Occurrence, distribution and risk assessment of phthalate esters in dust deposited in the outdoor environment of Yazd industrial park using Monte Carlo simulation
AI summary Read the abstract
Researchers assessed the distribution and health risks of eight phthalate esters in outdoor dust at a Chinese industrial park, finding that non-carcinogenic risks remained within acceptable limits and cancer risks were low, with ingestion identified as the dominant exposure route.
In this study, the distribution of eight phthalate esters (PAEs), namely (dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), butyl benzyl phthalate (BBP), bis (2-ethylhexyl) phthalate (DEHP), and di-n-octyl phthalate (DnOP)) were examined across fifteen sampling stations in Yazd industrial Park. All the PAEs in dust deposited in the outdoor environment were analyzed using a Gas-mass chromatography (GC-MS/MS) device. Both probabilistic and deterministic approaches were utilized to assess the non-carcinogenic and carcinogenic health risks for adult occupational population groups. These risks were associated with three exposure pathways: inhalation, ingestion, and dermal exposure to six phthalates in the dust samples. The findings revealed, among the fifteen sampling stations, highest and lowest concentrations of the PAEs in dust deposited in the outdoor environment were observed in S8 and S6, with BEHP (326.21 ± 4.35) μg/g and DMP (0.00 ± 0.02) μg/g, respectively. The total hazard index (HI) values were below one in all samples, indicating that the combined non-carcinogenic health risk from exposure to phthalates via inhalation, ingestion, and dermal pathways is within acceptable levels in each studied area. The total cancer risk (CR) values for BBP across all exposure routes were consistently low, with magnitudes ranging from 10- x 10-15to 10 x 10-11. The order of cancer risk from phthalate exposure in outdoor environments was ingestion > dermal > inhalation. The sensitivity analysis (SA) results indicated that the influential parameters in the carcinogenic risk in adult occupational population groups were concentration for inhalation and dermal pathways, as well as ingestion rate for the ingestion pathway. The result of this study provides new insight in to PAEs pollution and risk assessments related to the dust deposited in the outdoor environment of industrial Park. Furthermore, this finding is beneficial to the controlling the exposure and promoting steps to reduce PAEs contamination and manage health in the industrial area.

Researchers measured phthalate ester (PAE) concentrations in water and sediment along the Torghabeh River in northeastern Iran, finding mean levels of 11,031 ng/L in water and 9,715 ng/g in sediment, dominated by DEHP. While human health risks were generally below thresholds, DEHP and DiBP posed significant ecological risks to aquatic species and elevated dermal exposure concerns for children.

This first comprehensive microplastics assessment of Mashhad, Iran street dust found concentrations ranging from 90 to 530 particles/g, strongly correlated with traffic intensity and population density, with children facing nearly six times higher ingestion exposure than adults. The findings identify urban traffic as a major MP emission source and highlight vulnerable populations facing disproportionate health risks from urban microplastic exposure.
An integration approach for health risk assessment and priority control factor identification of indoor phthalates in a plastic waste recycling plant
AI summary Read the abstract
Workers at a plastic recycling plant in China are breathing in and likely swallowing dust containing phthalates—chemicals from plastics linked to hormone disruption—mostly released during the plastic reprocessing stage, with one chemical called DEHP being the biggest concern. While the cancer risk from this exposure was mostly within acceptable limits, women faced higher health risks than men, and swallowing contaminated dust turned out to be the main way these chemicals entered the body. This research highlights the need for better safety practices in plastic recycling facilities to protect workers from harmful chemical exposure.
