Abstract

Background Di-(2-ethylhexyl) phthalate (DEHP) is a common plasticizer used in industrial and diverse consumer products. Animal studies indicate DEHP caused developmental, reproductive, and hepatic toxicities. However, human studies of the potential effects of DEHP are limited.Methods The exposed site with a history of over 20 years of waste plastic recycling was located in Hunan Province, China. The reference site without known DEHP pollution source was about 50 km far away from the exposed site. In this study, 181 workers working in plastic waste recycling and 160 gender-age matched farmers were recruited. DEHP concentrations in water and cultivated soil samples, serum thyroid-stimulating hormone, malondialdehyde (MDA), superoxide dismutase (SOD), urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG), and micronuclei frequency in human capillary blood lymphocytes were analyzed.Results Mean levels of DEHP were greater in environment at the recycling site than at reference site (industry wastewater for the exposed: 42.43 μg/l; well water: 14.20 vs. 0.79 μg/l, pond water: 135.68 vs. 0.37 μg/l, cultivated soil: 13.07 vs. 0.81 mg/kg, p < 0.05 for all). The workers had higher median levels of MDA (3.80 vs. 3.14 nmol/ml) and urinary 8-OHdG (340.37 vs. 268.18 μmol/mol creatinine) and decreased SOD activities (112.15 vs. 123.82 U/ml) than the reference group (p < 0.01 for all). Multivariate analysis revealed that the history of working in waste plastic recycling was an independent risk factor for the increased urinary 8-OHdG levels in the male workers (p < 0.01).Conclusions The occupational DEHP exposure might contribute to oxidative deoxyribonucleic acid damage in the male workers.

  • Additional phthalates may be added in reprocessing recycled plastics as well as in a later stage of production, and these are generally not removed from recycling of household plastic waste.

    “Additional phthalates may be added in reprocessing recycled plastics (Hahladakis et al., 2018) as well as in a later stage of production (e.g.labelling and gluing), which are generally not removed from recycling of household plastic waste (Wang et al., 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
