摘要

Chlorinated paraffins (CPs) are used in many products, including soft poly(vinyl chloride) curtains, which are used in many indoor environments.Health hazards posed by CPs in curtains are poorly understood.Here, chamber tests and an indoor fugacity model were used to predict CP emissions from soft poly(vinyl chloride) curtains, and dermal uptake through direct contact was assessed using surface wipes.Short-chain and medium-chain CPs accounted for 30 by weight of the curtains.Evaporation drives CP migration, like for other semivolatile organic plasticizers, at room temperature.The CP emission rate to air was 7.09 ng/(cm2 h), and the estimated short-chain and medium-chain CP concentrations were 583 and 95.3 ng/m3 in indoor air 21.2 and 172 μg/g in dust, respectively.Curtains could be important indoor sources of CPs to dust and air.The calculated total daily CP intakes from air and dust were 165 ng/(kg day) for an adult and 514 ng/(kg day) for a toddler, and an assessment of dermal intake through direct contact indicated that touching just once could increase intake by 274 fig.The results indicated that curtains, which are common in houses, could pose considerable health risks through inhalation of and dermal contact with CPs.
