A study links soil metals with cancer mortality

Fri, 20 Apr 18 00:07:10 -0700

Spanish epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth's surface on the geographical distribution of tumors should be analyzed.

The changing chemistry of the Amazonian atmosphere

Wed, 11 Apr 18 00:15:40 -0700

Researchers have been debating whether nitrogen oxides (NOx) can affect levels of OH radicals in a pristine atmosphere but quantifying that relationship has been difficult. Now, Harvard researchers have found that accompanying the increase of NOx concentration from urban pollution, daytime peak OH concentrations in the rainforest skyrocketed, increasing by at least 250 percent. These increased levels of OH concentrations in the Amazon atmosphere could lead to changes in atmospheric chemistry, cloud formation, and rainfall

The great acceleration reaches new heights

Wed, 04 Apr 18 00:07:30 -0700

An international team of researchers, including researchers at Edysan laboratorie (CNRS / Université de Picardie Jules Verne) has observed an acceleration in the increase of biodiversity on mountain peaks in Europe. This is a new indicator of the 'great acceleration': an increasingly rapid inflation of different parameters around the world (glacier retreat, coral bleaching, etc.) seen in recent years as a result of climate change. Mountain ecosystems could be seriously disturbed as a result.

Land use change has warmed the Earth's surface

Tue, 20 Feb 18 00:03:30 -0800

High levels of microplastics found in Northwest Atlantic fish

Fri, 16 Feb 18 00:15:00 -0800

A new study finds 73 percent of mesopelagic fish caught in the Northwest Atlantic had microplastics in their stomachs -- one of the highest levels globally. Typically living at depths of 200-1,000 meters, these fish could spread microplastic pollution throughout the marine ecosystem, by carrying microplastics from the surface down to deeper waters. They are also prey for fish eaten by humans, meaning that microplastics could indirectly contaminate our food supply.

Polluted air may pollute our morality

Wed, 07 Feb 18 00:06:20 -0800

Exposure to air pollution, even imagining exposure to air pollution, may lead to unethical behavior, according to findings published in Psychological Science, a journal of the Association for Psychological Science. A combination of archival and experimental studies indicates that exposure to air pollution, either physically or mentally, is linked with unethical behavior such as crime and cheating. The experimental findings suggest that this association may be due, at least in part, to increased anxiety.

Scientists explain the impacts of aerosol radiative forcing

Mon, 05 Feb 18 00:07:40 -0800

Aerosol optical properties and direct radiative effects on surface irradiance were examined using seven years (2006-2012) of Cimel sunphotometer data collected at Panyu--the main atmospheric composition monitoring station in the Pearl River Delta (PRD) region of China. Optical properties and radiative impacts of the absorbing particles can be used to improve the accuracy of inversion algorithms for satellite-based aerosol retrievals in the PRD region and to better constrain the climate effect of aerosols in climate models.

An underestimated threat: Land-based pollution with microplastics

Mon, 05 Feb 18 00:09:10 -0800

Tiny plastic particles also present a threat to creatures on land and may have damaging effects similar or even more problematic than in our oceans. Researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and their Berlin colleagues warn: the impact of microplastics in soils, sediments and the freshwaters could have a long-term negative effect on terrestrial ecosystems throughout the world.
