Lakes represent an important source of drinking water resource for human beings. The presence of harmful algae blooms can pose a serious threat to lakes water quality. This study explored the feasibility of using eucalyptus plants and leaves extracts for controlling algae proliferation in an aquatic milieu. After 30 days of treatment, the inhibitory efficiencies were 85.8% and 20.9% for treatments planting eucalyptus and eucalyptus leaves extracts, respectively. The synergistic effects of allelopathy and competitive absorption for macro nutrients were attributed to the effective control of algae proliferation in the mesocosm systems. Moreover, the analysis of microbial community structures indicated that eucalyptus plants or leaves extracts had no adverse effect on species diversity and their relative abundance. The choice of using eucalyptus to control algae bloom will be dictated by environmental and economic considerations within a geographical region.

Rainfall events significantly increase dissolved organic matter (DOM) and disinfection by-product (DBP) precursors in the reservoir, threatening water supply security. However, the vertical variations and ecological drivers of DBP precursors in the deepwater stratified reservoir during rainfall events remain poorly understood. This study investigated DOM composition, DBP precursors, nutrients, metals, and algae in the Sanhekou Reservoir under stormwater influence.

Neonicotinoid insecticides residuals pose a threat to aquatic ecosystems and human health. Imidaclothiz, as a novel neonicotinoid pesticide, the metabolic mechanisms in aquatic environments was unclear. This study investigated the degradation characteristics of imidaclothiz in both pure and actual water, and analyzed the photodegradation and hydrolysis metabolites of imidaclothiz in aquatic environments and assessed their toxicity.

This study investigates the bioavailability of humic nitrogen (humic-N) to algae through controlled bioassay experiments. Algae were able to utilize dissolved organic nitrogen (DON) from both humic acid (HA) and fulvic acid (FA), with bacterial co-culture enhancing uptake. Bioavailable nitrogen (BAN) from HA accounted for ~20 % of total nitrogen, whereas FA reached ~45 %, with bacterial presence further increasing FA utilization by about 6-7 %.

Cyanophages are widely distributed viruses that specifically infect blue-green algae and play a critical role as biological control agents in aquatic ecosystems. Despite their ecological importance, the effects of light on cyanophage-host interactions are not fully understood. This study aimed to investigate the role of host photosynthesis in different stages of MaMV-DH01 infection, a novel muscle-tailed cyanophage isolated from Donghu Lake that targets Microcystis aeruginosa FACHB524.
