For the first time since 2011, peak contamination levels in Pacific Canadian waters from Japan’s Fukushima Daiichi nuclear disaster are known, says a University of Victoria scientist who has been monitoring levels since the meltdown of three reactors at the plant.

Olive oil has long been a popular kitchen staple. Yet producing the oil creates a vast stream of wastewater that can foul waterways, reduce soil fertility and trigger extensive damage to nearby ecosystems. Now in a study appearing in ACS Sustainable Chemistry & Engineering, scientists report on the development of an environmentally friendly process that could transform this pollutant into “green” biofuel, bio-fertilizer and safe water for use in agricultural irrigation.

Nitrogen can present a dilemma for farmers and land managers.

A new filter produced by Rice University scientists has proven able to remove more than 90 percent of hydrocarbons, bacteria and particulates from contaminated water produced by hydraulic fracturing (fracking) operations at shale oil and gas wells.

In the year after Flint, Michigan changed its water supply to the lead-tainted Flint River, there was decrease in fertility and an increase in fetal deaths among residents, according to an analysis of health statistics by a team of U.S. economists.

A new IUPUI study funded by the U.S. Department of Agriculture answers a long-debated agricultural question: whether no-tillage alone is sufficient to prevent water pollution from nitrate. The answer is no.

Fires that span across the Northern Territory and Western Australia appear to have broken out in areas that have already been burned in previous fires.  Areas that sport "burn scars", those areas that are a darker, almost red-brown color, are surrounded by fires that are anywhere from a few hours old to 7 days old.  The areas that are seven days old can be attributed to fires that spread but areas that are just a few hours old may be fires that have presumably been put out only to have them break out again.  The Northern Territory of Australia experienced a higher than normal amount of rain this past season allowing the plants and trees that fuel fires to become even more overgrown and subject to becoming fire fodder.

Outdoor air pollution has long been linked to major health conditions such as heart disease, stroke, cancer, asthma and chronic obstructive pulmonary disease. A new study now adds kidney disease to the list, according to researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs (VA) St. Louis Health Care System.

Forest fires in Southeast Asia during the El Niño droughts of 2015 caused considerable disruption to the biodiversity of the region due to the smoke-induced ‘haze’ they created, according to new research led by Benjamin Lee at the University of Kent and the National Parks Board in Singapore.

People who handle paper receipts regularly may be at increased risk for exposure to a chemical linked to breast and prostate cancers, according to new UAlberta research.

“We found that people who handled receipts printed on thermal paper containing the chemical had it lingering in their body for a week or more,” said Jiaying Liu, a PhD candidate in UAlberta’s Department of Laboratory Medicine and Pathology.
