LQM is a specialist environmental consultancy based in Nottingham (UK) with an international reputation for assessing and managing the risks posed to human health and the environment by contaminants in soil. Increasingly this is being done within a context of sustainable development and specifically sustainable brownfield regeneration.

We provide consultancy, peer review and expert witness services, contract research and training courses on all aspects of the management of land contamination to problem holders, developers and local government.

Use of Bioavailability Estimates in the UK

Using the total contaminant concentration in your risk assessments can result in additional costs (unnecessary and unsustainable remediation), development delay or blight. Understanding how to use contaminant bioavailability estimates in the UK risk assessment process is key to avoiding over-estimating risks.

LQM staff have pioneered the practical use of and been actively involved in research associated with the bioaccessibility of metals since well before the first Environment Agency oral bioaccessibility reports were published in 2002. From housing developments, riparian allotments, former gas works, borrow pits through to upland metalliferous mines LQM have successfully applied oral bioaccessibility results to the regulatory decision process, especially for Lead and Arsenic and more recently benzo(a)pyrene.  We wrote the CIEH professional practice note to regulators and incorporated site specific bioaccessibility into the SNIFFER method.

Lead, a common UK contaminant of increasing concern, provides a good example of where additional regulatory burden and unnecessary remediation is often the default position, due to inadequate understanding or over conservative risk evaluation.

Therefore, this online course explores the science underpinning bioavailability tests, tests currently available, and how careful use of contaminant bioavailability estimates within the risk assessment process can help clarify those risks, including lead.

Training is via a series of interactive presentations and exercises, delegates will receive hands on support from LQM trainers and will be able to interact with other delegates.

Key course contents will include:

  • Using bioaccessibility test results as a surrogate for bioavailability estimates
  • The science and UK regulation behind applying bioavailability in human health risk assessment
  • Good practice to apply in your human health risk assessments
  • Historical sources of lead and what does that mean for bioaccessibility
  • Risk assessment tools suitable for assessing risks to lead
  • Common misconceptions in applying bioaccessibility test results
  • Tests for plant uptake, inhalation and dermal exposure pathways
  • Bioavailability of organic contaminants

By the end of the course you should better understand:

  • How to evaluate sites using bioaccessibility data
  • The do’s and don’ts of using bioaccessibility data
  • Use of bioaccessibility data in practice on real sites (focusing on lead)
  • Potential uncertainties in estimates of bioavailability
  • Different tests available
All delegates will be issued with a Certificate of Attendance – which should be retained and used to provide evidence of CPD activity when required by employers or professional bodies.

This course is of relevance to :

  • Regulatory and local authority staff involved with contaminated land issues
  • Consultants
  • Problem holders and developers needing a more in-depth understanding of contaminated land issues
  • Anyone producing contaminated land reports
  • Anyone reviewing third party reports
