Dans la lutte que mènent nos villes contre la pollution urbaine, on perçoit la recherche désespérée de solutions alternatives aux véhicules conventionnels. C’est le cas en particulier pour les particules fines, même s’il est de bon ton de passer sous silence que le chauffage contribue aussi largement à cette pollution….

Earlier this year, DEFRA published a report by the Air Quality Expert Group into the impacts of biomass on air quality. The results make for startling reading.
Among the findings are: (…) (…)

The New York Times’ article breathlessly reports:
“From the 1950s to today, 8.3 billion metric tons of plastic have been produced, with around half of it made since 2004. And since plastic does not naturally degrade, the billions of tons sitting in landfills, floating in the oceans or piling up on city streets will provide a marker if later civilizations ever want to classify our era. Perhaps they will call this time on Earth the Plastocene Epoch.”

Globally emitted contaminants accumulate in the Arctic and are stored in the frozen environments of the cryosphere. The microbial potential to degrade anthropogenic contaminants, such as toxic and persistent polychlorinated biphenyls, was found to be spatially variable and not limited to regions close to human activities.

The levels of microplastic particles accumulating in the Antarctic are much worse than expected, a team of experts has warned.
The continent is considered to be a pristine wilderness compared to other regions and was thought to be relatively free from plastic pollution. However new findings by scientists from University of Hull and British Antarctic Survey (BAS) have revealed that recorded levels of microplastics are five times higher than you would expect to find from local sources such as research stations and ships

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information.
