Eczema is on the rise globally. At the same time, industrialization has increased, which has resulted in increases in air pollution (industrial practices generate air pollution). A recent study found an association of air pollution and eczema - the more air pollution rises, the greater the incidence of eczema. Researchers specifically looked at fine particulate ...continue reading "Eczema Associated With Air Pollution"
Something that makes sense, but developers will probably deny: The air in communities by large warehouses is more polluted than elsewhere, and this pollution can even be detected from satellites in space (satellite data)! Researchers examined nitrogen dioxide levels around 149,075 warehouses in the U.S. They found that communities with warehouses were exposed to an ...continue reading "Warehouses Increase Air Pollution In Nearby Communities"
Ever notice that deodorants, lotion, body spray, shampoo, and other personal care products can be smelled in the air long after they have been used? Well... this is because they leave behind a mixture (cocktail) of all sorts of chemicals in the air. Researchers found that a mixture of over 200 volatile organic compounds (VOCs) ...continue reading "Personal Care Products Are A Source of Indoor Air Pollution"
It has long been known that children living in congested cities have higher rates of asthma. All those vehicles, all that pollution. A recent study found that prenatal air pollution exposure is also important in asthma development. Pregnant women exposed to high levels of tiny ultra-fine particles (UFPs, <0.1 µm) in the air were more ...continue reading "Pregnancy and Air Pollution Linked to Asthma in the Children"
Air pollution is a killer, but it also does damage in subtle ways - such as having effects on the brain. A recent study found that early childhood exposure to high amounts of traffic-related air pollution (city life, living next to a highway) resulted in the brain having structural changes (differences in brain volume and cortical ...continue reading "What Is Air Pollution From Traffic Doing To Your Brain?"
A new study has nicely illustrated how extreme air pollution gets quickly into a person and has negative health effects, but improvement occurs when the exposure to the air pollution ends. It has long been known that long-term exposure to air pollution is associated with increased heart disease and death from heart disease (cardiovascular morbidity ...continue reading "Even Short-term Exposure to High Levels of Air Pollution Is Bad For Your Health"
Several recent studies have highlighted the negative effects of air pollution on the brain, specifically from the tiniest particles in polluted air (called PM 2.5). These tiny particles get to the human brain and cause all sorts of damage. Even at levels within government guidelines. Two studies found that with higher chronic (daily) exposure to PM2.5 ...continue reading "Air Pollution and the Brain, Part 1"
Two recent studies point out the dangers of air pollution to the developing fetus. The first study found an association with high levels of air pollution during pregnancy and lower IQ years later when the children were between the ages of 4 to 6 (as compared to women exposed to less traffic-related air pollution during ...continue reading "Air Pollution Has Harmful Effects During Pregnancy"
Researchers measured chemicals in the air in 2 cities (Boulder, CO and Toronto, Canada) and found equally high levels of 2 chemicals in the air during morning commute times - benzene (from vehicle exhaust) and a type of siloxane (from personal care products). What? This study's results make a strong case for reading ingredient lists of ...continue reading "Personal Care Products and Air Pollution"
Uh-oh, it looks like some (many?) new or fairly new kitchen cabinets are outgassing several types of PCBs from the wood sealants used on the cabinets. PCBs (polychlorinated biphenyls) were banned in the 1970s due to health risks - for example, they are known carcinogens, and some are neurotoxic (also here). Researchers from the University ...continue reading "Kitchen Cabinet Sealants Can Be A Source of Indoor Air Pollution"
