BfR ‘consensus statement’ on EDCs reinforces 5 key principles underpinning risk-based model of regulation

When reports surfaced last month that nearly two dozen scientists had gathered in Berlin to reach an “expert consensus” on how to identify endocrine disrupting chemicals (EDCs), it wasn’t immediately clear who attended, how they were selected, or how – or even if – the European Commission would use some of the outcomes to help […]

How do various screening tools evaluate different chemicals?

Retailers and product manufacturers are increasingly using a variety of tools, lists and other approaches to determine whether specific chemical ingredients in consumer products may be a concern, or to certify what some call “greener” chemical ingredients. But what sort of information do these various tools provide? To address this question, a group of researchers […]

What a “defective” radiation-risk standard can teach us about improving chemical risk assessments

Wall Street Journal editorial board member Holman W. Jenkins, Jr. seems to have a knack for battling bad science – especially what he perceives to be misguided reporting and alarmist stories about climate change. In his most recent piece, Jenkins laments the fact that some activists have used faulty research to overstate the risks associated […]

No shortcuts to sound science

One of the most important jobs a public health researcher can undertake is asking stimulating questions that could, through meticulous and valid research, help policymakers make informed decisions about how best to protect human health and the environment. But it is a long journey from raising initial questions, to designing and conducting robust research, to […]

Fixing EPA’s chemical assessment program – Latest reviews show IRIS is still a work in progress

It’s hard to believe but this year marks the fifth anniversary of the National Academy of Sciences’ (NAS) 2011 report on the Environmental Protection Agency’s (EPA) Integrated Risk Information System (IRIS) program. The report identified systemic problems and offered sweeping recommendations to overhaul the program. So what has happened in the five years since the […]

Tying up loose ends: How transparency and reproducibility can help improve chemical assessments

Two basic scientific principles, transparency and reproducibility, which reportedly “saved the universe as we know it,” could also help bring the scientific method back to chemical risk assessment. This post will attempt to explain why these principles are critical and how the scientific community could help make that happen. Back in 2011, scientists appeared to […]

ACC senior director of science and research addresses questions raised by the Halifax Project

For centuries, the scientific method has made possible tremendous advances in science. It’s played an instrumental role in giving us just about everything we know today about how chemicals interact with the human body and the environment. One toxicological principle to emerge from the scientific method centuries ago, and which continues to stand the test […]

IRIS progress report details key improvements, but the bar must be raised higher

According to a May 2015 progress report to Congress, the Environmental Protection Agency’s (EPA) Integrated Risk Information System (IRIS) is better off than it was a year ago, but not as effective as it needs to be to deliver timely, high-quality and credible chemical risk assessments. EPA does deserve credit, first and foremost, for following […]

What you may have missed at SOT: How ‘show and tell’ can lead to a greater understanding of chemical assessment results

Scientists are exploring new visual approaches to improve how chemical hazard values (and their inherent uncertainties) are determined and communicated to risk managers and the public so that we can all make more informed decisions about the safety of chemicals. At the Society of Toxicology (SOT) Annual Meeting in San Diego last month, Drs. Nancy […]

GlobalChem and the road ahead: Why this year’s conference marks the halfway point for one of the most transformative decades for the industry and regulations

ACC Vice President of Regulatory and Technical Affairs Mike Walls kicked off Tuesday’s GlobalChem regulatory conference with a prediction: “Ten years from now,” Walls said, “We will look back at 2015 as the inflection point in one of the most transformative decades for shaping chemical policy.” If you think about it, it’s easy to see […]
