Survey of levels of phthalate ester plasticizers in a sewage lagoon
The sewage lagoon and the receiving stream were grossly polluted as several phthalate ester plasticizers: DMP, DEP, DPhP, DBP, DEHP, DOP and DINP were found present at monthly mean levels of between 24.02 mg/L and 139.25 mg/L in the sewage treatment lagoon and 10.41 mg/L and 80.53 mg/L in the receiving stream.

IJERPH | Free Full-Text | Phthalate Exposure Pattern in Breast Milk
Di-(2-ethylhexyl) phthalate (DEHP), a common plasticizer, has been detected in breast milk in many countries; however, whether phthalate metabolite concentration and the detection rate in breast milk change postpartum is still unknown. We measured phthalate metabolite concentrations in breast milk in the first 6 months postpartum in women enrolled in the E-Da hospital from January to July 2017
Multi-pathway human exposure assessment of phthalate esters and DINCH
Show abstract. 1,2-Cyclohexane dicarboxylic acid, diisononyl ester (DINCH) is a complex mixture of nine carbon branched-chain isomers. It has been used in Europe since 2002 as a plasticizer to replace phthalates such as di (2-ethylhexyl)phthalate (DEHP) and diisononyl phthalate (DINP).
- What phthalates are used in plasticizers?
- Plasticizers—particularly phthalates (PAEs), like di- (2ethylhexyl) phthalate (DEHP), di- iso -nonyl phthalate (DiNP), and di- n -butyl phthalate (DBP) are the most prevalent industrial chemicals applied to consumer products to increase flexibility, transparency, durability and lifespan , .
- How accurate are reference doses for plasticizers?
- The accurate values of reference doses (R f Ds) for most plasticizers are limited, our previous studies predicted R f Ds values for various chemicals, including PAEs and some NPAEs, by the lethal dose (LD 50) or non-observed adverse effect levels (Table S11) , .
- What are plasticizers & npaes?
- Plasticizers like PAEs and NPAEs, the major additives to polyvinyl chloride (PVC) components in electrical and electronic equipment, will be released into the environment during e-waste recycling activities such as acid stripping and physical dismantling , .
- Are phthalate metabolites higher in e-waste sites?
- Zhang et al. found that urinary concentrations of phthalate metabolites in participants living in the e-waste site were significantly higher than in the reference site, different from the present study that evaluated dust and hand wipe samples.
- Are e-waste Dismantlers exposed to plasticizers?
- E-waste dismantlers' occupational exposure to plasticizers, particularly non-phthalate (NPAE) plasticizers, is poorly understood. This study monitored 11 phthalates (PAEs) and 16 NPAEs in dust and hand wipe samples from Central China e-waste workplace and ordinary homes.
- How many class of plasticizers are there?
- Chemicals and reagents Eight class of plasticizers including 11 PAEs, and 16 NPAEs (i.e., sebacates, citrates, adipate, oleates, DiNCH, bis (2-hydroxyethyl) terephthalate (BEHT), and Tri-octyl trimellitate (TOTM)) were determined in the present study.
