Porphyrin‐based porous organic polymers (Por‐POPs) are attracting increasing attention because of their potential in visible light photocatalysis. The distinctive attributes Por‐POPs have been elucidated by investigating response to specific reactions, such as the aerobic oxidation sulfides. However, most researchers choose porphyrin molecules with relatively short peripheral substituent chains...

Air pollution primarily originates from substances that are directly emitted natural or anthropogenic processes, such as carbon monoxide (CO) gas in vehicle exhaust sulfur dioxide (SO2) released factories. However, a major air problem is particulate matter (PM), which an adverse effect of wildfires and open burning. Application tools for monitoring risk areas using real-time with drones have em...

BACKGROUND The waste transfer stations (WTSs) is one of the most important factors affecting on environment and human health. This research is aimed to evaluate health risk of VOCs among WTS personnel and provide a model for dispersion of VOCs. The Air Pollution Model (TAPM) is able to simulate WTS emissions dispersion over each town. RESULT GC-MS was used to analysis collected gas samples to...

Particulate matter represents a serious hazard to human health, and air quality models contribute the understanding of its dispersion. This study describes particulate with ≤10 μm diameter (PM10) dynamics in an urban–industrial area, through comparison three datasets: modeled (TAPM—The Air Pollution Model), measured concentration (environmental control stations—ECS), leaf deposition values. Res...

Air pollution models that can be used to predict pollution concentrations for periods of up to a year are generally semi-empirical/analytic approaches based on Gaussian plumes or puffs. As input, these models typically use either a simple surface-based meteorological observations file or winds from a diagnostic wind-field model. The latter is basically a sophisticated interpolation model making...

Continuous measurements of the air pollutant concentrations at monitoring stations serve as a reliable basis for air quality regulations. Their availability is however limited only at locations of interest. In most situations, the spatial distribution beyond these locations still remains uncertain as it is highly influenced by other factors such as emission sources, meteorological effects, disp...
