Nanoparticles can travel from lungs to blood, possibly explaining risks to heart
Wed, 26 Apr 2017 09:23:54 EDT
Tiny particles in air pollution have been associated with cardiovascular disease, which can lead to premature death. But how particles inhaled into the lungs can affect blood vessels and the heart has remained a mystery. Now, scientists have found evidence in human and animal studies that inhaled nanoparticles can travel from the lungs into the bloodstream, potentially explaining the link between air pollution and cardiovascular disease.

Antarctica and the Southern Ocean are not in better environmental shape than the rest of the world.
Toronto's subways expose passengers to more air pollution than Montreal, Vancouver systems
Tue, 25 Apr 2017 09:22:58 EDT
Subways increase our personal exposure to certain pollutants, even as they decrease overall emissions, research finds. Another finding from this study is that Toronto has the highest levels in Canada.
New approach to improve detection of landfill-related pollution
Mon, 24 Apr 2017 11:07:17 EDT
A method known as laser induced breakdown spectroscopy (LIBS) offers a cleaner, faster and simpler approach than existing technologies for detecting contaminants in the fluids coming from landfills, known as leachates.
Ambulances respond more slowly in summer and winter
Mon, 24 Apr 2017 09:39:40 EDT
Ambulance response times in London worsen when air temperatures rise or fall beyond certain limits in summer and winter, according to a new study.
Making bins more convenient boosts recycling and composting rates
Fri, 21 Apr 2017 12:32:55 EDT
Want to recycle or compost more? Try moving the bins closer, new research suggests. The study shows that placing bins 1.5 meters away from suite doors drastically boosts recycling and composting rates by 141 per cent. The findings highlight how small changes in convenience can have a big impact on performance.
BP oil spill did $17.2 billion in damage to natural resources, scientists find
Thu, 20 Apr 2017 14:18:25 EDT
The 2010 BP Deepwater Horizon oil spill did $17.2 billion in damage to the natural resources in the Gulf of Mexico, a team of scientists recently found after a six-year study of the impact of the largest oil spill in US history.
Rising water temperatures endanger health of coastal ecosystems, study finds
Thu, 20 Apr 2017 13:46:29 EDT
Increasing water temperatures are responsible for the accumulation of a chemical called nitrite in marine environments throughout the world, a symptom of broader changes in normal ocean biochemical pathways that could ultimately disrupt ocean food webs.
EPA methane emission policy likely to cost less, miss 2025 targets
Thu, 20 Apr 2017 09:02:25 EDT
Research shows plugging methane leaks will cost about a third less than the EPA estimates, further underscoring the cost-effectiveness of emissions mitigation -- but the agency will also likely fall short of its 2025 reduction targets.
Chesapeake Bay pollution extends to early 19th century
Wed, 19 Apr 2017 17:04:02 EDT
Humans began measurably and negatively impacting water quality in the Chesapeake Bay in the first half of the 19th century, according to a study of eastern oysters.
Canary in the kelp forest: Sea creature dissolves in today's warming, acidic waters
Wed, 19 Apr 2017 13:19:35 EDT
The one-two punch of warming waters and ocean acidification is predisposing some marine animals to dissolving quickly under conditions already occurring off the Northern California coast, according to a new study.
New method to create the next fuel-efficient renewable energy developed
Wed, 19 Apr 2017 12:20:12 EDT
The fossil fuel fight goes on for scientists as they develop a new method for creating reversible hydrogen storage based on methanol, with no carbon emissions, in the last major paper co-authored by USC's first Nobel laureate, the late George Olah.

Women of childbearing age living in four Pacific Island countries have elevated levels of mercury in their bodies, a new study reveals.
Making oil from algae: Towards more efficient biofuels
Wed, 19 Apr 2017 09:31:46 EDT
The mechanism behind oil synthesis within microalgae cells has now been revealed by a research team. This discovery could contribute to the development of biofuels, they say.
Tracking down water pollution through DNA of algae
Tue, 18 Apr 2017 11:43:44 EDT
The degree of pollution of rivers resulting from human activities is assessed using different biotic indices. The latter reflect the ecological status of a river based on the quantity and diversity of organisms selected as bioindicators, due to their ecological preferences and tolerance to pollution. This is the case of diatoms, algae consisting of a single cell surrounded by a silica skeleton, recommended by researchers as one of the ideal bioindicators for rivers and lakes.
