ABSTRACT:

Plastic marine debris is increasingly recognised as one of the greatest
threats to global oceans, and the humans who depend on them. This study
documents plastic ingestion in 24 species caught or sold for human
consumption in the South Pacific. Fish were collected from local
fishermen and markets in remote locations, including French Polynesia,
Lord Howe Island and Henderson Island (Pitcairn group). Gastrointestinal
tracts of 126 fish were visually examined and plastic was found in 7.9%
of individual fish and 25% of species. The plastics were mostly
microplastics (fragments, nurdles and rope). There was no significant
difference in plastic ingestion in relation to feeding style, length,
region or species. This is concerning as plastic appears to be
widespread across species, lifestyles and habitats. This is the first
report of plastic in South Pacific fish, raising concerns about the
transfer of pollutants in a region that is largely oceanic and heavily
dependent on seafood. The remote locations of the study also provide
evidence of the widespread nature of this issue.

A recent study has indicated that plastic litter can become fused with rocks and other materials to form a new material: plastiglomerate. This material could very well become a permanent part of the geological record, forever marking humanity?s impact on the world. The results of the report were published in the journal of the Geological Society of America, GSA Today. The material has been discovered before, but it wasn?t until it had washed up on Hawaii?s Kamilo Beach, notorious for its litter, that it was studied and identified. The discovery of the Hawaii sample was made by Captain Charles Moore of the research vessel of Alguita as well as lead author Patricia Corcoran. It is believed that human campfires melted plastic on the beach, causing it to fuse to shells, coral, and sand.

Since plastic is lightweight, strong, durable and buoyant, if not properly discarded, it can enter waterways and eventually the marine environment, where it stays for a long time and becomes a accidental snack for aquatic species. It is estimated that every year 20 million tons of plastic litter enters the ocean, and approximately 100,000 marine mammal individuals are affected by the ingestion of large pieces of plastic. However, unknown number of cases remain undiscovered as many of these animals perish in the open ocean. The most vulnerable marine biota are whales, dolphins and porpoises. Sperm whales are especially prone since their feeding mechanism resembles a vacuum cleaner: they suck the food in their mouth. And unfortunately, sperm whales cannot distinguish plastic bags from one of their favourite diet – squids. Over the years a number of plastic pollution related whale deaths have been reported, and two of the most media-highlighted occurred in the Mediterranean Sea. In 2012, a sperm whale was found washed up with more than 100 pieces plastic bags in its stomach at Mykonos Island in Greece; and in 2013, a sperm whale was also found with 17kg of plastic waste in its gut in Spain.

(http://www.sciencedirect.com/science/article/pii/S0025326X13006048) Abstract: Plastic debris is often ingested by marine predators and can cause health disorders and even death. We present the first assessment of plastic ingestion in Mediterranean seabirds. We quantified and measured plastics accumulated in the stomach of 171 birds from 9 species accidentally caught by longliners in the western Mediterranean from 2003 to 2010. Cory’s shearwaters (Calonectris diomedea) showed the highest occurrence (94%) and large numbers of small plastic particles per affected bird (on average N = 15.3 ± 24.4 plastics and mass = 23.4 ± 49.6 mg), followed by Yelkouan shearwaters (Puffinus yelkouan, 70%, N = 7.0 ± 7.9, 42.1 ± 100.0 mg), Balearic shearwaters (Puffinus mauretanicus, 70%, N = 3.6 ± 2.9, 5.5 ± 9.7 mg) and the rest of species (below 33%, N = 2.7, 113.6 ± 128.4 mg). Plastic characteristics did not differ between sexes and were not related to the physical condition of the birds. Our results point out the three endemic and threatened shearwater species as being particularly exposed to plastic accumulation. Keywords: Plastic ingestion; Seabirds; Shearwaters; Mediterranean Sea

Saido, 1.6 - Ocean Contamination Generated from Plastics, In Comprehensive Water Quality and Purification, edited by Satinder Ahuja, Elsevier, Waltham, 2014, Pages 86-97, ISBN 9780123821836, http://dx.doi.org/10.1016/B978-0-12-382182-9.00005-0. (http://www.sciencedirect.com/science/article/pii/B9780123821829000050) Abstract: For clarification of causes leading to new global chemical contamination from plastics, beach sand and water taken from sites around the world were extracted with dichloromethane and analyzed by selected ion monitoring-gas chromatography/mass spectrometry (SIM-GC/MS). All samples were found to contain the styrene oligomer (SO) (in this study, SO is considered to be a mixture of styrene monomer (SM), )1styrene dimer (SD1), SD2, and styrene trimer (ST)), a mixture consisting of phenylethylene (SM), 2,4-diphenyl-1-butene (SD), and 2,4,6-triphenyl-1-hexene (ST). New global chemical contamination products were clearly shown to be derived from polystyrene (PS) decomposition and/or elution in the ocean, as well as from marine debris plastics whose presence may persist well into the future.
