The French town that banned its tap water and the chemicals that could be in yours

The French town that banned its tap water and the chemicals that could be in yours

The Guardian14 hours ago
Sandra Wiedemann was watching TV on a Saturday night when she first saw the news that the water where she lived was contaminated.
Then, three days later – right at the end of April – it was made official. Sandra and 60,000 other residents of Alsace, eastern France, were told by the local government that it had found dangerously high levels of PFAs – or 'forever chemicals' – in the water.
Those in high-risk groups – under-twos, immunocompromised people, pregnant women – were advised not to drink water from the taps for the rest of year.
The Guardian's biodiversity reporter Phoebe Weston heads to Alsace to speak to residents and activists, and goes to the local spot that has caused the contamination.
As she tells Helen Pidd, it's a story that is unlikely to be limited to Alsace. For PFAs are used on an industrial scale right around the world. Valued because they just don't break down, they are used in products from non-stick frying pans to waterproof jackets. But the same quality means they are now found right across the environment too – from in the water and earth beneath our feet to inside even our blood.
So, if the water in Alsace has been deemed too dangerous to drink, what does it mean for the rest of the world?

Vet addresses myths about travelling with dogs in heatwave

Warnings for extreme heat have been extended across much of England, with temperatures expected to reach up to 34C. A French Bulldog died from heatstroke after being trapped in a hot car, prompting experts to issue warnings for pet owners. Aysha Kent, a vet at Blue Cross, urged owners to avoid travelling with pets during the heatwave due to potentially fatal consequences, emphasizing that car temperatures are often higher than perceived. Flat-faced breeds like French Bulldogs, as well as overweight, very young, elderly, or thick-coated pets, are particularly vulnerable to heatstroke. Owners are advised to skip normal walks, provide chilled treats and shade, and recognize heatstroke symptoms like excessive panting or collapse, seeking immediate veterinary attention if observed.

Scientists want to use giant PARACHUTES to stop the Gulf Stream collapsing – in controversial geoengineering experiment to combat global warming

As climate change disrupts the planet, experts are worried that a key ocean current called the Atlantic Meridional Overturning Circulation (AMOC) may collapse. This current is responsible for driving the Gulf Stream and bringing warm water from the tropics northwards to keep Europe temperate. Now, scientists have proposed a radical solution to save these vital systems and prevent Europe from slipping into a new Ice Age. Researchers say tugboats could tow huge underwater parachutes around the ocean to manually power the current. Each parachute would be the size of half a football field and would feature a 12-metre hole in the centre to allow ocean life to pass through. Just 30 to 50 shipping tankers, drones, fishing boats, or wind kites operating 365 days a year could be enough to power the entire Atlantic Meridional Overturning Circulation (AMOC). Professor Stuart Haszeldine, of the University of Edinburgh, and David Sevier, founder of water treatment Strengite, presented the idea at the Arctic Repair conference in Cambridge this week. Professor Haszeldine told MailOnline: 'We think that this is a remedy well worth trying - because we want to keep the flows of ocean current similar to what we know works well just now.' The AMOC is the largest ocean current in the world and runs from south to north through the Atlantic Ocean. As warm water travels northwards from the tropics, it hits the sea ice around Greenland and the Nordic countries, cooling and becoming much saltier. As the water cools, it becomes denser, sinking rapidly towards the bottom of the ocean where it flows back southwards before once again warming and rising to the surface. This process of 'deep water formation' is the engine for a vast global conveyor belt which pumps heat and water all around the Atlantic Ocean. However, climate change is now melting the northern sea ice and warming the ocean, sparking fears that the engine driving this current could soon stall. The effects of an AMOC collapse would be devastating, leaving European countries 5-20°C (9-36°F) colder and drastically weakening the Gulf Stream. Professor Haszeldine says: 'Our proposition is made in the realisation that there is a real risk that the AMOC current could decrease and falter in the next 20 or 50 years.' If it does begin to falter, these scientists suggest that existing technology could be adapted to keep the current moving. What is the AMOC? The Gulf Stream is a small part of a much wider system of currents, officially called the Atlantic Meridional Overturning Circulation or AMOC. Described as 'the conveyor belt of the ocean', it transports warm water near the ocean's surface northwards - from the tropics to the northern hemisphere. When the warm water reaches the North Atlantic (Europe and the UK, and the US east coast), it releases the heat and then freezes. As this ice forms, salt is left behind in the ocean water. Due to the large amount of salt in the water, it becomes denser, sinks, and is carried southwards – back towards the tropics – in the depths below. Eventually, the water gets pulled back up towards the surface and warms up in a process called upwelling, completing the cycle. Scientists think AMOC brings enough warmth to the northern hemisphere that without it, large parts of Europe could enter a deep freeze. 'The key point is to use surface shipping, which can tow a specially designed sea anchor behind the shipping, at a controlled depth,' says Professor Haszeldine. Parachutes, similar to current sea anchors used to hold ships in place, would be towed in the direction of the existing AMOC flow. The ships would only need to move just faster than the AMOC itself moves, no more than 2.5 miles per hour (4 kmph) - or about walking speed. Although the AMOC moves vast quantities of heat around the globe, Professor Haszeldine says its overall kinetic energy is relatively small. By selecting areas where the AMOC current is shallow enough to reach with a parachute and concentrated enough for the ships to make an impact, only a handful of ships will be needed. These ships will need to be in motion 24 hours a day, 365 days a year, on rotating shifts. However, Professor Haszeldine says this would be 'a small amount of kinetic movement' to produce a large impact on moving heat. Their research estimates that the required energy would be no more than that produced by a small offshore wind farm each year. If biodiesel is used, this would produce approximately 2.6 million tonnes of CO2 per year, which the researchers say is a 'very low' impact compared to the benefits. However, the proposal has been met with scepticism by leading AMOC researchers. Dr René van Westen, of Utrecht University, told MailOnline: 'The AMOC carries 17 million cubic meters of water per second - for reference, one million cubic meters of water per second is equivalent to the globally combined river discharge. 'I can't imagine that one can displace that amount of water with parachutes.' Even if parachutes could be effective, Dr van Westen says that they would only strengthen the upper wind-blown portion of the AMOC current. This section extends between 100 and 500 metres beneath the surface but only affects a small part of the ocean current's overall movement. Deeper currents are primarily driven by the sinking of colder water due to density differences across the Atlantic Ocean. It is this part of the current which is most at risk of collapsing due to climate change's impact on the Arctic. Dr van Westen says: 'The sinking is a crucial part of the AMOC, and you do not change this with the surface winds. Likewise, Professor Meric Srokosz, of the National Oceanography Centre in Southampton, told MailOnline: 'The physics just doesn't work.' Professor Srokosz says: 'In rather simplistic terms, think about pushing water along with your hand in the bath, it won't sink but rather flow round the sides of your hand. 'Even if you could move the water along, you still need to make it sink.' ATLANTIC OCEAN CIRCULATION PLAYS A KEY ROLE IN REGULATING THE GLOBAL CLIMATE When it comes to regulating global climate, the circulation of the Atlantic Ocean plays a key role. This is due to a constantly moving system of deep-water circulation often referred to as the Global Ocean Conveyor Belt which sends warm, salty Gulf Stream water to the North Atlantic where it releases heat to the atmosphere and warms Western Europe. The cooler water then sinks to great depths and travels all the way to Antarctica and eventually circulates back up to the Gulf Stream. This motion is fuelled by thermohaline currents – a combination of temperature and salt. It takes thousands of years for water to complete a continuous journey around the world. Researchers believe that as the North Atlantic began to warm near the end of the Little Ice Age, freshwater disrupted the system, called the Atlantic Meridional Overturning Circulation (AMOC). Arctic sea ice, and ice sheets and glaciers surrounding the Arctic began to melt, forming a huge natural tap of fresh water that gushed into the North Atlantic. This huge influx of freshwater diluted the surface seawater, making it lighter and less able to sink deep, slowing down the AMOC system.

