“Here’s an interesting report that didn't make it into this issue of the Digest. Micro- and nanoplastics are ubiquitous environmental pollutants. Humans encounter these pollutants through ingestion, inhalation, and skin contact, eliciting various harmful health effects. This review summarizes the current knowledge of the effects of micro- and nanoplastic exposure.”

“PCB exposure may also be linked to neurodegenerative disease PCBs bioaccumulate in human muscle and adipose tissue, brain, liver, and lungs and have long elimination half-lives, ranging from 10 to 15 years.”

“These results and other similar studies suggest that it may be important to minimize exposure to air pollution during key brain developmental periods including pregnancy, infancy, and early childhood.”

“Another study found that for every 3.5 micrograms of PM2.5 per cubic meter of air, white matter (the myelinated region of the brain) decreased by 6 cubic centimeters. Air pollution has been declining steadily since the EPA promulgated new standards in 2012 and it is important to keep these regulations of air pollution in place.”

“A recent study found that certain household chemicals, widely used for personal hygiene, cleaning, and disinfecting, may pose an unexpected risk for cognitive decline** in older adults. Researchers analyzed data from a large cohort study of adults over 65.”

“Pollution from microplastics and heavy metals has increased markedly in aquatic ecosystems in recent years, especially in industrial wastewater and municipal sewage, where these contaminants often coexist at high levels.”

“These findings suggest that the exposome is critical in shaping health and longevity. While genes contribute to some diseases, environmental exposures throughout life greatly influence aging and survival. Air pollution is an exposome element contributing to disease and early death.”

“01:08:59 - Sulforaphane promotes urinary excretion of benzene and acrolein, compounds in air pollution. Study. 01:09:14 - Sulforaphane activates Phase II detoxification enzymes and deactivates Phase I biotransformation enzymes, which can convert compounds to carcinogens.”

“People exposed to fire smoke showed more signs of immune system activation, including higher levels of memory CD8-positive T cells and markers that indicate increased movement and activity of immune cells.”

Since sulforaphane’s discovery, countless studies have investigated its effects on many human diseases, including air pollution toxicity, asthma, autism[1][2], radiation dermatitis, schizophrenia, cancers of the bladder, breast, colon, lung, and prostate, and many others.
