AI Article Synopsis
- In Northern France, rivers are being used to reduce road traffic pollution by improving waterway transport.
- The study focuses on the impact of boat traffic on the resuspension of historically polluted sediments and its effect on water quality.
- Findings indicate that while navigation has a limited effect on dissolved metals and oxygen levels, phytoplankton cycling significantly influences water quality throughout the year.
Article Abstract
In Northern France, channelized rivers facilitate greatly the waterway transport that should still increase in the coming years to replace as much as possible the road traffic, considered as a heavier source of pollution. These rivers are now subjected to the good potential status objectives required by the Water Framework Directive. The impact of the recurrent resuspension by the current boat traffic of polluted sediments (due to strong historical pollution) on the water quality is the main concern of this work. Our study reveals that the navigation seems to play a limited role on the enrichment of the water columns by dissolved metals and phosphorus, as well as on the oxygenation of surface waters. Conversely, the cycling of the phytoplankton over the year appears to partly control the physico-chemical and chemical evolutions of the overlying waters.

This study aimed to understand the impact of municipal basic sanitation policies and plans on the rate of access to drinking water and sewage services. For this, data were collected from the 853 municipalities of Minas Gerais regarding the provision of sanitation, as well as socioeconomic, quality of life and demographic indicators, treated with the t-test techniques for differences between means and Propensity Score Matching. The results revealed the need for greater sanitation planning in the state since a significant portion of municipalities do not have formal planning instruments for the sector.

Introducing superconductivity in topological materials can lead to innovative electronic phases and device functionalities. Here, we present a unique strategy for quantum engineering of superconducting junctions in moiré materials through direct, on-chip, and fully encapsulated 2D crystal growth. We achieve robust and designable superconductivity in Pd-metalized twisted bilayer molybdenum ditelluride (MoTe) and observe anomalous superconducting effects in high-quality junctions across ~20 moiré cells.

Background: Cold-water immersion (CWI) has gained popularity as a health and wellbeing intervention among the general population.
Objective: This systematic review and meta-analysis aimed to evaluate the psychological, cognitive, and physiological effects of CWI in healthy adults.
Methods: Electronic databases were searched for randomized trials involving healthy adults aged ≥ 18 years undergoing acute or long-term CWI exposure via cold shower, ice bath, or plunge with water temperature ≤15°C for at least 30 seconds.

The proliferation of cyanobacteria has become a significant water management challenge due to the increasing eutrophication of water supply reservoirs. Cyanobacterial blooms thrive on elevated nutrient concentrations and form extensive green mats, disrupting the local ecosystem. Furthermore, many cyanobacterial species can produce toxins that are lethal to vertebrates called cyanotoxins.

Background: During the COVID-19 outbreak in December 2022 in China, some laboratory workers in SARS-CoV-2 nucleic acid testing (NAT) laboratories remained uninfected.
Objectives: To evaluate if the incidence of SARS-CoV-2 infection was reduced in laboratory workers who performed SARS-CoV-2 NAT, and whether this reduction resulted from the healthy worker effect.
Methods: This retrospective cohort study included 423 laboratory workers from 14 SARS-CoV-2 NAT laboratories in Xiamen, China.
