Exposure to fine particulate matter (PM2.5) has been linked visual impairment. Nevertheless, evidence associating PM2.5 constituents with impairment in schoolchildren is sparse. To explore the effects of long-term exposure and its on We conducted a large cross-sectional population-based study recruit 59,054 from four cities Guangdong province, China, used ChinaHighAirPollutants (CHAP) dataset estimate 3-year average concentrations (black carbon (BC), organic (OM), nitrate (NO3-), sulfate (SO42-) ammonium (NH4+)) based individuals' home addresses. Visual acuity was measured standardized logarithmic chart, defined as below 4.9 (Snellen 5/6 equivalent) at least one eye. utilized generalized linear mixed models weighted quantile sum regression assess association between The observed associations typically displayed nonlinear pattern. Compared lowest quartile constituents, fourth associated higher odds (e.g., adjusted ratio (OR) 1.23 (95% CI: 1.13, 1.33) for PM2.5, 1.53 1.40, 1.67) OM, 1.35 1.27, 1.44) BC), respectively. Similarly, joint (OR = 1.17, 95% 1.22), while BC OM contributed more associations. Long-term significantly rates schoolchildren, combustion-related potentially driving

Environmental Risk Factors for Parkinson's Disease: A Critical Review and Policy Implications

Abstract The age‐standardized prevalence of Parkinson's disease (PD) has increased substantially over the years and is expected to increase further. This emphasizes need identify modifiable risk factors PD, which could form a logical entry point for prevention PD. World Health Organization (WHO) recommended reducing exposure specific environmental that have been reported be associated with in particular pesticides, trichloroethylene (TCE), air pollution. In this review we critically evaluate epidemiological biological evidence on associations these PD whether putative are causal. We conclude when considered isolation, it difficult determine causal, large part because decades‐long lag between relevant exposures incidence manifest However, tandem from complementary research lines (such as animal models), increasingly likely reflect harmful causal effects. Fundamentally, whilst highlight some gaps require further attention, believe current base sufficiently strong enough support our call stronger policy action. © 2024 Author(s).

Fine particulate matter, known as PM2.5, is recognized a risk factor for dementia. However, the specific linkage between PM2.5 constituents and dementia not well understood. We conducted cohort of 217,336 participants UK Biobank to explore association long-term exposure with all-cause dementia, Alzheimer's disease (AD), vascular estimated based on residential addresses by an evaluation model used time-varying Cox models Quantile g-computation assess effects individual their mixtures. Genetic susceptibility was assessed using polygenic score, its multiplicative additive interactions were analyzed. Our results showed that black carbon (BC), ammonium (NH4+), organic matter (OM), sulfate (SO42-) positively associated while BC OM linked AD, being most influential. The combined effect genetic stronger than effect. This study offers new insights into especially those from fuel combustion automobile exhaust, highlights need effective prevention strategies.

Air Quality Monitoring Using Low-Cost Sensors in Urban Areas of Jodhpur, Rajasthan

International Journal of Environmental Research and Public Health, Год журнала: 2024, Номер 21(5), С. 623 - 623

Опубликована: Май 14, 2024

Air pollution poses a significant health hazard in urban areas across the globe, with India being one of most affected countries. This paper presents environmental monitoring study conducted Jodhpur, Rajasthan, India, to assess air quality diverse environments. The involved continuous indoor and outdoor monitoring, focusing on particulate matter (PM2.5) levels, bioaerosols, associated meteorological parameters. Laser sensor-based low-cost monitors were utilized monitor Anderson 6-stage Cascade Impactor & Petri Dish methods for bioaerosol monitoring. revealed that PM2.5 levels consistently high throughout year, highlighting severity region. Notably, often higher than challenging common notion staying indoors during peak pollution. explored spatial temporal diversity various land-use patterns within city, emphasizing need tailored interventions different areas. Additionally, assessments unveiled presence pathogenic organisms environments, posing risks residents. These findings underscore importance addressing bioaerosols management strategies. Despite study’s valuable insights, limitations, such as using sensors long-term data collection, are acknowledged. Nevertheless, this research contributes better understanding dynamics public awareness mitigating adverse effects In conclusion, underscores urgent effective strategies provide insights policymakers researchers striving address rapidly urbanizing regions.
