These birds probably died of starvation since their stomachs were full of the plastic from the nearby collection of plastic pollution known commonly as the Great Pacific Garbage Patch. The albatross are unintentionally killing their young by feeding them plastic, mistaking the colorful bits for real food. What does this have to do with YOU and ME? First, that is our waste out there. And secondly, we are also being killed by plastic, just like the albatross. Though we are not in acute danger of dying with bellies full of bottle caps and lighters, we are poisoning ourselves with plastic over time. The seminal book on the threats of plastic poisoning to our survival is called Our Stolen Future. Another excellent book about the chemical dangers lurking in everyday plastic products is aptly called Slow Death by Rubber Duck. Your food is contaminated with toxic chemicals from plastics. These chemicals you are eating and drinking are changing you on a cellular level, altering your chromosomes in ways that can lead to infertility, obesity, and cancer. For women, estrogenic mimicking chemicals can cause breast cancer; for men, these chemicals cause prostrate cancer, reduced penis and testicle size and low testosterone. These threats are not hypothetical. They have been proven in the lab and demonstrated in real world studies. One of the most important studies on BPA was a Rhesus Monkey study (Patricia Hunt, University of Washington). We share 95% of our DNA with Rhesus monkeys so when they are shown to have genetic damage from BPA, we can be pretty sure the same thing is happening to us. The study provides the strongest evidence yet that estrogen-like chemicals like BPA alter chromosomes, increasing the risk of birth defects and miscarriages. The study used levels of BPA similar to those to which humans are exposed though our food and drink and many consumer products including receipts. The study showed that cellular damage can hit three generations at once. BPA can affect a pregnant mother, her unborn fetus, and if that fetus is female, that fetus's future offspring. http://dx.doi.org/10.1073/pnas.1207854109 http://www.pnas.org/content/109/43/17525.full.pdf+html http://www.pnas.org/content/109/43/17525.full.pdf+html?with-ds=yes

Deakin University scientists are part of the international research team led by Professor Vincent Laudet at the Institute of Functional Genomics of Lyon (ENS de Lyon, CNRS, France) that has discovered a new pathway for bisphenol A (BPA) to spread through the body via a protein known as ERRy (estrogen-related receptor), which plays an important role in metabolism. The involvement of ERRy adds weight to the possibility that BPA could be a cause of obesity and diabetes. ?We know that there are links between BPA exposure and diabetes and obesity but we do not know how it works. With what we have discovered about this new receptor we may well have found the missing link,? said Dr Yann Gibert, a researcher with Deakin?s Metabolic Research Unit. ?Before now it was believed that BPA only affected estrogen receptors and therefore only had an impact on this hormone function. Now that we have found this new receptor we can expand the targets of further research to developmental effects and metabolism.? The results of this study, published in The Journal of the Federation of American Societies for Experimental Biology, add to the growing international evidence of the health risks associated with BPA, that include breast cancer, reproductive disorders, brain function and inner ear development. http://dx.doi.org/10.1096/fj.13-240465

BPA, an endocrine disruptor, has been found to cause tremendous health problems. Therefore, there is an urgent need for detecting BPA in a convenient and sensitive manner to ensure water safety. Herein, we develop a fluorescent turn-on BPA probe, named Bisphenol Orange (BPO), which could conveniently detect BPA in a wide variety of real water samples including sea water, drain water and drinking water. BPO shows superior selectivity toward BPA and up to 70-fold increase in fluorescence emission at 580 nm when mixed with BPA in water. Mechanistic studies suggest a plausible water-dependent formation of hydrophobic BPA clusters which favorably trap and restrict the rotation of BPO and recover its inherent fluorescence.

Oceanographer and lead researcher Julia Reisser a PhD candidate at UWA’s Oceans Institute and School of Environmental Systems Engineering, says this information is an important step in quantifying the plastic hazards that threaten Australian species and marine regions. “The high number of small plastics present in our oceans is a toxic threat to marine organisms and environments,” she says. “They contain hazardous ingredients from manufacturing, like Bisphenol A, as well as pollutants adsorbed from the seawater, which are bioaccumulated up the marine food chain. “Until now, we had little idea how much these tiny plastics were present in Australian waters.” Ms Reisser conducted sea surface net tows at 57 locations around Australia, enabling her to collect the characteristics and concentration of marine plastics in Australian waters.
