Germ-Killing Chemicals Used in 2,000+ Consumer Products Found in Pregnant Women, Newborns
Half of newborns in a Brooklyn-based study were exposed in the womb to triclosan, a germ-killing chemical widely used in consumer products, researchers reported Sunday at an annual meeting of chemists.
“Our study suggests that expectant mothers may be highly exposed to these compounds, which have endocrine-disrupting capabilities,” said study coauthor Laura Geer, an environmental health scientist at SUNY-Downstate Medical Center in New York.

In addition to triclosan, about one-quarter of the newborns were exposed to traces of triclocarban, another germ-killing chemical in some bar soaps.
The researchers also reported that pregnant women with higher levels of butylparaben, a cosmetics germ-killing preservative, gave birth to shorter babies than women with lower levels. It’s not clear what health effects, if any, the shorter lengths would have on a child, Geer said. Those findings are preliminary and have not yet been published, so Geer declined to reveal details on the length differences.
“Shifts in birth size may be an indication of endocrine disruption,” she said. “We hope to address the question of adverse health outcomes associated with these chemicals in future research.”
The findings are being presented at the American Chemical Society’s annual meeting in San Francisco. They add to growing debate about the safety of antimicrobial chemicals in consumer products. Triclosan and triclocarban are used in more than 2,000 items, including some toothpastes, liquid soaps, detergents, clothing and toys.
Last year, the U.S. Food and Drug Administration (FDA) announced that antibiotic hand soaps and body washes containing the two chemicals were no more effective than regular soap and water. The FDA is reviewing their safety and possible health effects, with a ruling expected in 2016. Earlier this year, Minnesota became the first state to ban triclosan in some household products.
Studies have reported that triclosan and triclocarban may add to the spread of antibiotic-resistant bacteria, disrupt development of the brain and reproductive system and accumulate in plants and animals. Parabens, identified as estrogen mimics, have been linked to reproductive problems in lab animals, as well as allergies and skin irritation.
In the Brooklyn study, all of the 184 pregnant women tested had traces of triclosan in their urine, while 86 percent had triclocarban, according to the study by Geer and Arizona State University researchers. Umbilical cord blood from 33 of the women was tested. It was the first time triclocarban had been studied in pregnant women and fetuses.
The women had higher levels of the chemicals, on average, than the general U.S. population. Most of the women tested were black.
“If you cut off the source of exposure, eventually triclosan and triclocarban would quickly be diluted out, but the truth is that we have universal use of these chemicals, and therefore also universal exposure,” Rolf Halden, the study’s lead investigator and director of Arizona State’s Center for Environmental Security, said in a statement.
Paul DeLeo, an associate vice president of the American Cleaning Institute, which represents the U.S. cleaning products industry, said the traces found are too small to have any effect.
“Everything around us gets into us. But the levels they are finding are extremely small. There’s a wide margin of safety between these levels and the levels deemed unsafe based on standard toxicology testing,” he said.
However, experts say that standard toxicological tests do not detect many effects, especially ones related to hormone disruption.
Geer said pregnant women who want to reduce their exposures should scan the active ingredients listed on the back of products. “Avoid products labeled ‘antimicrobial,’ since these products likely contain triclosan or triclocarban as active ingredients,” she said.
Big-name manufacturers Proctor & Gamble and Johnson & Johnson have announced they are phasing out triclosan from their products. Many cosmetics companies market paraben-free products.

Climate Week this year coincides with clear skies in Washington state for the first time in almost two weeks.
In just a few days in early September, Washington state saw enough acres burned – more than 600,000 – to reach our second-worst fire season on record. Our worst fire season came only five years ago. Wildfires aren't new to the west, but their scope and danger today is unlike anything firefighters have seen. People up and down the West Coast – young and old, in rural areas and in cities – were choking on smoke for days on end, trapped in their homes.
Fires like these are becoming the norm, not the exception.

