Trends and forecasts of the main atmospheric pollutants (O3, SO2, NO2, CO, PM10, PM2.5, NO and NOx) are estimated by regions in the Mexico City Metropolitan Area (MCMA) with maximum daily data from 2008 to 2018. A non-parametric statistical smoothing cont... see more

The descriptive study related to the evolution of O3, NO, NO2, CO, SO2, CH4, NMHC and PM10 concentrations in downtown Sfax showed, during the period October 1996-June 1997, that the city is significantly influenced by many source... see more

AIM: This paper aims to create a mathematical model for forecasting the morbidity of the population in the Republic of Bulgaria and the Stara Zagora Municipality in particular as a consequence of the atmospheric pollution.SUBJECTS AND METHODS: This model ... see more

Because of their fixed life and wide distribution, plants are the first victims of air pollution. The atmosphere is considered polluted when the increase of the rate of certain components causes harmful effects on the different constituents of the ecosyst... see more

An instrument based on the Multi Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) technique was designed and constructed to measure scattered sunlight in the UV-visible region at different elevation angles. Slant column densities (SCDs) of spe... see more

A method has been developed to detect hazardous conditions of contaminated air in urban areas in real time for an arbitrary number of pollutants. The method is based on restoring the hidden dynamics of the combined risk of instantaneous action on the basi... see more

A mathematical model of joint determining the risk to human health and the identification of hazardous states of the polluted urban atmosphere based on the measurement of current concentrations of pollutants was developed. The structure of the model inclu... see more

This study analyzes the change in the calculated reduced emissions of pollutants by all major categories of road vehicles of European environmental classes from "Euro-0" to "Euro-6". It covers cars, light commercial vehicles, trucks, buses, and category L... see more

Currently, atmospheric pollution is one of the main causes of premature mortality in the world. The problem is especially relevant for economically underdeveloped countries, in particular Ukraine, the economy of which has been developing for a long time i... see more
