Webinar Recording: Petroleum hydrocarbon risk assessment using GC data - beyond TPHCWG?

Only £60 (excl VAT) with online card payment discount.

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.

This ~90min recording is of a Professional Practice Webinar originally delivered on the 1st May 2019  (Note: only access to the recording will be provided. The original handouts are not included and the recording does not include the Q&A session at the end of the webinar). The webinar was delivered by Paul Nathanail and compares analyses using the TPHCWG method with current methods of analysis and explores the extent to which our human health risk assessments need to change as a result.

Prices and discounts: Prices exclude VAT.  Please note purchase is via online card payment only - a 20% discount will automatically be applied.

Invoice purchases will be declined

  • Content
  • Citation

The webinar covered:

  • 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, 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

Recent feedback:

"Very clear on explaining all aspects" (Laboratory Chemist)

"Thought provoking and relevant" (Consultant)

"Good description of hydrocarbons and their makeup" (Consultant)
