Phthalates in House and Dormitory Dust: Occurrence, Human Exposure and Risk Assessment was written by Xu, Shen;Li, Chao. And the article was included in Bulletin of Environmental Contamination and Toxicology in 2021.Safety of Dicyclohexyl phthalate This article mentions the following:
Phthalates are one of ubiquitous contaminants in the indoor environment. In this study, we analyzed concentrations and profiles of 9 phthalates in dust samples collected from houses and university dormitories in Nanjing, China. The total concentrations of phthalates in house and dormitory dust ranged from 111.4 to 3599.1μg/g and 86.1 to 1262.3μg/g, resp. Phthalates in house was significantly higher than that in dormitory dust (p < 0.01). Di(2-ethylhexyl) phthalate (DEHP), di-Bu phthalate (DBP) and di-iso-Bu phthalate (DiBP) were the three predominant compounds and accounted for more than 98% of total phthalates in the two microenvironments. The estimated daily intake (EDI) of phthalates, carcinogenic risk (CR) of DEHP, and hazard index (HI) values of DEHP, DBP and DiBP were estimated Except for adults, the CR of DEHP for four subgroups (infants, toddlers, children, and teenagers) had exceeded the limitation, implying that they are at the risk of exposure to DEHP through dust ingestion. In the experiment, the researchers used many compounds, for example, Dicyclohexyl phthalate (cas: 84-61-7Safety of Dicyclohexyl phthalate).
Dicyclohexyl phthalate (cas: 84-61-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Safety of Dicyclohexyl phthalate
