Lead Poisoning Affects One in Three Children Worldwide

Childhood lead poisoning is a long-recognized health hazard that has severely negative consequences for the developing brain. A new first-of-its-kind study reveals that lead poisoning is a global problem, affecting far more children than previously thought. The researchers estimate that roughly 800 million children worldwide, or one out of three, suffer from lead poisoning, according to The New York Times.

Children with a blood lead level above 5 micrograms per deciliter need immediate treatment to prevent life-long consequences from the powerful neurotoxin. The report, The Toxic Truth: Children's exposure to lead pollution undermines a generation of potential, says that the bulk of affected children live in South Asia. India is one of the worst affected countries, where more than 275 million children have dangerously high lead levels in their blood, the BBC reported.

The study is a collaboration between UNICEF and Pure Earth, a nonprofit that seeks to help poor countries threatened by toxic pollutants.

"With few early symptoms, lead silently wreaks havoc on children's health and development, with possibly fatal consequences," said UNICEF Executive Director Henrietta Fore in a UN statement. "Knowing how widespread lead pollution is – and understanding the destruction it causes to individual lives and communities – must inspire urgent action to protect children once and for all."

Childhood lead exposure has been linked to behavioral problems. It can also eventually lead to kidney damage and cardiovascular conditions, according to Agence-France Presse (AFP). Lead poisoning is estimated to cost low- and middle-income countries almost $1 trillion over children's lifetimes, AFP reported.

The study showed lead poisoning is a major problem in developing South Asian countries since environmental safeguards have not yet been put in place or are poorly enforced. That means that lead in dust and fumes from smelters, fires, car batteries, old peeling paint and water pipes, electronics junkyards, and even cosmetics and lead-infused spices pose an enormous risk to the mental and physical development of a generation of children, The New York Times reported.

"The unequivocal conclusion of this research is that children around the world are being poisoned by lead on a massive and previously unrecognized scale," the study found.

The study also discovered that nearly one million adults die prematurely every year because of lead exposure.

The report's authors say that vehicle batteries are the prime culprit of lead exposure. They based their findings on data from the Institute of Health Metrics and Evaluation (IHME) at the University of Washington, which obtained blood test results from tens of thousands of children around the world, the BBC reported.

"Vehicles in low and middle-income countries have tripled since 2000 and that has led to a graphic rise in lead acid battery recycling, often in an unsafe way," Dr. Nicholas Rees, one of the report's authors, told the BBC.

The BBC reported that about 85 percent of the world's lead goes into producing lead-acid batteries, with the vast majority coming from recycled car batteries.

"As a result, as much as half of the used lead-acid batteries end up in the informal economy," the report found, according to the BBC. "Unregulated and often illegal recycling operations break open battery cases, spilling acid and lead dust onto the ground, and [there is] smelt lead in open-air furnaces that spew toxic fumes and dust that contaminate surrounding neighborhoods."

However, lead poisoning is rare in more developed countries, suggesting that the problem is solvable with decisive action.

"The good news is that lead can be recycled safely without exposing workers, their children and surrounding neighborhoods," said Richard Fuller, president of Pure Earth, the AFP reported. "People can be educated about the dangers of lead and empowered to protect themselves and their children."

He added that the economic and social returns in reducing lead pollution could be enormous.

"Improved health, increased productivity, higher IQs, less violence, and brighter futures for millions of children across the planet," said Fuller, according to the AFP.

In early October, Britain's Prince William teamed up with conservationist David Attenborough to launch the Earthshot Prize, a new award for environmentalist innovation. The Earthshot brands itself the "most prestigious global environment prize in history."

The world-famous wildlife broadcaster and his royal sidekick appear to have played an active role in the prize's inception, and media coverage has focused largely on them as the faces of the campaign.

But the pair are only the frontmen of a much larger movement which has been in development for several years. In addition to a panel of experts who will decide on the winners, the prize's formation took advice from the World Wildlife Fund, Greenpeace and the Jack Ma Foundation.

With more and more global attention on the climate crisis, celebrity endorsement of environmental causes has become more common. But why do environmental causes recruit famous faces for their campaigns? And what difference can it make?

'Count Me In'

"We need celebrities to reach those people who we cannot reach ourselves," says Sarah Marchildon from the United Nations Climate Change secretariat (UNFCCC) in Bonn, Germany.

Marchildon is a proponent of the use of celebrities to raise awareness of environmental causes. In addition to promoting a selection of climate ambassadors who represent the UN on sustainability issues, Marchildon's team has produced videos with well-known narrators from the entertainment world: among them, Morgan Freeman and Mark Ruffalo.

