  • Which phthalate is used in non-PVC applications?
  • Short-chain phthalates including dimethyl phthalate (DMP), butyl benzyl phthalate (BBzP), diethyl phthalate (DEP), di-iso-butyl phthalate (DnBP), and di-n-butyl phthalate (DnBP) are commonly used in non-PVC applications (Wittassek et al. 2011).
  • Which phthalate is a priority contaminant?
  • The US EPA (Environmental Protection Agency) has designated several PAEs as priority toxic contaminants, including dimethyl phthalate (DMP), di-2-ethylhexyl phthalate (DEHP), dibutyl phthalate (DBP) and diethyl phthalate (DEP) (Wang et al. 2017).
  • Can microbial degradation remove phthalates from contaminated sites?
  • Compared to non-biological destruction, microbial degradation is rather fast and a promising, cost-effective and environmentally-friendly method for removal of phthalates from contaminated sites. Several studies have shown that bacteria in wastewater can degrade a variety of PAEs in aerobic, anaerobic, and facultative conditions.
  • What phthalates are used in PVC polymer?
  • There are two kinds of phthalates: long-chain phthalates and short-chain phthalates. The long-chain phthalates used in PVC polymer include di (2-ethylhexyl) phthalate (DEHP), di (2-propylheptyl) phthalate (DPHP), di-iso-decyl phthalate (DiDP) and di-iso-nonyl phthalate (DiNP).
  • What is the removal efficiency of DMP and DBP?
  • The removal efficiency of DMP, DEP and DBP were found to be 92.6–97.5, 92.1–99.3 and 93.4–99.1% respectively. Wei et al. (2016) used lab-fabricated hollow fibre nanofiltration (NF) membranes to study the rejection behaviour of a few types of PAEs from water sources, including DMP, DBP, DEP and DEHP.
  • Can phthalate removal treatment improve adsorption of DBP from aqueous solution?
  • Because phthalate removal treatment is directly linked to sorption to solids, improving solid separation would also improve phthalate removal. Wang (2015) investigated the adsorption of DBP from aqueous solution using activated carbon derived from phoenix leaves.
