“…A staggering 80% of the global population is affected by excessive levels of artificial light. Research links light pollution to health issues, including multiple mental disorders ( 77 – 79 ). Outdoor and indoor dim artificial light at night (dLAN), usually around 5-10 lux, plays a key role in light pollution’s impact on neurodegeneration ( 80 , 81 ), often exceeding the minimum light pollution threshold in many countries ( 82 ) ( Figure 3 ).…”

Environmental pollution exposures, including air, soil, water, light, and noise pollution, are critical issues that may implicate adverse mental health outcomes. Extreme weather conditions, such as hurricanes, floods, wildfires, and droughts, may also cause long-term severe concerns. However, the knowledge about possible psychiatric disorders associated with these exposures is currently not well disseminated. In this review, we aim to summarize the current knowledge on the impact of environmental pollution and extreme weather conditions on mental health, focusing on anxiety spectrum disorders, autism spectrum disorders, schizophrenia, and depression. In air pollution studies, increased concentrations of PM2.5, NO2, and SO2 were the most strongly associated with the exacerbation of anxiety, schizophrenia, and depression symptoms. We provide an overview of the suggested underlying pathomechanisms involved. We highlight that the pathogenesis of environmental pollution-related diseases is multifactorial, including increased oxidative stress, systematic inflammation, disruption of the blood-brain barrier, and epigenetic dysregulation. Light pollution and noise pollution were correlated with an increased risk of neurodegenerative disorders, particularly Alzheimer’s disease. Moreover, the impact of soil and water pollution is discussed. Such compounds as crude oil, heavy metals, natural gas, agro-chemicals (pesticides, herbicides, and fertilizers), polycyclic or polynuclear aromatic hydrocarbons (PAH), solvents, lead (Pb), and asbestos were associated with detrimental impact on mental health. Extreme weather conditions were linked to depression and anxiety spectrum disorders, namely PTSD. Several policy recommendations and awareness campaigns should be implemented, advocating for the advancement of high-quality urbanization, the mitigation of environmental pollution, and, consequently, the enhancement of residents’ mental health.

“…This was confirmed by Liao et al (2022) [3] using data extracted from United Kingdom Biobank Cohort participants to associate higher NTL with increased mental, including depressed mood, tiredness/lethargy, and physical health problems such as obesity as well as more air pollution, less green space, higher economic and neighborhood deprivation and higher household poverty. Leveraging this dataset, a further study established a connection between heightened NTL exposure and an elevated risk of substance use disorder and depression, particularly in individuals with increased iron deposition in the hippocampus and basal ganglia [48]. Several studies have also tied NTL emissions with measurements of people’s perceptions of health and safety, at times showing beneficial effects of NTL, such as feelings of safety and self-reported health [82].…”

While numerous studies over the last decade have highlighted the important influence of environmental factors on mental health, globally applicable data on physical surroundings are still limited. Access to such data and the possibility to link them to epidemiological studies is critical to unlocking the relationship of environment, brain and behaviour and promoting positive future mental health outcomes. The Adolescent Brain Cognitive Development (ABCD) Study is the largest ongoing longitudinal and observational study exploring brain development and child health among children from 21 sites across the United States. Here we describe the linking of the ABCD study data with satellite-based “Urban-Satellite” (UrbanSat) variables consisting of 11 satellite-data derived environmental indicators associated with each subject’s residential address at their baseline visit, including land cover and land use, nighttime lights, and population characteristics. We present these UrbanSat variables and provide a review of the current literature that links environmental indicators with mental health, as well as key aspects that must be considered when using satellite data for mental health research. We also highlight and discuss significant links of the satellite data variables to the default mode network clustering coefficient and cognition. This comprehensive dataset provides the foundation for large-scale environmental epidemiology research.

“…Iron (Fe 3+ ) is one of the most important elements affecting the health of human beings, and it can enter the circulation of the human body through water and food sources, which is highly associated with anemia, kidney stones, and digestive discomfort diseases . Therefore, there is a need to develop sensitive Fe 3+ detection instruments for monitoring water sources, such as inductively coupled plasma atomic emission spectrometry (ICP-AES), liquid chromatography (HPLC) and atomic absorption spectrometry (AAS), and fluorescence methods . However, the cumbersome operation of the instrument, prolonged testing periods, expensive equipment, and fixed testing sites limit practical usage .…”

Carbon polymer dots (CPDs) show incredible potential due to their outstanding optical characteristics, simple synthesis using low-cost precursors, and diverse applications. This study aimed to develop chromium-doped CPDs (Cr-CPDs) using an efficient one-step microwave method for fluorescence sensing and optoelectronic devices. The one-pot microwave synthesis used citric acid, urea, C 6 H 9 O 6 Cr, and N,N-dimethylformamide. The resulting Cr-CPDs demonstrated excitation-dependent photostability with a high fluorescence quantum yield of 15.56%, making them promising for fluorescence-based applications. Our experiments showed that the Cr-CPDs' fluorescence could be effectively quenched in the presence of Fe 3+ ions, allowing detection down to 0.52 μM concentration. By combination with PVA, flexible composite films were created for visual ion sensing. Static quenching and IFE dynamics work synergistically to underpin the selective and sensitive fluorescent detection function of Cr-CPDs for Fe 3+ . These Cr-CPDs further served as colorful inks for multifunctional information encoding. Most significantly, incorporating the Cr-CPDs into PVA films and assembling them on lightemitting devices (LEDs) led to efficient blue-and green LEDs. This study opens new possibilities for cost-effective luminescent materials and next-gen electronics.
