In land of gas drilling, battle for water that doesn’t reek or fizz.

It has been more than four decades since the first well was drilled in the natural gas field beneath this stretch of slow rolling alfalfa and sugar beet farms near Pavilion, Wyoming. But for some who live in the shadows of the Wind River Mountains, the drilling rigs have brought more than industry.

Coping with two-headed fish and other effects of selenium.

Like many Western waterways, in southern Wyoming Muddy Creek carries selenium, a natural poison that accumulates in the food chain much as mercury does. Now, researchers are studying the Muddy Creek watershed, trying to determine how much of the element occurs naturally, and how much is being released by human activity.

Fracking operation in Erie begins near two elementary schools.

Encana is preparing to drill the Canyon Creek well site, where a prairie rife with birds and a wetland alive with waterfowl separate it from the Creekside neighborhood. Red Hawk Elementary, which is now on summer break, is only a few hundreds yards south of the drilling site.

Paper strikes back: Defending books, mail and dollar bills.

Crumple it, drench it, lock it in a hot attic or a damp cellar, but paper can come back to life. And it is doing so now, after taking a battering from environmentalists, the Internet and a glum economy.

France to ban a Syngenta pesticide to protect bees.

France said it plans to ban a pesticide made by Swiss agro-chemical group Syngenta that is widely used to treat rapeseed crops, after scientists suggested it could pose danger to bees.

When cleaning up power plants, time is money.

New rules on pollution from coal plants will cost the American economy $175 billion to $275 billion between now and 2035, according to a new analysis from the Electric Power Research Institute, a nonprofit utility consortium.

Holy river now a great drain of India.

The Yamuna River is one of the holiest waterways in India. Despite the Yamuna's significance as one of a trinity of holy rivers, it is also one of India's most polluted.

Good times reignite the water wars.

Whisky's for drinking, Mark Twain is said to have observed, but water is for fighting over. And a fight there is in eastern Australia's irrigated farmlands, with a seemingly irreconciliable stand-off – among states and between farmers and conservationists.

World-class landfill closing in 'Rio.'

One of the world's largest open-air landfills, a vast, seaside mountain of trash in Rio de Janeiro, Brazil, where thousands of people have made a living sorting through the debris by hand, will close this weekend after 34 years in malodorous service.

Chemicals that make you fat.

Some researchers, including Bruce Blumberg of the University of California, Irvine, believe chemicals we’re unwittingly exposed to could be making us fat. If the timing is right, chemicals may be instructing stem cells to become fat cells.

Low-dose effects of endocrine disruptors, with Laura Vandenberg.

The body of scientific evidence so far suggests that even at very low doses, exposures to endocrine disruptors may have very real effects, and that low-dose effects may disappear at higher doses, giving an illusion of safety if chemicals are not tested at low-enough doses.

Feds to rule on cancer aid for WTC dust exposure.

A federal health official is expected to decide within days whether to expand an aid program for anyone sickened by World Trade Center dust to cover cancer, a move that would be cheered by many former ground zero workers, but could also prove costly and come at the expense of people with ailments more conclusively linked to 9/11's toxic fallout.

In Louisiana, rising seas threaten Native Americans' land.

It used to be a long walk for Theresa Dardar to reach her ancestors' cemetery here in coastal Louisiana. Now, a boat ride is necessary to visit the burial site, which is surrounded by water as coastal Louisiana sinks and the sea level around it rises.

Climate change bringing more ticks, infections.

An apparent rise in ticks crossing Canada’s southern border has the local health unit urging residents to use caution in wooded areas. "We’re fairly confident the number of ticks is increasing because of climate change," said Dave Dodgson, of the Hastings and Prince Edward Counties Health Unit.

In a dead, toxic town, life goes on for one couple.

Turn off the main road into this town and your car will nose-dive into a ditch. You’re not supposed to be here. Treece, Kansas, is dead. Air, water and dirt, all poisoned by decades of lead and zinc mining. The stores and filling station are gone. People, too, their houses torn down.

Scientists decry Ottawa’s plan to close environmental research centre.

Supporters from Canada and across the world are signing an online petition and writing letters urging the government to reverse its decision to close the Experimental Lakes Area, arguing the centre is irreplaceable and critical to public and ecosystem health.

Michigan approves Dow dioxin cleanup plan for Midland.

The Michigan Department of Environmental Quality said Friday it had accepted Dow Chemical Co.'s plan for cleaning up properties contaminated with dioxin released from its chemical plant in Midland.

D.C. toughens lead-paint disclosure requirements for home sellers, landlords.

District residents who plan to sell or rent their homes will now have to comply with tougher lead paint requirements that must be satisfied before the deal can go through. If the home in which you live or rent was built before 1978, chances are there is — or at one time was — lead paint.

White House releases plan to reduce asthma rates among Latinos.

A blueprint for a plan to reduce the rates of asthma among low-income and minority children was released Thursday, an effort taken on by several federal agencies.

Pro-smoking activists threaten and harass health campaigners.

Academics and health campaigners are being subjected to threats of violence, harassment and personal abuse by pro-smoking activists as UK ministers consult over whether tobacco should be sold only in plain packets.

