Shutdown of coal-fired plants in U.S. saves lives and improves crop yields

The decommissioning of coal-fired power plants in the continental United States has reduced nearby pollution and its negative impacts on human health and crop yields, according to a new University of California San Diego study. The findings published this week in Nature Sustainability use the U.S. transition in recent years from coal towards natural gas for electric … Read more

Why polar bears at sea have higher pollution levels than those staying on land

As the climate changes, myriad animal populations are being impacted. In particular, Arctic sea-ice is in decline, causing polar bears in the Barents Sea region to alter their feeding and hunting habits. Bears that follow sea-ice to offshore areas have higher pollutant levels than those staying on land – but why? A new study in … Read more

Harbor porpoise calves exposed to neurotoxic PCBs in mothers’ milk

Harbour porpoise calves around the UK are carrying a more neurotoxic cocktail of PCBs than their mothers, as females unknowingly detoxify themselves by transferring the chemicals while feeding their young, new research reveals today. Published in the Science of the Total Environment today (Tuesday 3 December 2019) and led by Cetacean Strandings Investigation Programme (CSIP) scientists from … Read more

High pesticide concentrations continue to enter Great Barrier Reef

The combined toxicity of 22 of the most common pesticides found in waterways flowing into the Great Barrier Reef is in many cases not meeting pollution reduction targets. University of Queensland researchers, along with the Queensland Department of Environment and Science, reached the conclusion after devising a new method to estimate the percentage of species … Read more

Atmospheric pressure impacts greenhouse gas emissions from leaky oil and gas wells: UBC study

Fluctuations in atmospheric pressure can heavily influence how much natural gas leaks from wells below the ground surface at oil and gas sites, according to new University of British Columbia research. However, current monitoring strategies do not take this phenomenon into account, and therefore may be under- or over-estimating the true magnitude of gas emissions. … Read more
