When it comes to exposure to hazardous chemicals, children are not just little adults. “Children are more vulnerable to environmental hazards,” states the Pediatric Environmental Health Specialty Unit, a subcommittee of the American Pediatric Society. “They eat, drink and breathe more than adults on a pound for pound basis.” This means children are proportionally more exposed to toxins in air, water and food.
In areas of unconventional gas development, children are exposed to multiple industrial toxins, through air, and potentially through water and soil. Yet children’s health remains one of the many unexamined issues of this contentious industry.
Shale gas development creates a widespread network of open-air industrial sites. Well pads can be located close to rural and urban communities. In Pennsylvania, more than 3,000 gas fracking wells and permitted well sites were identified within two miles of 320 day care centers, 67 schools and nine hospitals and the industry was still growing.
Not only are children proportionally more exposed to toxins, children’s immature bodies are less able to metabolize some toxic substances. This means children are more vulnerable when they are exposed. Young children and babies in the womb are especially vulnerable. In these early stages, children go through critical periods of development when even small exposures to toxins can result in serious, lifelong harm.
In Pavillion, Wyoming, a three-year U.S. Environmental Protection Agency (EPA) study documented that 10 chemicals used in fracking were present in the town’s aquifer. Those chemicals included benzene at 50 times the level considered safe, as well as phenols, naphthalene and traces of diesel fuel–all of which are carcinogens. Other toxic chemicals including toluene, a nervous system toxin, were also found.
In situations where drinking water becomes contaminated, children are particularly vulnerable. New studies are indicating that water contamination from unconventional gas operations involving fracking may take place through a variety of routes, over a period of many years. The American Academy of Pediatrics “recommends that families with private drinking water wells in NGE/HF [natural gas extraction/hydraulic fracturing] areas should consider testing the wells before drilling begins and on a regular basis thereafter for chloride, sodium, barium, strontium and VOCs…”
Children are also at risk from exposure to airborne toxins generated at many stages of shale gas extraction–including drilling, fracking, leaks from condensate tanks and pipelines, wastewater ponds and the ever-present 18-wheelers.
Benzene is one of the air pollutants frequently found in areas with shale gas development. It is released from flaring gas wells, condensate tanks and wastewater storage ponds. Benzene is a known carcinogen. Exposure to benzene during pregnancy has been shown to increase rates of childhood leukemia.
In Dish, Texas, air sampling found benzene at levels up to 55 times higher than allowable safety levels. In Colorado and New Mexico, citizen air sampling documented high concentrations of benzene in four of nine air samples, according to Gassed: Citizen Investigation of Toxic Air Pollution from Natural Gas Development. Benzene was found at levels 48.5 to 800 times higher than the U.S. EPA level used to estimate increased cancer risk from long-term exposure. One sample was collected outside an elementary school in Durango, Colorado. Benzene is also a blood and nervous system toxin.
The Gassed study also measured acrylonitrile, a carcinogen, in five of nine samples, ranging from 790 to 3000 times above the U.S. EPA level for increased cancer risk from long term exposure. All levels corresponded to what the EPA would consider an “unacceptable cancer risk." Acrylonitrile is also a respiratory toxin.
Shale itself contains toxins–including benzene, radioactive elements such as radium 226 with a half life of 1600 years, and heavy metals, including lead, uranium and arsenic. Fracking releases toxins from the shale, generating millions of gallons of newly toxic and radioactive wastewater as well as tons of toxic and radioactive sand and mud. These waste products often remain in open ponds or piles for years, releasing volatile compounds into air, and with the potential of leaching water-soluble toxins into surrounding soil and waterways. Each of these toxins poses risks to children’s development and health.
Waste ponds also contain fracking chemicals, which return to the surface with the waste water. The chemicals used in fracking fluids include respiratory toxins, carcinogens, immune system toxins and endocrine disruptors. Endocrine disruptors are of particular concern to children’s health. Infants, children and developing fetuses are the most vulnerable to exposure to endocrine disrupting chemicals. Exposure at these critical stages of development can affect fetal growth, reproductive tract development, pubertal development, neurodevelopment and obesity. Research from Dr. Theo Colborn indicates that 40 percent of chemicals in fracking fluids are endocrine disruptors, both volatile and water-soluble.
