| Abstract (English): |
Urban and periurban agriculture may imply risks for human health if it is not appropriately conducted. The objective of this contribution was to present a survey of heavy metal content in horticultural soils of Buenos Aires. The information is compared to national and international quality standards, and enrichment factors for heavy metals were calculated with reference to Dutch values. With reference to earth crust, Cd, Pb, Cu and Zn were increased. Mean and maximum enrichment factors were higher for Cu, Pb, Cd and Zn. Horticultural urban and periurban soils must be carefully monitored considering risk of metal input in food chain. [ABSTRACT FROM AUTHOR] |

La agricultura urbana y periurbana puede implicar riesgos para la salud humana, si no es adecuadamente manejada. El objetivo de esta contribución fue presentar un relevamiento de minerales pesados en suelos hortícolas de Buenos Aires. La información se comparó con estándares de calidad nacionales e internacionales, y se calcularon factores de enriquecimiento con referencia a estándares holandeses. Con respecto a la corteza terrestre, el Cd, Pb, Cu y Zn se incrementaron. Los factores medios y máximos de enriquecimiento fueron mayores para Cu, Pb, Cd y Zn. Los suelos hortícolas urbanos y periurbanos deben ser cuidadosamente monitoreados considerando el riesgo de entrada de metales en la cadena alimentaria. [ABSTRACT FROM AUTHOR] |
