Tendencias metodológicas en la evaluación del grado de contaminación y de riesgos por metales pesados presentes en sedimentos viales urbanos

Abstract: El objetivo principal de este artículo es analizar las tendencias a nivel mundial en el uso de métodos para evaluar la contaminación por metales pesados (MP) asociados con el sedimento vial (SV) urbano. Se realizó una revisión sistemática de literatura entre los años 1995-2018. Se empleó un índice de frecuencia de citación con el fin de establecer un orden de importancia para las categorías detectadas. Los resultados muestran el siguiente ordende importancia para las categorías detectadas: en… Show more

“…We excluded functional traits such as crown size, plant area index, and canopy morphology, to focus specifically on leaf macro-morphology. At this stage, a citation frequency index was considered [ 37 ] in the selected databases, where the importance associated with each keyword (variable) was organized by means of quartiles (Q) (e.g., for PM 2.5 in Scopus, 2335 documents were detected in Stage 2 within the 8181 documents detected in Stage 1, i.e., index = 2335/8181 = 0.285; see Table 1 ). This index had a variation between 0.00–1.00, where the last quartile (Q4 = 0.00–0.25) associated keywords with the lowest citation frequency.…”

“…Los metales pesados de mayor relevancia son Pb (97,4 %), Cu (93,5 %) y Zn (89,6 %). No obstante, también se destacan Cr, Cd, As por su elevado riesgo ecológico y cancerígeno, lo que demuestra el efecto de los metales en el ambiente [1].…”
