Ecological Risk Assessment

Risk Assessment for Former Creosote-Based Wood Treatment Facility, North Carolina Evaluated ecological risks to representative mammalian, avian, and invertebrate receptors by modeling exposure concentrations in diet items using bioaccumulation uptake equations, assisting in the calculation of surface-weighted average concentrations, and developing receptor-specific remediation goals.
Risk Assessments for Former Wood Treatment Facility, Mississippi Assisted with the human health and ecological risk assessments for a former wood treatment facility. Work includes chemical screening, developing exposure parameters, compiling toxicity criteria, calculating receptor risks, and using in- house R statistical programming upper confidence limit (UCL) and risk assessment calculation tools. Chemicals of concern include PAHs and dioxins/furans.
Assessment of Pesticide Use, Tule Lake and Lower Klamath National Wildlife Refuges, California Contributed to a multiyear project with federal agencies in developing pesticide use profiles for several active ingredients. Evaluating the potential toxicological effects of pesticide use on wildlife resources using publicly available data from EPA ecological risk assessments, USDA pesticide use risk assessments, the Pesticide Action Network (PAN) Pesticide Database, the Office of Pesticide Programs (OPP) Pesticide Ecotoxicity Database, CompTox, and ECOTOX.

Human Health Risk Assessment

Evaluation of Brass Rod Alloy Products for Proposition 65 Compliance, California Supported assessment of consumer and worker exposures to a number of brass rod alloy–based plumbing fittings containing lead, a California Proposition 65–listed chemical. Researched exposure models and parameter values for chemical intakes resulting from drinking water ingestion and hand-to-mouth transfer exposures.
Frenchtown Mill, Missoula, Montana Assisted with ecological and human health risk assessments by identifying data gaps relevant to the remedial investigation, risk assessments, and feasibility studies.
Human Health Risk Assessment for Extended Floodplain, New York Participated in human health risk assessment for an extended river floodplain area in New York State where PCBs are the chemical of concern. Completed review of current and anticipated future use for study area parcels.
1,2,3-Trichloropropane (TCP) Toxicity Assessment Supported a critical assessment of EPA’s toxicological review for 1,2,3-TCP. Compiled available maximum contaminant levels and risk-based screening levels for 1,2,3-TCP. Conducted reviews of 1,2,3-TCP toxicity literature.
Technical Review of Vanadium Public Health Goal Reviewed EPA’s public health goal for vanadium. Evaluated available noncancer toxicity criteria and the underlying toxicity data. Assessed the relative contributions from various media to evaluate the use of a default relative source contribution term.

Product Stewardship

Safety Assessments for Personal Care Product Ingredients, U.S. Compiled and reviewed data on the toxicity of personal care product ingredients from publicly available data sources (e.g., European Chemicals Agency [ECHA], Cosmetic Ingredient Review). Incorporated information from potential exposure scenarios to create safety assessments.
Environmental Risk Assessment of a Novel Pharmaceutical, U.S. Assisted in the evaluation of a pharmaceutical with a novel mode of action for its new drug application for the FDA. Included conducting a weight-of-evidence assessment using read-across compounds, assessing the aquatic environmental risk, and calculating expected environmental concentrations.
Improving the Sustainability Profile of a Portfolio of Consumer Products, U.S. Assessed the biodegradability and ecotoxicity of chemical ingredients of interest to the client using the ECHA, ECOTOX, National Industrial Chemicals Notification and Assessment Scheme, and CompTox databases. Grouped ingredients according to chemical structure and determined surrogates appropriate for read across. In cases where data were lacking, used ECOSAR and EPISUITE to model data.
Analysis of Monitoring Data of Fragrance Material in Surface Waters, U.S. Evaluated the monitoring data available for the fragrance material 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran (HHCB) by gathering surface water and sediment data from the National Water Information System. Compared data from 2015–2021 to literature data to determine whether environmental concentrations had changed in recent years.

Litigation Support

Human Health Risk Assessment Regarding PCBs, Multiple U.S. Locations Providing technical support for data analysis of PCB concentrations in surface water, sediment, and fish, including calculation of UCLs using EPA’s ProUCL software. Researching exposure parameter values associated with fish consumption, recreational activities, and demographics. Conducting quality assurance review of probabilistic human health risk assessment.
Exposure Assessment Regarding PCBs, U.S. Assisting with data management, analysis, and visualization regarding potential exposure to PCBs via inhalation of indoor air. Supporting preparation of expert reports.
Exposure Analysis based on Fate and Transport of Landfill Gas, Louisiana Analyzing and visualizing frequency, duration, and concentration data related to potential exposure of communities to gas emitted from a nearby landfill. Performing various quality assurance tasks in support of expert report.

Site Assessment

PFAS Remedial Investigation, New Jersey Collect surface water, sediment, and porewater samples in support of per- and polyfluoroalkyl substances (PFAS) investigations.

PFAS

Regulatory Toxicology Evaluations for PFAS, Worldwide Reviewed the scientific basis of proposed rulemakings at the state, federal, and international levels.
Integral’s Monthly PFAS Alerts Summarize scientific publications regarding PFAS remediation and treatment, toxicology, monitoring, and environmental and human risk.

Contaminated Sediments

Portland Harbor Superfund Site, Portland, Oregon Support remedial design by managing and summarizing sediment data and groundwater data.

Data Analysis

R Statistical Programming Experience with R programming language to analyze and visualize data in support of litigation, ecological risk assessments, human health risk assessments, and other client projects.
