Marine Environments

Marine Environments


We have a long history of working with industry and authorities to ensure the security and purity of our marine and estuarine environments. We work with the mining and resources sector, maritime industry, harbour authorities and environmental consultants to provide diverse analyses to better profile and manage long-term environmental impacts and associated risks.

Our marine environment testing and analysis services include:

  • Cost-effective, unique and reliable ‘on-stream’ seawater and saline water analysis, particularly useful for monitoring dredging activities
  • Total recoverable hydrocarbons in soil and water, with low detection limits where achievable
  • Total petroleum hydrocarbons in biota, water and hydrocarbon products, with low detection limits where achievable
  • Polycyclic aromatic hydrocarbons (PAHs) in water, soil, biota and hydrocarbons

Polycyclic aromatic hydrocarbons (PAHs)

ChemCentre is a recognised leader in the detection of trace amounts of polycyclic aromatic hydrocarbons (PAHs) in seawater, sediments and marine life. Our tests help industry clients and regulators to determine when, from where and how much PAHs are entering the marine environment.

Polycyclic aromatic hydrocarbons (PAHs) are a group of more than a hundred different chemicals produced when fuels, wood and other organic materials such as tobacco are incompletely burnt. While PAHs occur naturally at low levels in the environment and as a result of natural events (e.g. bushfires), a majority of PAH sources are man-made.

PAHs find their way into the marine environment mainly through oil spills, discharges from ships and offshore oil and gas exploration and drilling. High levels of, or prolonged contamination by, PAHs in marine environments can have detrimental impacts on industries, public health and ecology.

ChemCentre has implemented testing programs for areas including off the northwest shelf of Western Australia (WA) where oil and gas drilling is common, as well as port areas around WA. Our techniques help to establish baseline levels of PAHs in marine environments, which in combine with monitoring and incident response, helps to develop an appropriate response and minimise any detrimental effects.

ChemCentre is the only Australian laboratory able to provide industry and regulatory clients with timely, accurate testing for very low levels of PAHs in marine sediments.
