“…Fig.3 shows the hourly mean Hgo concentrations at 02:00, 08:00, 14:00 and 20:OO and the overall average concentration during each monitoring campaign at Yangtze Delta regional site. The overall mean Hg" concentrations were 5.4+4.1 ng/m3 in the monitoring campaign, which were higher the concentrations (1.32-1 3 3 ng/m7) in Canada rural sites (CAMNet) (Kellerhals et ul., 2003) and the concentrations (1.63*0.3S ng/m') in summer season at Poland rural site (Zielonka et al, 2005). Contrary to Mt.…”

An investigation of gaseous elemental mercury concentration in atmosphere was conducted at Beijing and Guangzhou urban, Yangtze Delta regional sites and China Global Atmosphere Watch Baseline Observatory (CGAWBO) in Mt. Waliguan of remote continental area of China. High temporal resolved data were obtained using automated mercury analyzer RA-915+. Results showed that the overall hourly mean Hgo concentrations in Mt. Waliguan were 1.7-+1.1 ng/m3 in summer and 0.6+0.08 ng/m' in winter. The concentration in Yangtze Delta regional site was 5.4+4.1 ng/m3, which was much higher than those in Waliguan continental background area and also higher than that found in North America and Europe rural areas. In Beijing urban area the overall hourly mean Hg" concentrations were 8.3+3.6 ng/m3 in winter, 6.5+5.2 ng/m3 in spring, 4.9k3.3 ng/m3 in summer, and 6.7*3.5 ng/m3 in autumn, respectively, and the concentration was 13.5k7.1 ng/m' in Guangzhou site. The mean concentration reached the lowest value at 14:O and the highest at O2:OO or 20:OO in all monitoring campaigns in Beijing and Guangzhou urban areas, which contrasted with the results measured in Yangtze Delta regional site and Mt. Waliguan. The features of concentration and diurnal variation of Hg" in Beijing and Guangzhou implied the importance of local anthropogenic sources in contributing to the high Hg" concentration in urban areas of China. Contrary seasonal variation patterns of Hg" concentration were found between urban and remote sites. In Beijing the highest Hg'concentration was in winter and the lowest in summer, while in Mt. Waliguan the Hgo concentration in summer was higher than that in winter. These indicated that different processes and factors controlled Hg" concentration in urban, regional and remote areas.

“…TPM samples for mercury analyses were collected on 47 mm Tefl on fi lters (0.45 mm pore size) housed in acid cleaned Tefl on fi lter packs at a nominal fl ow rate of 10 l min -1 [29]. After sampling the fi lters were placed into acid-cleaned Petri dishes and stored in a refrigerator.…”

“…After sampling the fi lters with dry deposition were placed into acid-cleaned Petri dishes and stored in the refrigerator. The fi lters with dry deposition were analyzed following the same procedure as TPM fi lters [29,41]. Wet deposition samples were preserved with 1 ml of stabilizing solution (nitric acid and potassium dichromate -5 g K 2 Cr 2 O 7 + 500 ml HNO 3 /1000 ml) and stored in a Tefl on bottle in the refrigerator.…”

Astract:The aim of this work was to identify concentration levels of different chemical forms of mercury (TGM, TPM) in the ambient air in selected areas of the Silesian Region, characterized by low and high mercury emission. Based on the obtained data TGM and TPM concentration levels were determined. The project also focused on determination of dry and wet deposition of mercury compounds. Data concerning TGM and TPM fl ux rates in the ambient air and data on mercury deposition were used to determine a deposition coeffi cient. The coeffi cient was calculated as a share of mercury deposition on the land surface (dry and wet) to the amount of this contaminant transported with loads of air in the form of TGM and TPM in a given measurement station. At both monitoring stations the deposition coeffi cient did not exceed 0.2 %. The idea of calculating the deposition coeffi cient based on the analysis of TGM and TPM fl ux rate is a new solution. The proposed deposition coeffi cient allows to quantify information on a selected contaminant concentration and its potential impact resulting from deposition. Further studies on the deposition coeffi cient may contribute to the development of methods for estimating the impact of contaminants contained in the ambient air on other environmental components based on the analyses of the contaminant fl ux rate.

“…The former East Countries still constitute a source area for airborne mercury. In Southern Poland, for example, the mercury deposition may during winter be more than 10 times higher then in Southern Sweden (Zielonka et al, 2005). Mercury deposition appears to decrease at many of the investigated sites, but at a slower rate than during the 1990-ties.…”
