or an interest in:

  • Chemistry
  • Mathematics
  • Biology
  • Physics

In most cases, the minimum education requirement to work as an environmental chemist is a university undergraduate degree, though the majority of positions are in research and require graduate studies. If you are a post-secondary student considering a career as an environmental chemist, the following programs are most applicable:

  • Chemistry
  • Environmental Science
  • Chemical Engineering

Certification is not mandatory for Environmental Chemists, but many practitioners choose to belong to professional associations such as their provincial association for professional chemists or to become a Certified Environmental Professional (EP).

Benoît Desroches

Benoît Desroches was always interested in chemical phenomena and always appreciated nature. Today he has the good fortune to be able to combine his interest in chemistry with a mission to protect the environment from toxic and dangerous chemicals. Benoît works in the laboratory at Stablex Canada, where his job is to verify the chemical composition of industrial residues brought into the lab.

When necessary, Benoît puts the residues through a treatment program that neutralizes them. Benoît also determines the appropriate disposal method for the chemical residues, which means he takes responsibility for making sure environmental and safety regulations are followed. Benoît studied for his bachelor of science in chemistry at the Université de Montréal. He got his current permanent position at Stablex after completing a summer work term there. What does he enjoy about his job? "The challenge of working safely in spite of the risks the chemicals present."

Your Impact

Environmental chemists help to promote environmental sustainability, conservation, and protection, and they contribute to the formation of regulations that protect the environment. They often coordinate with others working in geochemistry, oceanography, limnology, hydrogeology, and toxicology.

Environmental chemists may find employment with the provincial or federal government, land management and regulatory agencies, or they may conduct research and teach at academic institutions.

Environmental chemists contribute greatly towards environmental compliance. As an environmental chemist, you act as an advisor on the potential outcomes of contaminants in soil and groundwater, assess long-term risks to ecological and human health, and develop corrective strategies to resolve problems created by contaminated run-off, classify soils as hazardous waste, and manage their disposal during onsite remediation.

Environmental chemists look at the effects of pollutants and aim to reduce the level of contamination.  By studying the behaviour of the environment and how different pollutants react and interact with the environment, they can assess how they may affect human health and the economy.

There are many chemicals that interact in the environment and it can be difficult to know where they originated. Chemicals are introduced into the environment from various sources, including pesticides, oil spills, and harmful emissions from factories and vehicles. The research compiled by environmental chemists looks into the effects of chemical waste on wildlife, organisms, and human health when it is not properly disposed of and develops the tools and techniques needs to reduce the negative effects.

Occupational Classification

Individuals working as environmental chemists may be classified as:

NOC Code: 2112- Chemists

NOC Code: 2263- Inspectors in Public and Environmental Health and Occupational Health and Safety

NOC Code: 2134- Chemical Engineer

What is a NOC Code?

The National Occupation Classification (NOC) provides a standardized language for describing the work performed by Canadians in the labour market. It gives statisticians, labour market analysts, career counsellors, employers and individual job seekers a consistent way to collect data, describe and understand the nature of work within different occupations.

The NOC is developed and updated in partnership with Statistics Canada to coincide with the 5- year census cycles. It is based on in-depth occupational research and consultations conducted across Canada, to reflect changes in the Canadian labour market.
