DEGRADATION OF POLYMER MATERIALS IN ENVIRONMENT



 

Abstruct: Environmental occurrence of the polymer-based materials (PBMs) and their associated chemical additives have been recognized as an emerging worldwide problem, and their impacts are now a subject of wider scientific and social interest. Production of PBMs  have increased  substantially over the  last few yearsdue to their flexible nature, making them compatible for use in domestic, industrial and developmental purposes. PBMs can  be released into the environment form a variety of sources. The principal introduction routes being general littering, dumping of waste materials,  migrationfrom landfills, emissionduring refuse collection and air-blasting technologies. Once in the environment,  PBMs can be  broken  down by thermal,biological and chemicalprocesses. A numberof literatures to date have addressed the impacts of PBMs in the environment and eventually  on human health. Bulk PBMs are well documented as entanglement and ingestion hazards. Interaction of PBMs with persistent organic pollutants (POPs)  have been shown to biomagnify in food webs causing traumatic injury and cardiovascular diseases in human body. This  review summarizes  up-to-date findings about the source and occurrence of PBMs in both aquatic and terrestrial environments, various degradation processes of PBMs  and most important, the harmful effects of PBMs on environment and human.

 

Keywords: Aquatic, environment, food webs, organic pollutants, terrestrial.
