Pollution and biodegradation of hexabromocyclododecanes: A review

Ling Huang, Syed Bilal Shah, Haiyang Hu, Ping Xu, Hongzhi Tang

《环境科学与工程前沿（英文）》 2020年 第14卷 第1期 doi: 10.1007/s11783-019-1190-8

摘要： • Bioremediation is the most cost-effective approach for degradation of HBCDs. • Bacteria or bacterial consortia are used in the cases of bio-augmentation. • Microbes combined with phytoremediation increase the remediation efficiency. Hexabromocyclododecanes (HBCDs) are the most common brominated flame-retardants after polybrominated diphenyl ethers. HBCDs can induce cancer by causing inappropriate antidiuretic hormone syndrome. Environmental contamination with HBCDs has been detected globally, with concentrations ranging from ng to mg. Methods to degrade HBCDs include physicochemical methods, bioremediation, and phytoremediation. The photodegradation of HBCDs using simulated sunlight or ultraviolet lamps, or chemical catalysts are inefficient and expensive, as is physicochemical degradation. Consequently, bioremediation is considered as the most cost-effective and clean approach. To date, five bacterial strains capable of degrading HBCDs have been isolated and identified: Pseudomonas sp. HB01, Bacillus sp. HBCD-sjtu, Achromobacter sp. HBCD-1, Achromobacter sp. HBCD-2, and Pseudomonas aeruginosa HS9. The molecular mechanisms of biodegradation of HBCDs are discussed in this review. New microbial resources should be explored to increase the resource library in order to identify more HBCD-degrading microbes and functional genes. Synthetic biology methods may be exploited to accelerate the biodegradation capability of existing bacteria, including modification of the degrading strains or functional enzymes, and artificial construction of the degradation microflora. The most potentially useful method is combining micro-degradation with physicochemical methods and phytoremediation. For example, exogenous microorganisms might be used to stimulate the adsorption capability of plants for HBCDs, or to utilize an interaction between exogenous microorganisms and rhizosphere microorganisms to form a new rhizosphere microbial community to enhance the biodegradation and absorption of HBCDs.

Removal, distribution and plant uptake of perfluorooctane sulfonate (PFOS) in a simulated constructed wetland system

Weichuan Qiao, Rong Li, Tianhao Tang, Achuo Anitta Zuh

《环境科学与工程前沿（英文）》 2021年 第15卷 第2期 doi: 10.1007/s11783-020-1312-3

摘要： Abstract • PFOS was removed by soil adsorption and plant uptake in the VFCW. • Uptake of PFOS by E. crassipes was more than that of C. alternifolius. • PFOS in wastewater can inhibit the removal of nutrients. • Dosing with PFOS changed the soil microbial community in the VFCW. A vertical-flow constructed wetland (VFCW) was used to treat simulated domestic sewage containing perfluorooctane sulfonate (PFOS). The removal rate of PFOS in the domestic sewage was 93%–98%, through soil adsorption and plant uptake, suggesting that VFCWs can remove PFOS efficiently from wastewater. The removal of PFOS in the VFCW was dependent on soil adsorption and plant uptake; moreover, the percentage of soil adsorption was 61%–89%, and was higher than that of the plants uptake (5%–31%). The absorption capacity of Eichhornia crassipes (E. crassipes) (1186.71 mg/kg) was higher than that of Cyperus alternifolius (C. alternifolius) (162.77 mg/kg) under 10 mg/L PFOS, and the transfer factor of PFOS in E. crassipes and C. alternifolius was 0.04 and 0.58, respectively, indicating that PFOS is not easily translocated to leaves from roots of wetland plants; moreover, uptake of PFOS by E. crassipes was more than that of C. alternifolius because the biomass of E. crassipes was more than that of C. alternifolius and the roots of E. crassipes can take up PFOS directly from wastewater while C. alternifolius needs to do so via its roots in the soil. The concentration of 10 mg/L PFOS had an obvious inhibitory effect on the removal rate of total nitrogen, total phosphorus, chemical oxygen demand, and ammonia nitrogen in the VFCW, which decreased by 15%, 10%, 10% and 12%, respectively. Dosing with PFOS in the wastewater reduced the bacterial richness but increased the diversity in soil because PFOS stimulated the growth of PFOS-tolerant strains.

