Resumen
Han sido y forman parte de muchas actividades laborales a nivel industrial, agrícola, minero, etc. Forman parte de la naturaleza y tienen una permanencia por años en el ambiente, se encuentran en suelos, agua y aire a distintas concentraciones, las plantas al obtener sus nutrientes necesarios pueden llevar consigo también metales pesados, mismos que a su vez los animales consumen o las personas directamente. Son bioacumulables, es decir; se acumulan en el organismo con el paso del tiempo a determinada concentración ocasionando deterioro en la salud y comprometiendo órganos vitales debido a su exposición.
En el sector “Cárcel” cantón Montecristi-Manabí ciertos habitantes poseen plantaciones de ruda (Ruta graveolens) que emplean por su numerosos beneficios, estas plantas se encuentran cercanas y a exposición de una fábrica artesanal de ladrillos, uno de los pasos para la obtención de estos productos es la incineración constante contaminando de este modo el ambiente en general.
Se evaluó la existencia en dicho proyecto de investigación de dos metales pesados (plomo y cadmio) así como su concentración en las hojas de ruda a través de la técnica de espectrofotometría (absorción atómica en llama específicamente). Resoluciones de este análisis mostraron concentraciones inferiores del Límite de cuantificación (LOQ) para plomo <6.25mg/Kg y para cadmio <1.25 mg/Kg. Además, se realizó una semejanza con los valores máximos permisibles, principalmente de la Norma Técnica Ecuatoriana NTE INEN- Codex Alimentarius 193:2013 y la Normativa General Internacional de La Unión Europea, en donde pueden estar dentro del rango permisible no resultando una amenaza grave que pueda comprometer la salud de los habitantes, sin embargo; se considera determinar su concentración y detección con un método mucho más sensible.
They have been and are part of many labor activities at an industrial, agricultural, mining, etc. level. They are part of nature and have a permanence for years in the environment, they are found in soils, water and air at different concentrations, when plants obtain their necessary nutrients they can also carry heavy metals, which in turn are consumed or consumed by animals people directly. They are bioaccumulative, that is, they accumulate in the body over time at a certain concentration, causing deterioration in health and compromising vital organs due to their exposure. In the "Carcel" sector, Montecristi-Manabí canton, certain inhabitants have plantations of rue (Ruta graveolens) that they use for their numerous benefits, these plants are nearby and exposed to an artisan brick factory, one of the steps to obtain these products is constant incineration, thus contaminating the environment in general. The existence of two heavy metals (lead and cadmium) was evaluated in this research project, accompanied by its concentration on rue leaves through the spectrophotometry technique (specifically flame atomic absorption). Resolutions of this analysis showed lower concentrations the Limit of Quantification (LOQ) were found for lead <6.25mg/Kg and for cadmium <1.25mg/Kg. In addition, a similarity with the maximum permissible values was performed mainly of Ecuadorian Technical Standard NTE INEN- Codex Alimentarius 193:2013 and the International General Standard of the European Union, where they may be within the permissible range, not resulting in a serious threat that can compromising the health of the inhabitants, however, it is considered to determine its concentration and detection with a much more sensitive method.
