The EPA’s free AIRNow app for Apple or Android phones allows users to enter a Zip Code and receive the pollutant and ozone levels for more than 400 cities across the country. You can also choose to check your current location.

The app gives levels for ozone and particle pollution such as automotive exhaust and an overall assessment of “good,” “moderate,” “unhealthy for sensitive groups,” “unhealthy,” “very unhealthy” and “hazardous.”

People with heart or lung conditions, children and older adults are most at risk when particle pollution, called PM 2.5, is elevated, according to the EPA. PM 2.5 measures the number of particles 2.5 micrometers in diameter or smaller, about 30 times smaller in diameter than the human hair. These particles come from a wide variety of sources, including motor vehicles, wood stoves and industry.

Giant piles of debris from Japan’s earthquake and tsunami scar the country’s once picturesque northeast coast — and the clear-up is hamstrung by fears the rubbish may be contaminated by radiation.

Decades-worth of waste was left behind when the waters receded in March last year after claiming more than 19,000 lives.

The survivors are desperate to rebuild, but must first get rid of more than 22 million tons of rubbish — far too much for the disaster-struck region to deal with alone.

But despite appeals to national solidarity, worries over nuclear contamination from the crippled Fukushima power plant mean virtually no one elsewhere in Japan wants the debris processed near them.

The American Chemistry Council has defended the wide use of BPA and said that low doses of the chemical pose no human health risks. Still, the National Institutes of Health noted in a September 2011 paper that research with laboratory animals has shown low doses of BPA produces a wide spectrum of developmental and reproductive side effects, including an increase in aggressive behavior and early onset of sexual maturation.

Recent studies also have raised concern that exposure to the chemical is as frequent as checking out at the grocery store. Receipts and canned food top the list of BPA sources for the average consumer. Here’s the evidence:…read more: Top BPA sources | cleveland.com.

When I wrote recently about the next generation of genetically engineered seeds, I was in truth referring to the next next generation. The fact is that the next actual generation of seeds is already out of the lab and poised for approval by the USDA.

And I’m not talking about Monsanto’s recently approved “drought-tolerant” seeds, which the USDA itself has observed are no more drought-tolerant than existing conventional hybrids.

No, the “exciting” new seeds are simply resistant to more than one kind of pesticide. Rather than resisting Monsanto’s glyphosate-based Roundup alone, they will now also be resistant to Dow AgroScience’s pesticide 2,4-D .

“A new pesticide,“ you say. “How exciting!” Except 2,4-D, despite its catchy name, has been around since World War II. Not only is it one of the most commonly used pesticides in the world, but it came to further prominence in certain circles when it was incorporated as a main ingredient in Agent Orange.

Indeed, as with research into new antibiotics, research into new — potentially safer — pesticides has come to a virtual standstill. Like the drug pipeline, the pesticide pipeline has run dry. Instead, biotech companies are going back to the older, more toxic chemicals, like 2,4-D, for inspiration.

And while you’d expect opposition to these new products from the likes of Tom Philpott of Mother Jones or Doug Gurian-Sherman of the Union of Concerned Scientists, one place you might not expect to see it is the pages of the influential, peer-reviewed journal BioScience.

And yet there it is! Led by David Mortensen, a team of scientists from Penn State, Montana State, and the University of New Hampshire published a paper that describes the effects on agriculture from an over-reliance on glyphosate and an overuse of Monsanto’s genetically modified seeds. It also discusses at length the risks of using new seeds that “stack” resistance to various pesticides into one genetically engineered package.

In short, they say that you can’t believe Monsanto and Dow when they hype gyphosate resistance plus 2,4-D resistance as two great tastes that taste great together. The two companies are promising to eliminate the growing superweed menace — the one that has caused farmers to abandon thousands of acres of prime farmland and to return to older, more toxic pesticides to protect their crops.

What these scientists conclude is that with so many weeds resistant to glyphosate already, it won’t take long for them to develop resistance to 2,4-D as well.  According to the study’s authors, almost half of the nearly 40 species of weeds that are already resistant to two pesticides have arisen since 2005 (i.e. since the Roundup Ready era began). In short, the crisis Monsanto and Dow are promising to head off is already here.

There are other problems with 2,4-D, such as a strong link to cancer and a much greater tendency to drift on the wind (and thus contaminate nearby fields and waterways) — problems that the development of the less toxic, less volatile glyphosate was supposed to have “solved.” Yet now, thanks to Big Ag’s over-reliance on these genetically engineered one-hit wonders, which encouraged farmers to use too much glyphosate too often, we’re back to square one — or rather to square toxic.

There is, however, an alternative — and one that doesn’t require a total transition to organic agriculture (not that there’s anything wrong with that!). Mortensen and his team describe in detail a practice called Integrated Weed Management (IWM). Like its sibling, Integrated Pest Management (IPM), IWM does involve the use of chemical pesticides. But it’s a judicious use that can act as a last resort rather than a first line of defense. As the paper states:

IWM integrates tactics, such as crop rotation, cover crops, competitive crop cultivars, the judicious use of tillage, and targeted herbicide application, to reduce weed populations and selection pressures that drive the evolution of resistant weeds.

It’s designed for production agriculture and would most likely increase farmer profits, since farmers would get the benefit of reduced seed and pesticide costs and no real loss of productivity. But, as with the climate-friendly agriculture I discussed the other day, you’re unlikely to see IWM embraced by Big Ag any time soon.

The USDA, along with the entire large-scale agriculture economy, is built around the profits of pesticide and biotech companies. You need only watch the USDA approve new genetically engineered products — which the agency admits represents a threat to other forms of agriculture — to see how deep in the tank to these companies our government is.

