Role of phosphate in microalgal-bacterial symbiosis system treating wastewater containing heavy metals
This study investigated the roles of phosphate on the response of the MABS system to Zn2+. The results showed that the pollutant removal effect in the MABS system was significantly reduced, and microbial growth and activity were inhibited with the presence of zinc ion (Zn2+). When phosphate and Zn2+ coexisted, the inhibition effects of pollutants removal and microbial growth rate were mitigated compared to that of only with the presence of Zn2+, with the increasing rates of 28.3% for total nitrogen removal, 37% for chemical oxygen demand removal, 78.3% for chlorophyll a concentration, and 13.3% for volatile suspended solid...

Serum metabolome perturbation in relation to noise exposure: exploring the potential role of serum metabolites in noise-induced arterial stiffness
Environ Pollut. 2024 Apr 9:123945. doi: 10.1016/j.envpol.2024.123945. Online ahead of print.ABSTRACTNoise pollution has grown to be a major public health issue worldwide. We sought to profile serum metabolite expression changes related to occupational noise exposure by untargeted metabolomics, as well as to evaluate the potential roles of serum metabolites in occupational noise-associated arterial stiffness (AS). Our study involved 30 noise-exposed industrial personnel (Lipo group) and 30 noise-free controls (Blank group). The untargeted metabolomic analysis was performed by employing a UPLC-HRMS. The associations of occup...

Environmental DNA highlights the influence of salinity and agricultural run-off on coastal fish assemblages in the Great Barrier Reef region
Environ Pollut. 2024 Apr 9:123954. doi: 10.1016/j.envpol.2024.123954. Online ahead of print.ABSTRACTAgricultural run-off in Australia's Mackay-Whitsunday region is a major source of nutrient and pesticide pollution to coastal and inshore ecosystems of the Great Barrier Reef. While the effects of run-off are well documented for the region's coral and seagrass habitats, the ecological impacts on estuaries, the direct recipients of run-off, are less known. This is particularly true for fish communities, which are shaped by the physico-chemical properties of coastal waterways that vary greatly in tropical regions. To address t...

Comparison of microplastic type, size, and composition in atmospheric and foliage samples in an urban scenario
Environ Pollut. 2024 Apr 9:123911. doi: 10.1016/j.envpol.2024.123911. Online ahead of print.ABSTRACTThe rising trend of plastic production in last years and the inadequate disposal of related waste has raised concerns regarding microplastic-related environmental issues. Microplastic particles disperse by means of transport and deposition processes to different ecosystems and enter food chains. In this paper, atmospheric deposition and foliage samples of two species (i.e., Hedera helix and Photinia glabra) were collected and analysed for the quantity and identity of microplastics (MPs). A preliminary methodology to treat fo...

6PPDQ induces cardiomyocyte senescence via AhR/ROS-mediated autophagic flux blockage
In conclusion, our research unveils that exposure to 6PPDQ induces ROS overproduction through AhR activation, leading to disruption of autophagy flux and ultimately contributing to cardiomyocyte senescence.PMID:38604309 | DOI:10.1016/j.envpol.2024.123872 (Source: Environmental Pollution)

Back to the future: comparing yeast as an outmoded artificial tracer for simulating microbial transport in karst aquifer systems to more modern approaches
This study evaluates whether a historically used microbial tracer (yeast) which is readily available, inexpensive, and environmentally friendly, but usually overlooked in modern karst hydrogeological studies due to challenges associated with its detection and quantification in the past, can reemerge as a valuable tracer using the latest technology for its detection. Two field-based studies on separate karst systems were carried out during low-flow conditions using a portable particle counter along with flow cytometry measurements to monitor the recovery of the yeast at the springs. Soluble fluorescent dyes were also inject...

Effect of nanobubbles on the mobilization of microplastics in shorelines subject to seawater infiltration
In this study, we explored natural NBs' influence on the mobilization of MPs in shorelines subject to seawater infiltration. Using glass beads as a substrate, a coastal porous environment was constructed through column experiments, and the pump-controlled water flow was used to study the transport of MPs (ranging between 4-25 μm) subject to seawater movement within the substrate. The infiltration of MPs under continuous and transient conditions, as well as the upward transport induced by flood tide, were considered. The role of salinity in the interactions between NBs, MPs, and substrates was evaluated. Salinity altered t...

"The potential contribution of aquatic wildlife to antibiotic resistance dissemination in freshwater ecosystems: A review"
Environ Pollut. 2024 Apr 8:123894. doi: 10.1016/j.envpol.2024.123894. Online ahead of print.ABSTRACTAntibiotic resistance (AR) is one of the major health threats of our time. The presence of antibiotics in the environment and their continuous release from sewage treatment plants, chemical manufacturing plants and animal husbandry, agriculture and aquaculture, result in constant selection pressure on microbial organisms. This presence leads to the emergence, mobilization, horizontal gene transfer and a selection of antibiotic resistance genes, resistant bacteria and mobile genetic elements. Under these circumstances, aquati...
