The Mg/SO4 and Ca/SO4 ratios indicate that magnesium and calcium arising from the ocean experience little enrichment. However, Cu/SO4 ratios are consistent with an enrichment of copper of 104. 展开 关键词: Aerosols Air Pollution Air Sampling Chemical Composition Particulate Sampling Tasmania Aluminum...
INTRODUCTION The chemical composition of the atmospheric aerosol is one of the main factors that determine the particles' effects on human health and atmospheric visibility. (1-3) Particulate matter (PM) is the air pollutant of greatest concern in Xi'an, the largest city in northwestern China (...
The relationship between composition and flash point is examined by using two prediction methods. The first method is based on the notion of a critical value of fuel-air mass ratio at the flammability limit. The second method is based on Le Chatelier's rule for flammability limits. Both ...
A research team led by Prof. Yele Sun from the Institute of Atmospheric Physics of the Chinese Academy of Sciences analyzed six-year aerosol particle composition measurements to investigate responses ofair qualityto the changes in anthropogenic emissions during the COVID-19 outbreak in Beijing, China...
The ratio of ratios analysis indicated that sulfate and potassium are the most regional species considered and that EC and some metal species have the strongest urban (especially New York City) sources. 展开 关键词: Experimental/ aerosols air pollution atmospheric chemistry atmospheric composition ...
The composition of the crystal and bulk must be the same. 晶体生长所用的大块材料的对映体过量。值0.0表示外消旋体。值为1.0表示该化合物是纯对映体。对映体过量的定义见IUPAC建议(Moss等人,1996)。晶体和块体的组成必须相同。 Reference: Moss G. P. et al. (1996). Basic Terminology of ...

This study provided detailed composition data and comprehensive analysis of PM2.5 during the serious haze pollution period and their potential impact on human health in Xinxiang. 展开 关键词: PM2.5 Haze Air trajectory Health risk Xinxiang DOI: 10.1007/s10653-016-9874-5 被引量: 11 ...
The process is very compact, owing to very rapid throughput and near-stoichiometric air requirements. It is entirely enclosed. The Neutrail SSP process comprises three main steps; drying, oxidation and gas cleaning. The oxidation step consists of three distinct sections. It is designed to ...
