“…As pointed out by Temple et al (1981), the major limitation is that the collection efficiency of moss bags for various contaminants have not been determined, thus, "data from moss bag surveys reflects relatives rate of deposition but cannot be used to define total atmospheric loading of contaminants". Although there have been many published studies using the moss bag method to assess atmospheric metal deposition, there are remarkably few critical studies (Tavares and Vasconcelos, 1996;Vasconcelos and Tavares, 1998;Spagnuolo et al, 2013;Ares et al, 2015). Despite some crucial limitations, Clough (1975) found that, overall, moss bags are representative of deposition to plants.…”

“…Como se observa en los resultados del cuadro III, y de acuerdo con el análisis estadístico de Wilcoxon (p < 0.05), hay diferencias entre la concentración previa y posterior al periodo de exposición, siendo esta última mayor. Esto permite demostrar que L. angustata es un buen acumulador de metales aerotransportados, lo cual es esencial en la técnica de monitoreo activo con bolsas con musgo (Ares et al 2015, Vuković et al 2015. La concentración obtenida después del periodo de exposición -a excepción de los musgos de los sitios de Tollocan y San Mateo Atenco-muestra la siguiente tendencia: Zn > Cu > Pb.…”

El objetivo de este trabajo fue evaluar los niveles de Cu, Zn y Pb en la zona metropolitana del valle de Toluca (ZMVT) empleando la técnica de biomonitoreo activo con bolsas con musgo (moss bags) con Leskea angustata como bioindicador, así como determinar si se producen fitoquelatinas (PC) y si hay correlación entre la concentración de éstas y de glutatión (GHS) con los metales presentes en el musgo. Se seleccionaron 10 sitios de monitoreo y en cada uno se colocaron dos bolsas con musgo para ser expuestas al ambiente de la ZMVT durante seis meses. Las concentraciones de metales se determinaron mediante la técnica de fluorescencia de rayos x en reflexión total (TXRF), mientras que el GHS y las PC se cuantificaron empleando la técnica de cromatografía de líquidos de ultra alta resolución acoplada a espectrometría de masas (UPLC-MS). Se evaluó la concentración de metales, PC y GHS antes y después de la exposición y se calculó la tasa de enriquecimiento. Los resultados muestran enriquecimientos de 2 a 30 para metales y de 116 a 569 para GHS. La concentración de PC siempre fue menor al límite de detección. El orden de la concentración total de metales en los sitios de monitoreo fue: Tollocan > Reforma > San Mateo Atenco > Alameda > Aeropuerto > San Cristóbal > Metepec > Ceboruco > Toluca Centro > Oxtotitlán. En general Tollocan, San Mateo Atenco, Alameda y Reforma fueros significativamente diferentes a los demás sitios. El GHS presentó un rango de concentración de 164 a 808 nM/g y presentó correlaciones positivas (r = 0.8) con el Cu, Zn y Pb, por lo que se infiere que la concentración de los metales en estudio tiene relación directa con su inducción. Con los resultados obtenidos en este trabajo se pude concluir que el GHS desempeña un papel fundamental en la bioacumulación de metales divalentes en Leskea angustata de la ZMVT e incrementa su potencial de acumulación, ya que es un mecanismo importante de destoxificación en estos organismos.

“…So, the concentration of elements in the moss's tissues reflects the atmospheric heavy metal deposition. Finally, this technique is so useful for monitoring the air particulate matter quality and also an economical environmental tool (Aničić et al 2009 ; Ares et al 2015 ).…”

The metropolitan area of the Toluca Valley (MATV) extends over an area of 1208.55 km2 and has 1,361,500 inhabitants making it the fifth highest populated area in the country and the second highest in the state. The MATV has several environmental problems, with regards to the air quality. Particles PM10 and PM2.5 are considered to be the main pollutant due to these particles frequently exceeding the limit laid down in the standards of the air quality in the country. For this reason, samples of the mosses Fabriona ciliaris and Leskea angustata were collected at different sites in MATV, Mexico in order to establish the atmospheric deposition of heavy metals by means of the analysis of the mosses tissues. Results show the average metal concentrations in the mosses in the order of: Zn > Pb > Cr > Cd. The concentration capacities of heavy metals were higher in Fabriona ciliaris than Leskea angustata. Enrichment factors for Cr, Zn, Pb and Cd were obtained using the soils from the same sampling area. Enrichment factors results show that Cr is conservative in both sampling seasons with a terrigenous origin; Zn is moderately enriched in both sampling seasons and mainly associated to pedological-soil or substrate contribution and anthropogenic activities and Cd is highly enriched in the rainy season and Pb is highly enriched in both sampling seasons, with a predominantly anthropogenic origin. This study provides information to be considered in the strategies for similar environmental problems in the world.