Heavy truck traffic–estimated at 2,400 truck trips per frack per well–as well as drill pad machinery generate large quantities of diesel fuel combustion products. Diesel combustion products have multiple health impacts. Pre-natal exposure to diesel fuel combustion products is a known risk for low birth weight. Low birth weight is a major indicator of child health, and is associated with multiple health and learning issues throughout life.
Asthma is the most common chronic disease of childhood, and diesel combustion products are linked to increased asthma attacks. Another contributor to increased asthma is increased ozone. Rural areas in Wyoming and Utah with intensive gas drilling have measured ozone levels higher than the worst days in smoggy Los Angeles. Gas drilling areas of Colorado, Texas, Wyoming and Utah have all recorded ozone levels exceeding federal health standards. The Utah Bureau of Land Management identified concentrated natural gas and oil development in the Uintah Basin as the primary cause of the ozone pollution in that area.
In Texas, the hospital serving the six intensively drilled counties in the state recorded asthma rates three times the state average. “It seems highly likely there will be impacts on children with asthma that lead to hospitalizations, lost school days and higher health care costs,” wrote the American Lung Association in a submission to New York’s review of hydraulic fracturing.
Ozone can also increase cancer risks. “Ozone is not a carcinogen per se, but animal studies show that, because it creates inflammation, it can raise the risk for metastases,” notes Dr. Sandra Steingraber.
There are few studies, and no hard answers, to determine exactly how much risk there is to children or adult health from shale gas development, but the risks appear considerable. A 2012 peer-reviewed study by researchers at the Colorado School of Public Health, found that residents living within half a mile of a gas well faced 66 percent greater cancer risks than residents living farther away. They also found a 150 percent increase in non-cancer risks, including neurological, respiratory and developmental impacts.
Children’s environmental exposures are becoming increasingly recognized as potential contributors to a range of diseases. “We know now that children may have genetic vulnerabilities for such conditions as autism, brain cancers and other chronic diseases, but that environmental insults can trigger the onset or progression,” says pediatric neurologist Dr Maya Shetreat-Klein, assistant clinical professor of Neurology at Albert Einstein College of Medicine.
Noise pollution may seem like a minor impact, but noise from drilling 24/7 is an additional risk to children’s health and ability to learn. The World Health Organization labels noise pollution “not only an environmental nuisance, but also a threat to public health.” Noise pollution has also been shown to negatively affect academic performance.
Environmental exposures are involuntary exposures. Parents living in an area with shale gas development cannot protect their children from exposure to multiple airborne toxins, or from other exposures stemming from the industry.
The New Brunswick College of Family Physicians is the first major health organization in Canada to call for a moratorium on shale gas development and fracking, “until further research can prove that the benefits clearly outweigh the risks.”(9)
Medical staff at Sackville Memorial Hospital supported the College’s call for a moratorium, noting, “We believe that the health of children including the unborn may be especially at risk. We believe that adequate health studies do not yet exist to fully understand the health risks of this industry and that more studies are needed.”(10)
Health professionals in the US urge caution. “First do no harm,” wrote Dr. Madelon Finkel, in the American Journal of Public Health. “If you have an industry where there are, in a sense, known dangers, don’t go forward until you’ve actually analyzed and assessed what these dangers are.”(11)
Health is not just a matter of percentages and statistics. It’s also a matter of the heart. Environmental biologist and mother, Sandra Steingraber, author of Raising Elijah, is an eloquent advocate for the need to ban fracking for unconventional gas in New York State and elsewhere:
“… the bodies of my children are the rearranged molecules of the air, water, and food streaming through them. As their mother, there is no more important investment that I could make right now than to support the fight for the integrity of the ecological system that makes their lives possible.”(12)

Jean-Marc Neveu and Olivier Civil never expected to find themselves battling against disposable mask pollution.
When they founded their recycling start-up Plaxtil in 2017, it was textile waste they set their sights on. The project developed a process that turned fabrics into a new recyclable material they describe as "ecological plastic."