Eating tinned food favourite daily triggered deadly poisoning - I was shocked by the safe limit

An office worker has claimed eating tuna three times a day for months left her with life-threatening mercury poisoning. Nasha Montgomery, 29, from Alabama in the US, spent four months at the end of 2021 batch-cooking salads with tuna for its hefty protein quantity. She would eat it with crackers for breakfast, in sandwiches for lunch and as a snack at work daily. It meant she was consuming around six tins in total per week, or around 1.5kg. But, as she revealed in a recent social media video, she began feeling sick after a couple of months, and suffering muscle cramps, tingling in her hands and feet, and a metallic taste in her mouth. The results of a blood test taken during a routine check-up came back normal—so she put it down to stress related to her new job in office management. But when her condition failed to improve she returned to the doctor, who asked if she'd been eating large quantities of any food in particular. 'I said tuna,' she recalled. A more detailed blood test subsequently revealed 'high levels' of the metal mercury in her body. Doctors diagnosed her with suspected mercury poisoning—when the toxic metal builds up inside the body, causing a range of symptoms including memory problems, numbness, tremors and, in the most severe cases, permanent and lethal brain and kidney damage. Fish with the highest level of mercury include shark, swordfish, tuna and king mackerel. According to studies, mercury poisoning is a risk if you eat more than 25 tins of tuna a week, or around 16 tuna steaks. However some types, like albacore, which Ms Montgomery was eating, contain higher amounts of the metal. Those trying to have a baby or who are pregnant should not eat more than two cans of tuna or two tuna steaks a week due to the risk of mercury poisoning to a baby. Speaking of her diagnosis, Ms Montgomery said: 'I was in shock as I thought I was doing something right by eating the tuna. 'It was healthy, and the things I was eating the tuna with were also healthy. 'I felt like I was doing right by myself but too much of a good thing can always backfire.' Doctors advised her to cut tuna out of her diet for six to eight months, until all the symptoms had vanished. 'I basically had to detox from tuna. I was detoxing like I was addicted to it,' she said. I'm now very careful now about my fish choices. 'Sometimes I do feel tingly or numbness in my fingers and feet but aside from that I haven't experienced any long-term effects.' Treatment options other than stopping exposure for mercury poisoning involve chelation therapy—whereby a machine removes metals from the body via an IV drip. However, the best treatment option will depend on how you consumed or came into contact with mercury. For example, other options are dialysis and surgery which can physically remove mercury from the body. Mercury ends up in fish due to a build-up in the ocean, which happens due to mining and burning coal. In the UK, the government says the maximum level for mercury allowed in tuna products is 1.0g/kg. Last year, Foodwatch and Paris-based NGO Bloom, found 148 cans of tuna, from five European countries, all tested positive for mercury. One tin bought in a Paris Carrefour City store had a record level of 3.9 mg/kg, the report said—13 times the 0.3 mg/kg limit. Bloom and Foodwatch urged European nations to 'activate a safeguard clause' to prevent the sale and promotion of products exceeding 0.3mg/kg. They also called on governments to remove 'all products' with tuna from school canteens, nurseries, maternity wards, hospitals and care homes. However, the UK Foods Standard Agency said: 'The study shows a relatively small number of products were above the legal limit. 'Out of 30 products from the UK market, just one product was found which may be over the legal level.
