Blue Vinyl
Blue Vinyl
As we become more informed as time goes on, it seems to annoy people a lot more when yet another product has health hazards. There are so many risks involved in so many things we use, I find it impossible to keep track of all of them. While being informed about many issues is vital, where do we stop? How should we prioritize what is and isn't important? I think one subtle lesson I learned from this experience is that nothing is perfect, and we should weigh the costs and benefits of the products we consume, or the things we endorse.
Blue Vinyl
Talking to my roommate today, I began describing in extensive detail about what I had learned from Blue Vinyl. The fact that I knew next to nothing about the hazards associated with PVC frightened me. How could a chemical so pervasive and intrinsic to our lifestyle be ignored so easily? I began to question what else I do not know about the products I am using. As a result, I feel very appreciative that Judith’s documentary brought these issues to light. Access to information is critical to making informed, ethical decisions and as Judith continually asks her family, "if you knew, would you still have purchased the vinyl?" Right to information is a crucial component of environmental justice, and I am thankful for the opportunity to be a more knowledgeable consumer.
However, what most affected about the film was the complexity of the situation. It is not like DDT where there are easily available substitutes. For those homeless women who were provided an affordable house by the Vinyl Institute, vinyl represented the gateway to meeting basic necessities such as shelter. In addition, Judith herself struggled with the high cost of alternatives. I wish everyone could afford straw houses and recycled wood but this is not feasible.
After reporting about the endless health problems inflicting the workers in Louisiana and Italy, my roommate countered that vinyl did not seem to pose any immediate risks to those not living near the factory. I then began recounting PVC’s most dangerous quality-its inability to be recycled. This aspect scares me the most. What we blindly create now will remain a problem for future generations. Even though vinyl may seem like the easiest solution at the present, I hope that our country can learn to approach the chemical industry from a more precautionary perspective.

Blue Vinyl
Unsurprisingly, the documentary included many unsavory facts about vinyl, a material used a tremendous amount in day to day American life. Manufacturers of the polyvinyl chemical were being taken to court under criminal charges in Italy, and it seems that the industry has come under a lot of scrutiny as many countries begin to seek alternatives to PCB, a integral chemical in vinyl, and begin to phase-out the use of vinyl in many industries.
On the surface, the film is great. However, as a viewer, I had a very different reaction to the movie. On an intellectual level, I enjoyed it since I learned a great deal. On an emotional level, I was actually quite upset. I have vinyl on my home. Does my parents purchasing vinyl, making them a consumer of the vinyl industry, make them responsible in any way for the suffering of the towns in Louisiana and Kentucky where vinyl is manufactured? If there is lead in the paint on the exterior of my home and I choose to replace the painted surface with vinyl siding, would I be supporting putting other people's children in danger for the sake of protecting my own?
I feel that because Judith, in a way, guilted her parents into replacing their siding, she was making them feel as if they supported the vinyl industry by choosing one of its products for their home. This sounds a bit harsh and a bit unsettling, and I was certainly unsettled by the end of the documentary. Not enough to want to go to Louisiana and protest the industry, but enough to really become overwhelmed and shut down. After reading Poisoned Profits and watching Blue Vinyl, I'm left wondering what, if anything, I can do. It seems that the chemical industry is causing an outrageous amount of suffering but proves to have its hand supporting too many aspects of life to want to tear it down.
Right now, I'm thinking of all the different ways that the chemical industry is supporting my own life, and wondering how I will be affected later on down the road. I'm beginning to see bit by bit where small changes being taken can amount to large-scale differences in the world. I'm not saying I'm optimistic just yet, but maybe with some discussion on what is being done positively in the world, I'll feel a little better.
Blue Vinyl AND Poisoned Profits Response
Now, about Blue Vinyl- I had seen this movie once before in a class I took my freshman year. The first time, the movie really introduced to me to this concept that materials can be most harmful in their production and disposal. Watching the movie today was a reminder of how dangerous this fact is, but I also saw it through a new light with regards to environmental justice issues, and all the environmental chemistry I have learned last semester and this summer. Judith remarked on the problem that vinyl is just cheaper to produce, which I think is a massive obstacle to overcome. The Shabecoffs touched upon this, not about vinyl specifically, but about the influences from capitalism. They suggested that the government needs to step in and motivate industry to produce and dispose cleanly. I really hope this film helps motivate action like that because it is frightening how such a widely-used product puts human lives on the line.

Relevant to Environmental (not study) Interests

Environmental lead contamination is prevalent in urban areas where soil represents a significant sink and pathway of exposure. This study characterizes the speciation of lead that is relevant to local recontamination and to human exposure in the backyard gardens of Roxbury and Dorchester, MA, USA. One hundred forty-one backyard gardens were tested by X-ray fluorescence, and 81% of gardens have lead levels above the US EPA action limit of 400 mg/g. Raised gardening beds are the in situ exposure reduction method used in the communities to promote urban gardening. Raised beds were tested for lead and the results showed that the lead concentration increased from an initial range of 150 +- 40 mg/g to an average of 336 mg/g over 4 years. The percent distribution of lead in the fine grain soil (less than 100 mm) and the trace metal signature of the raised beds support the conclusion that the mechanism of recontamination is wind-transported particles. Scanning electron microscopy and sequential extraction were used to characterize the speciation of lead, and the trace metal signature of the fine grain soil in both gardens and raised gardening beds is characteristic of lead-based paint. This study demonstrates that raised beds are a limited exposure reduction method and require maintenance to achieve exposure reduction goals. An exposure model was developed based on a suite of parameters that combine relevant values from the literature with site-specific quantification of exposure pathways. This model suggests that consumption of homegrown produce accounts for only 3% of children’s daily exposure of lead while ingestion of fine grained soil (less than 100 mm) accounts for 82% of the daily exposure. This study indicates that urban lead remediation on a yard-by-yard scale requires constant maintenance and that remediation may need to occur on a neighborhood-wide scale.

let me know what you think! also all of the lead values are the total estimated lead contents of the samples, not what was extracted.

