生态毒理学生态毒理学

背景情况:

微塑料 (MP) 污染在淡水生态系统中越来越令人担忧.
了解鱼类的MP摄入对于评估生态风险至关重要.
喜马拉雅河流,如阿拉克南达河,在水污染方面没有得到充分的研究.

研究的目的:

调查五种不同养习惯的鱼类中的微塑料摄入.
为了确定摄入的微塑料的类型和化学成分.
为了确定喜马拉雅河流鱼中微塑料污染的基线.

主要方法:

用过氧化消化和真空过来分析鱼的肠道含量是否含有微塑料.
微塑料被微观地量化.
微塑料的化学鉴定使用减弱总反射率-里埃变换红外光谱法 (ATR-FTIR) 进行.

主要成果:

所有五种鱼类 (Schizothorax richardsonii,Crossocheilus latius,Cyprinus carpio,Tor chelenoid,Botia horii) 都出现了微塑料污染的情况.
微塑料的摄入率与鱼类的养习惯有很大差异.
草食鱼Tor chelenoid的摄入微塑料量最高.
纤维是占主导地位的微塑料类型 (66%).
确定的微塑料包括高密度聚乙烯 (HDPE),聚烯 (PP) 和聚.

结论:

喜马拉雅河阿拉克南达河中的鱼类接触并摄入微塑料.

Freshwater Microbial Ecology

Freshwater Microbial Ecology

Freshwater systems such as streams, rivers, and lakes exhibit distinct physical and biological characteristics that influence their microbial communities. These environments are broadly categorized into lotic systems—those with flowing waters like streams and most rivers—and lentic systems, which include still or slow-moving waters such as lakes, ponds, and marshes.In lentic systems, phytoplankton drive primary production, generating autochthonous organic carbon. In contrast, lotic systems...
