Learn about Environmental Chemistry

    Chemicals are an essential part of our environment -- everything on the earth interacts with them. In this course, you'll study types of chemicals used in the environment as part of agriculture, horticulture, land management, and more. You'll learn about toxicity, necessary changes in use, and why eco-friendly products and sustainable production is increasingly important.

    Better management of our environment must begin with understanding of the changes caused by humans in our quest for industrialisation and higher production. In this course you will:

    • learn how chemicals contaminate the environment
    • study chemicals used, and the ways in which they can change the environment
    • discuss the impact chemicals can have upon changing the ecosystem and how all living things can be affected.

    This is a course not only for scientists, but also managers and users of the environment, including:

    • Environmental Managers and Assessors
    • Resource Managers
    • Manufacturers and suppliers of chemical products, such as paints and fuels
    • Factory managers, automotive managers, mechanics or anyone else working with machinery.
    • Town planners, architects, engineers, builders, landscapers

    Aims

    • Describe the nature, importance and scope of environmental chemistry and advance an understanding of basic chemistry including atoms and their components, elements, compounds and chemical reactions.
    • Outline different types of air pollutants and their causes and describe appropriate responses to contain, reduce. eliminate or otherwise deal with such problems.
    • Distinguish between various water pollutants and discuss appropriate alternative responses to contain, reduce. eliminate or otherwise respond to such problems.
    • Describe soil pollutants and compare appropriate alternative responses to contain, reduce. eliminate or otherwise respond to such problems.
    • Explain a range of ways that better management of environmental chemicals can contribute toward improved human health.
    • Explain different techniques that can be utilised for sampling and testing chemicals in the environment.
    • Explain the two broad goals of green chemistry and describe examples of green chemistry used in homes, vehicles; industry and the environment.

    This course explores this important and rapidly expanding field of Environmental Chemistry. 

    Environmental chemistry affects the world in diverse ways (both beneficial and detrimental) at scales ranging from global to microscopic.  Global examples include climate change and global warming occurring mostly due to changes in the chemical composition of atmospheric gases (greenhouse gases) largely caused by humans. Global warming is the long-term trend of a rising average global  temperatures, whereas climate change is a broader term referring to changes mostly brought about by global warming such as extreme rainfall events, increased prevalence of drought, heat waves and so on.

    At a microscopic scale, chemicals are used to control or prevent outbreaks of diseases caused by microorganisms in crops. This includes fungal diseases such as mildews, rots and wilts which may be treated using chemicals called fungicides. These fungicides may contain inorganic copper or sulphur compounds; synthetic organic compounds (such as dithiocarbamates) as well as ‘natural’ compounds such as clay. The fungicides have a beneficial effect in that they increase food production for an ever expanding population. However, some of these fungicides also have effects on the environment at a much larger scale than the intended microscopic one, due to their persistence in the environment (i.e. they do not break down with time and can accumulate). They can be toxic to soil organisms such as earthworms and to aquatic organisms such as fish or even to humans. Thus, chemicals have many interacting influences on the environment at many different scales.

    Chemicals have also had many beneficial effects on the world in which we live. For example, water has been made safe to drink by treatment with chlorine. This is called ‘disinfection’.  Chlorine kills many water-borne pathogens and has no doubt saved millions of lives from devastating infections such as cholera, typhoid and salmonella. On the negative side, it is now known that when chlorine is added to water, it mixes with organic products in the water to form toxic by-products called trihalomethanes, which can cause cancer. Safer ways to disinfect water are therefore being explored such as ozonation.
