Abstract

This study analyses, the characteristics of plastics as adsorbents and the mechanisms of adsorption between plastics and hydrophobic organic pollutants (HOPs). As the characteristics of the adsorption material, the degree of crystallinity, glass transition temperature, and contact angle with water of the plastics were investigated, and influence factors on the adsorption of various HOPs and the role of plastics as a carrier of HOPs were suggested. As factors affecting the adsorption of organic pollutants onto plastics, the physical and chemical properties of the plastic as adsorption material (i.e. size, polarity, crystallinity, glass transition temperature, presence and type of functional groups, etc.), characteristics of organic pollutants (i.e. concentration, hydrophobicity, surface charge, functional groups, etc.) and water quality (i.e. pH, temperature, ionic strength, coexisting organic pollutants, etc.) are presented. As a result, it was confirmed that organic pollutants are transferred/diffused not only in the organisms but also throughout the world due to plastic wastes in marine.