"We choose celebrities who have a lifestyle where they are already talking about these issues," Marchildon explains.

"Sometimes they reach out to us themselves, as David Attenborough did recently. And then they can promote the videos on their own social channels which reach more people than we do — for example, if they have 20 million followers and we have 750,000."

Environmental groups focused on their own domestic markets are also taking this approach. One Germany-based organization that uses celebrities in campaigns is the German Zero NGO. Set up in 2019, it advocates for a climate-neutral Germany by 2035.

German Zero produced a video in March 2020 introducing the campaign with "66 celebrities" that supported the campaign, among them Deutschland 83 actor Jonas Nay and former professional footballer Andre Schürrle. They solicit support as well as financial contributions from viewers.

"Count me in," they say, pointing toward the camera. "You too?"

"We are incredibly grateful for the VIPs in our videos," says German Zero spokeswoman Eva-Maria McCormack.

Assessing Success Is Complex

But quantifying the effectiveness of celebrity endorsement of campaigns is not a straightforward process.

"In order to measure effectiveness, first of all you need to define what is meant by success," says Alegria Olmedo, a researcher at the Zoology Department at the University of Oxford.

Olmedo is the author of a study looking at a range of campaigns concerning pangolin consumption, fronted by local and Western celebrities, in Vietnam and China. But she says her biggest stumbling block was knowing how to measure a campaign's success.

"You need a clear theory of change," explains Olmedo. "Have the celebrities actually helped in achieving the campaign's goals? And how do you quantify these goals? Maybe it is increased donations or higher engagement with a cause."

A popular campaign in China in recent years saw famous chefs Zhao Danian and Shu Yi pledge to abstain from cooking endangered wildlife. While the pledge achieved widespread recognition, both Olmedo and Marchildon say it's difficult to know whether it made any difference to people's actions.

"In life we see a thousand messages every day, and it is very hard to pinpoint whether one campaign has actually made a difference in people's behavior," she explains.

Awareness Is Not Enough

Many campaigns that feature celebrities focus on raising awareness rather than on concrete action — which, for researcher Olmedo, raises a further problem in identifying effectiveness.

"Reach should never be a success outcome," she says. "Many campaigns say they reached a certain number of people on social media. But there has been a lot of research that shows that simply giving people information does not mean they are actually going to remember it or act upon it."

But anecdotal evidence from campaigns may suggest reach can make an active difference.

"Our VIP video is by far the most watched on our social media channels," McCormack from German Zero says. "People respond to it very directly. A lot of volunteers of all ages heard about us through that video."

However, some marketing studies have shown that celebrity endorsement of a cause or product can distract from the issue itself, as people only remember the person, not the content of what they were saying.

Choosing the Right Celebrity

Celebrity choice is also very important. Campaigns that use famous faces are often aiming to appeal to members of the public who do not necessarily follow green issues.

For certain campaigns with clear target audiences, choosing a climate scientist or well-known environmentalist rather than a celebrity could be more appealing — Attenborough is a classic example. For others, images and videos involving cute animals may be more likely to get a message heard than attaching a famous face.

"We choose celebrities who have a lifestyle where they are already talking about these issues," says Marchildon from the UN. "You need figures with credibility."

McCormack cites the example of Katharine Hayhoe, an environmental scientist who is also an evangelical Christian. In the southern United States, Hayhoe has become a celebrity in her own right, appealing to an audience that might not normally be interested in the messages of climate scientists.

But as soon as you get a celebrity involved, campaigns also put themselves at risk of the whims of that celebrity. Prince William and younger members of the royal family have come under fire in recent years for alleged hypocrisy for their backing of environmental campaigns while simultaneously using private jets to fly around the world.

But Does It Really Work?

While environmental campaigns hope that endorsement from well-known figures can boost a campaign, there is little research to back this up.

"The biggest finding [from my study] was that we were unable to produce any evidence that shows that celebrity endorsement of environmental causes makes any difference," says Olmedo.

This will come as a blow to many campaigns that have invested time and effort into relationships with celebrity ambassadors. But for many, the personal message that many celebrities offer in videos like that produced by German Zero and campaigns like the Earthshot Prize are what counts.

The research may not prove this conclusively — but if the public believes a person they respect deeply personally cares about an important issue, they are perhaps more likely to care too.

"I personally believe in the power this can have," says Marchildon. "And if having a celebrity involved can get a single 16-year-old future leader thinking about environmentalist issues — that is enough."
