Tetrachloroethylene Toxicity EPA Risk Assessment
February 13, 2012 11:04 AM - Editor, ENN
Tetrachloroethylene, also known under its systematic name tetrachloroethene and many other names, is a chlorocarbon. It is a colorless liquid widely used for dry cleaning of fabrics and is sometimes called "dry-cleaning fluid". It has a sweet odor detectable by most people at a concentration of 1 part per million (1 ppm). It is also used in the cleaning of metal machinery and to manufacture some consumer products and other chemicals. Confirming longstanding scientific understanding and research, the final EPA risk assessment characterizes this material as a likely human carcinogen. The assessment provides estimates for both cancer and non-cancer effects associated with exposure to it over a lifetime.
Innovative Wastewater Treatment Technology
February 13, 2012 07:01 AM - CleanTechies Guest Author, Clean Techies
Israel’s Aqwise is proving to be a success story of international proportions in the arena of biological wastewater treatment. The Company began as a small start-up offering innovative biological treatment of urban wastewater, and today offers a variety of solutions for municipal and industrial customers, due to intensive R&D and expansion into new arenas of activity. According to Israel NewTech, Aqwise is one of the first companies which singled out the potential of the cleantech market for Israeli hi-tech based entrepreneurs. The Company began as a small start-up, which developed innovative technology for the biological treatment of wastewater. Now, 12 years later, the Company is profitable, has 150 installations around the world, and representation and partnerships in over 20 countries.
Housecats Susceptible to Wild Feline Disease
February 8, 2012 10:13 AM - David A Gabel, ENN
There are really two types of cats out there: the cute and cuddly house cat and the vicious predator wildcats. However, for bacteria and viruses, there is no difference. The domestic cats are equally vulnerable to the same diseases that afflict wild bobcats, cougars, and others. A new study led by Colorado State University found that all cats living in the same area share the same diseases. In fact, domestic cats can act as a bridge to spread feline diseases to human households.
Once, men abused slaves. Now we abuse fossil fuels
February 6, 2012 04:51 PM - Andy Gryce, Population Matters
Pointing out the similarities (and differences) between slavery and the use of fossil fuels can help us engage with climate change in a new way, says Jean-François Mouhot, visiting researcher at Georgetown University, USA. In 2005, while teaching history at a French university, I was struck by the general disbelief among students that rational and sensitive human beings could ever hold others in bondage. Slavery was so obviously evil that slave-holders could only have been barbarians. My students could not entertain the idea that some slave-owners could have been genuinely blind to the harm they were doing. At the same time, I was reading a book on climate change which noted how today's machinery — almost exclusively powered by fossil fuels like coal and oil — does the same work that used to be done by slaves and servants. "Energy slaves" now do our laundry, cook our food, transport us, entertain us, and do most of the hard work needed for our survival.
Deadly Malaria on the Decline
February 6, 2012 10:15 AM - David A Gabel, ENN
A new research study has found that malaria is killing twice as many people that previously believed. However, as efforts to combat the deadly steam have picked up, the total number of deaths is declining. In 2010, 1.2 million people died of malaria, twice as much as the last survey suggested. Researchers from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington believe that the discrepancy is due to the previous studies assuming that malaria only kills children under age five. In actuality, 42 percent of malaria deaths are people aged five and older.
Arrested for Excessive Sweetness
February 3, 2012 04:07 PM - David A Gabel, ENN
Put your hands up and step away from the sugar! No, not really. But one day, sugar may be a regulated substance, on par with alcohol and tobacco. The notion seems draconian at first, but once you look at the reasoning behind it, it begins to make a lot of sense. Researchers from the University of California (UC) San Francisco stipulate that excessive consumption of sugar is behind the global obesity pandemic. Sugar contributes to over 35 million deaths per year from diabetes, heart disease, cancer, and other diseases. Their desire is to see a healthier world with fewer health-related costs through the restriction and regulation of sugar.
UPS Foundation Donates $6M To Champion Diversity
February 2, 2012 06:04 AM - Editor, ENN, Justmeans
It's good news for the human environment. The UPS Foundation today announced almost 120 grants totaling more than $6 million to non-profit organizations around the world that champion diversity and support diverse communities. For more than 60 years, UPS's philanthropic arm has funded organizations that support under-served and under-represented members of society. This year’s grants will support a wide range of programs, including those for wounded veterans, the hearing and visually-impaired, women and girls and culturally distinct populations.
Do Pollutants Cause Breast Cancer?
January 30, 2012 02:52 PM - Paloma D’Silva, Sierra Club Green Home
Breast cancer is partly caused by toxic chemicals in the environment, according to a recent study by the Institute of Medicine (IOM). These pollutants are surprisingly common, and most women are exposed to them from a variety of sources. Carcinogenic pollutants come from radiation and from consumer products. They are in household cleaning products, microwaves, cosmetics, hairsprays, and refrigerators. These chemicals seep into water as runoff from landfills, affect people as well as animals, and have been shown to cause breast cancer in women. The Breast Cancer Action Foundation believes that the environmental factor has been overlooked in research, and that its influence has been grossly underestimated.
Strong Work Ethics Stem from Early Childhood Development
January 30, 2012 09:46 AM - David A Gabel, ENN
A new study recently published suggests that attentiveness in kindergarten can accurately predict the child's work-oriented behavior throughout the rest of their school years and throughout their entire lives. This conclusion came after years of analysis and observation from elementary school homeroom teachers. For a young child, the classroom is the work place, so skills obtained there are translated directly to their adult workplaces. This study places even more focus on the importance of early education in shaping a more productive, work-oriented society.
Why Biodiversity Loss Deserves as Much Attention as Climate Change
January 27, 2012 01:58 PM - Akhila Vijayaraghavan, Triple Pundit
Biodiversity loss is probably a challenge that is often ignored as climate change looms. Currently the world is losing species at a rate that is 100 to 1000 times faster than the natural extinction rate, further, it is currently seeing the sixth mass extinction. The previous mass extinction occured 65 million years ago, and was caused by ecosystem changes, changes in atmospheric chemistry, impacts of asteroids and volcanoes. For the first time in history, the current extinction is caused by the competition for resources between a single species Homo sapiens and all others. A recent conference arranged by the Danish Ministry of Environment in the University of Copenhagen, provided an opportunity to influence the process of organizing a UN Biodiversity Panel. More than 100 scientists and decision makers from the EU countries gathered and came to the conclusion that drastic measures should be taken to decelerate current loss of biodiversity.
