IEAM Podcast

Nanomaterials are small but key components in consumer products like electronics, sunscreens, and antimicrobial clothing, just to name a few. Despite their widespread use, scientists are still struggling to assess their potential hazards, with regulatory policy hinging on these assessments. Author Rune Hjorth discusses how alternatives assessment frameworks can be adapted to evaluate nanomaterials.

Human activities and other pressures on marine ecosystems are ever increasing, underscoring the need for responsible, sustainable management. Several types of environmental assessment exist, but which is the most appropriate for your assessment needs? Enter CUMULEO, a framework that defines common EA elements and introduces consistency, while remaining adaptable to assessments for marine and other ecosystems. We chat with Ruud Jongbloed to get the highlights of CUMULEO.

We benefit from ecosystem services (ES) everyday - the water we drink, the food we eat, even the vacation at the beach. It is widely recognized that we need to protect the ecological processes that deliver these benefits, yet ES have not yet been formally incorporated into environmental risk assessment, one of the primary methods that inform regulatory decision making. Wayne Munns discusses the reasons for and challenges to the routine inclusion of ES endpoints in ERAs.

Although many people confuse the terms remediation and restoration, they are two separate processes in the restoration of impaired ecosystems. IEAM challenges practitioners and researchers to rethink the traditional linear, sequential process of ecological restoration, instead encouraging a collaborative approach along the way, to integrate restoration goals throughout the process, beginning with site assessment. Guest Editors Aida Farag and Ruth Hull discuss workshop findings findings and tell us why we should heed an ounce of prevention when restoring ecosystems.

Think you know stats? Stuart Hurlbert first described pseudoreplication—a common but serious statistical error—in 1984. Despite widespread knowledge of the error, pseudoreplication is often misinterpreted, and literature surveys show that the error is on the rise in certain fields. Listen to Hurlbert define pseudoreplication and other related errors, plus hear why we shouldn’t dichotomize results as “significant” and “non-significant,” what’s missing from basics stats courses, and what’s next on his list.

The 27 oil and gas platforms off the southern California coast are aging quickly. What’s next for an oil rig once it reaches the end of its useful life? Should it be broken down and the ocean floor restored? Should it be turned into an artificial reef, since it has already been colonized by marine life for decades? Deciding the fate of these massive hulks of steel and machinery is no simple feat, and this issue’s podcast highlights a group of articles whose authors that set out to do exactly that. In the special series “Offshore Platform Decommissioning in California,” Brock Bernstein and his co-authors evaluate the options for the aging platforms in southern California, which include some of the largest and deepest platforms ever built. Access the series in the October 2015 issue of IEAM.

“Going green” has become a sweeping campaign for consumers at all levels. One way to become more environmentally responsible is to practice reuse—the second of the three R’s in the mantra “Reduce, Reuse, Recycle.” Although reusing items such as clothing or furniture may seem like a logical way to decrease one’s environmental footprint, measuring the environmental benefits conferred by reuse is not as obvious as, for example, a reduction in energy usage. In this podcast, we chat with Valentina Castellani, who used life cycle assessment to quantify the environmental impacts avoided by the reuse of commonplace items through a secondhand store, over the course of one year. Her article “Beyond the throwaway society: A life cycle-based assessment of the environmental benefit of reuse” is part of the special series “SETAC LCA Case Study Symposium 2013.” Access her article and the entire series in the July 2015 issue of IEAM.
