More on Vinyl Cholride in Tampa Bay Groundwater

More news stories on the chemical plume spreading in the Tampa Area.  This follows my previous post about Vinyl Chloride in the Groundwater.

Joe Dindino said he has lived on 10th Avenue North for 30 years, and had no idea that chemicals such as dioxane, TCE and vinyl chloride were contaminating the ground in his neighborhood until a news reporter told him.

He wants to know why Raytheon didn't tell residents when its tests showed the plume was moving off the plant's property and under homes.

Toxic Plume in Florida threatens Neighborhood

From the Tampa Bay Online and story about how a toxic plume is threatening the water supply with cancer causing chemicals such as TCE and Vinyl Chloride.

A toxic plume of industrial waste discovered by workers building the Pinellas Trail 17 years ago is now coursing through groundwater under Abel's Azalea neighborhood, beneath parks, playgrounds and hundreds of homes, according to samples drawn from test wells.

Two Vinyl Chloride Links today

The first is from USAToday.com:

Toy Safety Steps back into National SpotLight:  Toy safety emerged as a major issue last year after manufacturers recalled millions of children's products because of lead paint, magnets and other health hazards. Heightened concerns about toys helped win approval of a "toxic toy" law in California, which last October became the first state to ban phthalates, softening agents found in vinyl products that have been linked to reproductive problems in many animal tests and a few human studies.

Baby goes Green:  Organic Toys and Clothes a rising trend: [F}ollowing recent scares about dangerous chemicals in toys and other children’s products, more parents are following Cannon’s early example and searching out natural and organic clothing and accessories for their babies.

Chemical concerns

Iplay’s Cannon said that the U.S. is still catching up to Japan and Europe, which have much stricter standards on the chemicals that can be used in baby products.

The European Union has banned some chemicals that are used to soften the polyvinyl chloride — vinyl — used to make bibs and other items. The typical culprit is lead, already identified as a carcinogen by the Environmental Protection Agency. Wal-Mart, Target and Sears have started programs to get rid of some of these products under pre-ssure from environmentalists who worry children can ingest these chemicals by chewing on vinyl products.

Toxic exposure and autoimmune disease

I was skimming my Google News alerts today and came upon this blog post.  Workers at Risk

Here's the post.

There is mounting evidence from occupational studies of the link between environmental toxins and autoimmune disease. In 2007, scientists from the National Institutes of Health announced a new report on exposures to chemicals and death from autoimmune disease. After studying 300,000 death certificates in 26 states over a 14-year period, researchers found that people who worked with pesticides, textiles, hand painting, solvents (such as TCE), benzene, asbestos, and other compounds were significantly more likely to die from an autoimmune disease than people who were not exposed. Other recent studies likewise show links between working with pesticides, TCE solvents, silica, asbestos, PCBs and vinyl chloride and a greater likelihood of developing autoimmune disease

Yes there is PVC in your Shower Curtain

From over at the Seattle Times an article about greening your bathroom has a section covering PVCs in plastic shower curtains.

Shower showdown

Pop in the shower first, and take a look at your shower curtain. Yikes! If it has mold or grunge (we've all been there), you need to clean it or replace it. Several cleaning-tip Web sites recommend tossing your shower curtain in the washing machine with a couple towels, using detergent and a little bleach. But don't put it in the dryer; let it drip dry.

Most shower curtains are made of polyvinyl chloride (PVC), a plastic that can emit toxics into the environment, especially during production. When you need a new shower curtain, consider a greener, chlorine-free material called polyethylene vinyl acetate (PEVA or EVA).

As part of a toxics-reduction effort, Target currently offers shower curtains and liners made from EVA as well as cloth and is working to achieve a nearly 90 percent non-PVC level in its own brands by spring, according to Target spokesman Joshua Thomas.
