Come see us at this years SETAC conference!
Date: 20-24 October 2024
Location: Fort Worth Convention Center
Our teams work through comprehensive risk management solutions, leveraging our global network to monitor changing regulations while defining risk management strategies to assess and mitigate liabilities, including product stewardship and supply chain requirements to design personalized and inventive comprehensive low-cost solutions. We recognize our clients’ need to focus on their core operations and business while balancing the risk of emerging contaminants.
At the SETAC North America 45th Annual Meeting, our professionals will provide informative learnings on risk assessment and PFAS to address challenges proactively and ensure a healthy community and environment for generations to come.

Given the growing body of aquatic toxicity studies in recent years, there is an opportunity to update the acute and chronic aquatic toxicity database used for Target Lipid Model (TLM) calibration/validation and re-evaluate aspects of the original model formulation. The primary focus of the new modeling work was reconsideration of octanol as the target lipid surrogate. A total of eight different partitioning models were considered. This presentation will uncover the best possible alternative approach.

This presentation is intended to provide an overview of the importance of using appropriate PFAS dermal absorption (ABSd) values and how using the range of available inputs may underestimate or overestimate actual exposure levels. Dermal exposure screening levels developed using USEPA dermal absorption assumptions listed in the Regional Screening Level chemical specific parameters table for PFAS can provide a perspective but may not be appropriate in all evaluations

A critical review evaluating Sediment Quality Guidelines (SQGs) for use in screening-level risk assessments to identify sediments that may pose a risk to the benthic community was undertaken using polycyclic aromatic hydrocarbons (PAHs). Recommendations for the use of SQGs in screening evaluations and enhancements to current approaches are discussed.

This session will present case studies of causal analysis for ecological risk assessment, site management, and natural resource damage assessments (NRDA), focusing on quantifying potential harm or injury from sediment contamination. Additional topics may include methods for deriving sediment quality criteria, interpretation of sediment quality data, improved sediment sampling collection/analysis methods, application of passive sampling, sediment contaminant modeling, and site remediation, all of which focus on obtaining a better understanding of causality.

This work will present the results of a meta-analysis of concentrations of five select PFAS (PFOA, PFOS, PFNA, PFHxS, HFPO-DA or GenX chemicals) in rainwater and surface water to quantify potential background conditions. Comparisons of relevant statistics to the April 10, 2024 U.S. EPA maximum contaminant levels (MCLs) will be completed to show whether or not these waters without a known or suspected release would exceed, and thus could by themselves show elevated background concentrations that could migrate onto a site. The implications these concentrations have on properly assessing background conditions, conducting PFAS sampling events and the evaluation of results in a contaminated site context will be included.
