“In 2023, emissions of all pollutants were lower than in 2005 (or in 2000 for PM) (Table 3.1).Emission trends for NOX, NMVOCs, SOX, NH3 and PM 2.5 are presented in Figure 3.1. For the main pollutants, the largest reductions, in percent, across the EU were for SOX emissions. SOX reduced by 95% since 1990 and by 14% since the previous reporting cycle. This was followed by NOX,which reduced by 66% since 1990 and by 3% since the previous reporting cycle. NMVOCs reduced by 63% since 1990 and by 4% since the previous reporting cycle. NH3 reduced by 36%since 1990, while the emissions did not reduce since the previous reporting cycle. PM 2.5 reduced by 41% since 2000 and by 6% since the previous reporting cycle.”

“Scientists at the University of Cambridge have identified a family of bacterial species, found naturally in the human gut, that absorb various PFAS molecules from their surroundings.  When nine of these bacterial species were introduced into the guts of mice to ‘humanise’ the mouse microbiome, the bacteria rapidly accumulated PFAS eaten by the mice – which were then excreted in faeces.

The researchers also found that as the mice were exposed to increasing levels of PFAS, the microbes worked harder, consistently removing the same percentage of the toxic chemicals. Within minutes of exposure, the bacterial species tested soaked up between 25% and 74% of the PFAS.

The results are the first evidence that our gut microbiome could play a helpful role in removing toxic PFAS chemicals from our body – although this has not yet been directly tested in humans.

The researchers plan to use their discovery to create probiotic dietary supplements that boost the levels of these helpful microbes in our gut, to protect against the toxic effects of PFAS.”

“Parisians and tourists flocked to take a dip in the Seine River this weekend after city authorities gave the green light for it to be used for public swimming for the first time in more than a century.

The opening followed a comprehensive clean-up programme sped up by its use as a venue in last year’s Paris Olympics after people who regularly swam in it illegally, lobbied for its transformation.

The outgoing mayor of Paris, Anne Hidalgo, also helped to champion the plans, jumping in the river herself before the Olympics.

About 1,000 swimmers a day will be allowed access to three bathing sites on the banks of the Seine for free, until the end of August.”

“Human waste, empty oxygen cylinders, kitchen leftovers and discarded ladders.

Sherpas working on Mount Everest carry all that and more — 20 kilograms (44 pounds) per person — navigating a four-hour hike that traverses crumbling glacial ice and treacherous crevasses to bring trash back to base camp.

During the most recent climbing season, they had new assistance from two giant SZ DJI Technology Co. drones, which can complete the same journey in six minutes, sharing the task of clearing an expanding volume of refuse piling up on the world’s highest peak…

‘We’re very happy,’ said Lhakpa Nuru Sherpa, a 33-year-old Sherpa at local expeditions firm Asian Trekking who has reached the summit of Everest 15 times. He estimates that about 70% of the garbage usually carted off the mountain by his team was transported by drone this year.”
