چکیده

Phthalate pollution in soil and vegetables plastic agricultural greenhouses has attracted wide concern. Investigating airborne phthalates this environment can improve understanding of air-soil or air-vegetable phthalate migration. However, studies greenhouse air are rare. To fill gap, 25 gas-phase 23 particle-phase samples were collected from 12 typical Shaanxi. 16 types measured by a gas chromatography-mass spectrometry system (GC-MS) to analyse their features variations. Results showed that the greenhouses, median concentration sum sixteen type (?16 phthalates) was 5305 ng m?3, with 5th-95th value 1214–9616 m?3. Phthalates over 100 times higher than levels samples. Air concentrations those control groups (P < 0.05). bis (2-ethylhexyl) (DEHP) di-n-butyl (DnBP) accounted for 66.9% 29.3% total ?16 concentrations, respectively. winter 1.1–5.3 summer respectively Gas-particle partition coefficients (KP) values DEHP (median 1.52 × 10?4 m3 ?g?1) KP DnBP (0.60 ?g?1). Log-transformed linear correlated reciprocal temperatures,
