Neglected oil and gas pipelines deteriorating in the North Sea pose a potential hazard, as they may discharge significant amounts of hazardous substances such as mercury, radioactive lead, and polonium-210, infamous for its role in the poisoning of Russian defector Alexander Litvinenko, caution scientists.

Mercury, a highly toxic element present naturally in oil and gas, adheres to the interior of pipelines and accumulates over time, eventually being released into the sea as the pipelines corrode.

Methylmercury, the most toxic form of the metal, is emitted by these pipelines, with other forms potentially converting into it. The Minamata Convention on Mercury internationally warns that elevated mercury levels in marine mammals like dolphins, whales, and seals can lead to "reproductive failure, behavioural changes, and even death." Seabirds and large predatory fish, such as tuna and swordfish, are also particularly at risk.

Lhiam Paton, a researcher at the University of Graz’s Institute for Analytical Chemistry, who has highlighted the mercury pollution issue, emphasises that even a slight rise in sea mercury levels can have a significant impact on top-of-the-food-chain animals.

The North Sea harbors approximately 27,000 km of gas pipelines, and experts estimate that the metal concentration in the sea could surge anywhere from 3 per cent to 160 per cent&nbsp;above current levels. Unlike some countries where regulations mandate the removal of pipelines after oil well cessation, North Sea companies are permitted to leave them to deteriorate.

Paton, whose findings are published in the Journal of Hazardous Materials, warns that pipelines left on the seabed may retain substantial amounts of mercury, waiting to be released into the local marine environment as they corrode post-decommissioning. The impact on wildlife and food chains will depend on the form of mercury released, with certain forms less likely to be absorbed by marine life. Researcher Dr. Darren Koppel emphasises the need to understand the long-term fate of mercury in contaminated pipelines and the conditions leading to its integration into food webs.

In addition to mercury, scientists are concerned about naturally occurring radioactive materials, such as radium, present in some underwater oil and gas reservoirs. These materials may accumulate as scales inside subsea pipelines, with potential radiological risks to marine organisms. Experts stress the necessity for further research to comprehend the environmental impact fully.

Hugo Tagholm, executive director of Oceana UK, describes the situation as another instance of the severe harm caused by oil and gas developments on marine wildlife, emphasising mercury's neurotoxic effects. Despite being a signatory to the Minamata convention, aimed at addressing mercury pollution, the UK has recently granted new oil and gas licenses in the North Sea. Concerns are raised about the potential risks to the rich biodiversity of the North Sea and the millions dependent on it.

Responding to these concerns, Offshore Energies UK decommissioning manager Ricky Thomson asserts the industry's commitment to meeting obligations under national and international regulations.

However, concerns persist, with experts emphasising the need for transparency, collaboration, and ongoing research to address the potential environmental consequences of neglected pipelines. Worldwide, there are approximately 1.3 million km of installed oil and gas pipelines.

Abandoned pipelines pose threat of releasing toxins into North Sea, scientists issue warning

Muttahida Qaumi Movement (MQM) founder Altaf Hussain has claimed that former Pakistan Prime Minister Nawaz Sharif has been given polonium, the drug which slowly poisoned Yasser Arafat, famed Palestinian President, to death in 2004.

"Lower platelets count in Nawaz Sharif's body! A known fact is that 'Polonium' (a radioactive element) is used to eliminate enemies. It acts as a slow poison and destroys platelets. The only specialised radioactive laboratory can verify it. The international laboratory must examine it," Hussain first tweeted on November 2.&nbsp;

On Tuesday, Hussain posted a research article -- 'Polonium - A Perfect Poison' — on his Twitter handle after several questions were put up to him regarding his earlier post on the micro-blogging site."Dear Students and Followers! Here is my research article on 'Polonium-A Perfect Poison' in reply to questions put up by people about my 2nd November 2019 tweet regarding #Polonium. I tried my level best to give answers on this important subject. Please read it thoroughly," Hussain wrote alongside the article, which briefs about polonium, its symptoms and treatment.

"Besides Yasser Arafat, Irene Joliot Curie (1956), a Nobel Laureate and daughter of Madam Curie and Alexander Litvinenko (2006) are some of the known/suspicious victims of polonium poisoning," Hussain has claimed in his article.

"The mysterious and deteriorating medical condition of any person exposed to polonium need some serious screening and thorough investigations from globally recognised and reputed radioactive laboratories," said Hussain.&nbsp;

Polonium radiation destroys DNA and can lead to cell death and cancer. It is a known carcinogen. When inhaled, polonium causes lung cancer.&nbsp;

When swallowed, it becomes concentrated in red blood cells, before spreading to other important organs like liver, kidneys, and bone marrow.&nbsp;

Sharif was discharged from the Services Institute of Medical Sciences (SIMS) in Lahore and shifted to his residence -- Jati Umra -- on Wednesday.&nbsp;

The 69-year-old leader was admitted to the SIMS on October 22 after his health conditions deteriorated drastically due to "critically" low platelet count.

An Intensive Care Unit (ICU) has been set up at Sharif`s residence and the doctors have put a ban on the people visiting him, Marriyum Aurangzeb, spokesperson of the Pakistan Muslim League-Nawaz (PML-N), said in a statement.

Adding that there were chances that an infection might develop due to low platelet counts, Aurangzeb said the doctors had suggested the setting up of a special medical unit at Sharif`s residence."The unit was set up under the supervision of Sharif`s personal physician Dr Adnan Khan and the doctors will be present in the ICU round the clock," she added.

While being shifted to his residence from the hospital, Sharif was accompanied by his mother, daughter Maryam Nawaz and other family members. On October 29, Sharif was granted bail by the Islamabad High Court on medical grounds in connection with Al Azizia and Chaudhry Sugar Mills corruption cases.&nbsp;

The ailing Pakistani leader was serving a seven-year imprisonment in the Al-Azizia case in Kot Lakhpat jail in Lahore. Besides this, he was remanded to the NAB custody in Chaudhry Sugar Mills case.&nbsp;
