Marine animals have been known to interact with and become entangled in plastic debris for decades. Despite increasing annual input volumes of waste the natural environment threat this constitutes marine biodiversity, impacts mismanaged generally remain unquantified environmental impact assessments. In paper, we develop a Species Sensitivity Distribution (SSD) approach estimating spatially diff...

Plastic debris within marine environments is an issue of global concern, leading to commitments at international, regional, and national scales remove plastics from the environment prevent further entry. The United Nations (UN) created a framework 17 Sustainable Development Goals (SDGs), with several goals advance environmental dimension sustainable development, country progress tracked by targ...

This paper reexamines policies and outcomes concerning the NY Bight Restoration Plan, and the NY-NJ Harbor Estuary Program (NYNJHEP) precipitated by washups of marine debris and medical wastes in the New York Bight some 25-years ago. Findings indicate progress has been made but further work is necessary. Extensive beach closures have not occurred since 1987-88, although localized closings occur...

Marine debris is recognized as a major threat to biodiversity and can be found ubiquitously even in remote regions, including deep-sea environments. Isla del Coco National Park is known as one of the best protected areas around the world, a preferred diving destination, and is also renowned for large aggregations of pelagic species that attract illegal commercial fisheries. Despite its pristine...

OBJECTIVE Apical extrusion of debris and irrigants during cleaning and shaping of the root canal is one of the main causes of periapical inflammation and postoperative flare-ups. The purpose of this study was to quantitatively measure the amount of debris and irrigants extruded apically in single rooted canals using two reciprocating and one rotary single file nickel-titanium instrumentation sy...

Herein we report on the abundance and composition of floating marine debris (FMD) in coastal waters of the SE-Pacific (off the Chilean coast) during the austral summer 2002. The observed FMD consisted mainly of plastic material (86.9%). Densities of FMD were highest between 20 degrees S and 40 degrees S, corresponding to the main concentrations of human population and activities. Low densities ...

The dominance and persistence of plastic debris in the marine environment are well documented. No information exists in respect to their lifespan in the marine environment. Nevertheless, the degradation potential of plastic litter items remains a critical issue for marine litter research. In the present study, polyethylene terephthalate bottles (PETs) collected from the submarine environment we...

Leatherback sea turtles Dermochelys coriacea are regularly reported in the Mediterranean Sea but rarely reach the northern Adriatic Sea. In the summer of 2009, a well-preserved carcass of an adult female of this species was found dead along the coast of Lido di Venezia. A complete necropsy was carried out, along with evaluation of levels of tissue trace elements. The the post-mortem revealed ac...

Microplastics (plastic debris smaller than 5mm) represent a growing concern worldwide due to increasing amounts of discarded trash. We investigated microplastic debris on sandy shorelines at seven locations in a northern Gulf of Mexico estuary (Mobile Bay, AL) during the summer of 2014. Microplastics were ubiquitous throughout the area studied at concentrations 66-253× larger than reported for ...
