Fine particles known as combustible dusts can cause explosions when they are suspended in the air under certain conditions. A dust explosion could result in severe fatalities, injuries, and structural devastation. The risk of such events can be reduced by knowing the flammability parameters and the physico-chemical analysis for combustible dusts, in order to take additional protective measures generated by the occurrence of these types of explosive mixtures. The purpose of this research was to identify the flammab...

Certain studies have determined specific conifers, which can be found in urban and industrial areas can be used to monitor the degree of air pollution being used for passive biomonitoring processes. The needles and bark of conifers taken from the industrial and urban areas of the Jiu Valley, mercury, chromium) and arsenic, after acid mineralization of the samples of pine bark (Pinus sp.), spruce (Picea Abies) and thuja (Thuja Occidentalis) and those taken from these conifers in the urban area and in the vicinity o...