PUBH 6165/8165, Environmental Health Service-Based Learning

The public posting of service-based environmental health learning activities is intended to foster a greater understanding of issues in environmental health, while also providing helpful and informative information to the “stakeholders” that may be affected by the issue.

The commentaries and presentations seen here are authored by public health graduate students enrolled at Walden University.

Welcome to the PUBH 6165/8165, Environmental Health service-based learning activity public weblog. In your respective section of PUBH 6165/8165, you will be posting a commentary, slide (or possibly a video) presentation on an environmental health issue that has potential impacts on a community.

For those of you unfamiliar with posting to a public weblog site, you may need to take a little time in the WordPress site – most of the procedures are intuitive.

Drs. Shana Morrell and Raymond W. Thron can assist you if you encounter difficulties. Send either Dr. Morrell or Dr. Thron and email to seek assistance.

Dr. Thron,
Though initially challenged with the process, I am enjoying this weblog experience for PUBH 6165. The PPT presentations I am able to view are wonderful, but I am unable to open many Walden submissions. Could this be because I have an older version of PPT on my home computer? If these presentations were saved in a 2007 version, could this be the reason that I cannot view them?

Thank you

  Good day!
  
  I am presuming that you have registered with WordPress, according to your comment. Remember that you will only be entered as an “author” once your instructor approved your final draft of your service-based learning activity project. This should be deposited to the week 9 application dropbox. If you receive a score of 6 or better, you instructor will inform one of the administrators for this Environmental Public Health Today [ http://environmentalhealthtoday.wordpress.com/ ] site. At this time you will be enrolled as an “author.”
  
  Hope that this offers some help.

  Without a password, one cannot access the site for publishing purposes. When you attempted to log in, I presume that you knew your username, and that you forgot your password. At the log in site, there should be an option called “Lost your password?” If you click on this, WordPress.com will send you a new password (at least, that’s how it is suppose to work). In order for you to get your new password, you will need to enter your email address – be sure to use your Walden University email address as you did when originally establishing the account.
  
  Hope that this offers some help.

    Thank you Dr. Thron for your speedy response. I have tried to reset repeatedly but it does not send me a new password, it sends me a link and the link sends me back to “lost password”, and then it starts over. Should I try a new user name and my home email? or Can my password be reset for me? I’ll await your response. Thank you So Much. Shelia

  To upload media (whether a powerpoint presentation, commentary, audio, video, etc.) go to the “media” folder from your Dashboard; then click on the icon titled “add new”. This is immediately to the right of the page title of “Media Library”. After clicking on “add new” you will be brought to the page titled “Upload New Media.” The allowed file types are shown. Browse to your commentary/presentation on your local computer to select your file. Uploading may take several minutes, particularly if the file is large, and also depending on the speed of your connection.

Elevated mercury exposure a by-product of Peruvian gold mining.

Living in Peruvian towns with small-scale mining is associated with an unhealthy body burden of mercury, a link confirmed by a recently published study.

Moms' exposure to PAHs at work raises risk of rare birth defect.

Babies born to mothers exposed in early pregnancy to pollutants in the workplace may have a higher risk of an umbilical cord defect called gastroschisis, a condition where the baby's organs poke out of the gut.

Summer heat variations can be fatal for unhealthy seniors.

More elderly people with heart and respiratory problems die when there is a larger difference between summertime high and low temperatures, a new U.S. study found.

BPA diminishes in vitro success.

Exposure to bisphenol A at levels commonly found in the general population may cut a woman's chance of getting pregnant if she is undergoing fertility treatment, a study from Harvard University finds.

Low-level cadmium exposure can increase female cancer risk.

Women exposed to low levels of cadmium in their food have changes in DNA markers that alter gene regulation and increase their cancer risk.

Study first to link geothermal gas to asthma.

Adults exposed to low levels of a toxic gas released by natural and industrial sources may experience wheezing, coughing and asthma attacks that require medication, finds a three-year study in Iceland.

Leather trash turns to medical treasure.

A versatile and potentially valuable natural material could be easily collected from the abundant waste produced when leather is made from animal hides, according to researchers from Spain who explain their novel process in the journal Green Chemistry.

Womens' chemical exposure during pregnancy promotes obesity in daughters.

Pre-birth exposures to low doses of a compound-- PFOA -- that has been widely found in fast food packaging and household products, may increase body weight in women but not men, a new study finds.

Low level, long exposure to lead linked to depression, anxiety in women.

Life-long, low-level lead exposure is associated with increased reports of depression and anxiety that is related to phobias in older women, according to newly published research.

Urban heat amplifies death risk for elderly.

During heat waves, elderly people living in city areas where night temperatures remain higher are more likely to succumb to the heat than those in nearby suburban areas where temperatures dip when the sun goes down.

Secondary pesticide exposure evident in children living with flower workers.

Children in Ecuador who live with flower plantation workers have lower levels of an essential nervous system enzyme than children who live with adults who do not work on flower farms, report researchers for the first time.

Masks can cut air pollution risks.
