Are you aware of the "forever chemicals" present in your drinking water? A recent study by Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) reveals that the Environmental Protection Agency's (EPA) draft standards for maximum allowable levels of PFAS (per- and polyfluoroalkyl substances) in drinking water are not enough to account for half of the PFAS present at contaminated sites across the US. PFAS are linked to several health risks, including cancer, immune suppression, and low infant birth weight. The study emphasizes the urgent need for advances in remediation technology to effectively clean up both terminal and precursor compounds. Read more about this alarming issue in the Environmental Science & Technology journal.

Did you know that air pollution can impair our sense of smell and cause anosmia? Studies have shown that exposure to small airborne pollution particles, largely from the combustion of fuels in vehicles, power stations and our homes, can lead to olfactory dysfunction, causing a gradual erosion of our sense of smell over time. This can have significant effects on our overall wellbeing, from reducing our ability to taste and enjoy food, to potentially being an early warning sign of dementia. Researchers from Johns Hopkins School of Medicine and Karolinska Institute have found a strong correlation between higher pollution levels and poorer smelling ability, suggesting that we need to take air pollution more seriously to protect our health.
Scotland has become the first country to ban desflurane, an anaesthetic gas with a global warming potential 2,500 times greater than carbon dioxide, from its hospitals due to its environmental threat. The move would cut emissions equivalent to powering 1,700 homes a year. UK hospitals have already cut down, with over 40 hospital trusts in England and some in Wales having stopped using it. NHS England will introduce a similar ban from 2024. Anaesthetists have switched to safer alternatives, but more needs to be done to reduce the NHS's carbon footprint.

Plastic is a synthetic polymer that has completely changed our world. It is lightweight, durable, and can be molded into almost any shape. Unfortunately, plastic has saturated our environment, invaded the animals we eat, and is finding its way into our bodies. Plastic takes between 500 and 1,000 years to break down, yet we use it for things meant to be thrown away. 40% of plastics are used for packaging, and since its invention, we have produced about 8.3 billion metric tons of plastic. 79% of it is still sticking around, and a lot ends up in the ocean, where it outweighs all the fish. Microplastics, pieces smaller than 5 millimeters, have been found in honey, sea salt, beer, tap water, and in the household dust around us. While there is little science about the health risks associated with microplastics, it is safe to say that we have lost control over plastic to a certain extent, which is kind of scary. By learning more about plastic, we can take steps to reduce its impact on our environment and our health.

Are you interested in learning about the age of microplastics found in the ocean and how they affect the environment? Researchers from Kyushu University and Asahi Kasei Corporation have developed a new method to estimate the age of microplastics found in the upper oceans. By analyzing plastic oxidation levels with environmental factors such as UV exposure and ambient temperature, they found that microplastics in nearshore regions ranged from 0 to 5 years old, whereas microplastics from offshore regions ranged from 1 to 3 years old. Their findings were published in the journal, Marine Pollution Bulletin.
Brazil's national conservation forest policy aimed to restore natural vegetation in the Amazon, but an amnesty for small property owners has prevented the restoration of 14.6 million hectares of agricultural land. This amounts to 2.4 gigatonnes of potential carbon stock that could have been held in natural vegetation. The study also found that more than half of deforestation in the Brazilian Amazon has taken place within rural private properties. Learn how this policy has failed to protect the Amazon's biodiversity hotspots and how it affects global climate change.
