This paper reports the physicochemical properties that describe the adsorption of a series of solutes onto the surfaces of amorphous carbon blacks. Adsorption was studied at concentrations that correspond to low surface coverages and in the presence of volatile solvent diluents. The adsorbates and adsorbents were selected for their relevance as models for environmental agent-particle complexes ...

3. Applicable Pollutants: Particulate Matter (PM), including particulate matter less than or equal to 10 micrometers (μm) in aerodynamic diameter (PM10), particulate matter less than or equal to 2.5 μm in aerodynamic diameter (PM2.5), and hazardous air pollutants (HAPs) that are in particulate form, such as most metals (except mercury is the notable exception, as a significant portion of emissi...

Extremely high fine particulate matter (PM2.5) concentration has become synonymous to Beijing, the capital of China, posing critical challenges to its sustainable development and leading to major public health concerns. In order to formulate mitigation measures and policies, knowledge on PM2.5 variation patterns should be obtained. While previous studies are limited either because of availabili...

conclusions according to the results obtained, the largest numbers of deaths and illnesses were due to the high average pm10 concentration or an increase in the number of days of exposure to this pollutant. background particulate matters have harmful effects on human health and can intensify mortality and disease. objectives the purpose of this study was to evaluate the health impacts of partic...

The Bosphorus (Istanbul Strait) that connects the continents of Europe and Asia is too complex due to geographical conditions and have a continuously increasing maritime traffic. The length of the Bosphorus which connect the Black Sea and the  Marmara Sea is 29.9 km. The number of ships (Tanker, general Cargo and bulk carrier) passing through the Istanbul strait was recorded as 42553 in 2016 an...

Applicable Pollutants: Particulate Matter (PM), including particulate matter less than or equal to 10 micrometers (:m) in aerodynamic diameter (PM10), particulate matter less than or equal to 2.5 :m in aerodynamic diameter (PM2.5), and hazardous air pollutants (HAPs) that are in particulate form, such as most metals (mercury is the notable exception, as a significant portion of emissions are in...

The lecithinase of Clostridium perfringens is an exoenzyme (3). However, lecithinase activity was demonstrated in cytoplasmic extracts obtained from mechanically disrupted vegetative cells of type A C. perfringens (4). This report deals with the intracellular and extracellular lecithinase activities of vegetative cells and spores of type A C. perfringens. Strain BP6K (1), which produces conside...

introduction: air pollution due to particulate matter is a major environmental and health issue in all regions of the world. the aim of this study was to investigate the health impacts of pm10 (particulate matter with an aerodynamic diameter ≤10μm) in khorramabad city, iran in 2014. materials and methods: in this study, pm10 sampling was conducted by a high-volume sampler at flow rate of 1.1-1....
