description | The growth in urbanization and industrialization is causing an increase in environmental pollution in cities and their surrounding areas. Additionally, the growing urban population requires a greater volume of fresh vegetables. In nature, heavy metals (HM) are widely distributed; when they gradually enter the soil-plant-consumer continuum, they are difficult to remove from the system and accumulate at toxic levels. To gain an overview of this situation, the information in the ScienceDirect database was used in accordance with the PRISMA guide. For this, the keywords “vegetable”, “contamination” and “urban” were used in a first step and, in a second step, the keywords “vegetable” and “heavy metal” were used. The most toxic HM for consumers are Cd, Pb, Hg, Cr and As, as well as essential MP for the plant (Zn, Cu, Ni, Fe, Mo). At excessive concentrations these cause neurological and kidney damage, cancer and other forms of damage to health. Crop contamination can come from the atmosphere, irrigation water, and/or the soil itself, proximity to busy roads, industry, polluted rivers, and excessive use of pesticides and fertilizers that contain HM. Plant poisoning by HM causes a decrease in root growth and biomass of the plant, foliar chlorosis, and other physiological alterations. Leafy vegetables (including aromatic herbs) and solanaceous vegetables accumulate the most HM, while cucurbits and legumes are the least affected. Plants that develop for a longer time accumulate a greater amount of HM. In general, to increase the food safety of urban horticulture, more studies are needed on HM contamination, soil aptitude, risk assessment for ingesting intoxicated vegetables, as well as appropriate instructions for the clean handling of these crops in cities and surrounding areas. |

La creciente urbanización e industrialización genera un aumento de la contaminación del ambiente en las ciudades y terrenos aledaños, en cambio, la crecida población urbana demanda un mayor volumen de hortalizas frescas. En la naturaleza, los metales pesados (MP) existen ampliamente distribuidos y cuando entran paulatinamente al continuo suelo-planta-consumidor se pueden retirar difícilmente del sistema, acumulándose a niveles tóxicos. La información de la base de datos ScienceDirect se utilizó de acuerdo con la guía PRISMA, utilizando en primera instancia las palabras clave “vegetable”, “contamination” y “urban”, y en una segunda búsqueda los términos “vegetable” y “heavy metal”. Los MP más tóxicos para los consumidores son el Cd, Pb, Hg, Cr y As, igualmente como concentraciones excesivas de los MP esenciales para la planta (Zn, Cu, Ni, Fe, Mo) que ocasionan, entre otros, daños neurológicos, renales y cáncer. La contaminación de los cultivos puede venir de la atmósfera, el agua de riego y/o del suelo, sobre todo por la cercanía a las carreteras muy transitadas, la industria, ríos contaminados y el uso excesivo de pesticidas y fertilizantes que contienen MP. La intoxicación vegetal por MP causa una disminución en el crecimiento de las raíces y en la biomasa de la planta, además por clorosis foliar, entre otras alteraciones fisiológicas. Las hortalizas de hoja (incluyendo las hierbas aromáticas) y las solanáceas son las que más acumulan MP, mientras las cucurbitáceas y leguminosas son las menos afectadas. Las plantas que se desarrollan durante más tiempo acumulan una mayor cantidad de MP. En general, para aumentar la seguridad alimentaria de la horticultura urbana, faltan estudios sobre la contaminación con MP, la aptitud de los suelos, la evaluación del riesgo por ingerir hortalizas intoxicadas y, además, de instrucciones apropiadas para el manejo limpio de estos cultivos en las ciudades y zonas aledañas.
