Polar bears are exposed to TOXIC ‘forever’ chemicals as they are released from melting Arctic ice

Polar bears are being exposed to TOXIC ‘without end’ chemicals as they are released from melting Arctic ice as a results of international warming, examine warns

  • Toxic chemicals in non-stick pans and cosmetics are threatening polar bears
  • Substances are released by manufacturing websites and carried to Arctic by wind
  • They then accumulate within the ice earlier than being released into seawater as it melts
  • It contaminates algae, which zooplankton feed on, and travels up the meals chain

Polar bears are being exposed to poisonous ‘without end’ chemicals utilized in non-stick pans and cosmetics as a results of global warming, a examine has discovered.

High concentrations of the artificial substances are being released into the ambiance by manufacturing websites and carried by the wind from the UK and different highly-populated areas to the Arctic.

They then accumulate within the ice earlier than being released and leaking into seawater as the ice melts within the area’s warming temperatures.

Researchers stated there was proof the chemicals had been disrupting the hormone programs of polar bears after being consumed through their prey.

This graphic shows how 'forever' chemicals are being released from manufacturing plants in highly-populated areas and carried by the wind before accumulating in Arctic ice. Once the ice melts because of global warming the chemicals leak into seawater and contaminate algae, which is then eaten by zooplankton and travels up the food chain to seals and polar bears

This graphic reveals how ‘without end’ chemicals are being released from manufacturing vegetation in highly-populated areas and carried by the wind earlier than accumulating in Arctic ice. Once the ice melts due to international warming the chemicals leak into seawater and contaminate algae, which is then eaten by zooplankton and travels up the meals chain to seals and polar bears

PFAS CHEMICALS CONTAMINATE WATER AND FOOD SUPPLIES

PFAS are artifical chemicals used as oil and water repellents and coatings for frequent merchandise together with cookware, carpets, and textiles.

These endocrine-disrupting chemicals don’t break down when they are released into the atmosphere, and they proceed to accumulate over time.

PFAS chemicals can contaminate consuming water provides close to services the place the chemicals are used.

PFAS contamination has been detected in water close to manufacturing services as properly as army bases and firefighting coaching services the place foam containing PFAS is used.

They additionally enter the meals provide by meals packaging supplies and contaminated soil. 

The poly and perfluoroalkyl substances (PFAS), which don’t break down within the atmosphere, had been found in brine on the underside of the ice in a examine led by researchers from Lancaster University.

This is the primary habitat for organisms on the backside of the marine meals net such as algae. Zooplankton feed on the algae and are in flip eaten by fish and shrimp, which are a supply of meals for seals — the prey of polar bears.

Scientists discovered the PFAS chemicals at up to double the focus noticed within the North Sea. 

This is regardless of the pattern web site within the Barents Sea being hundreds of miles away from the heavily-populated areas of Europe.

Brine — extremely saline water — in Arctic ice was discovered to enhance the buildup of PFAS, which are additionally utilized in waterproof garments and fireproofing processes.

Researchers stated there was proof the chemicals had been disrupting the hormone programs of polar bears after being consumed through their prey.  

Seabirds are additionally in danger, whereas PFAS have been proven to be poisonous to people and linked to a variety of well being points, together with kidney most cancers, testicular most cancers, hypertension, thyroid illness, low beginning weight and immunotoxicity in youngsters.

As properly as manufacturing websites, the chemicals are additionally being released by wastewater therapy vegetation, the place droplets have been contaminated with PFAS washed off supplies utilized in houses and workplaces.

The sea ice within the Arctic used to stay frozen for a number of years however is now melting every summer season as a result of the area is warming at greater than twice the worldwide common charge.  

‘This one-year ice accommodates a whole lot of cellular brine that interacts with the overlying snowpack and might serve to focus pollution like PFAS, which are normally discovered at very low ranges,’ stated Crispin Halsall, co-author of the examine and a professor at Lancaster University.

‘Unfortunately, with earlier and extra erratic thaw occasions, this could lead to the fast launch of the saved chemicals leading to excessive concentrations within the waters surrounding the ice floes.’ 

He added: ‘It is just by such a investigative science that we are able to perceive the dynamics of pollutant behaviour and establish key hazards, notably these associated to local weather change.

‘In flip this could drive worldwide laws in order that chemicals that exhibit such a behaviour are banned.’

HOW MUCH PLASTIC IS IN THE ARCTIC?

The pristine waters of the Arctic are turning right into a floating garbage dump – posing a risk to marine life, scientists warn.

One of the densest areas of plastic garbage anyplace on the planet’s seas has been found north of Norway and Russia.

Miles from civilisation, the quantity of plastic waste within the Barents Sea – on the margins of the Arctic Ocean – has risen nearly 20-fold in simply ten years.

The detritus, which included plastic baggage and fishing nets, was found greater than 8,000ft under the water’s floor.

The litter was logged at two polar analysis stations between Greenland and the Svalbard archipelago – discovered half means between Norway and the North Pole.

The knowledge was recorded by researchers from Germany’s Alfred Wegener Research Institute and printed within the journal Deep-Sea Research I.

In one space, the quantity of waste had risen from 346 items per sq. kilometre in 2004 to 6,333 in 2014.

Scientists now concern the area has turn out to be one of many world’s greatest floating garbage dumps, alongside different zones within the Atlantic, Pacific and Indian Oceans. 

Fishing nets are an enormous supply of plastic air pollution on the Arctic island of Svalbard, with an estimated 80 per cent of plastic garbage coming from fishing.
