概括

昆类抗生素 (QNs) 在博海海域普遍存在,造成生态和抗生素耐药性风险. 水产养殖是一个主要的来源,需要对海洋环境进行持续的监测和来源控制.

科学领域:

环境化学环境化学
海洋生态毒理学海洋生态毒理学
公共卫生公共卫生

背景情况:

昆类抗生素 (QNs) 被广泛使用,导致它们在海洋生态系统中被检测为新出现的污染物.
海洋环境面临着越来越多的药品污染,对水生生物和人类健康构成风险.

研究的目的:

调查波海海域的19种昆类抗生素的发生,分布和来源.
评估与沿海水域的QNs相关的生态风险和抗生素耐药性的可能性.

主要方法:

通过博海海域取水样,然后使用先进的分析技术对19个QN进行分析.
基于风险系数 (RQs) 的积极矩阵因子化 (PMF) 和生态风险评估 (ERA) 的来源分配.

主要成果:

检测到15个QN,总度从71.6到336ng/L不等;ofloxacin和marbofloxacin是最丰富的.
在沿海地区,特别是莱州湾和地下水域发现了更高的QN度,这与陆地来源和沉积物动态有关.
水产养殖被确定为主要来源 (∼29.2%),其次是制药,家庭和牲畜投入. 奥夫洛克萨和诺夫洛克萨对藻类构成高风险.

结论:

尽管与以前的研究相比,QN水平下降,但在博海海域仍然存在显著的生态和抗生素耐药性风险.
持续的环境监测和有针对性的源控制策略,特别是水产养殖,对于减轻沿海海洋环境中的QN污染至关重要.

Gene Regulation in Microbial Communities: Quorum Sensing

Gene Regulation in Microbial Communities: Quorum Sensing

Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...