摘要：

传统工业优化往往仅限定在工业系统内，限制了优化的潜力。适当扩展系统的边界，将有助于对复杂系统进行更为精确的分析，从而提高工业系统的效率和盈利能力。自然生态系统在物质和能源短缺的情况下，已经进化了数十亿年，生态学家发展了众多的分析工具和指标来表征生态系统的基本运行原理。这些原理为克服传统工业优化技术的瓶颈提供了新的解决方案。具体地说，基于生态原理，通过模仿生态系统中发现的基本功能角色，工业系统可以实现类生态系统的高效组织运行。本文对中国典型钢铁企业的水网络分别采用传统优化模型与基于生态原理驱动的改进模型进行了优化。工业实例研究表明，采用传统优化模型的水网络优化后，可实现新水消耗、废水排放、综合用水成本分别降低23%、29% 和20%；采用基于生态原理驱动的改进模型，水网络优化后，则可使新水用量和综合用水成本进一步降低21%和25%，并实现废水零排放。研究结果表明，基于生态原理驱动的改进优化模型更有利于实现工业系统的可持续发展。

Microbial community and functional genes in the rhizosphere of alfalfa in crude oil-contaminated soil

Yi ZHONG, Jian WANG, Yizhi SONG, Yuting LIANG, Guanghe LI

《环境科学与工程前沿（英文）》 2012年 第6卷 第6期   页码 797-805 doi: 10.1007/s11783-012-0405-z

摘要： A rhizobox system constructed with crude oil-contaminated soil was vegetated with alfalfa ( L.) to evaluate the rhizosphere effects on the soil microbial population and functional structure, and to explore the potential mechanisms by which plants enhance the removal of crude oil in soil. During the 80-day experiment, 31.6% of oil was removed from the adjacent rhizosphere (AR); this value was 27% and 53% higher than the percentage of oil removed from the far rhizosphere (FR) and from the non-rhizosphere (NR), respectively. The populations of heterotrophic bacteria and hydrocarbon-degrading bacteria were higher in the AR and FR than in the NR. However, the removal rate of crude oil was positively correlated with the proportion of hydrocarbon-degrading bacteria in the rhizosphere. In total, 796, 731, and 379 functional genes were detected by microarray in the AR, FR, and NR, respectively. Higher proportions of functional genes related to carbon degradation and organic remediation, were found in rhizosphere soil compared with NR soil, suggesting that the rhizosphere selectively increased the abundance of these specific functional genes. The increase in water-holding capacity and decrease in pH as well as salinity of the soil all followed the order of AR>FR>NR. Canonical component analysis showed that salinity was the most important environmental factor influencing the microbial functional structure in the rhizosphere and that salinity was negatively correlated with the abundance of carbon and organic degradation genes.

摘要：

水是一种有限而宝贵的资源。新加坡的国家水源有4种补给方式，其中之一是自然降水。雨水径流会收集污染物，并将其富集到排水系统和水库中。在当地雨水径流中发现的主要富营养污染物包括硝酸盐和磷酸盐，这些富营养污染物可能导致富营养化。在有植物存在的情况下，生物滞留系统可以有效去除这些污染物。本文探讨了植物特性对雨水径流中营养性污染物的植物修复作用，并将其应用于生物防护系统中。所研究的植物物种在叶绿素含量、叶片绿色的浓度、生物量的产生以及硝酸盐和磷酸盐去除方面表现出了差异。一般而言，干生物量与硝酸盐和磷酸盐的去除程度相关（r = 0.339~0.501）。本地树种的根、叶和总干生物量显示出与硝酸盐去除程度之间的中等至强相关性（r 分别为0.811、0.657和0.727）。速生植物的叶片干生物量与两种污染物的去除程度也显示出中等至强相关性（r 分别为0.707和0.609）。低生长植株的根系生物量与磷的去除有很强的相关性（r = 0.707），但与硝酸盐去除的相关性较弱（r = 0.557）。这些结果对于选择用于生物滞留系统的植物是有价值的。
