Air pollution in Iran: The current status and potential solutions

Environmental Monitoring and Assessment, Journal Year: 2023, Volume and Issue: 195(6)

Published: May 26, 2023

Air pollution has been integrated into global challenges over the last few years due to its negative impact on health of human beings, increasing socio-economic risks, and contribution climate change. This study attempts evaluate current status Iran's air with regard sources emissions, control policies, consequences that have resulted through available data from monitoring stations reported in literature, official documents, previously published papers. Many large cities Iran surpass permissible concentration pollutants, particularly particulate matter, sulfur dioxide, black carbon, ozone. Although regulations policies are place enormous efforts being made address issues country, implementation enforcement not as effective they could be. The significant may be regarded inefficiency regulation supervision systems, lack quality systems technology, industrial rather than Tehran, continual feedback investigations efficiency regulation. Providing such an up-to-date report can bring opportunities for international collaboration, which is essential addressing worldwide. We suggest a way forward more focused conducting systematic reviews using scientometric methods show accurate picture trend association Iran, implementing approach both change issues, collaborating counterparts share knowledge, tools, techniques.

Peculiar weather patterns effects on air pollution and COVID-19 spread in Tokyo metropolis

Environmental Research, Journal Year: 2023, Volume and Issue: 228, P. 115907 - 115907

Published: April 18, 2023

As a pandemic hotspot in Japan, between March 1, 2020–October 2022, Tokyo metropolis experienced seven COVID-19 waves. Motivated by the high rate of incidence and mortality during seventh wave, environmental/health challenges we conducted time-series analysis to investigate long-term interaction air quality climate variability with viral Tokyo. Through daily time series geospatial observational pollution/climate data, death cases, this study compared environmental conditions multiwaves. In spite five State Emergency (SOEs) restrictions associated pandemic, (2020–2022) period recorded low improvements relative (2015–2019) average annual values, namely: Aerosol Optical Depth increased 9.13% 2020 year, declined 6.64% 2021, 12.03% 2022; particulate matter PM2.5 PM10 decreased 2020, 2022 years 10.22%, 62.26%, 0.39%, respectively 4.42%, 3.95%, 5.76%. For (2021–2022) ratio PM2.5/PM10 was (0.319 ± 0.1640), showing higher contribution aerosol loading traffic-related coarse particles comparison fine particles. The highest rates cases wave (1 July 2022–1 October 2022) may be attributed accumulation near ground levels pollutants pathogens due to: 1) peculiar persistent atmospheric anticyclonic circulation strong positive anomalies geopotential height at 500 hPa; 2) lower Planetary Boundary Layer (PBL) heights; 3) maximum temperature land surface prolonged heat waves (HWs) summer 4) no imposed restrictions. Such findings can guide public decision-makers design proper strategies curb pandemics under stable weather HWs large metropolitan areas.

Prediction models of bioaerosols inside office buildings: A field study investigation

Building Services Engineering Research and Technology, Journal Year: 2023, Volume and Issue: 44(5), P. 577 - 600

Published: July 19, 2023

Bioaerosols formed by microorganisms in the air directly affect people’s health. The quality an office building Shenzhen, China, is investigated and pollutant levels measured on 36 occasions; six times for each of indoor spaces. A relationship between bioaerosols environmental factors was determined using both linear regression analysis Poisson analysis. Our results indicate that a poor predictor concentration based single indicator. In contrast, can better predict bioaerosols, PM 10 may be indicator with greatest impact bioaerosols. As result, simple, fast, low-cost online monitoring method developed reported. paper provides first-hand basic data to bioaerosol helps formulate appropriate guidelines. proposed offers more practical values compared existing studies as our prediction model facilitates estimation at low cost. Additionally, due current maturity cost sensors, suitable large-scale deployment most buildings. Practical application Based measurement from real building, investigation explores indicators through combination probability actual measurement. We establish novel microbial model. work presents effective, low-cost, estimating discusses possibility equipment inside buildings which then support real-time provide healthy environments personnel.

The long-distance spreading and transport of airborne particulate matter (PM) biogenic or chemical compounds, which are thought to be possible carriers SARS-CoV-2 virions, can have a negative impact on the incidence severity COVID-19 viral disease. Considering total Aerosol Optical Depth at 550 nm (AOD) as an atmospheric aerosol loading variable, inhalable fine PM with diameter ≤2.5 µm (PM2.5) coarse ≤10 (PM10) during 26 February 2020–31 March 2022, COVID-19’s five waves in Romania, current study investigates outdoor pandemic Bucharest city. Through descriptive statistics analysis applied average daily time series situ satellite data PM2.5, PM10, climate parameters, this found decreased trends PM2.5 PM10 concentrations 24.58% 18.9%, respectively compared pre-pandemic period (2015–2019). Exposure high levels particles was positively correlated mortality. derived PM2.5/PM10 ratios entire relatively low (<0.44), indicating dominance traffic-related particles’ fraction. Significant reductions averaged AOD over were recorded first third their associated lockdowns (~28.2% ~16.4%, respectively) (2015–2019) levels. findings research important for decision-makers implementing safety controls health measures infections.

This paper uses hierarchical regression analysis, a statistically robust method, to explore the correlations between two meteorological parameters and three particulate matter concentrations. The dataset is provided by six sensors located in cities from countries, measurements were taken simultaneously for months at each minute. Analyses calculations performed with Statistical Package Social Sciences (SPSS). results underscore that complexity of air pollution dynamics affected location even when same type used, emphasize one-size-fits-all approach cannot effectively address pollution. findings are helpful perspectives: education, show how handle communicate solution local communities’ issues about pollution; research, understand easy university can generate analyze open-source data; policymakers, design targeted interventions addressing country’s challenges.

Abstract Background An increasing number of systematic reviews (SRs) in the environmental field have been published recent years as a result global concern about health impacts air pollution and temperature. However, no study has assessed compared methodological reporting quality SRs on effects pollutants extreme temperatures. This aims to assess compare ambient Methods PubMed, Embase, Cumulative Index Nursing Allied Health Literature (CINAHL), Cochrane Library, Web Science, Epistemonikos databases were searched. Two researchers screened literature extracted information independently. The was through A Measurement Tool Assess Systematic Reviews 2 (AMSTAR 2). Preferred Reporting Items Meta-Analyses (PRISMA). Results We identified 405 (286 for pollution, 108 temperature, 11 synergistic effects). included suboptimal, with major deficiencies protocol registration. better than that especially terms satisfactory explanations any heterogeneity (69.6% v. 45.4%). however, adherence assessment results risk bias all (53.5% 34.3%) inadequate. Conclusions Methodological effect higher those registration remain an issue both In addition, developing risk-of-bias tool applicable temperature may improve SRs.
