About Integrated Environmental Assessment and Management
Integrated Environmental Assessment and Management (IEAM) is published quarterly by the Society of Environmental Toxicology and Chemistry (SETAC). The journal is devoted to bridging the gap between scientific research and the use of science in decision making, regulation, and environmental management. IEAM aims to be the premier scientific journal for presenting new information, promoting dialogue, and fostering new methods for analysis of biological, ecological, chemical, engineering, environmental, physical and social science research applicable to the advancement of environmental policy and regulation, environmental management strategies, and sound approaches to environmental problem-solving.
IEAM provides a peer-reviewed international forum for communicating new ideas and information from environmental science professionals in academia, business, government, and nongovernmental organizations. The journal welcomes scientific, social, and regulatory information through critical reviews, original research, commentaries, policy analyses, case studies, and special series. IEAM strives to provide a unique position in the peer-reviewed literature, focusing on continually evolving collaborations by offering perspectives from diverse disciplines and a variety of stakeholders. The internationally recognized scientists, academicians, and policy specialists who serve as subject matter Editors, members of the Editorial Board, and manuscript reviewers reflect this diversity of views and experience in each of the following major topic areas:
Climate change challenges
Ecological and human health risk assessment
Environment impact analysis
Environmental policy and regulation
Life cycle analysis and sustainable environmental practices
In addition, IEAM regularly features non–peer-reviewed Learned Discourses that provide a forum for rapid communication of professional opinions on timely scientific issues, and Book Reviews that alert the scientific community to new publications in the broad field of environmental science.
We face a steady, sobering news stream about the deforestation of the humid tropics, the warming of the Arctic, and more recently, the greening of Antarctica. In contrast, we hear very little about drylands, the arid regions that cover more than 40% of Earth’s land surface. Although the United Nations has periodically focused on drylands, the popular and scientific media have given little coverage to them, partly because of the absence of a focused international program. However, in the past few years, we have been hearing more about drylands, including the recent unveiling of what has been touted as a secret—they are home to large forests, much larger than previously thought.

The heat is on in the Arctic. This region is now warming at a rate faster than twice the global average—known as Arctic amplification. Consequently, the ice that covers the North Pole and surrounding areas, and melts to its lowest extent each September, has been disappearing at an alarming rate. Continue reading →
Microplastics—the tiny bits of plastic that are now infamously and ubiquitously present in the world’s waterways—are polluting aquatic life and ending up in our food supply. As evidence of the damage that microplastics inflict on aquatic life accumulates, so does the amount of microplastics dispersed in oceans, seas, lakes, and rivers. Virtually indestructible in natural environments, these tiny bits of plastic contain a combination of very small particles—microparticles and nanoparticles—that derive from the breakdown of larger plastic items, for example plastic bags and bottles, and include, among others, pre-production plastic pellets (the so-called nurdles), microbeads from personal care products, and microfibers from textiles.
Methane, the primary ingredient of natural gas, has been receiving more bad press than usual lately—courtesy of the massive natural gas leak that erupted on Oct. 23, 2015, at the Aliso Canyon underground storage facility near Los Angeles. California Governor Jerry Brown declared a state of emergency, and thousands of families were evacuated. After unsuccessful initial attempts to plug the leak, Southern California Gas Company was finally able to build a relief well to capture the leaking gas. On February 18, 2016, nearly four months later, officials announced the leak had been permanently sealed.
Microbeads—tiny, plastic beads added to face scrubs, soap, toothpaste, and the like—cause environmental damage at the macro scale. Their function is to provide a bit of grit, but they end up in lakes, rivers, and other aquatic habitats. Once there, microbeads are mistaken for food and gobbled up by zooplankton, thus becoming incorporated into the aquatic food chain. Small fish, and other organisms that swallow the contaminated zooplankton, are eaten by bigger fish and eventually, microbeads make their way to the top of the food chain, reaching other wildlife and even humans. However, there is more to this story. Continue reading →
Pervasive doom and gloom dominates much of the popular news about the environment. Global warming, sea level rise, ocean acidification, drought, wildfires, overfishing, or overpopulation—it all contributes to a feeling of despair and hopelessness, particularly among young people. This struck home for me on a personal level during a recent conversation with my college-aged son and a few of his friends—they felt they were “totally screwed” because of the inevitable impacts of climate change.
On August 3, 2015, the Obama administration announced the finalized US Environmental Protection Agency’s (EPA) “Clean Power Plan.” The plan has been developed under the Clean Air Act and aims to slash carbon emissions from US power plants, which account for one-third of all carbon emissions in the country, by giving each state an individual goal for cutting these emissions. The EPA estimates that the new national standards will significantly decrease carbon pollution produced by the electric sector by 2030; carbon emissions will be 32% lower than the 2005 levels. For a step-by-step guide on how the Clean Power Plan works, head here. Continue reading →
