Perhaps you already bring your own reusable grocery bags, have kicked the bottled water habit and know better than to microwave in plastics, but still find daily life swimming in plastics and want to use less of it. After recycling, the average American still generates a half pound of plastic refuse daily, a concrete indicator of how deeply entrenched are plastic materials in our 21st century lifestyle (USEPA, 2010).
Rational reasons to cut back on plastics fall into one of two spheres: limiting exposure to hazardous chemicals associated with plastics – like bisphenol-A, phthalates and flame retardants – or reducing the harm to the environment incurred at all stages in plastics’ lifecycle, from extraction of the petroleum needed for manufacturing to disposal of the non-biodegradable finished products.
Short of adopting a Tarzan-like jungle existence, it’s probably impossible to completely eliminate plastics from modern day life, but with a little digging and shopping savvy, you can enlarge that dent in your plastics consumption. Some ideas follow.

Common objects contain endocrine disruptors
In pregnant women, exposure today to endocrine-disrupting substances common in everyday plastics might not only be adversely affecting the health of their fetuses, but the health and fertility of their future great grandchildren might also be at risk, according to a laboratory study just published in January. The health risks are not handed down via changes to the genetic DNA code (i.e. gene mutations), but rather through a parallel biological scheme of coding known as “epigenetics.”
Background
Traits are passed from one generation to the next through two distinct but interacting vehicles of inheritance. The genes that make up our DNA were once thought to contain the entire blueprint for all inherited traits. For some time, however, scientists have understood the critical role of another coding system that literally sits atop the DNA and instructs genes to turn on or off. Because all cells in a given animal or human have the same DNA sequence as the original fertilized egg and sperm, another mechanism is needed to explain how cell differentiation occurs during development so that a heart cell, for example, ends up so different from, say, a brain or skin cell.

The simple fact that Americans consume 1500 single-serve water bottles per second made of PET plastic has sufficed to make these disposable bottles a target of environmentalists concerned about the impact of so much trash. Until very recently, however, it has been assumed that the PET bottles pose no direct health risk to humans who drink from them.
New evidence that PET drink bottles can leach substances into the contents that mimic the sex hormone estrogen – phthalates and antimony – has put PET bottles in the crosshairs also of scientists worried about their health safety.

This is an updated version of
Fewer Toxins in Toyland that incorporates recently stalled legislation in California aimed at protecting young children from risky chemicals.
This holiday season, parents shopping for children can rest just a tad easier because of a recent California law restricting the use of toxic phthalate plasticizers in toys and childcare products made of plastic. Additional legislative efforts to rein in two other classes of chemicals suspected of posing health risks to youngsters, bisphenol A and halogenated flame retardants, emerged this year in the State Senate, although neither met with success.
But, perhaps the best news is that California has enacted laws establishing a groundbreaking precautionary approach to the oversight of chemicals that should soon make such painstaking chemical-by-chemical regulation a thing of the past.

So You Like that “New Car Smell?” Think again.
(#10 of the Plastic Plague Series)
by Sarah S. Mosko, Ph.D.
Your 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 »

Disneyland Boasts Eco-Friendly Policies
But could it be doing more?
by Sarah S. Mosko, Ph.D.
Walt Disney designed Disneyland Resort for enchantment, an oasis free of cares where everything wondrous seems possible. Worries over the park’s environmental impact were probably not at the forefront of his mind, although he is often quoted for voicing appreciation that natural resources are not inexhaustible and that nature must be preserved for future generations.
But the environment is in a lot more trouble today than it was when Disneyland opened in 1955, so it’s fair to ask, “How green is the Happiest Place on Earth today?”
Disneyland is really akin to a small city, employing 20,000 employees and passing double that many guests through the turnstiles daily. Entertaining, feeding and managing the waste of a mob that size in an environmentally responsible fashion is no easy task.
Evironmentality is the Disney trademark program that aims to keep Walt Disney’s conservation legacy alive through diverse environmental policies, some visible to parkgoers. For example, the lagoon scenes in the recently opened Nemo Submarine Voyage were colored using crushed glass from discarded bottles, and the subs are propelled by an innovative zero-emission magnetic coil system, eliminating the need for hundreds of thousand of gallons of diesel fuel each year.

Toxins in Toyland
A Scientist’s Timely Caveat Emptor
By Sarah S. Mosko, Ph.D.
Scientists are concerned about toxins in toys.
It’s easy to blame China for the recent brouhaha over popular imported toys containing lead, a toxic heavy metal known to cause a myriad of developmental abnormalities including inattention/hyperactivity, learning deficiencies and delayed growth.
After all, the month of August 2007 alone saw a spate of five separate recalls by the Consumer Product Safety Commission (CPSC) for Chinese-made toys and another by Toys Я Us for imported vinyl baby bibs, all illegally containing lead in paints or inks (lead brightens the colors). Well-known toy importers Mattel, Fisher-Price and Schylling all made the recall lists.
Yet, a number of respected scientists are voicing strident concerns about toys and other products for children that contain other perfectly legal chemicals that might also be unsafe for young children. The discovery of lead in toys could be just the tip of an iceberg. What follows is an overview of what, beyond lead, has some scientists worried. Read the rest of this entry »

San Francisco Nixes Plastic Toxins
(#9 of the Plastic Plagues Series)
by Sarah Mosko, Ph.D.
The City of San Francisco was first to nix some toxic plastics. Photo courtesy of my.sfgov.org
As of Dec. 2006, plastic toys and childcare products containing either of two chemicals known to disrupt sex hormones will no longer be manufactured, distributed or sold in San Francisco.
One targeted substance is bisphenol-A, the building block of polycarbonate plastics (#7) used to make some baby bottles, teethers and toys. It is an estrogen mimic that has been linked to miscarriage, birth defects, diabetes and prostate cancer. Leaching of bisphenol-A from polycarbonate bottles or containers into the contents has been documented.
Also banned are several plasticizers called phthalates added to PVC (#3, polyvinyl chloride) plastic products to make them soft and squishy. Many children’s toys and teethers contain phthalates that can migrate out since they’re not chemically bonded to the plastic polymer. Phthalates interfere with testosterone during fetal life, and exposure has been linked to abnormal 
reproductive organ development, infertility, premature breast development, shortened pregnancy, and asthma. Read the rest of this entry »

Plastics Damaging to Health: fetuses and children particularly at risk
by Sarah S. Mosko, Ph.D.
The Environmental Working Group reports that toxic fire retardants (PBDEs) are found in mother's milk.
Plastics can pose threats to human health at all stages in our life cycles, with specific risks varying with the type of plastic.
In the process of converting petroleum or natural gas into plastic, toxic chemicals can be released into the air and water supply. For example, vinyl chloride, a known carcinogen, is used to make polyvinyl chloride (PVC) plastics. A chemical called perfluorooctanaote (PFOA) used in the production of plastic-coated non-stick cookware is also carcinogenic.
An assortment of “additives” is often needed to lend particular characteristics to a product. Many items, like computer casings and hair dryers, require flame retardants because plastics are highly flammable. Read the rest of this entry »

Plastics – an Unhealthy Habit?
(#6 of the Plastic Plague Series)

Plastics are lightweight, flexible, durable and can be molded into just about anything. They fill our toy chests, refrigerators, medicine cabinets and desk tops. Since the explosion of consumer plastics in the 1950s, we have come to rely on them to get us through our busy lives. But, there is a dark side to plastics as well, and it has to do with our health.
