“…However, the rapid economic growth over the past two decades in this region has brought significant environmental problems, including encroachment on agricultural land, soil erosion, and pollution. Previous studies conducted in Dongguan found that the arable land decreased from 30,816 ha in 2004 to 24,800 ha in 2012, whereas concentrations of heavy metal in soils from urbanized areas of Dongguan increased by 28.6% for Cd, 33.0% for Cu, 16.2% for Ni, and 55.9% for Zn [24,43,44]. Many researchers have reported that Cd, Cu, and Zn were the major contaminants in topsoils surrounding industrial plants [10,12,44].…”

Exponential industrialization and rapid urbanization have resulted in contamination of soil by metals from anthropogenic sources in Dongguan, China. The aims of this research were to determine the concentration and distribution of various metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn)) in soils and identify their potential health risks for local residents. A total of 106 soil samples were collected from the vicinity of industrial sites in Dongguan. Two types of samples were collected from each site: topsoil (0–20 cm, TS) and shallow soil (20–50 cm, SS). Results showed that the soils were contaminated by metals and pollution was mainly focused on TS. The geoaccumulation index (Igeo) and pollution indexes (PI) implied that there was a slight increase in the concentrations of Cd, Cu, Hg, Ni, and Pb, but the metal pollution caused by industrial activities was less severe, and elements of As and Cr exhibited non-pollution level. The risk assessment results suggested that there was a potential health risk associated with As and Cr exposure for residents because the carcinogenic risks of As and Cr via corresponding exposure pathways exceeded the safety limit of 10−6 (the acceptable level of carcinogenic risk for humans). Furthermore, oral ingestion and inhalation of soil particles are the main exposure pathways for As and Cr to enter the human body. This study may provide basic information of metal pollution control and human health protection in the vicinity of industrial regions.

“…The pollution load index values are used to classify samples as; unpolluted (PLI 1), moderately polluted (PLI = 1 3), highly polluted (PLI = 3 5) or very highly polluted (PLI > 5) (Qing et al, 2015). The pollution load index has been calculated and ranged from 0.06 to 0.54 and its mean is 0.163, i.e.…”

“…La capacidad de nuestras sociedades para alcanzar y mantener en el tiempo unas condiciones habitacionales coherentes con el derecho a un hábitat digno, está inevitablemente vinculada a los mecanismos de generación de nuestras viviendas, barrios y ciudades, pues depende directamente de los recursos disponibles y de la capacidad de emisión de residuos (Arcas-Abella et al, 2011). En relación a este último aspecto, los organismos de investigación mundial en urbanismo, ambiente y salud pública reportan el interés creciente de estudiar la contaminación por metales pesados en hábitats urbanos, debido a su continua emisión, los largos periodos de residencia en el ambiente, el transporte dentro de las masas de aire, su deposición sobre la superficie, y a que son significativamente móviles y potencialmente biodisponibles (Qing et al, 2015).…”

ResumenLos organismos de investigación en urbanismo, ambiente y salud pública reportan el interés creciente de estudiar la contaminación por metales pesados (MP) en hábitats urbanos. Se presenta un estudio observacional descriptivo de las concentraciones de MP en sedimentos viales de un hábitat urbano latinoamericano: Bogotá-Colombia. Existió coincidencia entre las concentraciones de MP reportadas a nivel mundial y las observadas en Bogotá. Las concentraciones en Bogotá tendieron a ser inferiores a las reportadas en ciudades de Norteamérica-Europa-Asía. El elemento más crítico fue el Pb. Este metal superó entre 1,02-4,30 veces el límite legislativo de referencia más exigente por ingestión, inhalación y contacto dérmico (Cataluña-España: 60 mg/kg). Durante periodos climáticos de tiempo seco se observaron incrementos en las concentraciones de MP, entre 1,31-2,11 veces. Los hallazgos se constituyen en un punto de referencia durante el desarrollo de estrategias para la protección de la salud pública y el ambiente en hábitats urbanos.Palabras clave: hábitats urbanos, metales pesados, salud pública. AbstractResearch agencies in urban planning, environment, and public health report the growing interest of studying the pollution by heavy metals (HMs) in urban habitats. A descriptive observational study of the HM concentrations in road sediments of an urban habitat in Latin America is displayed: Bogota-Colombia. There was a coincidence between the HM
