“…Lettuce is used for toxicity assessment in moderate pH environment (pH 6-8) (ISO 2005b;Sheppard et al 1993;Chapman et al 2010Chapman et al , 2012 because it is not a good acid-tolerant species (Chapman et al 2012;Environment Canada 2005). Among higher plants, oat is recommended for toxicity tests of heavy metals (Chang et al 1997;ISO 2005a) under low pH conditions (Loureiro et al 2006;Small and Jackson 1949;Bilski and Foy 1987), while Allium cepa is Pb tolerant in acidic environment (Dang et al 1990).…”

Heavy metal contamination is a globally recognized environmental issue, threatening human life very seriously. Increasing population and high demand for food resulted in release of various contaminants into environment that finally contaminate the food chain. Edible plants are the major source of diet, and their contamination with toxic metals may result in catastrophic health hazards. Heavy metals affect the human health directly and/or indirectly; one of the indirect effects is the change in plant nutritional values. Previously, a number of review papers have been published on different aspects of heavy metal contamination. However, no related information is available about the effects of heavy metals on the nutritional status of food plants. This review paper is focused upon heavy metal sources, accumulation, transfer, health risk, and effects on protein, amino acids, carbohydrates, fats, and vitamins in plants. The literature about heavy metals in food plants shows that both leafy and nonleafy vegetables are good accumulators of heavy metals. In nonleafy vegetables, the bioaccumulation pattern was leaf > root ≈ stem > tuber. Heavy metals have strong influence on nutritional values; therefore, plants grown on metal-contaminated soil were nutrient deficient and consumption of such vegetables may lead to nutritional deficiency in the population particularly living in developing countries which are already facing the malnutrition problems.

“…La toxicidad en la L. sativa generada en el tratamiento ZnW (Tabla 3), se presentó de manera moderada en el Andisol, periodo 1, debido posiblemente a que la lechuga es sensible al pH ácido de la solución de dicho tratamiento, lo cual inhibe su crecimiento y metabolismo celular (Chapman et al 2012). …”

“…Para evaluar el riesgo ecológico que puede ocurrir en suelos contaminados por metales pesados se realizan bioensayos que integran la exposición y los efectos de los contaminantes, que permiten representar sus interacciones con las diferentes propiedades físico-químicas y/o biológicas del suelo y evaluar los efectos de sus mezclas tanto en plantas como microorganismos (Chapman et al 2012). …”

Evaluación de la toxicidad de metales pesados en dos suelos agrícolas de Colombia mediante bioensayos

La presente investigación tuvo como objetivo determinar la toxicidad de Cu, Cd, Ni, Pb y Zn, en dos suelos agrícolas colombianos, Andisol y Vertisol, mediante bioensayos con Lactuca sativa y Vibrio fischeri. Los metales se adicionaron individualmente a los suelos hasta superar el nivel de intervención de Andalucía. Posteriormente se incubaron a 25 °C y 60% de humedad, durante 60 y 90 días, respectivamente. El diseño experimental fue un completamente al azar con tres repeticiones. Luego de cada incubación se determinó la concentración de los metales en extractos acuosos, y con ellos se efectuaron bioensayos con Lactuca Sativa y Vibrio fischeri. Se efectuó análisis estadístico de resultados, comparaciones post hoc (Tukey), correlaciones y análisis de componentes principales, para encontrar los factores que afectaron los organismos en estudio. Se encontró que el Vertisol presentó mayor capacidad de inmovilización de los metales, en función de su contenido de arcillas y pH neutro, lo cual se reflejó en menor toxicidad sobre las especies en ensayo, indicando que este suelo actuó como protectante contra la movilidad de contaminantes en solución del suelo. El ensayo con V. fischeri presentó mayor sensibilidad a los contaminantes, permitiendo una mejor discriminación de los niveles de toxicidad. La capacidad de ambos suelos de inhibir la toxicidad se incrementó con el tiempo, posiblemente por interacción de los metales con los diferentes componentes de los suelos, y la disminución de su movilidad por mecanismos como la formación de complejos estables, y se relacionó con el incremento del pH.

“…In some cases, this sensitivity can overshadow the toxicity of the hazardous elements of concern. (Frouz et al, 2011;Chapman et al, 2012). Thus, undiluted samples of S2 and S3 caused a 100% inhibition of radish emergence, whereas in diluted samples of these soils, effects on emergence were not observed.…”

“…To have a more complete impression of the degree of pollution and toxicity of a contaminated site, it is recommended to consider alternative approaches that more accurately reflect specific site conditions. Thus, risk assessment in mining sites should integrate both chemical and toxicological assays (Antunes et al, 2011;Chapman et al, 2012).…”

The toxicity of As and heavy metals from mining soils to soil and aquatic organisms was studied using the Multispecies Soil System (MS-3) in soil columns. Ecotoxicological assessment was performed with soil samples diluted with a control soil at concentrations of 12.5, 25, 50 and 100% test soil/ soil (w/w). In this way, changes in the mobility and bioavailability of soil contaminants due to changes in geochemical soil properties via soil dilution were studied. The toxicity of water samples was tested on algae and Daphnia magna. The assessment of the mining area indicated that the current presence of As and heavy metals at the site may cause injuries to soil and aquatic organisms in the entire research area. Moreover, this investigation demonstrated that changes in geochemical conditions can increase the availability of arsenic and, consequently, the environmental risk of these soils. A good correlation was not found between toxicity parameters and the concentrations of soil contaminants based on total and extracted element concentrations. This finding reinforces the usefulness of direct toxicity assays for evaluating environmental risk.
