Webinars: LQM PAH Profiling Tool

LQM have launched a new quick and easy tool to assist risk assessors to determine if currently available generic assessment criteria (such as the C4SL for “Benzo[a]pyrene” and the S4UL for “Coal Tar (BaP as surrogate marker)” ), which are based on a surrogate marker approach, are applicable to the assessment of the mixtures of PAHs in soil at their sites.  Click here for further details.

We are also running a FREE webinar to explain the scientific background behind the surrogate marker approach and the assumptions it is based on, what the Tool does and how to use it.  Topics that should be covered during the webinar include:

  • What are PAHs and why are they difficult to risk assessment?
  • What is the Surrogate Marker Approach to PAH risk assessment?
  • Why are there apparently two S4ULs for benzo[a]pyrene (BaP) and when can they be used?
  • How can i decide if the surrogate Marker Approach is appropriate at my Site?
  • How do you use the LQM PAH Profile Tool and how does it help?
  • What is the differences between the free trial version and the full version, which is available for purchase?

Why attend? Local authorities should understand the basis for assessing the risks posed by PAH mixtures in soil and that the simple surrogate marker effect may not always be scientifically valid, and how to check whether the various assessment criteria are being used robustly .  Consultants should know the limitations behind the surrogate marker approach and justify its use in any reports they produce.
