Eliminating indoor air pollution can be as simple as dotting your house or office with potted plants, according to research stretching back as far as the space program of the 1980s.

It’s a widely held misconception that staying indoors avoids exposure to air pollutants. Indoor air quality, in fact, is usually worse because contaminants that emanate from a vast assortment of consumer products add to the pollution that drifts in from the outside.

Given that urban dwellers pass 90% of their time inside, any strategy to improve indoor air quality is of widespread interest, especially one as appealing and environmentally sustainable as adding potted plants to the décor.

Suburban Habitat Renewal

Suburban Habitat Restoration: One Backyard at a Time

Yards certified through the National Wildlife Federation can post this sign.

Yards certified through the National Wildlife Federation can post this sign.

Whether you fret over dwindling rainforests or attribute disappearance of neighborhood cats to displaced coyotes, most of us recognize loss of wildlife habitats as a growing environmental concern.

As an alternative to hand-wringing, the National Wildlife Federation offers ordinary citizens the means to take action by establishing a Certified Wildlife Habitat in their own backyard. It’s not only enjoyable but very easy. I know because I did it in a matter of weeks despite starting out a gardening illiterate unable to name one in ten plants in my own yard.

Here’s how the program works. A yard has to qualify in all five areas outlined below, but each offers a wide range of options and only one to three is required per category. Then there’s a two-page checklist to fill out – works on the honor system – and a $15 processing fee. That’s it.

So You Like that “New Car Smell?” Think again.
(#10 of the Plastic Plague Series)

toxicatanyspeedYour car’s interior is a major source of exposure to two classes of toxic chemicals, according to a first-of-its-kind report from the Ecology Center in Ann Arbor, Michigan.

Titled Toxic At Any Speed, the study measured levels of PBDEs (flame retardants) and phthalates (used to soften plastics) in both interior car dust and windshield film samples from cars made by 11 leading auto manufacturers.

These chemicals exude from seat covers, instrument panels, floor coverings and other plastic parts. Studies in lab animals have linked exposure to a variety of health effects, Read the rest of this entry »

A Wave of Green Hits Surfing Industry
by Sarah S. Mosko, Ph.D.

At first glance, surfing might seem like an inherently earth-friendly sport. Surfers paddle out and catch waves by sheer force of will and muscle. No need for fossil fuel-burning speed boats to get around. And, surfers have a reputation for caring about ocean pollution.

But a closer look reveals that, like most human activities, the environmental impact is far from nil and, consequently, there’s a nascent movement within the surfing industry to clean up it its act.

The Essentials
The bare necessities of surfing are surfboard, wetsuit, good waves and wheels to and fro. The waves are courtesy of Mother Nature, but the choices surfers make to otherwise outfit themselves determine the toll on the environment.

Better Food Choices Get Better Results in Global Warming Battle than Food Miles Reduction
By Sarah S. Mosko, Ph.D.

California Certified Farmers' Markets are "the real thing," places where genuine California farmers sell their fresh-picked crops directly to the public in over 500 communities throughout the state.

California Certified Farmers' Markets let genuine California farmers sell their fresh-picked crops directly to the public in over 500 communities throughout the state.

“Buying local” has become a mantra of many committed to shrinking their personal climate footprint by limiting the miles their food travels from producer to plate. The increasing globalization of food supplies has served to fan this trend.

However, a new study finds that what you eat has a far greater impact on greenhouse gas (GHG) emissions than where that food was produced. What’s more, saying no to red meat and dairy products even one day a week matters more than buying local all week long.

Number crunchers Christopher Weber and Scott Matthews at Carnegie Mellon University drew on U.S. government statistics from 1997 to expose the entire life-cycle GHG emissions associated with the diet of the average American household.

Emissions fell into one of four categories, starting with upstream supply chain transportation wherein equipment and supplies are supplied to food producers. Then comes the food production phase, followed by final delivery transportation from point of production to retailer. The latter is synonymous with so-called food-miles that are the focus of advocates of buying local. The fourth source of emissions occurs during wholesaling and retailing and includes store heating and air-conditioning and food refrigeration.

Zero Waste!
Let’s Get Out of This Dump

by Sarah S. Mosko, Ph.D .

We are a throw-away society

Our throw-away habits are making a dump out of our world.

A fond memory from my childhood is of visiting the neighborhood “dump” with my dad to drop off whatever refuse, like old tires, we could not burn in our backyard incinerator.

Nowadays, the local dump has been supplanted by centralized landfills, and major restrictions have been placed on backyard incineration. Our waste stream has been transformed also since the introduction of petroleum-based plastics, single-use disposables, and packaging excess. Too, products once designed for durability and repair have been replaced with flimsier versions intended to be tossed and replaced.

In short, we have become a throw away society. Read the rest of this entry »

It is a widespread misconception that staying indoors avoids exposure to air pollutants.

Indoor air quality, in fact, is generally worse because contaminants that arise from a vast assortment of consumer products add to the pollution that drifts in from the outside. Given that urban dwellers pass 90% of their time inside, strategies to improve indoor air quality are of interest to nearly everyone.

Indoor Air Chemistry
The chief forms of pollutants generated indoors are known as volatile organic compounds (VOCs) that off-gas primarily from common petroleum-based products. They are impossible to avoid since the sources are nearly endless: furniture, carpeting, paints, varnishes, paint strippers, synthetic building materials, air fresheners, cleaning solutions, toilet bowl deodorizers, personal care products, tobacco smoke, pesticides, and solvents in inks and adhesives.

The number of VOCs is also long – the U.S. EPA indicated that more than 900 had been identified in indoor air in a 1989 Report of Congress. While some pose no known danger to health, others are Read the rest of this entry »
