Chemicals in consumer products linked to lower IQs in children
Scientists find common chemicals can negatively impact pregnant women.
- Researchers find a link between the use of chemicals by pregnant women and lower IQs in children by age 7.
- The scientists looked at chemical exposure in women in the first trimester of pregnancy.
- The issue particularly affects boys.
Researchers found that exposure to certain chemicals in consumer products during the first trimester of pregnancy is linked to lower IQ in children by age 7. Among the first of its kind, the study, carried out by scientists from the Icahn School of Medicine at Mount Sinai and Karlstad University, Sweden, linked mixtures of suspected endocrine-disrupting chemicals to prenatal neurodevelopment.
The research analyzed data from SELMA, a study of Swedish mothers and children during the first trimester of pregnancy, measuring 26 chemicals in the blood and urine of 718 mothers. The chemicals included bisphenol A (BPA), commonly found in plastic food and drink containers, as well as pesticides, phthalates, and others. Some of the 26 are established to affect the endocrine (hormone) activity while others are suspected to do so.
The scientists revisited the families when children reached age 7, finding that the kids whose mothers had greater amounts of chemicals in their system while pregnant exhibited lower IQ scores. This particularly affected boys, whose scores were two points lower. From all the chemicals, the greatest contribution to lower IQ was found to be from the compound bisphenol F (BPF), a BPA-replacement.

Other potentially harmful chemicals included the pesticide chloropyrifos, polyfluoroalkyl substances from cleaning products, triclosan, found in antibacterial soaps, soft polyvinyl chloride plastics and phthalates, which are used in cosmetics as well as numerous other products like soaps, nail polish, hairspray, shower curtains, raincoats, car interiors and even dryer sheets, as reported Scientific American.
Many of the chemicals only stay in the body for a short period of time, indicating that even being exposed to them briefly can have a negative effect. Previous studies linked endocrine disruptors to neurodevelopmental issues in children.
Eva Tanner, PhD, MPH, a postdoctoral researcher in the Department of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai, put their study in perspective —
"This study is significant because most studies evaluate one chemical at a time; however, humans are exposed to many chemicals at the same time, and multiple exposures may be harmful even when each individual chemical is at a low level," said Tanner.
Why ‘mom guilt’ is an unreasonable term
Professor Carl-Gustaf Bornehag of Karlstad University reiterated that being exposed to chemical mixtures in regular consumer products can affect the developing brains of children. Even chemicals that are supposed to be safer, like BPF, are not likely any better.
The scientists call for more research to confirm and expand upon their findings.

Construction of the $500 billion dollar tech city-state of the future is moving ahead.
- The futuristic megacity Neom is being built in Saudi Arabia.
- The city will be fully automated, leading in health, education and quality of life.
- It will feature an artificial moon, cloud seeding, robotic gladiators and flying taxis.
The Red Sea area where Neom will be built:

Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

Building a personal connection with students can counteract some negative side effects of remote learning.
- Not being able to engage with students in-person due to the pandemic has presented several new challenges for educators, both technical and social. Digital tools have changed the way we all think about learning, but George Couros argues that more needs to be done to make up for what has been lost during "emergency remote teaching."
- One interesting way he has seen to bridge that gap and strengthen teacher-student and student-student relationships is through an event called Identity Day. Giving students the opportunity to share something they are passionate about makes them feel more connected and gets them involved in their education.
- "My hope is that we take these skills and these abilities we're developing through this process and we actually become so much better for our kids when we get back to our face-to-face setting," Couros says. He adds that while no one can predict the future, we can all do our part to adapt to it.
Chronic irregular sleep in children was associated with psychotic experiences in adolescence, according to a recent study out of the University of Birmingham's School of Psychology.
