Global Garbage Newsletter for January 16, 2014 Marine litter (marine debris) and plastic pollution *** plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0085433 Rochman CM, Hentschel BT, Teh SJ (2014) Long-Term Sorption of Metals Is Similar among Plastic Types: Implications for Plastic Debris in Aquatic Environments. PLoS ONE 9(1): e85433. doi:10.1371/journal.pone.0085433 Abstract Concerns regarding plastic debris and its ability to accumulate large concentrations of priority pollutants in the aquatic environment led us to quantify relationships between different types of mass-produced plastic and metals in seawater. At three locations in San Diego Bay, we measured the accumulation of nine targeted metals (aluminum, chromium, manganese, iron, cobalt, nickel, zinc, cadmium and lead) sampling at 1, 3, 6, 9 and 12 months, to five plastic types: polyethylene terephthalate (PET), high-density polyethylene (HDPE), polyvinyl chloride (PVC), low-density polyethylene (LDPE), and polypropylene (PP). Accumulation patterns were not consistent over space and time, and in general all types of plastic tended to accumulate similar concentrations of metals. When we did observe significant differences among concentrations of metals at a single sampling period or location in San Diego Bay, we found that HDPE typically accumulated lesser concentrations of metals than the other four polymers. Furthermore, over the 12-month study period, concentrations of all metals increased over time, and chromium, manganese, cobalt, nickel, zinc and lead did not reach saturation on at least one plastic type during the entire 12-month exposure. This suggests that plastic debris may accumulate greater concentrations of metals the longer it remains at sea. Overall, our work shows that a complex mixture of metals, including those listed as priority pollutants by the US EPA (Cd, Ni, Zn and Pb), can be found on plastic debris composed of various plastic types. plosone.org/article/fetchObject.action?uri=info%3Adoi%2F10.1371%2Fjournal.pone.0085433&representation=PDF micro2014.sciencesconf.org/?lang=en International workshop on fate and impact of microplastics in marine ecosystems micro2014.sciencesconf.org/conference/micro2014/pages/Book_of_abstracts_MICRO2014.pdf Book of abstracts and final programme omdt.org/2014/01/14/rapid-response-help-needed/ Rapid Response Help Needed!

Due to the recent storms and weathering, the dock has begun to break up into thousands of pieces of polystyrene foam which have spread across the beach, from Cape Arago to Bastendorff Beach. Volunteers are needed every day to help pick up the debris as it poses a significant threat to wildlife. Volunteers will work with the Coos Bay Chapter of the Surfrider Foundation and OPRD on this effort. marinedebrisblog.wordpress/2014/01/15/learning-about-%ca%bbopala/ Learning about ʻōpala! January 15, 2014 by NOAA Marine Debris Program By: Andrea Kealoha Yesterday, staff from the NOAA Marine Debris Program collaborated with the Papahānaumokuākea Marine National Monument and the Polynesian Voyaging Society to teach 2nd and 3rd grade Hawaiian immersion students about the negative impacts of marine debris. The students learned about the Monument, one of the largest marine conservation areas in the world, and dissected albatross boluses filled with fishing line and plastics. pressherald/blogs/undercurrents/239595181.html You Can(t?) Recycle That Friday January 10, 2014 | 07:56 AM Posted by Harold Johnson (NOTE: This post has been updated & amended on January 15, 2014. Additions noted in italic.) Over the holidays you may have read this article on wrapping paper being/not being recyclable. The confusion isn’t limited to wrapping paper. It permeates the entire recycling industry. Can yogurt tubs be recycled? What about bottle caps? Can paper envelopes with plastic windows be recycled? What about laminated paper? How about colored plastic jugs? Broken glass? Rusted steel? The reason for the confusion is simple -- different recycling companies are trying different ways to get more of the good stuff from us. pressherald/blogs/undercurrents/239903881.html A Year in the Life of the Ocean Monday January 13, 2014 | 08:28 AM Posted by Harold Johnson It’s hard to believe that a year has gone by since my first blog post for the Press Herald. It’s been a joy & an honor to write, and I look forward to the future here! I wanted to pause and look back on the year. The ups & downs. The beauty of our coast & our ocean. The threats it faces. The way it connects us and weaves through our lives -- even sometimes without our knowing it. We live in an era of depleted fisheries and plastic waters. Of changing coastlines that reveal long-buried secrets. An era of uncontained consumerism & polymer lies.
