Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Resumen El aumento poblacional y consecuentemente la alta demanda en los procesos de industrialización de diferentes complejidades, ha causado diversas problemáticas de carácter ambiental como el aumento en la concentración de metales pesados, que causan variados efectos sobre la salud, en diferentes matrices ambientales, particularmente agua que constituye por lo general el primer destino de vertimientos, agua que particularmente en el caso colombiano es usada para riego en suelos de cultivo. De acuerdo a esto, en el presente estudio se analizaron suelos de cultivo de los municipios de Sibaté, Tenjo, Mosquera, Facatativá, Siberia, en el departamento de Cundinamarca, y la localidad de Bosa de la ciudad de Bogotá, Colombia, influenciados por el cauce del río Bogotá, midiendo las concentraciones de cromo, cadmio, plomo y níquel por espectrofotometría de absorción atómica con horno de grafito. Para evaluar el grado de contaminación se calculó el índice de geoacumulación, encontrando que los suelos están clasificados como moderada y extremadamente contaminados, particularmente en contenidos de cromo en todas las zonas de muestreo estudiadas, y de plomo y cadmio en la zona de Sibaté. Se recomienda analizar los contenidos en vegetales para evaluar el efecto en las cadenas tróficas.
