Clear plastic bottles or cans made from polycarbonate with bisphenol A leashing into product it contain. Before it was fragile, but chemically stable, indifferent glass. Can we afford to pay with our health (and lives, after all) for this fruit of chemical progress? It damaging everything inside a body, it's just happen to discover some of its symptoms.

Chemical BPA in workers linked to sex problems

By MALCOLM RITTER, AP Science Writer Malcolm Ritter, Ap Science Writer – 2 hrs 1 min ago

NEW YORK – Male factory workers in China who got very high doses of a chemical that's been widely used in hard plastic bottles had high rates of sexual problems, researchers reported Wednesday.

The men in the study experienced BPA levels about 50 times higher than those faced by typical American men, said researcher Dr. De-Kun Li. "We don't know" whether more typical doses have similar effects, he said.

BPA is used in a wide variety of consumer products, including some hard plastic bottles and metal food or beverage cans. Several makers of baby bottles recently said they had stopped using the chemical. Some 90 percent of the U.S. population carries detectable levels in the urine.

The U.S. government recently announced new funding for research into BPA's effects.

Despite the advances in baby bottle technology and safety, there are still many people that do not like to use plastic or polycarbonate bottles to feed their babies. In this case, the best option to go for is to use glass baby bottles. Glass baby bottles have zero BPA and are completely safe to use. You don't have to worry about harmful chemicals leeching into your baby's formula or milk.

Preemptive Strike? Apple Upgrades Mac Computers

The Mac laptop and desktop lineups receive a significant upgrade from Apple as Microsoft prepares to introduce Windows 7

Days before archrival Microsoft is set to release the next major version of its flagship computer operating system Windows, Apple unveiled a significant upgrade to its consumer personal computer lines, including a redesigned entry-level laptop and a desktop machine sporting a huge display. The product announcement comes a day after Apple's (AAPL) earnings report.

Chief among the new releases Oct. 20 is the MacBook, Apple's $999 entry-level laptop usually aimed at students and first-time Mac buyers. The new machine still sports a polycarbonate shell but now it's cut from a single piece of material and has rounded edges. And like the higher-end MacBook Pro, the new MacBook also boasts a long-life battery that lasts seven hours and a light-emitting-diode (LED) display.

Among all the other plastic substances that get into our food, BPA stands out, according to Vandenberg, for its ability to disrupt the functions of hormones -- especially estrogen.

If you want to reduce your exposure to BPA, there are some steps you can take:

Eat less canned food, and more frozen or fresh food. In addition to avoiding BPA, you'll also get more nutrients and less sodium -- both steps toward a healthier diet.

Breastfeed your baby, or use powdered formula instead of cans.

Avoid bottles and plastic containers that are made from polycarbonate (usually marked with a number 7 or the letters PC) and if you want to reduce exposure to phthalates, avoid polyvinyl chloride (marked with a number 3 or PVC).

Concerns over bisphenol A continue to grow

In animals, fetal exposures to BPA can be especially risky, sometimes fostering brain, behavioral or reproductive problems (SN: 9/29/07, p. 202). Canada and some states are moving to ban polycarbonate plastic in baby bottles for that reason. But the new heart data suggest that even adult exposures to BPA might cause harm.

Based on such data, House Committee on Energy and Commerce chairman Henry Waxman (D-Calif.) and the committee’s Oversight and Investigations Subcommittee chairman Bart Stupak (D-Mich.) sent a letter on June 2 to FDA Commissioner Margaret Hamburg. It asks FDA to “reconsider the Bush administration’s position that BPA is safe at current estimated exposure levels.”

More troubling news about BPA

Heart arrhythmias in females and permanent, deleterious modifications of a gene that plays a pivotal role in reproduction are two new problems being linked to bisphenol A. Best known simply as BPA, this chemical is a building block of polycarbonate plastics — the hard, clear type used in kitchenware and baby bottles — and of resins used to line most U.S. food cans.

Data on BPA’s hormonal alter ego first emerged in 1938, when researchers reported the chemical could trigger biological changes normally seen with estrogen. That’s the primary female sex hormone. By the early 1990s, studies showing how strong this estrogen mimic is and how ubiquitous BPA has become began to trickle out — a flow that has since developed into a wholesale torrent.

BPA appears harmful even at concentrations present in the U.S. population,

So people should do what they can to reduce their exposures.

new data hint that people may face far larger BPA exposures than previously thought.

Drinking from Plastic Bottles 'Increases Exposure to Gender-Bending Chemical'

Scientists have demonstrated for the first time that polycarbonate containers release the chemical bisphenol A (BPA) into liquid stored in them.

