Pesticides persist in bee pollen, study says

,
An Irish study shows that pollen from several bee species retains traces of toxic substances from neonicotinoids. And researchers are concerned
The term "permafrost" refers to the type of perennially frozen (but not necessarily ice-covered) soil found in some cold regions. Photo: NPS Climate Change Response CC BY 2.0 DEED https://www.flickr.com/photos/npsclimatechange/27759123542Photo: NPS Climate Change Response CC BY 2.0 DEED

Superficial permafrost could (almost) disappear by 2100

,
By the end of the century, near-surface permafrost may exist only in the highlands of eastern Siberia, the High Arctic and northern Greenland. As was the case 3 million years ago

Climate change puts 40 percent of biodiversity in eastern Brazil at risk

,
In the Catinga forest rising temperatures threaten to destroy nearly half the biodiversity by 2060, a Brazilian study says. Ecosystem services are under threat
The influence exerted on the population composition of microorganisms comes from the ability of earthworms to influence soil structure, pH, nutrient availability and organic matter. Photo: benketaro Attribution 2.0 Generic (CC BY 2.0)benketaro Attribution 2.0 Generic (CC BY 2.0)

Earthworms are changing Canadian forests

Invasive species of earthworm affect microbial composition by altering overall soil conditions, Canadian research explains. Influencing nutrient and carbon cycling
In many cities in the United States and Canada, municipal waste incinerators were largely shut down in the 1970s in the face of growing concerns about air pollution. Photo: Fraser, Clayton B.

Waste incineration leaves a heavy legacy in soils

,
Where waste was once burned, higher concentrations of lead are detected in the soil, says research from Duke University. With obvious health consequences
Increasing urbanization results in the conversion of natural ecosystems into residential areas that incorporate green areas such as parks or lawns. Photo: Md.

Urbanization promotes increasing emissions from the soil

,
As a result of urbanization, soil nitrous oxide emissions increase 153%, according to a new study. At the same time, the ability to absorb methane is reduced
Under drought conditions, microbes produce more atmospheric compounds than they consume. Photo: Flore de Preneuf / World Bank Attribution-NonCommercial-NoDerivs 2.0 Generic (CC BY-NC-ND 2.0)Flore de Preneuf / World Bank Attribution-NonCommercial-NoDerivs 2.0 Generic (CC BY-NC-ND 2.0)

Here’s how drought stress alters soil function in the rainforest

,
Drought progressively reduces the ability of soil to consume biogenic volatile organic compounds according to a German study. The emission intensifies after soil rewetting

Solar farms may encourage soil erosion in U.S.

,
Virginia Tech researchers will analyze erosion risk in the state's solar installations. In the U.S., the problem is real. But several solutions are available
Present in several products, including fire extinguisher foam, fluoride-based pollutants, so-called PFAS or per- and polyfluoroalkyl substances, are extremely difficult to dispose of. Photo: Brett Clashman, U.S. Air Force Public domainPhoto: Brett Clashman, U.S. Air Force Public domain

Ball milling cleans soil of persistent fluoride

,
Researchers in New Zealand are testing a solution against fluoride pollution. The technique has made it possible to degrade per- and polyfluoroalkyl substances (PFAS) at the molecular level with 99.9 percent efficacy
