Plastic particles in drinking water present ‘low’ risk — World Health Organization

  • WHO issues first report on microplastics in drinking water
  • Reassures consumers that risk is low, but says more study needed

GENEVA: Microplastics contained in drinking water pose a “low” risk to human health at current levels, but more research is needed to reassure consumers, the World Health Organization (WHO) said on Thursday.
Studies over the past year on plastic particles detected in tap and bottled water have sparked public concerns but the limited data appears reassuring, the UN agency said its first report on potential health risks associated with ingestion.
Microplastics enter drinking water sources mainly through run-off and wastewater effluent, the WHO said. Evidence shows that microplastics found in some bottled water seem to be at least partly due to the bottling process and/or packaging such as plastic caps, it said.
“The headline message is to reassure drinking water consumers around the world, that based on this assessment, our assessment of the risk is that it is low,” Bruce Gordon of the WHO’s department of public health, environmental and social determinants of health, told a briefing.
The WHO did not recommended routine monitoring for microplastics in drinking water. But research should focus on issues including what happens to chemical additives in the particles once they enter the gastrointestinal tract, it said.
The majority of plastic particles in water are larger than 150 micrometers in diameter and are excreted from the body, while “smaller particles are more likely to cross the gut wall and reach other tissues,” it said.

Health concerns have centered around smaller particles, said Jennifer De France, a WHO technical expert and one of the report’s authors.
“For these smallest size particles, where there is really limited evidence, we need know more about what is being absorbed, the distribution and their impacts,” she said.
More research is needed into risks from microplastics exposure throughout the environment — “in our drinking water, air and food,” she added.
Alice Horton, a microplastics researcher at Britain’s National Oceanography Center, said in a statement on the WHO’s findings: “There are no data available to show that microplastics pose a hazard to human health, however this does not necessarily mean that they are harmless.”
“It is important to put concerns about exposure to microplastics from drinking water into context: we are widely exposed to microplastics in our daily lives via a wide number of sources, of which drinking water is just one.”
Plastic pollution is so widespread in the environment that you may be ingesting five grams a week, the equivalent of eating a credit card, a study commissioned by the environmental charity WWF International said in June. That study said the largest source of plastic ingestion was drinking water, but another major source was shellfish.
The biggest overall health threat in water is from microbial pathogens — including from human and livestock waste entering water sources — that cause deadly diarrheal disease, especially in poor countries lacking water treatment systems, the WHO said.
Some 2 billion people drink water contaminated with faeces, causing nearly 1 million deaths annually, Gordon said, adding: “That has got to be the focus of regulators around the world.”


Venezuela’s rival factions take power struggle to UN after talks fail

Venezuela’s rival factions take power struggle to UN after talks fail

  • Guaido is seeking to get more countries, especially the European Union, to implement sanctions on Venezuela
  • Maduro calls Guaido a US puppet seeking to oust him in a coup

CARACAS/WASHINGTON: Venezuela’s rival political factions will take their power struggle to New York next week, where representatives of President Nicolas Maduro and opposition chief Juan Guaido will each try to convince a gathering of world leaders at the United Nations that their boss is the country’s legitimate head of state.
The United States and more than 50 other countries recognize Guaido, the leader of the opposition-controlled National Assembly, as the rightful president. Guaido in January invoked the constitution to assume a rival presidency to Maduro, arguing the socialist president’s May 2018 re-election was a sham.
But the 193-member UN General Assembly still recognizes Maduro, who retains the support of the UN Security Council’s veto-wielding permanent members Russia and China, setting the stage for the two sides to air their public grievances as they battle for international backing.
A round of negotiations brokered by Norway in recent months, aimed at peacefully resolving the crisis, has failed.
Guaido is seeking to get more countries, especially the European Union, to implement sanctions on Venezuela, as the United States has done.
Maduro, who has overseen a collapse of the OPEC nation’s once-prosperous economy and has been accused by the UN’s High Commissioner for Human Rights of rights violations, wants to heap pressure on the United States to lift sanctions on state oil company PDVSA and members of his inner circle.
Critics say his government’s decisions this week to free a jailed opposition lawmaker and reform Venezuela’s electoral body, long accused of bias, were aimed at improving Maduro’s image before the UN gathering.
“They want to use the UN meeting to wash their face, because they are not reaching any real solutions for the Venezuelan people,” Carlos Valero, an opposition lawmaker who sits on the National Assembly’s foreign affairs committee, said in an interview on Wednesday.
Maduro calls Guaido a US puppet seeking to oust him in a coup, and blames Washington’s sanctions for Venezuela’s economic woes. Maduro himself said he will not attend the UN gathering, but he tasked two cabinet members with presenting a petition condemning the sanctions to Secretary General Antonio Guterres.
“The UN Secretary General and all the UN agencies should raise their voice to condemn the aggression Venezuela is being subjected to, to condemn the illegal blockade,” Foreign Minister Jorge Arreaza told reporters in Geneva last Friday. “We believe that a lot more can be done from the United Nations.”
’Until Maduro is gone’
Guaido has not yet decided whether he will attend, according to his US envoy Carlos Vecchio. Julio Borges, an exiled opposition lawmaker recently named Guaido’s chief diplomat, will be in New York for side events aimed at spotlighting Venezuela’s humanitarian crisis and Maduro’s alleged support for armed rebels in Colombia.
The events include a likely meeting of the signatories of the Rio Treaty, invoked earlier this month by a dozen members of the Organization of American States (OAS), including the United States. The treaty is a Cold War-era mutual defense pact that the countries said they had invoked in response to what they called Maduro’s threat to regional stability. The OAS, unlike the UN, recognizes Guaido as Venezuela’s rightful leader.
Maduro’s government denies supporting the Colombian rebels and says the Rio Treaty is a precursor to military intervention.
In April, US Vice President Mike Pence called on the UN to revoke the credentials of Maduro’s government and recognize Guaido, but Washington has taken no action to push the measure at the General Assembly. Diplomats said it was unlikely Washington would get the support needed.
Both Washington and Venezuela’s opposition are seeking to counter perceptions that their efforts to oust Maduro have stalled.
Though differences over Iran and Afghanistan policy were the main reasons for US President Donald Trump’s firing of his hawkish national security adviser John Bolton last week, Trump had also grown increasingly impatient with the failure of sanctions and diplomatic pressure to push Maduro from power.
Despite Trump’s vows that all options were on the table, he had resisted Bolton’s push for more military planning, according to a person familiar with the matter. Trump’s aides have made clear that he is likely to impose further sanctions but the economic weapons at Washington’s disposal appear to be dwindling.
US State Department spokeswoman Morgan Ortagus said in a statement on Tuesday that the United States continued to stand with Guaido and that sanctions “will not be lifted until Maduro is gone.”
“We look forward to coming together with regional partners to discuss the multilateral economic and political options we can employ to the threat to the security of the region that Maduro represents,” she said.
