“…In both cases, this may be an effect of the rainy season as described by [60], who demonstrated that high-flow events caused by rains significantly reduced the richness of the macroinvertebrate assemblages. In the Extoraz river, lower FRic values may also reflect the effect of mining pressure (note the proximity of mining activities to the Extoraz river in Figure 1), mainly from mercury extraction in this area [61,62]. The Extoraz river showed significant differences in FRic values between February and July 2017; however, the low values recorded may be related to the local climate and type of vegetation in the basin.…”

Characterization of the Multidimensional Functional Space of the Aquatic Macroinvertebrate Assemblages in a Biosphere Reserve (Central México)

The analysis of functional diversity has shown to be more sensitive to the effects of natural and anthropogenic disturbances on the assemblages of aquatic macroinvertebrates than the classical analyses of structural ecology. However, this ecological analysis perspective has not been fully explored in tropical environments of America. Protected Natural Areas (PNAs) such as biosphere reserves can be a benchmark regarding structural and functional distribution patterns worldwide, so the characterization of the functional space of biological assemblages in these sites is necessary to promote biodiversity conservation efforts. Our work characterized the multidimensional functional space of the macroinvertebrate assemblages from an ecosystemic approach by main currents, involving a total of 15 study sites encompassing different impact and human influence scenarios, which were monitored in two contrasting seasons. We calculated functional diversity indices (dispersion, richness, divergence, evenness, specialization, and originality) from biological and ecological traits of the macroinvertebrate assemblages and related these indices to the physicochemical characteristics of water and four environmental indices (Water Quality Index, habitat quality, Normalized Difference Vegetation Index, and vegetation cover and land use). Our results show that the indices of functional richness, evenness, and functional specialization were sensitive to disturbance caused by salinization, concentration of nutrients and organic matter, and even to the occurrence of a forest fire in the reserve during one of the sampling seasons. These findings support the conclusion that the changes and relationships between the functional diversity indices and the physicochemical parameters and environmental indices considered were suitable for evaluating the ecological conditions within the reserve.

“…Zhang et al [46] reported 0.129-28.182 mg/kg and 0.001-2.673 mg/kg of mercury concentrations in soil and leaf, respectively. The highest mercury concentration in plant which accumulated in leaf is shown in data from the San Joaquín mining site, Mexico, which is 0.1-8.2 mg/kg Martínez-Trinidad [47]. This phenomenon occurred with the total mercury absorption in plant at a distance of between 0-7 km from the edge of the gold mining area to Palu.…”

Poboya, Central Sulawesi is one of the primary sites used for small-scale gold mining activities in Indonesia. Poboya consumes 200-500 kg of mercury/day by amalgamation. Palu, the capital city of Central Sulawesi, is a city with a population of 0.35 million people and located around 11 km away from the edge of a small-scale gold mining area in Poboya. Fifteen samples of upper layer soil and fifteen samples of plant (Calotropis gigantean) were taken along the road that connects Poboya to Palu, at every 500 m. Mercury concentration in the soil samples showed a gradual decrement as the distance from Poboya became greater. The plant samples also revealed a similar trend to the soil samples. The highest concentration of mercury in the soil was found at Poboya-i.e. 17.62 ng/mg, and the concentration of mercury in Calotropis gigantean grown at Poboya was 6.5 ng/mg. Based on the soil samples and pollution index, the data showed that the research area had heavy pollution levels up to 4 km. Moreover, the transfer factor was in the range of 0.13-3.44 at distances of 0-4 km, respectively.

“…The highest accumulation of trace metals in roots is a common pattern in many phytoremediation studies in Mexico (Carrión et al, 2012;Martínez-Trinidad et al, 2013, Mauricio et al, 2010Mireles et al, 2004). The distribution of PTE in roots or aerial parts is affected by variation in the organization of root tissues, the size of the metal influences its movement within plants, and the mobility rate in the transport of PTE from the root to aerial parts (Skorbiłowicz et al, 2016;Vaculík et al, 2012;Yabanli et al, 2014).…”

“…Mine tailings in Mexico also represent an important ecological problem due to the dispersion of pollutants (Cortés-Jiménez et al, 2013) (Covarrubias and Peña, 2017;González-Dávila et al, 2012;Hernández-Silva et al, 2012). In addition, intoxication by Hg in humans has been reported (Martínez-Trinidad et al, 2013).…”

FITORREMEDIACIÓN in situ EN MÉXICO: UNA REVISIÓN

et al. 2021

View full text Add to dashboard Cite

En México, la contaminación por elementos potencialmente tóxicos en el suelo y el agua representa importantes problemas ecológicos y de salud. Las plantas capaces de crecer en terrenos antropogénicamente modificados reflejan su capacidad de adaptación a diversas condiciones ambientales. La mayoría de los estudios de fitorremediación se lleva a cabo en condiciones de laboratorio, y sólo unos pocos estudios evalúan la capacidad de fitoextracción in situ. Esta revisión resume la información obtenida de fuentes científicas sobre los estudios de fitorremediación in situ realizados en México. El 85% de los estudios reportados corresponde a sitios contaminados con metales traza por actividades mineras. Se describen plantas con potencial para ser utilizadas como acumuladoras o hyperacumuladoras de elementos potencialmente tóxicos, como Hydrocotyle ranunculoides, Parietaria pensylvanica y Commelina diffusa para Zn; Rorippa nasturtium-aquaticum y Simsia amplexicaulis para Cu; Nicotina glauca, Flaveria angustifolia y Flaveria trinervia para As y Buddleja scordioides para la fitoremediación de suelos contaminados por Pb. Las especies de plantas nativas deben estudiarse para establecer mecanismos de fitoextracción de metales y la interacción agua-suelo-microorganismos para mejorar la eficiencia de la fitorremediación in situ. La información aquí descrita tiene utilidad para planificar la remediación de sitios contaminados por elementos potencialmente tóxicos en México y para diferentes sitios del mundo.