Tom Philpott observed that with this latest development, agriculture is at “a crossroads.” I disagree. I would say that if the USDA approves this new multiple pesticide-resistant GMO seed as it’s expected to, large-scale agriculture in the country will have reached a true dead end.

On November 6, 2011, Bill McKibben arrived at Washington, D.C.’s, Lafayette Park to protest the proposed Keystone XL pipeline, designed to carry oil 1,700 miles from Alberta, Canada, to refineries on the Gulf of Mexico. McKibben, a Vermont writer and environmentalist, had been one of 1,252 people arrested in front of the White House in August and September, protesting the same pipeline. He’d spent two nights in the district’s Central Cell Block, and now was back with thousands more people and a bold new plan.

“We can’t literally occupy the White House,” McKibben had told his fellow protesters, “so the next best thing is to surround it.” And that’s what they would do, encircle the White House in a “giant hug” to remind President Obama of his campaign promise to “end the tyranny of oil.” McKibben wasn’t sure how many people he would need to “hug” the White House, though, and was worried that he wouldn’t have enough.

There has been a lot of talk about the safety of the proposed Keystone XL pipeline.

I am not an environmentalist, but as a civil engineer and an inspector for TransCanada during the construction of the first Keystone pipeline, I’ve had an uncomfortable front-row seat to the disaster that Keystone XL could bring about all along its pathway.

Despite its boosters’ advertising, this project is not about jobs or energy security. It is about money. And whenever my former employer Bechtel, working on behalf of TransCanada, had to choose between safety and saving money, they chose to save money.

As an inspector, my job was to monitor the construction of the first Keystone pipeline. I oversaw construction at the pump stations that have been such a problem on that line, which has already spilled more than a dozen times. I am coming forward because my kids encouraged me to tell the truth about what was done and covered up.

When I last raised concerns about corners being cut, I lost my job — but people along the Keystone XL pathway have a lot more to lose if this project moves forward with the same shoddy work.

What did I see? Cheap foreign steel that cracked when workers tried to weld it, foundations for pump stations that you would never consider using in your own home, fudged safety tests, Bechtel staffers explaining away leaks during pressure tests as “not too bad,” shortcuts on the steel and rebar that are essential for safe pipeline operation and siting of facilities on completely inappropriate spots like wetlands.

I shared these concerns with my bosses, who communicated them to the bigwigs at TransCanada, but nothing changed. TransCanada didn’t appear to care. That is why I was not surprised to hear about the big spill in Ludden, N.D., where a 60-foot plume of crude spewed tens of thousands of gallons of toxic tar sands oil and fouled neighboring fields.

TransCanada says that the performance has been OK. Fourteen spills is not so bad. And that the pump stations don’t really count. That is all bunk. This thing shouldn’t be leaking like a sieve in its first year — what do you think happens decades from now after moving billions of barrels of the most corrosive oil on the planet?

Let’s be clear — I am an engineer; I am not telling you we shouldn’t build pipelines. We just should not build this one.

Pipelines can and do stand the test of time, but TransCanada already has shown that they cannot. After working on engineering projects all over the world, I can tell you that a company that cared about safety would not follow these types of practices.

If it were a car, the first Keystone would be a lemon. And it would be far worse to double down on a proven loser with Keystone XL.

The stories of how TransCanada has bullied landowners in Nebraska rings true to me. I am living it, as well. After repeatedly telling the contractor and TransCanada about my concerns, I lost my job.

But I couldn’t watch silently as a company put innocent people at risk with a haphazardly built pipeline. I am speaking out on behalf of my children and your children.

Oil spills are no joke. We need to do all we can to protect our water and our food. I am glad the Nebraska Legislature stepped up to protect Nebraskans. I can only hope that they stand up to TransCanada. We should all take a hard look at the damage that this pipeline will do. I should know; I’ve seen it in person.

Please do not sell out to foreign oil and foreign suppliers. There is no guarantee the product will stay in the United States, only the toxic waste. God bless the United States and those of us who still believe in the fact that her people matter.

Let’s get the New Year off to a fresh start by tackling this sickening situation. In public spaces across the country, including offices, stores, restaurants, airports, and schools, air "freshener" is being forced upon us. Daily we are subjected to known carcinogens, endocrine disruptors, and other toxic substances. Sounds like a horror film, but it is our scentsational reality.We’ve talked before about the hazards inherent in air fresheners. The EPA puts it quite poetically: "Air fresheners are usually highly flammable and also strong irritants to eyes, skin, and throat. Additionally, the solid fresheners usually cause death if eaten by people or pets."Yes, these household helpers — which became popular in the 1950s, along with perky smiles and perfect apple pies — contain all manner of harmful ingredients, including formaldehyde, a powerful pesticide called paradichlorobenzene, and phthalates. In short, air "fresheners" actually make our air quality much worse, polluting our space and our bodies. To quote the EPA again, "air fresheners … release pollutants more or less continuously."

Here’s another interesting story I wrote this year..what a cool biz: Recycling humans and animals!-tr

RTI Biologics employs 700 people worldwide, 500 of these at the Alachua headquarters. The spotlessly clean facility operates 24/7, with receiving facilities always ready for gifts of human donated tissue, which are quarantined in freezers on first arrival, while testing and screening is conducted to determine if the tissue is safe for transplantation. The tissue is shaped into its final form, then sterilized through one of RTI’s proprietary tissue sterilization processes before being distributed to surgeons worldwide.
