Abstract. Characterizing the chemical composition of ambient particulate matter (PM) provides valuable information on concentration secondary species and toxic metals assists in validation abatement techniques. The components PM can be measured by sampling filters analyzing them laboratory or using real-time measurements species. It is important for accuracy monitoring networks that from offlin...

Abstract. Seasonal variability of non-refractory PM1 (NR-PM1) was studied at a rural background site (National Atmospheric Observatory Košetice – NAOK) in the Czech Republic to investigate effect regional and long-range atmospheric transport central Europe. NR-PM1 measurements were performed by compact time-of-flight aerosol mass spectrometry (C-ToF-AMS), chemically speciated size distributions...

In the present study, 45 rainwater samples were collected from February to December 2012 on event basis in East Bokaro coal mining environment. Physico-chemical and major ionic compositions of rainwater samples as well as water soluble major ion composition were analyzed to employ principle component analysis for source identification. The average pH value was recorded 6.1 and varied from 5.1 t...

Groundwater is an important source of drinking water, particularly in arid regions. In this study, a total 66 groundwater samples were collected from the phreatic aquifer Shizuishan area, traditional irrigation region Ningxia. The results showed that TDS values above water standards for nearly 50% samples. ions followed order Na+ > Ca2+ Mg2+ K+ and SO42− Cl− HCO3− groundwater. There four dom...

Air pollution is becoming increasingly serious along with social and economic development in the southwest of China. The distribution characteristics particle matter (PM) were studied Chengdu from 2016 to 2017, changes PM bearing water-soluble ions heavy metals secondary analyzed during haze episode. results showed that at different levels, more likely be enriched fine particles may used as a t...
