Why We Should Not Be Complacent About Lead Exposure

We poisoned ourselves with lead during the 20th century in most industrial nations. We used the metal widely, because lead paint is durable, engines run better on leaded gasoline and lead water pipes don’t rust.

Anxiety caused by exposure to pollution may make people more prone to cheating and unethical behavior, according to new research. And that can be a driver behind the higher crime rates in high-pollution areas.

The search for autism’s causes is a daunting task — but researchers are investigating a variety of factors that might play a role.

Theresa May’s new environment plan sets ambitious goals for plastic waste reduction. But there’s lots of room for slippage. One goal is to eradicate all “avoidable” plastic waste, though it’s not clear how “avoidable” will be defined.

A common herbicide is ending up in our food, thanks to the growing practice of using it to dry crops in preparation for harvest. In addition to speeding crop drying, glyphosate can help synchronize ripening in plants at harvest time.

Humans have built high-rises since ancient Roman times, but it wasn’t until the 20th century that they became the default work space for a significant slice of the world’s workers. While these buildings are certainly efficient, they can cause real health issues.

Runoff from melting snow carries road salt into streams and lakes, and causes extraordinarily high salinity.

Antibiotics are losing their ability to kill bacteria. One of the main reasons for the rise in antibiotic resistance is the improper use of antibiotics, but our latest research shows that the ingredients in commonly-used weed killers like Round-up and Kamba can also cause bacteria to become less susceptible to antibiotics.

Infectious diseases are spreading faster due to warmer temperatures, hunger and malnourishment is worsening, allergy seasons are getting longer and sometimes it’s simply too hot for farmers to tend to their crops. But what would happen if we treated climate change as a health problem rather than an environmental one?

The higher the level of particulates in the air, a new study shows, the greater the indications of psychological distress. Where a person lives can make a big difference to health and quality of life. Every increase in pollution of 5 micrograms per cubic meter had the same effect as a 1.5-year loss in education.

What substances in wildfire smoke are most dangerous to human health? What kinds of impacts can they have? Is a brief exposure, say for a few hours, dangerous, or is smoke mainly a concern if it lingers for days?

New sales of petrol and diesel cars will be banned by 2040 in the UK; France. Sweden and Scotland by 2032; Norway by 2025. Coupled with increasing concern over the carcinogenic effects of diesel emissions, the Volkswagen defeat device scandal, and the link between diesel particulates and Alzheimer’s, focus has turned again to electric cars. 

In the end, the military campaign was called Operation Ranch Hand, but it originally went by a more appropriately hellish appellation

The updated Toxic Substances Control Act brings new hope for protecting Americans’ health and environment. Here's what it does — and doesn’t — do.

The fracking industry has been an energy success story: Natural gas prices have decreased as fracking has skyrocketed, and natural gas now produces more electricity than coal does, which has resulted in improved air quality.

A good night’s sleep is a crucial aspect to overall health and well-being, yet so many Americans are lacking in that department. A 2013 Gallup poll found that 40% of American adults get less than the recommended amount of sleep.

"This is a global issue rather than one that's simply isolated in China; multidrug resistance is just a plane ride away," says James Tiedje.

The Dutch famine of 1944 was a terrible time for many in the Netherlands – with around 4.5m people affected and reliant on soup kitchens after food supplies were stopped from getting into the area by German blockades. As many as 22,000 people were thought to have died, and those who survived would find...

A new water filter can remove toxic heavy metal ions and radioactive substances in just one pass.

The ongoing water crisis in Flint, Michigan has highlighted just how harmful lead contamination is. What you may not realize, however, is that lead exposure is a problem throughout the U.S.

What do you know about your endocrine system? Possibly not as much as you should, seeing as how almost every organ and cell in the body is affected by it. This under-appreciated collection of glands selects and removes materials from the blood, processes them and secretes the finished chemical products, or hormones, back into the bloodstream.

Alongside the day’s high and low temperatures, weather reports generally contain a UV alert for a particular time. But what does it actually mean – and what should you do about it?

Researchers report that the children of mothers who experienced higher levels of exposure to perfluorooctanoic acid while pregnant had higher body fat and faster weight gain through age 8. The participants live downstream from a chemical plant that used PFOA.

Mercury pollution is one of the most insidious problems in our environment. Today my colleagues and I at Flinders University have unveiled a new material than can scrub mercury from the environment, as a result of research to be published this week.

We all know about the obvious dangers of DIY and construction work – smashed thumbs, stubbed toes and so on. Even hanging wallpaper results in 1,500 British people going to hospital every year.

Over the past ten years in the United States, unconventional gas and oil drilling using hydraulic fracturing, or fracking, has experienced a meteoric increase. Since well drilling requires an influx of water, materials and workers into yotherwise rural and remote areas, the question has been: could air, water and noise pollution negatively impact on the health of nearby residents?

Recent research has reignited concerns that exposure to chemicals from plastics might be to blame for low sperm counts in young men. I share the concerns about the high prevalence of low sperm counts (one in six young men), and my research is directed at trying to identify what causes it. But whether plastics are to blame isn’t a simple matter.

The research, from the Children’s Hospital of Los Angeles, measured the exposure of the mothers to PAH air pollution and used brain imaging to look at the effects on their children’s brains.

We all suffer from too little sleep from time to time, some more than others. There are many possible reasons, depending on our age, genes and sleep habits; but another possible culprit is using technology before going to sleep.