To understand the planetary importance of this autumn's presidential election, check the calendar. Voting ends on November 3—and by a fluke of timing, on the morning of November 4 the United States is scheduled to pull out of the Paris Agreement.
President Trump announced that we would abrogate our Paris commitments during a Rose Garden speech in 2017. But under the terms of the accords, it takes three years to formalize the withdrawal. So on Election Day it won't be just Americans watching: The people of the world will see whether the country that has poured more carbon into the atmosphere than any other over the course of history will become the only country that refuses to cooperate in the one international effort to do something about the climate crisis.

Hamstrung by coronavirus lockdowns, frustrated school strikers have spent months staging digital protests against world leaders failing to act urgently on climate change.
Pandemic Stalls Protests<p>Last November, the head of the UN Environment Program was among the public and scientific figures to warn that 2020 offered a last chance to cut emissions. Then, few could have suspected this deadline would coincide with an unprecedented public health emergency.</p><p>The pandemic has <a href="https://www.dw.com/en/tough-times-ahead-for-climate-protesters-during-corona-pandemic/a-52978469" target="_blank">dealt climate activism a blow</a>. Niedeggen says that as a movement demanding that the world act on scientific advice, the school strikers took lockdown restrictions extremely seriously, halted public protests immediately and took their activism online.</p><p>On April 24, Fridays for Future organized a "digital strike," with Niedeggen hosting a that racked up close to a quarter of a million views. "We were not physically standing together, but we were all fighting together," she says.</p><p><a href="https://www.dw.com/en/climate-strikers-get-inventive-during-the-covid-19-crisis-fridays-for-future/a-53229262" target="_blank" rel="noopener noreferrer">Activists also gathered thousands of placards</a> from across Germany to lay out in front of the German Bundestag around the central slogan: "Fight every crisis."</p>
Opportunity for a New Normal<p>Last September's Global Climate Strike drew young and old protestors around the world, with organizers estimating a global turnout of 7.6 million, including an estimated 270,000 people in Berlin. Activists have adjusted this year's event to account for social distancing and different levels of coronavirus restrictions in cities taking part.</p><p>They say COVID-19 also presents opportunities.</p><p>"The pandemic shows that we can change our normal daily life, and we are very able to adjust to a situation of crisis," she says. The key question is how economies get back on their feet: "We have the possibility to build a new normal, to build a renewable world order, and an environmentally just, climate-just normal for everybody."</p><p>In July, Jeng was among 20 female Fridays for Future activists from the Global South to sign an open letter to G20 finance ministers warning that their decisions in "exclusive backrooms" over stimulus packages and corporate bailouts would "lock in development pathways for decades."</p><p>"The system is not broken, it was built to be unjust. We don't need recovery, we need a reboot," the letter reads, stressing that "black people, indigenous peoples and people of color," have been disproportionately hit by the economic, climate and coronavirus crises. </p>
Policy 'Not Quite There Yet'<p>Figures on stimulus spending do not suggest their words had much impact. The ministers were criticized for failing to relieve the debt of poorer countries, and according to <a href="https://www.energypolicytracker.org/region/g20/" target="_blank" rel="noopener noreferrer">Energy Policy Tracker</a>, G20 countries by August had pledged $169 billion (142 billion euros) to fossil fuels since the beginning of the pandemic.</p><p>Katrin Uba, associate professor of political science at Uppsala University in Sweden, is researching Fridays for Future. She says that despite the movement raising awareness and gaining access to policymakers, real policy change "is not there yet."</p><p>Still, she stresses that social movements go through waves of mobilization as public attention on their core issues ebbs and flows. And perhaps one of Fridays for Future's biggest achievements is birthing a politically active generation that will keep the fight up long after corona becomes a memory. </p><p>"We know clearly from our research that many of the people who came to the streets hadn't done any protesting before in their lives," she told DW. "And we also know that if you do one protest, you are likely to do more."</p>
