Professional Practice Webinar: Petroleum hydrocarbon risk assessment using GC data - beyond TPHCWG? (2 hours)

Recording Available Here

It is 25 years since the Total Petroleum Hydrocarbons Working Group (TPHCWG) published its five volume series of reports that have formed the basis for human health risk assessment of petroleum hydrocarbons ever since.

The TPHCWG approach is based on an empirical method of analysing hydrocarbons and splitting mixtures in to one of thirteen fractions.

New methods of analysis are now available that can give a better resolution in to the composition of hydrocarbon mixtures. However there is no guarantee that the results of these new methods of analysis are compatible with or equivalent to the ones proposed by the TPHCWG.

As part of LQM's continued commitment to raising standards among practitioners and regulators, LQM’s next Professional Practice Webinar, delivered by Paul Nathanail, will compare analyses using the TPHCWG method and current methods of analysis and explore the extent to which our human health risk assessments need to change as a result.

This two-hour webinar (GMT 1300-1500) will cover:

  • The TPHCWG method of analysing hydrocarbon mixtures
  • Present day analytical techniques
  • Impacts on allocation of fate, transport and toxicological values to TPHCWG fractions derived using present day analytical techniques
  • Consequences for risk assessors and regulators

At the end of the webinar (live version only), you will:

  • Appreciate the basis of the TPHCWG approach
  • Understand how modern analytical techniques provide greater insight into the composition of hydrocarbon mixtures
  • Appreciate the consequences on fate, transport and toxicity properties for the equivalent carbon fraction

You will be able to ask Paul questions!

This webinar is mainly relevant to regulators (including local authority staff) and consultants involved contaminated land sites where petroleum hydrocarbons are likely to be an issue.

It will be particularly relevant to anyone looking to:

  • - Carry out human health risk assessments of petroleum hydrocarbon mixtures
  • - Offer analytical services for petroleum hydrocarbons
  • - Review for regulatory purposes risk assessment reports of petroleum hydrocarbons
