Petroleum hydrocarbon risk assessment using GC data – beyond TPHCWG?

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 our continued commitment to raising standards among practitioners and regulators, LQM’s next Professional Practice Webinar, delivered by Paul Nathanail, will help you find out more about how to 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 via LQM’s upcoming Professional Practice Webinar on 1st May 2019:
