Biochemists study the chemistry of the reproduction, growth, heredity, respiration, etc. of living organisms. In the environment sector, biochemists conduct field studies and laboratory research to characterize chemicals present in our environment and their risks for human and animal health. Their expertise is needed to devise new methods for treating wastewater and hazardous waste. Giving advice regarding the protection of aquatic habitats from the release of industrial effluents in our rivers and lakes is also part of their work. They also research new, more environment-friendly, pesticides and fertilizers.
Microbiologists study micro-organisms and how they affect human, animal and plant health.
Part of their job is to collect water samples, sludges and sewage and examine the micro-organisms they contain through microscopes. They will identify the types and quantity of microorganisms, looking for any harmful effects they may cause. The work done by microbiologists has resulted in many innovations in environmental clean-up work. For example, they have been using naturally occurring microbes, or genetically selected ones, to detoxify underground sources of water. Biochemists and microbiologists act as microscopic detectives, collecting and analyzing information to develop scientific solutions to health threats or to create new processes to deal with waste or contamination.
