Top scientists sound alarm about dangerous chemicals in children’s toys, clothing

Over 350,000 chemicals, chemical mixtures and plastics used in common products like winter gloves, toys and electronics are contributing to soaring rates of diseases like diabetes and cancer in kids, as well as conditions like autism and ADHD, a consortium of prominent doctors and researchers have warned. 

In a January letter published in the prominent New England Journal of Medicine, about two dozen experts warned that the widespread use of synthetic chemicals in consumer goods is harming children. They called for stronger rules to force the testing and monitoring of new chemicals as they enter the market. But Canada and the U.S. only regulate a handful of these products and manufacturers can use most of them with impunity — even though the chemicals are routinely found in humans.

"Everyone in this group was alarmed by the concerning trends in children's health and the need for more attention to address this really important societal problem," said contributor Tracey Woodruff, an expert on reproductive health and the environment at the University of California, San Francisco. 

"We need much more comprehensive regulations if we're going to protect kids from the ways that they're being exposed now to these known and emerging harms," said Cassie Barker, toxics program director for Environmental Defense. "Parents shouldn't need to access a testing lab to know whether or not the products that they're buying for their kids are safe." 

Over the past 50 years, childhood cancers have increased by 35 per cent while male reproductive birth defects have become twice as frequent. Childhood asthma and obesity have increased three- and four-fold, respectively. About one in six kids has a neurodevelopmental disorder like ADHD or autism

Many of these conditions are linked to exposure to synthetic chemicals while in utero or as a very young child, with the impacts only becoming evident years or decades later. Yet regulations for chemicals — when regulations exist — typically don't take these long-term risks into account, the letter warns, with “almost no postmarketing surveillance for longer-term adverse health effects.” 

The problem is poised to worsen. Production of these chemicals is growing by about three per cent annually and is projected to triple by 2050 if nothing is done, exacerbating already widespread pollution and human exposure. 

That growth is entwined with the oil and gas industry, Woodruff explained. Many of the most harmful and ubiquitous chemicals — for instance PFAS, phthalates or bisphenol-A (BPA) — are made from fossil fuels and integrated into plastics. People are exposed to the chemicals when they use the products or ingest microplastics, which have become ubiquitous in food and water. 

As the world curbs its use of oil and gas for transportation, heating and electricity, fossil fuel producers are banking on increased demand for plastics and other petrochemicals. Determined to protect those profits, petrochemical companies have spent years aggressively lobbying against stricter rules on synthetic chemicals and plastics, Woodruff said. 

Over 350,000 chemicals, chemical mixtures and plastics used in common products like winter gloves, toys and electronics are contributing to soaring rates of diseases like diabetes and cancer in kids, along with autism and ADHD, researchers warn.

Regulations that target classes of chemicals, instead of individual products, are key because they prevent companies from replacing banned chemicals with new, slightly different but similarly harmful ones, she said. Canada has taken steps toward this approach: in 2023, federal officials proposed rules on PFAS, a family of grease- and water-resistant chemicals linked to cancer and other health risks. But last July, the government backtracked under industry pressure and excluded one of the largest categories of PFAS from its proposal. 

When asked about the consortium's warning, Health Canada representatives pointed Canada's National Observer to federal guidelines for toxic products in children's toys on a webpage that hasn’t been updated in three years. The rules restrict the amount of some phthalates in toys; how much lead they can contain; bans them from containing a handful of toxic substances; and prohibits substances like cadmium and arsenic in toy coatings. 

Still, Barker said those rules aren't proportionate to the scale and severity of the problem. 

"We've lost focus on the real threats to children and their health," she said. "We're in this era of talking about red tape [but] children's health isn't red tape."
