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 the European Union and Switzerland as one of the ideal bioindicators for rivers and lakes.
When water comes in for a landing on the common catalyst titanium oxide, it splits into hydroxyls just under half the time. Water's oxygen and hydrogen atoms shift back and forth between existing as water or hydroxyls, and water has the slightest advantage, like the score in a highly competitive tennis game.

More than 2 million poisonings are reported each year to poison centers across the United States, and half those calls involve children under 6. As part of National Poison Prevention Week CHLA pediatric medical toxicologist Cyrus Rangan, M.D. shares tips for preventing poisoning in the home.
The study, led by doctoral student Rachel Rubin, determined bacteria could play a significant role in increasing crop yields in the future, even in times of drought
Researchers with expertise in a wide range of water-related issues will converge this month for the SEC Academic Conference to discuss the often complex issues related to the earth’s most life-giving resource.
The Science for Nature and People Partnership (SNAPP) has issued an open call for funding proposals to convene interdisciplinary teams tackling questions at the heart of sustainable economic development, human well-being, and natural resource conservation.
While lead pipes were banned decades ago, they still supply millions of American households with water each day. A team of engineers at Washington University in St. Louis has developed a new way to track where dangerous lead particles might be transported in the drinking-water supply during a common abatement procedure.
For decades, phosphorous has accumulated in Wisconsin soils. Though farmers have taken steps to reduce the quantity of the agricultural nutrient applied to and running off their fields, a new study from the University of Wisconsin-Madison reveals that a "legacy" of abundant soil phosphorus in the Yahara watershed of Southern Wisconsin has a large, direct and long-lasting impact on water quality.
Using solar energy, Technion researchers have developed a new method for safely and efficiently producing hydrogen in a centralized manner, miles away from the solar farm. It could greatly reduce the cost of producing hydrogen and shipping it to customers.
Writing in the Journal of Pediatrics, UB researcher says public health experts need to be more up front with parents in explaining that CDC dietary recommendations may not help children who have been exposed to lead.
Scientists at Berkeley Lab and Caltech have—in just two years—nearly doubled the number of materials known to have potential for use in solar fuels. They did so by developing a process that promises to speed the discovery of commercially viable generation of solar fuels that could replace coal, oil, and other fossil fuels.
Researchers at The Ohio State University have discovered that food waste can partially replace the petroleum-based filler that has been used in manufacturing tires for more than a century. In tests, rubber made with the new fillers exceeds industrial standards for performance, which may ultimately open up new applications for rubber.
Higher intake of foods containing isoflavones, estrogen-like compounds primarily found in soy, is associated with reduced all-cause mortality in women with hormone-receptor-negative breast cancer and women not treated with hormone therapy as part of cancer treatment.
Nearly 1 in 4 U.S. citizens gets food poisoning every year, but very few report it. Twitter communications between the public and the proper government authorities could improve foodborne illness reporting as well as the steps that follow, according to a new study from the Brown School at Washington University in St. Louis.
If you’re sick, stay home. Wash your hands before preparing food. When preparing food, always wear gloves or do not touch the ready-to-eat food with bare hands. For food service workers, following this simple advice, which is part of the FDA Food Code, could drastically reduce the spread of norovirus, the most common type of foodborne illness. These results come from a new U.S. Food and Drug Administration study published in the latest issue of Risk Analysis, the scholarly journal of the Society for Risk Analysis.
Wastewater from oil and gas operations – including fracking for shale gas – at a West Virginia site altered microbes downstream, according to a Rutgers-led study. The study, published recently in Science of the Total Environment, showed that wastewater releases, including briny water that contained petroleum and other pollutants, altered the diversity, numbers and functions of microbes. The shifts in the microbial community indicated changes in their respiration and nutrient cycling, along with signs of stress.
