The main purpose of this research is the calculation of implicit prices of the environmental level of air quality in the city of Moscow on the basis of housing property prices. The database used contains records of approximately 20 thousand apartments and has been provided by a leading real estate agency operating in Russia. The explanatory variables include physical characteristics of the hous...

Air pollution is accountable for various long-term and short-term respiratory diseases even deaths. normally associated with a decreasing life expectancy. Governments have been implementing strategies to improve air quality. However, natural events always played an important role in the concentration of pollutants. In Australia, lockdown period followed Black Summer 2019–2020 coincided season p...

Photocatalytic reduction of carbon dioxide to formaldehyde was investigated on four semiconductor photocatalysts (FeS, FeS/FeS2, NiO and TiO2). The reaction was carried out in continues flow of CO2 gas bubbled into the reactor. Semiconductor photocatalysts were characterized by X-Ray diffraction (XRD) and Diffuse Reflectance Spectroscopic (DRS) methods. Sulfide ion was used as hole scavenger. T...

the study was aimed to investigate the change of some fatty acids to ambient air pollution in four legumes species Pisum sativum L. and (Vicia faba L.m and during summer season were Glycine max and Vigna sinensis grown in five sites mostly affected by high traffic intensity and or industrial activities in Riyadh city capital of Saudi Arabia. The results showed increasing of air pollution (O3, N...

Extended Abstract Introduction: Nowadays, due to land use change and destruction of natural resources induced by human activities, attention to desertification has immensely become widespread. One of the most important species for biological rehabilitation of desert areas on a large scale is the hawthorn plant. Hawthorn is a plant belonging to the family Amaranthaceae, the two species of which...

Background and aimsThe catalytic ozonation is an efficient process for the degradation of volatile organic compounds from contaminated air stream. This study was aimed at investigating the efficacy of catalytic ozonation process in removal of xylene from the polluted air stream andthe influence of retention time (gas flow rate), inlet ozone dose and relative humidity on this performanceMethodst...

Bronchoalveolar lavage (BAL) which has not previously been used in investigating the effect of sulphur dioxide (SO2) on the human lung was performed on 12 subjects before and after controlled chamber exposure with SO2 for 20 minutes. BAL fluid 24 hours after exposure with 10 mg S02/m3 (4 ppm, 10 subjects) showed increased alveolar macrophage activity as judged by an increase in lysozyme positiv...

BACKGROUND High levels of asthma prevalence and severity of respiratory symptoms have been found in the Caribbean but little is known about the impact of air pollution in these regions. This study aimed to describe air pollution and measure the associations with child lung function in Guadeloupe (French West Indies). METHODS Data from 30 randomly chosen elementary schools (8-13 years old) wer...
