Validation of road traffic noise and prediction of traffic increases along a highway in Hungary using noise mapsNARA Subscribed
In urban regions of Europe, road traffic noise ranks as the second most significant environmental stressor, following air pollution. This study measures urban road traffic noise using a noise map that is validated by in situ noise measurements, and it predicts a future scenario for increased traffic in 2030 by altering the traffic composition and overall vehicle count whilst evaluating the noise exposure at building façade poi...
The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is widely used in agricultural systems, raising concerns about its potential genotoxic effects on non-target organisms. This cross-sectional observational field study evaluated nuclear abnormalities in exfoliated buccal mucosa cells from 36 grazing cattle maintained on a farm where 2,4-D was routinely used in Goiás, Brazil, and investigated their relationship with physiologi...
Urban freshwater ecosystems are increasingly exposed to mixtures of pollutants, including per- and polyfluoroalkyl substances (PFAS). However, their ecological effects remain poorly understood, especially in tropical regions with limited sanitation infrastructure. This study investigated PFAS contamination, water quality, and microbial community structure in Pampulha Lake, a tropical urban reservoir in southeastern Brazil. Spa...
Electrochemical biosensors for saxitoxin detection: advances, limitations, and challenges for market transitionNARA Subscribed
Saxitoxins, produced by freshwater cyanobacteria and marine dinoflagellates, block neuronal sodium channels and can cause paralysis or death. They contaminate drinking water, bioaccumulate in aquatic organisms, and pose serious health risks. Conventional detection methods, though reliable, are costly, time-consuming, and require specialized personnel, limiting rapid or on-site use. Biosensors have emerged as attractive alterna...
Hydrology and water quality are innately linked, as flow dynamics control the transport of pollutants within river systems. Consequently, the timing of sample collection in water quality monitoring programs strongly influences the accuracy of estimated pollutant loads. To minimise error, concentrations should be sampled across the hydrograph, capturing the rising limb, peak, and falling limb, to reflect the dynamic nature of p...
