Metal mixtures in cord blood linked with reduced birth size


Metal mixtures in cord blood linked with reduced birth size
Mixtures of toxic metals in umbilical cord blood were associated with reduced birth size, according to a new study led by researchers at Harvard T.H. Chan School of Public Health.
The study, which was published May 14, 2021, in Environmental Health Perspectives, analyzed data from a group of more than 1,000 pregnant women in Bangladesh who had been exposed to metals from multiple sources. The researchers looked the birth weight, birth length, and head circumference of the women’s newborns, and also measured the amounts of several metals arsenic, cadmium, manganese, and lead in umbilical cords. They found that higher levels of metal mixtures in the umbilical cords were significantly linked with smaller birth size. ....

Air pollution linked with increased risk of autism in children


Exposure to fine particulate air pollution (PM
2.5) has been linked with significantly increased risk of autism spectrum disorder (ASD) in children, particularly if exposure occurs during the third trimester of pregnancy or during early childhood, according to a meta-analysis from Harvard T.H. Chan School of Public Health.
The study was published April 29, 2021, in Environmental Research Letters.
The authors noted that there has been a steep rise in the prevalence of childhood diagnosis of ASD over the past several years, from 6.7 per 1,000 people in 2000 to 16.8 per 1,000 people in 2014. Possible risk factors include those related to family, such as genetics or parental age, or the environment. Previous studies have found an association between exposure to ambient particulate matter (PM) and neurobehavioral dysfunction. ....

Pop those 'BPA-free' drinking bottles into the dishwasher before using them

As part of a laboratory experiment, Rebecca Holmes examined water bottles that had been acquired from abroad expecting to find bisphenol A (BPA), a human-made component commonly found in polycarbonate plastics used to make consumer products.
What she found, however, was that those water bottles were just fine, yet some control bottles purchased in the United States and supposedly BPA-free actually contained traces of the chemical now thought to negatively impact heart health.
Holmes, a researcher formerly in the laboratory of Hong-Sheng Wang, PhD, professor in the University of Cincinnati Department of Pharmacology and Systems Physiology, was working on her master s degree in molecular, cellular and biochemical pharmacology in the College of Medicine at the time. ....
