城市浅水型湖泊底泥污染物释放过程模拟试验研究

通过对城市浅水型湖泊(以宁波东钱湖为例)疏浚后上层底泥污染物释放过程模拟试验研究,分析了环境因子对底泥污染物释放特性的影响及其原因,得出了上覆水营养盐水平、水温和扰动对底泥污染物释放的影响曲线.同时,说明了湖泊内源性有机污染源对湖泊水质存在着潜在的危险性,提出了疏浚施工期间的规避措施,为城市浅水型湖泊底泥疏浚和富营养化治理提供依据.     

海河渤海湾地区沉积物、鱼体样品中多溴联苯醚的水平与分布

从海河、渤海湾水域内采集了沉积物和鱼体(鲫鱼)样品.采用气相色谱/质谱(GC/MS)方法测定了样品中的多溴联苯醚(PBDEs).结果表明,沉积物(以干重计)和鱼体(以干重计)中PBDEs的检出水平分别为0.35～5.53、6.81～35.50 ng/g,其中相对含量较高的PBDEs单体为BDE-28和BDE-47.鱼体内脏组织中PBDEs的检出水平较肌肉组织中的PBDEs要高,表明其更容易富集PBDEs.

Recent advances in the breakdown of microplastics: strategies and future prospectives

Microplastics pollution is becoming a major environmental issue, and exposure to microplastics has been associated with numerous adverse results to both the ecological system and humans. This work summarized the state-of-the-art developments in the breakdown of microplastics, including natural weathering, catalysts-assisted breakdown and biodegradation. Characterization techniques for microplastic breakdown involve scanning electron microscopy, Fourier infrared spectroscopy, X-ray photoelectron spectroscopy, etc. Bioavailability and adsorption capacity of microplastics may change after they are broken down, therefore leading to variety in microplastics toxicity. Further prospectives for should be focused on the determination and toxicity evaluation of microplastics breakdown products, as well as unraveling uncultivable microplastics degraders via cultivation-independent approaches. This work benefits researchers interested in environmental studies, particularly the removal of microplastics from environmental matrix.
