To evaluate the pollution level, congener distribution, and human exposure of polybrominated diphenyl ethers (PBDEs) in the atmosphere of Beijing's office buildings, outdoor air samples (particles+gas) were collected from a typical scientific area and PBDEs concentrations were quantified using GC-MS. The results showed that the mass concentrations of PBDEs in the gas phase, PM, and PM were 2.3-78.

- The study assessed concentrations and health risks of heavy metals (Cu, Mn, Pb, Ti, V, Cd, Cr, Co, Mo, Ni) in atmospheric particulate matter and dust in Beijing, collecting samples across all four seasons in 2014.
- Results showed that annual average concentrations of particulate matter were significantly higher than standard limits, with Ti, Mn, and Pb being the predominant metals.
- While the health risk assessment indicated that the levels of these metals were within safe limits, the potential long-term effects on health need to be considered.
Spatial distribution and temporal trends of farmland soil PBDEs: processes and crop rotation effects.
Environ Sci Pollut Res Int
July 2016
The concentration and temporal trend of PBDEs in farmland soil during a circle of crop rotation period within an e-waste dismantling area of South China were investigated. The averaged current concentration of total PBDEs in the farmland soil was averaged 19.1 ± 20.