Mounting Piles of Waste<p>It is not only the streets of Chatellerault where pandemic pollution is piling-up, but also the world's beaches and oceans. Once there, they can take up to 450 years to degrade and disappear.</p><p>Esther Röling, co-organizer of the annual Adventure Clean Up Challenge held on Hong Kong Island, has seen this waste firsthand. In October the sports challenge pitted teams against one another in a competition to remove trash from 13 hard-to-reach coastal areas around the city.</p><p>They find tons of both disposable and reusable masks, said Röling. "You wonder how it ended up there. Was it just thrown on the ground? Or was it in a garbage bag that broke open?"</p><p>Almost 10,000 kilometers away in Antibes on the sunny French Riviera, it's a similar picture. For the past few months, divers and clean-up volunteers working with an ocean clean-up non-profit called Operation Mer Propre have been collecting an increasing number of masks found on land and in the sea.</p><p>"Since the beginning of the lockdown when we started to count, we've reached 800, 900, [and now in total] 1000 masks," said co-founder Joko Peltier. </p><p>According to <a href="https://unctad.org/news/growing-plastic-pollution-wake-covid-19-how-trade-policy-can-help" target="_blank">UN estimates</a>, up to 75% of all coronavirus-related plastic could end up as waste in oceans and landfills.</p>
The Limits of Recycling<p>Yet not all are convinced the recycling of this waste is possible on a global scale. </p><p>"What those citizen groups are doing is really beneficial but once they collect it, it should just go to a landfill or an incinerator. They shouldn't necessarily expect it to get recycled," said Jonathan Krones, an industrial ecologist and visiting assistant professor of environmental studies at Boston College.</p><p>That's because mask recycling programs like Plaxtil are few and far between and most don't have the benefit of a readily adaptable production process. </p><p>Even in countries with solid recycling infrastructure, he says, the system is designed to separate out specific types of waste like bottles or cardboard.</p><p>"I imagine that it would be technically feasible to develop a separation process to filter out masks, but there simply aren't enough of them to make that economical," he said.</p><p>Collection is a big hurdle, he adds. Since each mask only weighs a fraction of a gram and they're scattered on roads or mixed with other trash, it is difficult and costly. </p><p>"You need a lot of raw material of the right quality to make investing in the recycling technology and the recycling system worthwhile," he said.<span></span><br></p>
Hemp, Sugar Cane and Sustainable Alternatives<p>Some projects are instead addressing the material used to make masks.</p><p>French company Geochanvre have created a mask made primarily from hemp, while in Australia, researchers at the Queensland University of Technology are experimenting with a disposable product made from agricultural waste. </p><p>Biodegradable options are exciting alternatives to reduce the fossil fuels needed for the creation of plastic-based masks, said Krones, but they don't absolve the wearer from the responsibility of what happens afterwards. </p><p>Bio-based masks often need their own composing solutions, he explains, because in landfill they can produce high amounts of the greenhouse gas methane when anaerobic bacteria feeds on the organic material. Methane is known to be significantly more potent than carbon dioxide.</p><p>"I think as long as we have in our mind that we want to have disposability, we're going to have to wrestle with a variety of different sorts of environmental tradeoffs," he said, adding that reusable, fabric masks are the best option available to most people.</p><p>Precimask is developing a clear face covering with an optional visor made from hard plastic, designed to be long-lasting.<br></p><p>Air enters either side of the cheeks through a technology normally found in pool filters and car exhaust systems, said company spokeswoman Juliette Chambet.</p><p>"We wanted to make ceramic-based filters that would be washable and cleanable, which would allow them to be reused as many times as desired without having to buy a new consumable or produce waste," she said. </p><p>Ultimately, encouraging mask wearers to think about the entire lifecycle of a mask is key, explains Neveu. </p><p>"We want people who put on the masks to realize that they are also responsible for the waste, he said. "It's not inevitable that this [pandemic] will become an environmental catastrophe.</p><p><em>Reposted with permission from </em><em><a href="https://www.dw.com/en/covid-19-recycling-pollution-trash-pandemic/a-55707817" target="_blank">Deutsche Welle</a>.</em><a href="https://www.ecowatch.com/r/entryeditor/2649032193#/" target="_self"></a></p>
