Twenty-two street dust samples collected from a small steel city, central China, were analyzed for 16 USEPA priority PAHs to investigate the concentration, spatial distribution relationship with black carbon (BC) and Iron (Fe), and the source apportionment and to assess the health risk of these compounds. The mean contents of PAHs, BC and Fe were 4.43 µg g -1 , 12837.97 mg kg -1 , 70205.70 mg kg -1 , respectively. The highest spot was in the surrounding of the E'zhou Steel Plant and the Steel Rolling Mill of E'zhou. The correlation analysis indicated that there was no obvious relationship between Fe with each other, the PAHs significantly correlated to black carbon (BC), which might be caused by the continuous emission sources of iron and steel production. The results of sources identification suggested that PAHs contaminations in street dust were a mixed source of industrial production and traffic emission combustion. The incremental lifetime and cancer risks (ILCRs) of exposing to PAHs in the street dust of the E'zhou city for the three age groups (namely childhood, adolescence, adulthood) fluctuated with in the range of 10 -6 to 10 -4 , indicating a potential of carcinogenic risk for exposed populations.

“…The levels of carcinogenic potency of each PAH compounds in the surface street dust were calculated and assessed on the basis of its BaP equivalent (BaPequi) concentration using toxic equivalence factors (TEFs) ( [101]), traffic soil of Delhi, India (1009 ng BaPequi /g [58]). Whereas total PAHBaPequi values in street dusts of Jeddah was higher than those found in street dust of Guwahati city (357.7 ng BaPequi /g [14]), Lanzhou, China (300 ng BaPequi /g [44]), street dust of Asansol city, India (661 ng BaPequi /g [8]).…”

Polycyclic aromatic hydrocarbons (PAHs) in street dust pose a serious problem threatening both environment and human health. Street dust were collected from five different land use patterns (traffic areas TRA, urban area URA, residential areas REA, mixed residential commercial areas MCRA and suburban areas SUA) in a Saudi coastal city, Jeddah, and one in rural area (RUA) in Hada Al Sham. This study aimed to investigate the status, profile, sources of PAHs and estimate their human health risk. The results revealed an average concentration of total PAHs of 3320 ng/g in street dust of Jeddah and 223 ng/g in RUA dust. PAHs with high molecular weight represented 83.38% of total PAHs in street dust of Jeddah, while the carcinogenic PAH compounds accounted 57.84%. The highest average concentration of total PAHs in street dust of Jeddah was found in TRA (4980 ng/g) and the lowest in REA (1660 ng/g). PAHs ratios indicated that the principal source of PAHs in street dust of Jeddah is pyrogenic, mainly traffic emission. Benzo(a)anthracene/ chrysene (BaA/CHR) ratio suggests that PAHs in street dusts of Jeddah come mainly from emission of local sources, while PAHs in RUA might be transported from the surrounding urban areas. The estimated Incremental Lifetime Cancer Risk (ILCR) associated with exposure to PAHs in street dusts indicated that both dermal contact and ingestion pathways are major contributed to cancer risk for both children and adults. Based on BaPequivalence concentrations of total PAHs, ILCRIngestion, ILCRdermal and cancer risk values for children and adults exposed to PAHs in street dust of different areas in Jeddah were found between 10−6 and 10−4, indicating potential risk. The sequence of cancer risk was TRA > URA > MCRA > SUA > REA. Only exposure to BaP and DBA compounds had potential risk for both children and adults.

“…In addition to fine sediment, various other pollutants from road run-off can affect stream ecosystems negatively (Brown, 1994;Gilson, Malivia, & Chareneau, 1994;Lamont & Blyth, 1995;Yousef, Wanielista, Harper, & Skene, 1983;Yousef, Wanielista, & Harper, 1985). Depending on the location, rural versus urban, as well as the land use (e.g., agriculture and mining), road run-off may include a range of pollutants such as fertilizers, pesticides, herbicides, solutes, heavy metals, plastics, polycyclic aromatic hydrocarbons, mineral oil hydrocarbons, pharmaceutical contaminants, and soluble salts (Froehner et al, 2012;Göbel, Dierkes, & Coldewey, 2007;Hussain, Rahman, Prakash, & Hoque, 2015;Wang, Zhang, Wu, & Wang, 2017) Many studies investigating road run-off in temperate areas have focused on de-icing salts and heavy metals. The primary de-icing FIGURE 7 Impact of a major transportation corridor on the estuarine ecosystem of the coastal estuary complex Ciénaga Grande de Santa Marta (CGSM), Colombia.…”

Ecohydrological disturbances associated with roads: Current knowledge, research needs, and management concerns with reference to the tropics

et al. 2017

Roads are a pervasive form of disturbance with potential to negatively affect ecohydrological processes. Some of the most rapid growth in road networks is occurring in developing countries, particularly in the tropics, where political agendas are often focused on strengthening the economy, improving infrastructure, bolstering national security, achieving self‐sufficiency, and increasing citizen well‐being, often at the expense of the environment. We review what is known about road impacts on ecohydrological processes, focusing on aquatic systems, both temperate and tropical. We present seven cases that represent the broader trends of road development and impacts in tropical settings. Many of these process dynamics and impacts are not different from those experienced in temperate settings, although the magnitude of impacts in the tropics may be amplified with intense rainfall and lack of best management practices applied to road construction/maintenance. Impacts of roads in tropical settings may also be unique because of particular organisms or ecosystems affected. We outline a set of best practices to improve road network management and provide recommendations for adopting an agenda of research and road management in tropical settings. Importantly, we call for incorporation of transdisciplinary approaches to further study the effects of roads on ecohydrological processes in the tropics. Specific emphasis should also be placed on collaboration with governments and developers that are championing road development to help identify the drivers of road expansion and thresholds of negative impact, as well as methods of sustainable road construction and maintenance.
