Environmental legislation is moving towards global standards for ease of application and to impose sanctions and penalties when necessary, without compromising human health and biota. International environmental measures for control and monitoring of atmospheric air only monitor emissions of SOx, NOx, O3, and Pb. In general, most research work in air pollution done using the analysis of elements in rainwater show analysis of trace metals such as Na, Mg, Zn, and Mn. In this work, trace metals in the rainwater at the city of Goiânia, capital of the State of Goiás, were analyzed. Goiânia is a large city set in a predominantly agricultural province located in central Brazil. Presence of trace metals in rainwater was detected, indicating atmospheric air pollution levels higher than occupational limits set by WHO.

Abstract Background High serum bilirubin levels have been shown to be associated with an improved pulmonary function test results. Their potential ability to similarly benefit pulmonary function in an environment of polluted air has not been tested. We retrospectively analyzed data of 15,605 apparently healthy individuals in order to evaluate the effect of serum bilirubin levels on forced expiratory volume in 1 s (FEV1). Methods Individuals attended the Tel-Aviv Medical Center Inflammatory Survey for a routine annual health check between February, 2002 and June, 2009 and were divided into low, medium and high serum bilirubin levels. Their FEV1 results were compared under various levels of air pollution. Air pollution and weather data were obtained from air pollution monitoring stations of the Israeli Ministry of Environmental Protection. Results The elevated serum bilirubin concentrations on FEV1 were evaluated under moderate and high pollution levels FEV1 and were significantly higher in participants with high blood bilirubin levels compared to medium or low levels (p < 0.001 and p = 0.018, respectively). Participants with high levels of bilirubin had preserved FEV1 under exposure to high and medium pollution levels of both Nitrogen Oxide (NOx) and Carbon Monoxide (CO) pollutants (p = 0.003 and p = 0.022, respectively). The multivariate regression analysis revealed that the influence of bilirubin under conditions of air pollution remained significant even after adjustment for FEV1 confounders, but the interaction was not significant. Conclusions Elevated serum bilirubin concentrations are associated with preserved lung function in healthy individuals in Israel exposed to high levels of air pollution.

Abstract Air pollution is a current concern of people and government entities. Therefore, in urban scenarios, its monitoring and subsequent analysis is a remarkable and challenging issue due mainly to the variability of polluting-related factors. For this reason, the present work shows the development of a wireless sensor network that, through machine learning techniques, can be classified into three different types of environments: high pollution levels, medium pollution and no noticeable contamination into the Ibarra City. To achieve this goal, signal smoothing stages, prototype selection, feature analysis and a comparison of classification algorithms are performed. As relevant results, there is a classification performance of 95% with a significant noisy data reduction.

This article summarizes the obtained results of assessing the effectiveness of monitoring of atmospheric air pollution in the city of Sevastopol by stationary and mobile sources and gives recommendations for its improving. Analysis of the existing air monitoring network shows that the monitoring system needs to be modernized due to a number of identified inconsistencies: the number of stationary posts in the city of Sevastopol does not meet the requirements of RD 52.04.186-89 and their number should be increased; the location of stationary posts does not allow obtaining an objective picture of air pollution in all areas of the city; the list of specific impurities subject to control requires clarification and justification based on the available data on the actual intake of pollutants into the city atmosphere; the location of checkpoints on highways does not cover all highways in the city. A list of the largest stationary pollution sources is compiled. Maximum permissible emissions of 243 enterprises are analyzed, including information on 1482 sources of emissions. The main sources of air pollution are revealed and their ranking by gross emissions is performed. An assessment of the data of field observations of atmospheric air pollution in the city of Sevastopol for compliance with the current standards is carried out and a preliminary list of pollutants is formulated to justify the expediency of their control at stationary and route points of the city. The article describes some aspects of a large-scale study aimed at assessing the effectiveness of the air pollution monitoring in the city of Sevastopol. Other stages of research and proposals for modernizing the monitoring system are planned to be published in a series of subsequent articles.

Advantages And Disadvantages

The state of air pollution monitoring in Kyiv city was investigated. There were discussed the relevance of observation system optimization, advantages and disadvantages of the current monitoring network for air pollution in the urban atmosphere. The united complex approach was used for justification of mentioned optimization, which was combined with emission inventories databases, meteorological air pollution potential characteristics, ratified ground-based measurements data of main pollutants, and demographic urban features. The paper discusses main meteorological parameters which drive pollutants’ dispersion. Analysis provide evidence of its huge impact for the pollution regime formation and tendency to the decline of air quality, which must be taken in consideration during optimization for atmospheric air monitoring. The process of optimization for atmospheric air monitoring takes into account the orographic urban features used mainly for the purpose of statistically valid data provision. Therefore, in small microclimatic zones the monitoring sites are located within relief bodies, which are representative for the area. The research estimates results of boundary pollutants’ content caused by middle and high stationary emission sources, defined from the methodology connected with combined IEM diffusive model. Analysis of observations confirms the accuracy of defined structure for urban pollution fields. The combine usage of modeling results and observations allows increasing of atmospheric air quality estimations and helps to optimize the network with minimal amount of necessary representative sites.
