The Australasian College of
Toxicology & Risk Assessment

Join the Australasian College of Toxicology & Risk Assessment (ACTRA) in a unique webinar series that commenced in June 2020! The webinar series will cover two overarching themes in relation to toxicology and risk assessment in Australia:

  1. Lessons learnt from case studies.
  2. Practical applications of theoretical concepts.

These sessions will provide you with an opportunity to gain insight from Australia’s most accomplished and experienced toxicologists and risk assessors, and more importantly encourage an open forum for questions and discussion.

Attending webinars counts towards your continuing education credit points at the rate of one point per webinar.

If you’re new to the ACTRA webinar series here is a taste of what to expect:

ACTRA is pleased to present this webinar series on “Food from contaminated environments” by Katie Richardson, starting on 5 May 2022.

Food from contaminated environments: assessment and management of risk

Where contaminants with the potential to bioaccumulate are present in the environment, there is the potential for people and/or wildlife to be exposed via pathways of food consumption. These pathways are of particular importance where contamination is present in rural areas (where significant agricultural activities may occur, and where significant ecosystems may be present), and in residential back yards (where exposure may occur to home grown produce or chicken eggs).

Undertaking risk assessment of these pathways is relatively complex, as it requires assessment of contaminant uptake and bioaccumulation processes, and/or biota analysis (which can be costly and comes with its own complexities around undertaking sufficient analysis to support all potential exposure pathways). It is also necessary to estimate food consumption rates for both human and ecological receptors to provide a meaningful estimate of risk.

This series of webinars discusses available screening tools, together with approaches for further risk assessment (supported by case study information). The series aims to provide attendees with a framework for thinking through the exposure pathways that should be considered, and a toolkit for approaching both assessment and management of human health and ecological risks for contaminants which may bioaccumulate through the food chain.

Session 1: Human Health Screening Approaches

  • Which contaminants do we consider, and who might be exposed?
  • Available Australian screening levels which incorporate a pathway of home produce consumption, including the NEPM Health Investigation Levels (HILs) and the HILs for poly-fluoroalkyl substances (PFAS).
  • Guidance on organochlorine pesticides (OCPs) and backyard chickens.
  • Extending screening approaches (e.g. for greater consumption rates, or for other pathways).

Session 2: Human Health Risk Assessment Approaches

  • Modelling uptake into fruits, vegetables, livestock and aquatic foods (with case study examples).
  • The role of biota sampling in risk assessment, including approaches for dealing with variable concentrations.
  • Risk management approaches and options.

Session 3: Ecological Risk Assessment Approaches

Following on from the first sessions (which focussed on human health) this session covers screening approaches and further risk assessment for contaminants which can bioaccumulate through the ecological food chain (with case study examples).

  • Aquatic ecosystems: screening approaches, and further assessment through modelling uptake, and measured concentrations (with case study examples).
  • Terrestrial ecosystems: screening approaches, and further assessment through modelling uptake, and measured concentrations (with case study examples).
  • Risk management approaches: considerations on when to cease assessment and move to management; management options and limitations.

About the Presenter

Katie Richardson is an ACTRA Registrant, and Senversa’s National Risk assessment practice leader. She has over 18 years of experience undertaking human health and ecological risk assessments. She started her risk assessor life in the UK modelling vapour intrusion and groundwater transport for large portfolios of petroleum filling stations, and since moving to Australia in 2008 has worked on a wide variety of contaminated land sites, including industrial and government facilities, petroleum sites, mines and linear infrastructure.

She has extensive recent experience with PFAS risk assessment and has particular expertise in the development of pragmatic assessment and management strategies. This includes work for major Defence, Airport and industry sites, including sites in remote locations and sites where complex exposure pathways (into foodstuffs and through the ecosystem) require efficient and pragmatic assessment.

Katie particularly enjoys pulling in risk assessment thinking from the earliest phases of a project to develop an efficient strategy for closing out issues. A pragmatic strategy to answer the key questions at the start can save a lot of unnecessary work.

Outside of work, Katie is a keen singer, and a member of a number of Melbourne chamber choirs. She’s sad that COVID means it’s over 2 years since she sang in a concert!
