Marine Debris Occurrence and Treatment: a Review
نویسنده
چکیده
7 Marine debris produces a wide variety of negative environmental, economic, safety, health and 8 cultural impacts. Most marine litter has a very low decomposition rate (as plastics, which are the 9 most abundant type of marine debris), leading to a gradual, but significant accumulation in the 10 coastal and marine environment. Along that time, marine debris is a significant source of 11 chemical contaminants to the marine environment. Once extracted from the water, incineration 12 is the method most widely used to treat marine debris. Other treatment methods have been 13 tested, but they still need some improvement and so far have only been used in some countries. 14 Several extraction and collection programs have been carried out. However, as marine debris 15 keep entering the sea, these programs result insufficient and the problem of marine debris will 16 continue its increase. The present work addresses the environmental impact and social aspects 17 of the marine debris, with a review of the state of the art in the treatments of this kind of waste, 18 together with an estimation of the worldwide occurrence and characteristics. 19

متن کاملThe ecological impacts of marine debris: unraveling the demonstrated evidence from what is perceived.
Anthropogenic debris contaminates marine habitats globally, leading to several perceived ecological impacts. Here, we critically and systematically review the literature regarding impacts of debris from several scientific fields to understand the weight of evidence regarding the ecological impacts of marine debris. We quantified perceived and demonstrated impacts across several levels of biolog...
