Environmental Risk Assessment & Management

As part of our consulting and information services on environmental risk measures, we conduct surveys and scientifically analyze/evaluate the risks of chemical substances in the environment to ecosystem and human health (management and reduction of risks).

To provide solutions to growing concerns over the impact of harmful chemical substances to ecosystem and human health, we offer services in chemical analysis and the evaluation of environmental risks of such substances. Examples of our services include: behavior analysis of chemical and trace substances, and measurement of exposure levels using highly accurate chemical analyzer equipment; bioassays using various aquatic biota; and detailed studies on the behavior of chemicals and pollution mechanisms. We also offer comprehensive consulting services on the provision of scientific knowledge and countermeasure information that are vital for the reduction/management of environmental risks.

Behavior Analysis of Chemical and Trace Substances and Measurement of Exposure Levels

  • Environmental behavior of chemicals (dioxin as an example) Concentration distribution around the emission source
    Environmental behavior of chemicals (dioxin as an example) Concentration distribution around the emission source
  • Dioxins, PCBs
  • Persistent Organic Pollutants (POPs)
  • Agrichemical and pesticide residue in food
  • Heavy metals
  • Endocrine-disrupting compounds
  • Volatile Organic Compounds (VOCs)

Bioassays

  • Toxicity testing tanks using Japanese medaka
    Toxicity testing tanks using Japanese medaka
  • Bioassay tests based on Good Laboratory Practice (GLP) stipulated in the Law Concerning Examination and Regulation of Manufacture and Handling of Chemical Substances (test species: algae, Ceriodaphnia dubia, Japanese medaka, etc.)
  • Fish tests on endocrine-disrupting effect of chemicals
  • Toxicity testing using aquatic biota (test species: algae, Crustaceans, fish, etc)
  • Toxicity testing of effluent discharges and ambient water using aquatic biota

Detailed Studies on the Behavior of Chemicals and Pollution Mechanisms

  • Qualitative and quantitative analyses of trace chemicals (high resolution GC/MS)
    Qualitative and quantitative analyses of trace chemicals (high resolution GC/MS)
  • Analysis of harmful chemicals in bio-samples (dioxins, PCBs, POPs, etc)
  • Analysis of heavy metals in bio-samples (methyl mercury, arsenic compounds, etc)
  • Deposition dating measurements of sediment using 210Pb
  • Carbon/Nitrogen Isotopic Ratio Mass Spectroscopy (assessment of food chains, pollution sources in groundwater)
  • Inventory surveys on the sources of harmful substances

Evaluation of Environmental Risks and Proposals on Management Measures

  • Behavior analysis of chemical and trace substances, and measurements and evaluation of exposure levels
  • Hazard assessment of chemicals and effluents to ecosystems (organisms)
  • Evaluation of soil pollution by POPs and heavy metals
  • Analysis of pollution mechanisms and behavior of harmful chemicals
    ・ estimation of pollutant sources and polluted areas
    ・ analysis of exposure paths
  • Support for risk management and countermeasures
    ・ provision of scientific knowledge on risks and countermeasure technologies