BPA has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease and diabetes in humans.

Altogether 77 students took part in the study after a seven-day "washout" phase in which they drank all cold beverages from stainless steel bottles in order to minimise BPA exposure.

Study author Karin B. Michels, associate professor of epidemiology at HSPH and Harvard Medical School, said: "We found that drinking cold liquids from polycarbonate bottles for just one week increased urinary BPA levels by more than two-thirds.

They were then given two polycarbonate bottles and asked to drink all cold beverages from the bottles during the next week.

The results showed the volunteers' urinary BPA concentrations increased 69 per cent after drinking from the polycarbonate bottles.

BPA, Chemical Used To Make Plastics, Found To Leach From Polycarbonate Drinking Bottles Into Humans

ScienceDaily (May 22, 2009) — A new study from Harvard School of Public Health (HSPH) researchers found that participants who drank for a week from polycarbonate bottles -- the popular, hard-plastic drinking bottles and baby bottles -- showed a two-thirds increase in their urine of the chemical bisphenol A (BPA). Exposure to BPA, used in the manufacture of polycarbonate and other plastics, has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease and diabetes in humans.

Boston, MA -- A new study from Harvard School of Public Health (HSPH) researchers found that participants who drank for a week from polycarbonate bottles, the popular, hard-plastic drinking bottles and baby bottles, showed a two-thirds increase in their urine of the chemical bisphenol A (BPA). Exposure to BPA, used in the manufacture of polycarbonate and other plastics, has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease and diabetes in humans. The study is the first to show that drinking from polycarbonate bottles increased the level of urinary BPA, and thus suggests that drinking containers made with BPA release the chemical into the liquid that people drink in sufficient amounts to increase the level of BPA excreted in human urine.

Greenhouses are a great addition to your garden no matter how large or small your garden is.

You can use greenhouses to start your plants and vegetables growing early so when the final frost is over your plants are ready to go in the ground. In some parts of the country using a greenhouse can allow you to have 2 (or even more) crops a year.

Greenhouses are not the same today as the ones that you may have seen when you were a kid. You can now get portable greenhouses, greenhouses made with pvc pipes and even collapsible greenhouses.

Avoid plastic water bottles to decrease BPA exposure

A Harvard study released yesterday supports what many public health specialists have long assumed: Hard plastic drinking bottles containing bisphenol A are leaching notable amounts of the controversial chemical into people's bodies.

Researchers from the Harvard School of Public Health found that people who drank for a week from the clear plastic polycarbonate bottles increased concentrations of bisphenol A - or BPA - in their urine by 69 percent.

The study is the first to definitively show that drinking from BPA bottles increases the levels of the chemical in urine, researchers said. It was published on the website of the journal Environmental Health Perspectives.

The Food and Drug Administration has said that products containing BPA are safe and that exposure levels, including those for infants and children, are below those that would affect health. But the FDA's own scientific advisory board criticized agency officials for relying on industry-funded studies to declare the chemical safe.

Is it OK to drink water in plastic bottles

Is it ok to drink water in plastic bottles?

We do not recommend water that is packaged in plastic - even the hard polycarbonate plastic that is popular in 5-gallon jugs that can be taken home and used with a water stand. The reason for our recommendation is migration of plastic compounds, including BPA. Even at room temperature, a very small amount of the plastic in the water container will migrate into the water and increase certain health risks. In some cases, the degree of risk here is very, very small (although more and more concern has been given recently to the hormonal impact BPA may have, especially on children). Nevertheless, since we drink (or should be drinking) water every single day of every single year, any amount of risk here seems worth preventing. Even though glass containers are very inconvenient and more easily broken, we believe that the additional trouble here is worthwhile in terms of health.

Moy Concept

The Moy Concept is a project of a compact car capable of displaying custom graphics and videos through a body made of polycarbonate panels with integrated LCDs and LEDs. The car, designed by Elvis Tomljenovic, was the winner of the contest at the auto(r) conference.

The Moy Concept is targeted at a modern generation who uses technology as a means to express themselves and communicate with others.

This concept, designed by Elvis Tomljenovic, was the winner of the design contest held during the auto(r) automotive design conference.

The body of the car is made of two polycarbonate layers - one outer and one inner - with layers of liquid cristals, LED diodes and electrochromic foil (film) inbetween.

This enables Moy to display both static images and videos, so that it can be used as a new medium of communication or promotion.

The vehicle is powered by batteries that charge electric motors located in the wheels and controlled by drive-by-wire technology.
