Plastics in Marine Environment

Plastics in the Marine Environment

“If all the plastic had been made with oxo-biodegradable technology there would be no ocean plastic garbage patches. ” In the 2012 study published in the Marine Pollution Bulletin “Occurrence of micro-plastics in gastrointestinal tracts of pelagic and demersal fish from the English Channel” it was shown that the majority of plastic particles consumed by the fish were rayon (57.8%) and polyester...

Deterioration of Concrete in Ambient Marine Environment (RESEARCH NOTE)

Structural concrete exposed to marine environment deserves special attention as the diffused sea salts chemically react with harden cement matrix and forms various expansive/leachable compounds leading to loss of material, strength, cracking, spalling etc. This study cover the effect of sea water on the specimens cast from two grades of concrete exposed to simulated marine environment over a ye...

Editorial: (Micro)Plastics and the environment

(Micro)Plastics in the aquatic environment are an issue of emerging concern. However, to date, there is considerable lack of knowledge on the abundance and toxicity of plastic debris in aquatic ecosystems, especially with regard to the freshwater situation. In this editorial, we briefly discuss important aspects of the research on environmental (micro)plastics to stimulate research and call for...

Bio-degradable Plastics- Impact on Environment

Degradation of degradable starch-polyethylene plastics in a compost environment.

The degradation performance of 11 types of commercially produced degradable starch-polyethylene plastic compost bags was evaluated in municipal yard waste compost sites at Iowa State University (Ames) and in Carroll, Dubuque, and Grinnell, Iowa. Masterbatches for plastic production were provided by Archer Daniels Midland Co. (Decatur, Ill.), St. Lawrence Starch Co. Ltd. (Mississauga, Ontario, C...
