The prestigious medical journal The Lancet recently released a report by its Commission On Pollution and Health on the effects of various types of pollution (water, air, occupational, chemical, etc) on people and world economies - that is, the effect of pollution on "global health". The main finding: Diseases caused by pollution were responsible in 2015 for ...continue reading "Pollution and Early Death"
A study of 60 million Americans 65 years old and older (the entire Medicare population) found that long-term exposure to airborne fine particulate matter (PM2.5) and ozone at concentrations below current national standards increases the risk of premature death ("all cause mortality") even when the levels are below current national standards. This effect was most pronounced ...continue reading "Older Adults, Air Pollution, and Premature Death"
Nowadays there is tremendous concern about the spread of antibiotic resistant bacteria or "superbugs" throughout the world. Articles frequently mention India being at the epicenter of this crisis - that is, the source of many antibiotic resistant strains (both in and out of hospitals), which then travel throughout the world due to global travel. The ...continue reading "Big Pharma’s Pollution Leading To Superbugs"
This post is more on the theme of nanoparticles and human health. My last post was about a study that examined how inhaled nanoparticles (for example, from air pollution) travel from the lungs to the bloodstream. Well, today's post is about a pretty shocking 2016 air pollution nanoparticle study which examined the brains (brain tissue) of ...continue reading "Pollution Nanoparticles Found in Human Brains"
The use of nanomaterials has been really increasing in recent years without us really understanding if nanoparticles have negative health effects, and if they travel to the brain or other organs in the human body. Nanoparticles are used in many consumer products, including foods (e.g., nano-sized titanium dioxide) and medicines, but they are also found ...continue reading "Nanoparticles in Air Pollution Travel From Lungs to Bloodstream?"
Another study finding a link between air pollution and negative health effects - this time a higher incidence of decline in cognitive functioning and dementia in older women (65 and older) exposed to fine particles (PM2.5 ). These extremely small particles from vehicle emissions are a major source of urban air pollution throughout the world. ...continue reading "Air Pollution, the Aging Brain, and Dementia"
Study after study finds negative health effects from air pollution, such as heart disease (here, here, and here). Now two more studies found that living in areas with high air pollution is linked to a higher stroke risk. One study (done in Japan) found an increase of ischemic stroke on the same day as exposure ...continue reading "Air Pollution Linked To Strokes"
An new analysis of published studies found that air pollution is linked to high blood pressure. Yes, breathing polluted air has health effects (here, here, and here). From Science Daily: High blood pressure linked to short-, long-term exposure to some air pollutants Both short- and long-term exposure to some air pollutants commonly associated with coal ...continue reading "Air Pollution Linked to High Blood Pressure"
Last fall a study came out that estimated that annually about 3.3 million deaths throughout the world were caused from air pollution. But a study was presented Friday at the American Association for the Advancement of Science (AAAS) that gave a much higher estimate of annual air pollution deaths: 5.5 million. A horrifying number. And ...continue reading "Annual Worldwide Deaths From Air Pollution"
A recent post (Air Pollution Can Kill You) discussed recent research that found that air pollution is linked to an overall increase in death rates, especially cardiovascular disease. But how many deaths each year are linked to air pollution? Recent research suggests that outdoor air pollution, mostly by fine particulate matter with a diameter smaller than ...continue reading "Millions of Deaths Annually Due to Air Pollution?"
