Popular Fireworks Emit High Levels of Lead and Toxins

Fireworks have taken a lot of heat recently. In South Dakota, fire experts have said President Trump's plan to hold a fireworks show is dangerous and public health experts have criticized the lack of plans to enforce mask wearing or social distancing. Now, a new study shows that shooting off fireworks at home may expose you and your family to dangerous levels of lead, copper and other toxins.
The study, published Wednesday in the journal Particle and Fibre Technology, analyzed 12 different retail fireworks and found that once set off, five of them released particle emissions that could damage human cells and animal lungs, as CNN reported.
The metals are used to give the fireworks their vibrant colors when they explode. However, those same metals are hazardous to humans and animals. The study said that blue fireworks can be made of copper and red fireworks can contain strontium, which gives a brilliant red light.
"While many are careful to protect themselves from injury from explosions, our results suggest that inhaling firework smoke may cause longer-term damage, a risk that has been largely ignored," said Terry Gordon, environmental medicine professor at New York University's Grossman School of Medicine, as the New York Daily News reported
The study acknowledged that people are typically exposed to these emissions a few times a year, usually around July 4th and New Year's Eve. And yet, even that exposure means people are inhaling much more harmful toxins than what people breathe in normally.
The researchers looked at 14 years of air quality samples taken at dozens of locations across the U.S. by the Environmental Protection Agency throughout the years. The researchers noticed that levels of toxic metals tended to peak in samples taken near Independence Day and New Year's Eve celebrations. The concentration of airborne toxic metals was much higher during those years than at any other time.
"Although people are only exposed to these substances for a short time each year, they are much more toxic than the pollutants we breathe every day," said Dr. Gordon in an NYU press release.
"I could hypothesize that people could have, especially susceptible people like asthmatics, increased episodes," Gordon said to CNN.
To conduct the study, the scientists detonated fireworks in a laboratory chamber. They tested roughly a dozen types of fireworks commonly sold in the U.S., including the Black Cuckoo, the Color-Changing Wheel and the Blue Storm firecracker. They then tested mice and human lung cells with the captured particles.
The Black Cuckoo, a fountain-style firework, registered the most toxic of the group, at 10 times more damaging to human cells than a nontoxic saline solution, according to the findings, as NYU said in a statement.
Gordon said that the firework emitted lead particles at 40,000 parts per million, which is exceedingly high. Normally, lead should not be emitted at all, he said, as CNN reported.
Families looking to set off fireworks this weekend should be particularly mindful of children's developing lungs and brains. Parents should make sure their kids are far away from the fireworks smoke and any potential lead exposure.
"Allow the adults to be the ones to set off the fireworks and stay upwind from it so that the smoke is blowing in the breeze," said Kristin Van Hook, chair of the American Academy of Pediatrics section on pediatric pulmonology and sleep medicine.
She told CNN she has seen cases where children who have asthma breathed in fumes from fireworks and ended up in the emergency room.
Gordon also said that families should be aware what their children are exposed to and that everyone should try to stay downwind from fireworks. He added that the fireworks industry must increase its safety regulations.
"Given what we've found, I propose that ... they make sure they are importing safer fireworks and that that's what the consumers use," Gordon said to CNN.

At first glance, you wouldn't think avocados and almonds could harm bees; but a closer look at how these popular crops are produced reveals their potentially detrimental effect on pollinators.
Migratory beekeeping involves trucking millions of bees across the U.S. to pollinate different crops, including avocados and almonds. Timothy Paule II / Pexels / CC0<p>According to <a href="https://www.fromthegrapevine.com/israeli-kitchen/beekeeping-how-to-keep-bees" target="_blank">From the Grapevine</a>, American avocados also fully depend on bees' pollination to produce fruit, so farmers have turned to migratory beekeeping as well to fill the void left by wild populations.</p><p>U.S. farmers have become reliant upon the practice, but migratory beekeeping has been called exploitative and harmful to bees. <a href="https://www.cnn.com/2019/05/10/health/avocado-almond-vegan-partner/index.html" target="_blank">CNN</a> reported that commercial beekeeping may injure or kill bees and that transporting them to pollinate crops appears to negatively affect their health and lifespan. Because the honeybees are forced to gather pollen and nectar from a single, monoculture crop — the one they've been brought in to pollinate — they are deprived of their normal diet, which is more diverse and nourishing as it's comprised of a variety of pollens and nectars, Scientific American reported.</p><p>Scientific American added how getting shuttled from crop to crop and field to field across the country boomerangs the bees between feast and famine, especially once the blooms they were brought in to fertilize end.</p><p>Plus, the artificial mass influx of bees guarantees spreading viruses, mites and fungi between the insects as they collide in midair and crawl over each other in their hives, Scientific American reported. According to CNN, some researchers argue that this explains why so many bees die each winter, and even why entire hives suddenly die off in a phenomenon called colony collapse disorder.</p>

Many have opted to salvage what partial colonies survive and move away from agricultural areas.</p><p>The future of pollinators and the crops they help create is uncertain. According to the United Nations, nearly half of insect pollinators, particularly bees and butterflies, risk global extinction, Phys.org reported. Their decline already has cascading consequences for the economy and beyond. Roughly 1.4 billion jobs and three-quarters of all crops around the world depend on bees and other pollinators for free fertilization services worth billions of dollars, Phys.org noted. Losing wild and native bees could <a href="https://www.ecowatch.com/wild-bees-crop-shortage-2646849232.html" target="_self">trigger food security issues</a>.</p><p>Salazar, the beekeeper, warned Phys.org, "The bee is a bioindicator. If bees are dying, what other insects beneficial to the environment... are dying?"</p>

Australia is one of the most biodiverse countries in the world. It is home to more than 7% of all the world's plant and animal species, many of which are endemic. One such species, the Pharohylaeus lactiferus bee, was recently rediscovered after spending nearly 100 years out of sight from humans.
Scientists have newly photographed three species of shark that can glow in the dark, according to a study published in Frontiers in Marine Science last month.
