Simulating changes in polar bear subpopulation growth rate due to legacy persistent organic pollutants – Temporal and spatial trends

Persistent Organic Pollutants (POPs) are organic compounds that have been banned or restricted for all purposes. Banning these compounds does not guarantee that the chemicals will not be found in the environment. This is related to the persistence nature of POPs. To investigate the presence of POPs in the environment. Environmental monitoring of POPs is one of the efforts to support POPs management. The most frequently discussed pollutants in the last 3 years are polychlorinated biphenyls (PCBs). In addition, an effective method in degrading Persistent Organic Pollutants is the fabrication of ultra-thin graphitic carbon nitride decorated CoFe2O4/Mn3O4 nanosheet membranes with a yield of 94.5% and a kinetic rate (0.1367 min.-1) For norfloxacin (NOR) within 30 minutes. But for a method that uses simple, efficient and affordable technology to remove organic pollutants from aquatic systems is Biosorption using biomass waste, using tannin-rich waste such as coffee grounds and green tea grounds capable of degrading 10 μM chlordecone.

Anthropogenic contamination has been detected in glacial and proglacial environments around the globe. Through mechanisms of secondary release, these contaminants are finding their way into glacial hydrological systems and downstream environments, with potential to impact hundreds of millions of people who rely on glacial meltwater for water, food and energy security worldwide. The first part of our progress report outlined the sources and accumulation mechanisms of contaminants in glacial environments (Part I: Inputs and accumulation). Here we assess processes of contaminant release, pathways to downstream environments, and socio-environmental consequences. We reflect on the potential impacts these contaminants could have for human, ecosystem, and environmental health, as well as framing glacial contaminants within the context of the water-food-energy nexus. Improved understanding of these processes and impacts, while crucially embedding local knowledge, will help to develop key policy and mitigation strategies to address future risk of contaminant release from glaciers.
