Even small amounts of air pollution appear to raise the risk of a condition in pregnant women linked to premature births and lifelong neurological and respiratory disorders in their children, new Johns Hopkins Bloomberg School of Public Health research suggests.

Fine particles from car exhaust, power plants and other industrial sources are breathed into the lungs, but the scientists have now found evidence of the effects of that pollution in the pregnant women's placentas, the organ that connects her to her fetus and provides blood, oxygen and nutrition. They found that the greater the maternal exposure to air pollution, the more likely the pregnant women suffered from a condition called intrauterine inflammation, which can increase the risk of a number of health problems for her child from the fetal stage well into childhood.

It was 30 years ago that a meltdown at the V. I. Lenin Nuclear Power Station in the former Soviet Union released radioactive contaminants into the surroundings in northern Ukraine. Airborne contamination from what is now generally termed the Chernobyl disaster spread well beyond the immediate environs of the power plant, and a roughly 1000-square-mile region in Ukraine, Belarus and Russia remains cordoned off, an exclusion zone where human habitation is forbidden.

The radiation spill was a disaster for the environment and its biological inhabitants, but it also created a unique radio-ecological laboratory.

The American Lung Association has released its annual “State of the Air” report and its findings are troubling. Most Americans live in counties with air pollution so bad that it is a severe risk to their health. According to the report, that means 166 million people are at risk of an early death and significant health problems including asthma, developmental damage and cancer.

Without a doubt the most concerning discovery made by the American Lung Association was that short-term particle pollution had increased sharply since last year’s report: “Short-term spikes” of particle pollution hit record levels in seven of the 25 most polluted U.S. cities in this period.

So much methane is bubbling into a river surrounded by hundreds of fracking wells that it's a fire hazard! Local campaigners blame the coal seam gas industry for the gas releases which are spreading along Queensland's river Condamine and gaining in intensity.

So much methane gas is now bubbling up through the Condamine River in Queensland, Australia that it exploded with fire and held a large flame.

Gas seeping into the river began shortly after coal seam gas operations started nearby and is growing in volume and the stretch of river affected is expanding in length.

With only days to go before the deadline, Volkswagen AG (VW) and the U.S. government reached a partial settlement over how to deal with the automaker’s “dieselgate” emissions scandal.

Volkswagen agreed to fix or buy back some 500,000 vehicles caught up in the crisis. What wasn’t agreed upon is how much the company should pay in fines and compensation to consumers affected by the crisis.

The billions of single-celled marine organisms known as phytoplankton can drift from one region of the world's oceans to almost any other place on the globe in less than a decade, Princeton University researchers have found.

Unfortunately, the same principle can apply to plastic debris, radioactive particles and virtually any other man-made flotsam and jetsam that litter our seas, the researchers found. Pollution can thus become a problem far from where it originated within just a few years.

What if we could not only clean up the heavy metals in our water systems, but also recycle those metals and reuse them?

A new study from the Institute for Intelligent Systems in Germany and the Institute for Bioengineering of Catalonia in Spain suggests that, soon, we might be doing just that.

The globally increasing light pollution has negative effects on organisms and entire ecosystems. The consequences are especially hard on nocturnal insects, since their attraction to artificial light sources generally ends fatal. A new study by Swiss zoologists from the Universities of Basel and Zurich now shows that urban moths have learned to avoid light. The journal Biology Letters has published their results.

Some insects are attracted by light while others shy away from it. Proverbial is the attraction light has on moths. Street lamps and other artificial light sources often become death traps for nocturnal insects such as moths. Either they die through direct burning or through increased exposure to predators. Mortality of urban insects can thus be 40- to 100- fold higher than in rural populations.

People who reported consuming more fast food in a national survey were exposed to higher levels of potentially harmful chemicals known as phthalates, according to a study published today by researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. The study, one of the first to look at fast-food consumption and exposure to these chemicals, appears in the journal Environmental Health Perspectives.

The climate talks that concluded last December were a great success, but it will be decades before we can judge whether the Paris Agreement itself is ultimately successful. What can be said is that the accord provides a good foundation for meaningful progress on climate change, and represents a dramatic departure from the past 20 years of climate negotiations.

I have long viewed the dichotomous distinction between Annex I and non–Annex I countries in the Kyoto Protocol as the major stumbling block to progress. The protocol included mandatory emissions-reduction obligations for developed countries, but none for developing countries. That made progress impossible, because significant growth in emissions since the protocol came into force in 2005 has been entirely in the large developing countries — China, India, Brazil, South Korea, South Africa, Mexico, and Indonesia.
