Successful chemical assessment programs allow the science to speak for itself

Everyone who is committed to producing better and timely chemical assessments would agree objectivity is one of the hallmarks of a sound assessment program.

Putting all the pieces together: ACC helps improve chemical risk assessments

Most would agree that credible, science-based assessments of the potential risks from chemical exposures are necessary for providing both regulators and the regulated community with a useful summary of the science on certain chemicals.

Unfinished business: Changes to IRIS still needed to ensure assessments are based on modern science

The May release of the National Academy of Sciences (NAS) review of the U.S. Environmental Protection Agency’s (EPA) progress in improving the Integrated Risk Information System (IRIS) was accompanied by much fanfare. The “kudos” directed to Ken Olden, who took over the IRIS program two years ago, are well-deserved. Dr. Olden has brought about a [...]

What are the key challenges for improving risk assessments? Two experts weigh in

Two recurring themes at the 53rd meeting of the Society of Toxicology (SOT) in Phoenix, Arizona, were enhancing strategies for risk assessment and finding new ways to conduct safety assessments. Here are three questions (and some potential answers) that continue to drive the debate. What are the biggest issues for the future of risk assessment? [...]

EPA’s new Human Health Risk Assessment (HHRA) framework a step in the right direction

The Environmental Protection Agency (EPA) is offering new guidance for risk analysts who conduct important human health assessments on behalf of the Agency. If you’ll recall, last December, George Mason University conducted a survey of toxicology experts and found widespread agreement on a need for the government to establish clearer policies and better methodology for [...]

What you may have missed at the Society for Risk Analysis meeting

Improving EPA’s Integrated Risk Information System (IRIS) and how to better accommodate diverse types of evidence to evaluate associations and causation were the focus of discussions before standing-room-only crowds at the Society for Risk Analysis (SRA) annual meeting in Baltimore earlier this month. But it’s important not to overlook two other sessions that took place [...]
