Demonstrating the safe use of chemical mixtures remains a critical challenge in toxicological science. In recent years, studies have suggested that chemicals can exhibit dose additivity—causing a combined effect—even when each chemical individually is below its effect threshold. This project...
An independent regulatory organization responsible for oversight of Alberta’s safety codes system sought to strengthen its capacity for risk-based decision-making. The organization aimed to ensure that regulatory actions—particularly in the area of petroleum storage tanks—were guided by clear, evidence-based prioritization...
Health Canada sought to enhance its Quantitative Microbial Risk Assessment (QMRA) tool, originally developed over 15 years ago for stakeholders responsible for drinking water systems. With advancements in probabilistic modeling and microbial risk assessment, the client required updates to reflect...
In response to increasing public concern about the historical use of McIntyre Powder—an aluminum-based substance once administered to miners in Ontario to prevent silicosis—the client sought expert guidance on managing risk communication related to potential health implications. Widespread media coverage...
To support public communication around emerging drinking water concerns, RSI was engaged to develop accessible, scientifically grounded materials on lithium exposure and its potential health effects. The work focused on equipping stakeholders with clear, credible information that could inform both...
A comprehensive systematic review was undertaken to assess experimental evidence regarding the potential health risks associated with artificial sweeteners, specifically focusing on cancer and pre-term delivery. The client sought a rigorous analysis of both in vivo and in vitro experimental...
The Alliance of Blood Operators (ABO) sought to move its members toward a consistent, transparent approach to risk-based decision-making. Having worked through the development of a framework, the organization now wanted formal adoption, external validation, and practical application to real-world...
In the mid-1990s the International Organization for Migration (IOM) faced one of the most pivotal moments in its history. Though it counted 76 member states, it remained outside the United Nations system, and its work was increasingly perceived to overlap...
To support the refinement and implementation of its ecological risk guidance, a federal department responsible for marine conservation engaged expert assistance in risk communication. The primary objective was to ensure that the national guidance for ecological risk assessment—developed as part...
To support national public health goals, RSI was tasked with developing a quantitative microbiological risk assessment (QMRA) model to estimate the human health risks associated with the consumption of chicken in New Zealand. The core objective was to quantify the...
To support regulatory decision-making, a comprehensive risk assessment was conducted to evaluate how varying lethality performance standards would impact the public health burden of salmonellosis associated with Ready-to-Eat (RTE) meat and poultry products. The primary objective was to quantify the...
To enhance the methodological rigour of its scientific assessments, EFSA sought to develop a standardised framework for problem formulation (PF) within its non-application scientific assessment protocols. The goal was to support the planning phase of these assessments by establishing a...
To support decision-making around modifications to opioid agonist treatment delivery, a detailed risk assessment was requested to evaluate the integration of secure dispensing devices for direct patient access to hydromorphone. Building on a previously conducted preliminary assessment, the work required...
To support its Standards to Support Resilient Infrastructure Program, the Standards Council of Canada (SCC) launched a national consultation campaign to identify and prioritize climate-related standardization needs. SCC required a flexible risk prioritization framework to evaluate the relative urgency and...
Health Canada requested an external review following significant public criticism of its handling of a pharmaceutical recall. The case involved a contraceptive drug that was withdrawn due to packaging errors, and the department faced questions about whether it had acted...
An international airport authority sought a comprehensive assessment of passenger and vehicle traffic flow after receiving complaints of confusion and safety concerns. Reports indicated that passengers were struggling to interpret signage, often stopping too long to process graphics, which caused...
To support the quality and defensibility of regulatory decision-making under the Canadian Environmental Protection Act, 1999 (CEPA), Health Canada engaged Risk Sciences International to coordinate an independent external peer review of the Draft Screening Assessment Report (DSAR) for Selected C3-C5...
Establishing science-based drinking water guidelines for manganese requires integrating diverse regulatory approaches, emerging modeling tools, and evolving toxicological evidence. The client commissioned this project to systematically assess existing manganese drinking water guidelines and the scientific foundations upon which they are...
Government authorities faced recurring challenges in communicating health risks from smoke caused by both wildfires and residential burning. While these events were becoming more frequent and more severe, the public health messages often failed to resonate with affected communities or...
To support the Chemicals Management Plan under the Canadian Environmental Protection Act (CEPA), Health Canada sought expert peer consultation for a draft screening assessment report (DSAR) evaluating 47 inorganic substances identified as priorities. The client required independent scientific and technical...
In support of ongoing efforts to modernize Canada's food inspection system, a request was issued for scientific and analytical expertise to enhance two critical risk-based decision tools: the Establishment-based Risk Assessment (ERA) and Importer Risk Assessment (IRA) models. These models...
To support more consistent and quantitative assessments of new micro-organisms under the Canadian Environmental Protection Act, Health Canada's New Substances Program (NSP) sought to refine the tools and processes within its Microbial Risk Assessment Framework (MRAF). The NSP had previously...
Authorities in Vietnam sought targeted expertise to strengthen the country’s ability to detect, assess, and respond to food safety threats. This initiative had two linked objectives: building a comprehensive, transparent, and reliable national food safety information system, and enhancing risk...
The client sought to improve understanding of uncertainties surrounding the application of mixture assessment factors (MAFs) for aquatic receptors, specifically those estimated using the KEMI methodology. While the KEMI MAF approach is considered technically robust, its assumptions—particularly about chemical-specific controls,...
UN-Habitat sought to establish a new global platform to bring coherence to international dialogue on sustainable urbanization. At the outset, this initiative had no name, no identity, and no governing structure, only the recognition that cities faced pressing challenges requiring...
