Multi- and transgenerational effects of environmental chemicals on mollusks: An underexplored experimental design in aquatic (eco)toxicological studies
Environ Pollut. 2024 Apr 27:124058. doi: 10.1016/j.envpol.2024.124058. Online ahead of print.ABSTRACT(Eco)toxicological studies frequently evaluate the effects of chemicals in one life stage of organisms, but the use of these outcomes can only partially estimate populational effects. In this regard, multi- and/or transgenerational studies should be performed in order to provide information on contaminant effects in a populational functioning context. The present review aimed to summarize and critically evaluate the current knowledge regarding multi- and/or transgenerational effects of traditional and emerging environmental...

Determination of emission factors from a landfill through an inverse methodology: experimental determination of ambient air concentrations and use of numerical modelling
In this study, a methodology for the characterization of the emission profiles of the different sources present in landfills for emission factors determination, applying an indirect methodology, is presented. Ambient air concentrations of volatile organic compounds (VOCs), hydrogen sulphide (H2S) and ammonia (NH3) were determined in three potentially emission sources in Can Mata landfill (Hostalets de Pierola, Catalonia, Spain): dumping areas, pre-closed zone and leachate reservoir as well as in biogas, for the determination of emission factors. Multi-sorbent bed and Tenax TA tubes were used for a wide range of VOCs sampli...

Efficiency and Mechanism of Enhanced Norfloxacin Removal Using Amorphous TiO < sub > 2 < /sub > -Modified Biochar
Environ Pollut. 2024 Apr 28:124027. doi: 10.1016/j.envpol.2024.124027. Online ahead of print.ABSTRACTInadequate treatment of antibiotic-contaminated wastewater, including compounds such as norfloxacin (NOR), poses a substantial treat to both ecological safety and human well-being. An innovative approach was devised to address NOR pollution using amorphous TiO2 modified biochar (A-TiO2/BC) prepared via sol-gel impregnation. The resultant had a commendably specific surface area of 131.8 m2/g-1, which was 1.91 times more than the original surface area of unmodified BC. A-TiO2/BC also exhibited abundant hydroxyl and oxygen-con...

Cyanopeptides occurrence and diversity in a brazilian tropical reservoir: exploring relationships with water quality
This study aimed (i) to determine the dynamics of MCs and other cyanopeptides in a tropical reservoir, (ii) to investigate the correlation between peptides and potential cyanotoxin producers (iii) identifying the possible abiotic factors that influence the peptides. We analyzed, monthly, eight MC variants (MC-RR, -LA, -LF, -LR, -LW, -YR, [D-Asp3]-RR and [D-Asp3]-LR) and other peptides in 47 water samples collected monthly, all season long, from two sampling sites in a tropical eutrophic freshwater reservoir, in southeastern Brazil. The cyanopeptides were assessed by liquid chromatography-tandem mass spectrometry (LC-MS/MS)...

Daily Scale Air Quality Index Forecasting using Bidirectional Recurrent Neural Networks: Case Study of Delhi, India
Environ Pollut. 2024 Apr 27:124040. doi: 10.1016/j.envpol.2024.124040. Online ahead of print.ABSTRACTThis research was established to accurately forecast daily scale air quality index (AQI) which is an essential environmental index for decision-making. Researchers have projected different types of models and methodologies for AQI forecasting, such as statistical techniques, machine learning (ML), and most recently deep learning (DL) models. The modelling development was adopted for Delhi city, India which is a major city with air pollution issues simialir to entire urban cities of India especially during winter seasons. Th...

Experimental and simulation studies on the improvement of coal dust pollution by an aqueous solution of sodium α-alkenylsulfonate and amino acid-based surfactants
Environ Pollut. 2024 Apr 27:124041. doi: 10.1016/j.envpol.2024.124041. Online ahead of print.ABSTRACTThe use of surfactants is crucial for the prevention and control of coal dust pollution in coal mining operation areas, yet there still exist many challenges in the control of coal dust pollution. In this paper, the green biomass-based amino acid surfactant sodium myristoyl glutamate (SMG) and the anionic surfactant sodium α-alkenyl sulfonate (AOS) were selected to investigate the improvement of coal dust wettability by single and binary solutions from the macroscopic and microscopic perspectives. Molecular simulations wer...

Microalgal assemblages response to water quality remediation in coastal waters of Perth, Australia
Environ Pollut. 2024 Apr 27:124017. doi: 10.1016/j.envpol.2024.124017. Online ahead of print.ABSTRACTNutrient reduction is an essential environmental policy for water quality remediation, but climate change can offset the ecological benefits of nutrient reduction and lead to the difficulty of environmental evaluation. Here, based on the records of three lipid microalgal biomarkers and stable isotopes of carbon and nitrogen in two sediment cores from the embayment of Perth, Australia, we reconstructed the microalgal biomasses (diatoms, dinoflagellates and coccolithophores) over the past century and evaluated the ecological ...

Understanding the toxicity risk of antibiotic emissions of aquaculture from the perspective of fluctuations concentration
Environ Pollut. 2024 Apr 27:124024. doi: 10.1016/j.envpol.2024.124024. Online ahead of print.ABSTRACTOrganisms are generally exposed to target contaminant with stable concentrations in traditional ecotoxicological studies. However, it is difficult to truly represent the dynamics and complexity of actual aquatic pollution for risk management. Contaminants may enter nearby aquatic systems in pulsed exposure, thus resulting in that aquatic organisms will be exposed to contaminants at fluctuating concentrations. Especially during the season of summer, due to the changes in displacement or periodic emissions of veterinary antib...

Current status of microbial source tracking applications in constructed wetlands serving as nature-based solutions for water management and wastewater treatment
Environ Pollut. 2024 Apr 27:124076. doi: 10.1016/j.envpol.2024.124076. Online ahead of print.ABSTRACTMicrobial source tracking (MST) has been recognised as an effective tool for determining the origins and sources of faecal contamination in various terrestrial and aquatic ecosystems. Thus, it has been widely applied in environmental DNA (eDNA) surveys to define specific animal- and human-associated faecal eDNA. In this context, identification of and differentiation between anthropogenic and zoogenic faecal pollution origins and sources are pivotal for the evaluation of waterborne microbial contamination transport and the a...