Poisoned Profits
Poisoned Profits concludes with a section on corporate reform. The Shabecoff’s write, “Taming corporate power and its abuses will take far more than ineffectual regulatory Band-Aids, fines, and a few prison sentence” (251). Years ago the Shabecoff’s sounded the warning call against the over-powerful position of corporations in American society and the risks associated with treating businesses like people. These points remain pertinent to our country’s current situation. Ironically, before the Gulf oil spill on April 20, BP was a finalist for the Mineral Management Service’s SAFE award. It sadly took another major catastrophe to produce a public outcry, despite environmentalists reporting violations and lack of transparency in these companies for decades. Now the question remains whether or not the new regulations being put into place in Washington will remain simply a “Band-Aid.” The fact the Poisoned Profits did not receive the same controversial reception as Silent Spring in the 1960s worries me. The Shabecoff’s hoped that their book would inspire social action and transform the political structure, but as of yet, it does not seem to have sparked a call to action except within the academic strata. I hope someday this book will make it to mainstream audiences, because I believe it is an important overview of the dangers facing our planet.
Meeting the Shabecoff’s really added to the experience of reading the book. I was shocked to hear the NYTimes fired Philip for being too “pro-environment” but felt inspired to see a couple believe so passionately in these issues and willingly face adversity in order to share their message. Each of the speakers thus far on the JBS program finished by asking us what we plan to do to help the environment. I personally appreciate the challenge, especially since it is not a particular generation’s problem but requires the efforts of all ages and nations.-Tiffany

Plans for Stonehurst Saturday
Judy Fallows of Healthy Waltham, the Wayside fellows and the Waltham Land Trust are eager for your involvement this Saturday, 12-4pm at the community event at Stonehurst. Please let me know if you plan to go for any part.
All is planned already for you. Below is from Judy about your involvement in the activity and transportation options. (See earlier posting on blog about the event itself):
"We are planning the activity, all your students have to do is show up. There will be a couple of options, but the one we like the most is making a bookmark with things they find around the grounds - leaves, flower petals, etc. - and capturing them between clear sheets of contact paper. We will probably also do leaf rubbings, again they will need to hunt around and find suitable leaves. If your students come for a couple of hours, it would be terrific if they could come in shifts, so we have help with the activity throughout the 4 hours. We'll also have them keep an eye on the water station and help people get water to drink.
If some students could be there between noon and 4, that would be great, and if anybody wanted to stay beyond 4 and help with cleanup, I'd be glad to give them a ride back to Brandeis. There will be a shuttle bus (city trolley) going from the top of Moody St, past the common and out to Stonehurst several times that day, as part of the Historic Waltham Days deal. I don't have the schedule yet, but some of your students might be able to hop on the shuttle to get to Stonehurst.
I can discuss more on Thursday morning [at Brandeis garden.]I'll show up at 9 and perhaps can stay for 20 minutes,as I also have to get to Stonehurst to set up there."
Will you let me know if you plan to come, and for what portion?
See you tomorrow at "our" van in EAST lost at 10am, dirty plates and all!

Chicken Jack’s 3-Bean Chili
1 cup dried black beans
½ cup dried Spanish red beans
½ cup dried Italian white beans
2 tablespoons canola or olive oil
1 medium yellow onion, medium dice
1 tablespoon minced garlic
1 jalapeno pepper, seeds removed, medium dice
2 poblano peppers, seeds removed, medium dice
1 red pepper, medium dice
1 tablespoon cumin
1 tablespoon chili powder
1 tablespoon Mexican oregano
1 teaspoon cinnamon
4 cups vegetable broth
4 cups water
16 ounces fire-roasted tomatoes
2 teaspoons kosher salt
1 teaspoon freshly ground black pepper
Soak the beans together overnight. Drain.
In a large soup pot, heat the oil over medium heat. When the oil is shimmering, add the onion, garlic, and jalapeno, poblano and red peppers; cook 5-10 minutes, until soft.
Add the cumin, chili powder, oregano, and cinnamon; cook, stirring, 1 to 2 minutes. Add beans; stir to evenly distribute seasonings, and add broth and water. Raise heat to high and bring to a boil. Reduce heat to a simmer, leaving the pot uncovered; cook for at least 1 hour or until beans are tender to taste.
Add tomatoes. salt and pepper; continue simmering for another 20 to 30 minutes, until the chili has thickened. If at any time the liquid falls below the level of the bean mixture, add more broth or water to cover. Adjust salt and pepper to taste.
Serves 10.
