Are Fish Consumption Advisories for the Great Lakes Adequately Protective against Chemical Mixtures?

Abstract:

Background: The North American Great Lakes are home to > 140 types of fish and are famous for recreational and commercial fishing. However, the presence of toxic substances has resulted in the issuance of fish consumption advisories that are typically based on the most restrictive contaminant.

Objectives: We investigated whether these advisories, which typically neglect the existence of a mixture of chemicals and their possible additive adverse effects, are adequately protective of the health of humans consuming fish from the Canadian waters of the Great Lakes.

Methods: Using recent fish contaminant monitoring data collected by the government of Ontario, Canada, we simulated advisories using most-restrictive-contaminant (one-chem) and multi-contaminant additive effect (multi-chem) approaches. The advisories from the two simulations were compared to determine if there is any deficiency in the currently issued advisories.

Results: Approximately half of the advisories currently issued are potentially not adequately protective. Of the four Great Lakes studied, the highest percentage of advisories affected are in Lake Ontario if an additive effect is considered. Many fish that are popular for consumption, such as walleye, salmon, bass and trout, would have noticeably more stringent advisories.

Conclusions: Improvements in the advisories may be needed to ensure that the health of humans consuming fish from the Great Lakes is protected. In this region, total polychlorinated biphenyls (PCBs) and mercury are the major contaminants causing restrictions on consuming fish, whereas dioxins/furans, toxaphene, and mirex/photomirex are of minor concern. Regular monitoring of most organochlorine pesticides and metals in fish can be discontinued.

Abstract:

Although some advocates of the circular economy still interpret it as simply increasing recycling rates, it is clear to anyone with a chemical engineering background that the key to resource efficiency is to get best value from materials and products in use -- the stock -- and reduce their flow through the economy.


4 ways AI helps business protect the environment

Abstract:

Growing global attention is leading to increasing regulations, deeper research and deployment of advanced sensing and mapping technologies. However, connecting the dots for better insights and solutions is difficult because the relevant information is often siloed, and decision makers are reluctant to act without a high degree of certainty. Today's complex supply chains make this an even tougher puzzle to unravel. Cognitive technology, enabled by artificial intelligence, or AI, is uniquely adapted to helping with these challenges, from finding patterns and interconnections within macro datasets to providing local, personalized diagnosis and predictions that learn and improve over time. With its ability to understand, reason and learn, cognitive technology is proving a great ally in protecting our planet in four key ways.

Abstract:

The Metropolitan Water Reclamation District of Greater Chicago (MWRD) has set a target to be energy-neutral by 2023, following the lead of plants in the United Kingdom, Denmark and the East Bay Municipal Utility District in Oakland, California, which has moved beyond net-zero energy to actually selling energy back to the grid. These innovators are using a variety of technologies to reduce the electricity they use through energy efficiency and to generate electricity onsite to offset what they do use.

Abstract:

Walmart is doubling down on its climate commitment. Today, the retail giant announced Project Gigaton, a goal to remove 1 billion metric tons of greenhouse gases from its supply chain by 2030, equivalent to taking more than 211 million passenger vehicles off the road for a year, the company said.

Abstract:

Nike has developed new sustainable packaging for its shoes, working in collaboration with Arthur Huang, the CEO and founder of Taiwanese firm Miniwiz, which recycles consumer and industrial waste into new products.

The lightweight packaging is made entirely of post-consumer materials such as milk and orange juice containers, and morning coffee lids. The box is produced from a single process Polypropylene with no added chemicals. The modular design allows it to be used as a stackable, interlocking component of a product display or storage system, Nike says.
