“…Road surfaces serve as sinks and sources of metals and other contaminants in urban environments (Deletic and Orr, 2009;Yuen et al, 2012). Elevated concentrations of metals are ubiquitous in road-deposited sediment (RDS) owing to a wide range of human activities including vehicle emissions, coal combustion, disintegration of vehicle brakes and tires, atmospheric deposition, road surface wear, municipal solid waste incineration, and residential heating (Andrews and Sutherland, 2004;Duzgoren-Aydin, 2007;Eriksson et al, 2007;Duong and Lee, 2009).…”

“…Por otro lado, el análisis climático de la concentración de metales pesados del sedimento vial se realizó para la fracción de tamaño inferior a 250 μm. Lo anterior, debido a que las investigaciones han reportado que esta fracción tendió a registrar las mayores concentraciones metálicas (5,16,19,20,23,24).…”

“…A partir de lo anterior, el incremento local de las investigaciones sobre los entornos viales urbanos está asociado con el interés de evaluar el comportamiento temporal del material atmosférico en suspensión, hidrocarburos y metales pesados (12)(13)(14); sus efectos tóxicos sobre la salud pública, las estrategias de limpieza de las fuentes de polución, y las cargas descargadas en los sistemas acuáticos, el suelo y la atmósfera. Es por esto, que en algunas investigaciones se han utilizado a los sedimentos viales como indicadores de la presencia de metales pesados en la superficie de ambientes urbanos (15,16).…”

“…The main contributors include weathering of rocks and soils and multiple anthropogenic activities resulting discharge of industrial and urban wastes into water bodies (Singh et al, 2005). Among these pollutants, heavy metals have been of great concern due to their toxicity, abundance, persistence, and subsequent accumulation in aquatic habitats (Kaushik et al, 2009;Lin et al, 2003;Singh et al, 2005;Yuen et al, 2012). These adsorbed contaminants may be later released into the water column with changing environmental conditions and may pose a threat to biota (Junhong et al, 2011).…”
