Following the outbreak of Corona virus pandemic in Italy, the government has taken extraordinary steps to prevent the disease from spreading. This extraordinary occurrence has resulted in a decline in air pollution levels measured in the entire Po Valley, which is traditionally one of Europe's most polluted areas in terms of particulate matter and nitrogen dioxide concentrations. After the lockdown measure, a significant change in the level and the trend of the pollutant time series has occurred, in particular. The results indicate that only for a single NO 2 station located in a heavy traffic zone during the post-intervention period, after adjusting for meteorology and Sunday effect, indicating that no change in air quality during the post intervention period has been observed.
Nitrogen oxide oxides are highly reactive and significant air pollutants resulting from industrial combustion and combustion of fossil fuels. A super-hydrophilic photocatalyst coated on buildings with a super-hydrophilic photocatalyst coating will bring down the NOx content in the air. In addition, the incorporation of TiO 2 in the form of nanoparticles into cementitious materials would improve their mechanical stability. The study investigates and discusses the use of nano titanium dioxide and its effects on the cementitious composites' fresh and hardened characteristics.
The volcanic regions of Naples and Salerno, two Italian cities, are largely populated with Thermo-mineral springs. The objective of this study was to determine the air concentrations of H 2 S, SO 2, 13 CO 2, 13 CO 2, chemic and microclimatic characterization of the thermal springs in Contursi Terme and Agnano, in order to determine their concentrations and potential impacts on cultural heritage and human health.
Biomass burning is strongly connected to regional air pollution, according to regional air pollution. However, the connection was not consistent in various regions due to the intricate interaction with other driving factors, leaving a substantial gap in understanding the mechanisms of air pollution creation. This research sought to define the spatial heterogeneity and corresponding causes of China's biomass burning-air pollution correlation in recent decades. During the study period, biomass burning occurred mainly in Northeast, Central, and South China, although the number of 143. 08 km 2 yr -1 decreased slightly by -1 km 2 yr -1 during the study period. More specifically, the key contributors of the correlations were gross domestic product in Northeast China, air pollution in Central China, and population in South China. The findings of this research were useful in capturing the physical connection between biomass burning and air pollution, which would further improve relevant air pollution management and monitoring.
Using a symbolic information-theory approach, we investigate the subtle temporal structure of environmental data in this research. The six pollutants data collected in Beijing between 2013 and 2016 are used to distinguish nonlinear deterministic and stochastic dynamics, with newly developed multiscale permutation entropy and complexity causality plane methods. To illustrate a system's complexity, we also specify the relative difficulty measure of multivariate series.
Urban air pollution is extremely complex and reveals a great deal of spatial variation within communities. Traditional centralized monitoring captures temporal change as well as long-term trends of air pollution in communities at high resolution, but establishing spatial distribution of air pollution in communities at high resolution would require a large number of air quality monitors distributed throughout the community. By determining pollution levels on urban highway networks in urban areas, mobile monitoring complements static monitoring methods. The study disaggregated the contribution of regional and local sources to local air pollution, which revealed that regional background sources contributed up to 75% of the PM 2. 5 concentrations, while local sources contributed more than half of BC and UFP. According to the report, 15-30 repeated measurements could be sufficient to map the community's general air pollution patterns, although some extreme high pollution zones can be identified with fewer repeats.
Perilous engineered blends break down to the Earth by unique traditional or even phylogenesis procedures, leading to frightening effects on individual health and the natural world. One of the oldest centuries of the non-sustainable power station, as well as the renewed all-around association, is stretched out. In the paper, the effects of air poisonings on human health and their campaign's device are discussed right away. There are no adverse effects of air pollution on residential human health, according to We tested and established a hypothesis.
The production of anthropogenic pollutants such as factories, motor vehicles, and others is largely responsible for outdoor air pollution for anthropogenic sources. Children were more likely to have health problems when exposed to air pollution than adults, relative to adults. In Parit Raja, Batu Pahat, this cross-sectional comparative study was conducted to determine the relationship between industrial air pollution exposure and respiratory diseases among children aged 3 to 12 years old. Those who live less than 5 km from the factory area were chosen as the exposed group, while those who live more than 5 kilometers from the industrial areas were chosen as the comparative group. For the exposed and the comparative group, respiratory health indicators of cough and phlegm were significantly different between the exposed and the comparative group at p = 0. 038 and p = 0. 008, respectively.
The present investigation is intended to determine the air pollutant levels of Ambattur Municipality, Chennai, using AERMOD. The key pollution sources used in this analysis were classified as residential, commercial, aviation, and industrial sources. As source input to determine the pollutant concentration from the study area determined on the Top-Down Approach method, emission characteristics were used. The pollutant dispersion concentrations retrieved from the model were much lower than the measured values for both parameters, according to the study results.
Working in heavy traffic and congested junctions with bad air for long hours has compromised the respiratory performance of Malaysian Traffic Police. A wireless outdoor individual exposure device is crucial to track their exposure, but the system's effectiveness is uncertain. This paper aims to develop a quantitative framework for a qualitative analysis of the wireless outdoor individual exposure indicator system prototype. Future researchers may be able to develop a monitoring platform that is relevant to their requirements using the three-stage approach.
