“…The bioavailability of Hg in rice is not known but adverse effects including neurobiological disruptions and increase of c-fos gene expression have been observed in rats feeding experiments with MeHg contaminated rice Ji et al, 2006). The probable daily intake (PDI) of MeHg from rice consumption indicated potential human health risk in Hg mining areas Li et al, 2011;Zhang et al, 2010b). The MeHg translocation and accumulation in rice plant (Meng et al, 2010 and the effects of mitigation methods and cultivar variations (Peng et al, 2012;Rothenberg et al, 2011) were observed.…”

“…La forma más tóxica es el metil mercurio [CH 3 Hg] + , ya que se absorbe en un 90 % comparado con el cloruro de mercurio (HgCl 2 ) del cual solamente se absorbe un 2 % (UNEP 2013). Algunos de los efectos en la salud consisten en daños a diferentes órganos, principalmente el cerebro y los riñones, además de causar trastornos al sistema nervioso (Li et al 2011).…”

Palabras clave: remediación, microorganismos, suelos RESUMEN La contaminación por metales pesados en México es un problema que va en aumento debido a la actividad antrópica, específicamente la minería. Los metales contaminantes más importantes en México, dada su toxicidad y abundancia son: mercurio, arsénico, plomo y cromo. Entre los sitios más afectados por las altas concentraciones de metales pesados en suelos se encuentran los estados de Zacatecas, Querétaro, Hidalgo y San Luis Potosí. Una alternativa para contribuir a la solución de este problema, es el uso de especies vegetales para la remoción de metales pesados del suelo o "fitorremediación". Al respecto, en México se han caracterizado especies con capacidad de acumulación de metales, como Scirpus americanus, Typha latifolia, Jatropha dioica, Eichhornia crassipes y Amaranthus hybridus. Una estrategia para mejorar el proceso de fitoextracción de metales es a través de la inoculación de microorganismos del suelo. Bacterias de los géneros Rhizobium, Agrobacterium, Arthrobacter, Microbacterium, Curtobacterium, Rhodococcus, Xanthomonas y Pseudomonas, han mostrado resultados promisorios al ser empleados en estos tratamientos, así como el uso de hongos micorrízicos arbusculares específicamente del género Glomus. Sin embargo, son necesarios más estudios para optimizar los sistemas de tratamiento basados en la selección de las mejores plantas y bacterias endémicas de los sitios contaminados.Key words: remediation, microorganisms, soils ABSTRACT Heavy metal pollution is a growing problem due to anthropic activities such as mining. The most hazardous metals in Mexico are mercury, arsenic, lead, and chromium. States like Zacatecas, Querétaro, Hidalgo, and San Luis Potosi have been affected by the pollution of soils with heavy metals. In this sense, phytoremediation has emerged as an alternative to solve this problem. In Mexico, plant species with metal accumulative capacity have been identified. These include Scirpus americanus, Typha latifolia, Jatropha dioica, Eichhornia crassipes and Amaranthus hybridus. Metal phytoextraction could be improved by coupling bioaugmentation of soil microorganism. Bacteria from the genus Rhizobium, Agrobacterium, Arthrobacter, Microbacterium, Curtobacterium, Rhodococcus, Xanthomonas and Pseudomonas, have shown promising results enhancing Rev. Int. Contam.

“…Both inorganic and organic mercury is found in biological objects, its toxicity being different. Organic mercury comes in a hair through its follicle in proportion to the mercury content in the blood, whereas almost no inorganic mercury gets to hair in this way.…”

Mercury in archeological hair samples from Xiongnu burials (Noin‐Ula, Mongolia): SR XRF and CXRM analysis

A technique has been developed for determining mercury content in the concentration range of 1–1000 μg/g in hair samples by X‐ray fluorescence analysis using synchrotron radiation (synchrotron radiation X‐ray fluorescence, Siberian Synchrotron and Terahertz Radiation Center, Budker Institute of Nuclear Physics SB RAS). The mercury content was identified in archeological hair samples from an ancient burial of Xiongnu nobility (Mongolia, mound 22, 1st century BC–1st century AD); the content values were elevated (up to 1100 μg/g) in all the samples (n = 41). An X‐ray microanalysis using polycapillary lenses in a confocal scheme (confocal X‐ray microscopy station) was developed at the Synchrotron radiation X‐ray fluorescence to establish mercury distribution in a cross section of hair shaft with a spatial resolution of 5 μm. The findings of the study make it possible to assume exogenous income of mercury (from the burial environment) to the hair.
