  • What is dibutyl phthalate (DBP)?
  • Dibutyl phthalate (DBP) is widely used as a plasticizer (in the range of 10–35 %) in polyvinyl chloride (PVC) plastic products, including cosmetics, plastic food packaging, medical devices, building materials, and electronic products , .
  • Are microplastics a long-term source of dibutyl phthalate contaminants?
  • More than 10,000 relevant additives are detected in plastic products on the global market; however, these additives may be transported into environments with microplastics (MPs). Herein, we found that MPs may be a long-term source of dibutyl phthalate (DBP) contaminants in freshwater and seawater.
  • Is DBP hydrolyzed to monobutyl phthalate?
  • DBP has been found in various tissues, despite the fact that it is rapidly hydrolyzed to monobutyl phthalate by non-specific lipases and esterases (Rowland et al. 1977; Tanaka et al. 1978; Foster et al. 1983).
  • What is DBP used for?
  • DBP is widely used as plasticizer in a variety of household industries and consumer products, such as toys, food containers, furniture, cosmetics and personal care products, latex adhesives, cellulose plastics, varnishers, and dye solvents (Stales et al. 1997; Shea 2003; Duty et al. 2005; Heudorf et al. 2007).
  • Are MPs a long-term source of DBP contaminants?
  • MPs may be a long-term source of DBP contaminants in both freshwater and seawater. Dibutyl phthalate (DBP) as a plasticizer has been widely used in the processing of plastic products. Nevertheless, these DBP additives have the potential to be released into the environment throughout the entire life cycle of plastic products.
  • How does plasticizer content affect the release of DBP?
  • The results show that the plasticizer content, UV irradiation, and hydrochemical conditions have a great influence on the leaching of DBP from the MPs. The release of DBP into the environment increases proportionally with higher concentrations of additive DBP in MPs, particularly when it exceeds 15 %.
