Ⅰ. INTRODUCTION World interest in the long-range transport of dust from dry areas of China to the Pacific and Arctic oceans as well as the possible importance of surface dust as a factor in air quality of North China justifies the investigation of the chemical composition of soil dust in Ch...
The influence of dust condensation on the chemical composition of the AGB star circumstellar envelopeA thermal decomposition furnace in which waste tires having original shape, not broken up, can be laid horizontally and be thermally decomposed. The furnace is constructed by providing a feeder above...
raw materials can be calculated based in two ways which are in principle equivalent: Either based on the amount and chemical composition of the products (clinker plus dust leaving the kiln system, output methods B1 and B2), or based on the amount and composition of the raw materials [...]...
An intensive sampling of aerosol particles from ground level and 100 m was conducted during a strong pollution episode during the winter in Xi'an, China. Concentrations of water-soluble inorganic ions, carbonaceous compounds, and trace elements were determined to compare the composition of particulate...
The traditional viewpoint is thatdust is inherently insoluble but reactive toward trace acidic gases,a process herein referred to as chemical aging. These reactions arethought to affect the oxidizing capacity of the atmosphere while effectivelytransforming the chemical composition of dust by increasing ...
Quantity and chemical (mineral phase) composition of EAF dust depend on composition of scrap and other materials; oxygen injection intensity; process temperature in different periods of melting; off-gasses, etc. Thus, composition of EAF dust can widely vary even from one day to another [1]. Ma...
adusturb dusturb[translate] aSince the chemical composition of AA2024-T3 contains mainly Al and 1.5% Mg, the formation of the conversion coating should be ascribed to the interaction between PA andthese two cations. 因为AA2024-T3的化学成分包含主要Al和1.5%毫克,应该把归咎转化涂层的形成到PA and...
Chemical composition of street sediments in Beijing comprises the information of different sources of atmospheric particles.#This study is only a small contribution to the understanding of substance fluxes related to Beijing's dust. More effort is required to assess Beijing's dust fluxes, since the ...
