Special Issue Information

Epidemiological studies have shown that air quality is one of the most important environmental concerns for residents and city authorities. Most of the emissions occur in the lower atmosphere, where the increase in contamination is to be considered significantly greater. Air quality monitoring is influenced by the intrinsic heterogeneity of the urban landscape and by the overlapping of multiple polluting sources. The pollutants released into the atmosphere tend to be dispersed by the mechanical turbulence phenomena present in the air. Their dispersion depends on a combination of variables such as wind speed, air stratification, the topography of the emission zone, and the very temperature of the polluting hot gases. Furthermore, regardless of the regional or global scale of pollution, the impact of anthropogenic emissions on the urban atmosphere has become dramatically more pronounced.

The modeling methodology helped identify air pollution patterns and pathways that provide necessary spatial details and maximum concentrations of pollutants especially at greater distances from monitoring stations.

Anthropized areas are characterized by numerous pollutants emitted by anthropic sources both in the form of solid and gaseous particulates. The main sources of pollution can be mainly identified in vehicular traffic, domestic heating,  industrial realities, mining activities, and the possible presence of harbor.

The assessment of air pollution can also be carried out using biomonitoring methods, which in recent years have been receiving increasing favour, as it appears to be an easy, inexpensive and accesible appoach for the determination of atmospheric pollutans.

This special issue of the journal "Atmosphere" focuses on the current state of knowledge on the study of atmospheric pollution in anthropized areas, to determine the concentrations of the main pollutants, model their spatial distribution and identify their sources, measuring their concentration through the use of different methods.

New research papers, reviews are welcome to this issue.

In this paper, a combination of simulation and testing is used to quantitatively analyze the influence of a fresh air system of indoor range hood on kitchen air quality. The evaluation criteria of kitchen air quality are established based on the air age and air exchange efficiency. The results show that, when the fresh air system is switched to on from off, the indoor mean air age is reduced to 94.7 s from 468.6 s, and the air exchange efficiency is improved to 82.4% from 16.7%. The air quality is upgraded to fresh from moderate pollution. The presented simulation analysis process can provide a guideline for in-depth study of the kitchen air quality and quantitatively assess the kitchen fresh air system. Full article
