“…Different PAH sources may provide specific patterns or signatures, which can be used to identify the sources (Liu et al, 2012;Liu et al, 2005). According to Yunker et al (1999), PAHs can be grouped in two subsets on the basis of their stability.…”

“…PAHs are produced mainly from the incomplete combustion of coal, petroleum and biomass materials and are used as a proxy to trace the impact of anthropogenic activities (Liu et al, 2012;Liu et al, 2005). Curitiba is one of the most important cities in Brazil and has undergone significant social and economic development since its founding.…”

“…Curitiba is one of the most important cities in Brazil and has undergone significant social and economic development since its founding. Previous studies have reported that the concentrations of PAHs in the environment are strongly influenced by the local human population (Zhang et al, 2013;Li et al, 2008), industrialization activities (Kumar et al, 2008), the number of vehicles (Liu et al, 2005), the length of highways and energy consumption (Liu et al, 2012). Hence, the relationship from the 1850s to the present between PAHs concentrations and local historic socioeconomic data was evaluated to examine the influence of economic development on the local environment.…”

“…PAH analysis in sediment/SPM largely followed the procedures described previously (Liu et al, 2005). In brief, sediment/ SPM samples were homogenized and freeze-dried, and the dried sediments/SPM were spiked with PAH surrogates (acenaphthene-d 10 , phenanthrene-d 10 , chrysene-d 12 and perylene-d 12 ) and soxhlet-extracted with dichloromethane for 48 h. Activated copper granules were added to remove elemental sulphur.…”

“…Recent studies of sediment cores and surficial bed sediments in the Pearl River Delta have indicated that the inputs of polycyclic aromatic hydrocarbons (PAHs) (Liu et al 2005) and heavy metals (HMs) (Gan et al 2010) parallel the increase in industrialization around the Pearl River Delta. Mai et al (2002) and Liu et al (2002) respectively reported that partial areas of the Pearl River have higher sedimentary PAH and/or HMs concentrations, forming "higher risk area".…”

The accelerated industrialization and urbanization in the last three decades around the Pearl River Delta within Guangdong Province in China have led to serious concerns about the impacts on the aquatic environment. In the present study, the genotoxicity of the sediments collected from the Pearl River was evaluated by micronucleus (MN) assay with Vicia faba root tip cells, and the 16 EPA priority polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs, including Cr, Cu, As, Se, Cd, Hg, and Pb) in the sediments were determined respectively by GC-MS, inductively coupled plasma mass spectrometry, and inductively coupled plasma atomic emission spectrometry. The results showed that there were significant increases of MN frequencies observed in the sediment-exposed groups, compared with the negative group (P<0.05, P<0.01), indicating that the sediments clearly had genotoxicity to the V. faba root cells. The total concentrations of the priority PAHs (250-13,656 ng g −1 , dry weight) and HMs (As, 22,770-36,639 μg kg − 1 ; Cr, 39,333-133,343 μg kg −1 ; Cu, 36,145-159,270 μg kg −1 ; Pb, 5 1 , 2 1 0 -1 6 6 , 6 4 2 μ g kg − 1 ; C d , 4 7 5 . 4 -1,818.9 μg kg −1 ; Hg, 59.9-460.8 μg kg −1 ; and Se, 331.7-1,250.4 μg kg −1 , dry weight) were close to those obtained from other urbanized and industrialized areas, which have been considered moderately polluted. There was a clear positive correlation between MN potency and the molar concentrations of Hg and Pb in the sediments (Hg, r=0.94; Pb, r=0.91), suggesting that Hg and Pb were the most important factors that posed the sediments higher genotoxicity to V. faba root cells. Our results suggested that both biological and chemical approaches are necessary to be included in a battery of tests to assess the eco-environmental risks of sediments.
