Polybrominated diphenyl ethers in urban Jinan, eastern China: Characterization, source identification, and respiratory exposure assessment

چکیده
In order to assess the characteristics of polybrominated diphenyl ether (PBDEs) in atmosphere urban Jinan, eastern China, gas phase and PM2.5 were hereby sampled July 2020. The concentration composition 11 PBDEs obtained. Human exposure was evaluated by daily calculation method. During observation period, average ∑ PM 2.5 214.8±31.3 pg/m 3 , that low-PBDEs 119.1±2.1 BDE209 95.8±15.4 . Among 10 low-PBDEs, highest single content BDE99, followed BDE47, accounting for 43%. PCA showed main sources Jinan Penta-BDEs Deca-BDEs. respiratory children higher than adults, potential risk should be taken seriously.

In this paper, the method of simultaneous determinations of methoxylated polybrominated diphenyl ethers and polybrominated diphenyl ethers in dairy products from China was investigated. PBDEs are widely used brominated flame retardant, which are increasingly reported in the environment. MeO-PBDEs are structural analogs to PBDEs, and reported as natural products and novel pollutants present in t...

Eleven house dust samples were collected in Beijing to quantify 42 different polybrominated diphenyl ethers (PBDEs). Total PBDEs concentrations ranged from 140 to 1,300 ng g(-1). The dominant PBDEs congener identified was BDE 209, which made up more than 70% of all PBDEs congeners. Concentrations of PBDEs in Chinese house dust were lower than in other countries. The most polluted areas were ele...
متن کاملPolybrominated diphenyl ethers: occurrence, dietary exposure, and toxicology.
Polybrominated diphenyl ethers (PBDEs) are used as flame retardants in plastics (concentration, 5--30%) and in textile coatings. Commercial products consist predominantly of penta-, octa-, and decabromodiphenyl ether mixtures, and global PBDE production is about 40,000 tons per year. PBDEs are bioaccumulated and biomagnified in the environment, and comparatively high levels are often found in a...

Introduction Polybrominated diphenyl ethers (PBDEs) are a class of flame retardants that were added to thousands of consumer products, such as thermoplastics, electronic equipment, and textiles (Hale et al., 2001).Research has revealed that municipal sewage could be a significant source of PBDEs contamination that is ubiquitous throughout the environment (North, 2004; Song et al., 2006). The Pe...

Polybrominated diphenyl ethers (PBDEs) have been widely used in the United States and worldwide as flame retardants. Recent PBDE production figures show that worldwide use has increased. To determine whether fish consumption is a source of PBDE exposure for humans, a cross-sectional epidemiologic study of New York and New Jersey urban anglers was conducted during the summers of 2001-2003.
