“…Owing to extensive economic and industrial development in Nigeria, the concentration of ∑PAHs in Calabar River was higher than [48] that in Qinhuai River [35]. The average content (27,074.1 ng/g) of ∑PAHs in the sediment of Haihe River is about ten times that of Qinhuai River (2,713.8 ng/g); this result could be attributed to the fact that Tianjin was an old and established industrial city with the largest port in north China [37], along with rapid development of the petrochemical industry, the iron and steel industry, and other heavy industries and rapid urbanization [36]. In addition to Luan River as a water source with an average of 115.3 ng/g, ∑PAHs levels of other rivers were relatively high, which were closely related to the economic development and industrialization.…”

In order to investigate the residual characteristics, sources, and ecological risk of PAHs in sediment from urban rivers, the sediments of 15 typical sites from Qinhuai River and Xuanwu Lake, which are typical urban rivers and lake, were collected from October 2015 to July 2016; the sources of PAHs in sediment were also identified by several methods. Results showed that ∑PAHs concentration in sediment ranged from 796.2 ng/g to 10,470 ng/g with an average of 2,713.8 ng/g. High molecular weight PAHs with 4-5 rings were most prominent in the sediment during all four seasons. Source characterization studies based on the analysis of diagnostic ratio (triangular plot method), cluster analysis, and positive factor matrix analysis suggested that the PAHs of Qinhuai River Basin were mainly from pyrogenic origin (biomass and coal combustion and vehicular emission), and the petroleum source also cannot be ignored (specially in summer). Most individual PAHs occasionally affect the aquatic organisms. The highest benzo[a]pyreneequivalent doses (BaP eq dose) appear at the sites of sewage discharge and heavy traffic. So, the PAHs pollution sources of urban water body have obvious seasonal-dependent and human activities-dependent characteristics.

“…Distribution and concentration of PAHs in the environment including air, river water, lakes, sediments and vegetation have been extensively studied (e.g., Patrolecco et al, 2010;Navarro-Ortega et al, 2010;Kafizadeh et al, 2011;Liu et al, 2012;Yan et al, 2012;Slezakova et al, 2013;Hussain et al, 2014;Wu et al, 2014;Hussain et al, , 2015aCheruiyot et al, 2015). Atmospheric deposition of PAHs has not attained much focus compared to other environmental matrices.…”

Bulk atmospheric deposition of Polycyclic Aromatic Hydrocarbons (PAHs) in Guwahati city of the Brahmaputra Valley have been characterised for a period of one year. The ∑PAHs (USEPA's priority 16) and benzo(s)pyrene (BaP) concentrations in the collected bulk deposit ranged between 2.2 and 1035 ng mL -1 , and BDL and 5.6 ng mL -1 respectively. Greater deposition of PAHs was observed during the dry season and the deposition of low molecular weight PAHs (LMWPAHs) were particularly high. The study revealed explicit effect of the prevailing meteorology on the bulk atmospheric deposition characteristics of PAHs. Greater number of inversion days and lowering of inversion height during the dry season were found to enhance deposition of PAHs. Diagnostic ratios indicated pyrogenic origin of the PAHs derived from combustion of diesel, coal and wood combustion. The deposition of LMWPAHs was greatly influenced by temperature. The diurnal variation of relative humidity, and wind pattern were found to affect deposition of PAHs.

“…It is, therefore, pertinent to undertake regular assessment of susceptible water bodies in terms of the level of PAHs considering the potential risk associated with aquatic ecosystem and public health. Cao et al (2010) and Liu et al (2012) identified and studied the distribution and ecological risk of PAHs in Luan and Tuhai-Majia River respectively. PAHs contaminations in river sediment have been studied in some of Indian River such as Gomti (Tripathi et al, 2009) and Yamuna River (Agarwal et al, 2006).…”
