“…This might reflect the more complex PAHs input sources to these two drainage canals (Mai et al 2003). PAHs sources in surface soil and dustfall has been identified and apportioned (Zuo et al 2007;Wu et al 2005). For soil samples in the urbansuburban zone, 37% PAHs was from a combined source of coal and petroleum, 26% was from a combined source of coking and biomass, and 23% was from incineration (Zuo et al 2007).…”

Polycyclic aromatic hydrocarbons (PAHs) partitioning among dissolved phase, suspended particulate matter, pore water, and sediment was studied in one moderately contaminated river (Yongding New River) and two highly contaminated drainage canals (South Drainage Canal and North Drainage Canal) of Tianjin, China. PAHs concentrations in sediment (ranged from 0.2 to 195 μg/g) showed positive relations with both total organic carbon contents (ranged from 0.7% to 31.1%, dw) and black carbon contents (ranged from 0.1% to 2.1%, dw) in the sediments. Moreover, most of the measured organic carbon normalized partition coefficients of PAHs in the three streams were 0.76 to 1.54 log units higher than the predicted values. These indicated that strong and nonlinear sorption

“…The gross output of TBNA's industries reached 196 billion Yuan (about US $28.6 billion) in 2006, which was about 19 times of that in 1993. Reports have shown that PAHs are present in various environmental media in TBNA, and the highest concentration of PAHs in soil samples from TBNA exceeded 5,000 ng g −1 (Duan et al 2005;Shi et al 2005;Wu et al 2005); however, the industrial influence and regional difference in this area are unclear. There are three districts in TBNA from north to south: Hangu, Tanggu, and Dagang.…”

“…Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds with two or more fused aromatic rings and are widespread throughout environmental media (Edwards 1983;Mielke et al 2001;Wu et al 2005). Because of their toxic, mutagenic, and carcinogenic characteristics, 16 PAHs have been listed as priority pollutants by the US Environmental Protection Agency (USEPA) and studied by scientists all over the world (Kipopoulou et al 1999;Nadal et al 2004;Wang et al 2007).…”

The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were determined by gas chromatography equipped with a mass spectrometry detector in 105 topsoil samples from an industrial area around Bohai Bay, Tianjin in the North of China. Results demonstrated that concentrations of PAHs in 104 soil samples from this area ranged from 68.7 to 5,590 ng g −1 dry weight with a mean of 16PAHs 814 ± 813 ng g −1 , which suggests that there exists mid to high levels of PAH contamination. The concentration of 16PAHs in one soil sample from Tianjin Port was exceptionally high (48,700 ng g −1 ). Ninetythree of the 105 soil samples were considered to be contaminated with PAHs (>200 ng g −1 ), and 25 were heavily polluted (>1,000 ng g −1 ). The sites with high PAHs concentration are mainly distrib- uted around chemical industry parks and near highways. Two low molecular weight PAHs, naphthalene and phenanthrene, were the dominant components in the soil samples, which accounted for 22.1% and 10.7% of the 16PAHs concentration, respectively. According to the observed molecular indices, house heating in winter, straw stalk combustion in open areas after harvest, and petroleum input were common sources of PAHs in this area, while factory discharge and vehicle exhaust were the major sources around chemical industrial parks and near highways. Biological processes were probably another main source of low molecular weight PAHs.

“…Technical improvements in production facilities and/or monitoring equipment, as well as advances in environmental protection are the reasons why this simple method is rarely used in air quality monitoring programmes. It has, however, been employed recently in ambient air pollution monitoring not only in developing countries (1)(2)(3) but also in Australia (4). The same method proved its suitability for indoor dust measurements (5).…”

Dustfall measurements in Primorsko-goranska county started in 1975 in the Bakar Bay (Site 2 -Bakar and Site 3 -Kraljevica). The measurements were extended to the city of Rijeka (Site 1 -Rijeka) in 1982, to the nearby islands (Site 4 -Krk and Site 5 -Cres) in 1986, and inland to Gorski Kotar (Site 6 -Delnice and Site 7 -Lividraga) in 1995. This article brings the results of dustfall measurements from 1975 to 2008. Dustfall was low in the city, the nearby islands, and Gorski Kotar. Recommended and limit values were occasionally exceeded in the Bakar Bay due to emissions from the coke plant and harbour at Site 2 (1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997) and from the shipyard at Site 3. Lead content in the dustfall was below the national limits, save for two occasions at Site 2. Deposition of sulphur and nitrogen at the inland sites were below the respective critical load values.
