Desarrolla una alternativa de fitoextracción usando Amaranthus caudatus en los suelos contaminados de los Grandes Parques de Lima Metropolitana (GPLM): Bosque El Olivar, Campo de Marte, Pentagonito, Zoológico de Huachipa, Las Leyendas y Kennedy. Para ello se determinó el contenido total de plomo en los suelos y agua de riego de los GPLM siguiendo las pautas dadas por la guía para muestreo de suelos (Ministerio del Ambiente [MINAM], 2014). Los valores promedio de plomo total en los suelos de los GPLM como Bosque El Olivar (170 ppm Pb), Campo de Marte (226 ppm Pb) y Pentagonito (159 ppm Pb) estuvieron por encima de lo permitido por los Estándares de Calidad Ambiental (ECA-Perú:140 ppm). En el parque Las Leyendas se determinó que ocho de las 98 hectáreas estaban contaminadas (234.5 ppm Pb) y en el Zoológico de Huachipa 0.7 de las 11 hectáreas (266 ppm Pb) sobrepasaron el límite E...

Alluvial gold mining in the Peruvian Amazon has become a key driver of land degradation and deforestation. The associated release of mercury in the environment poses direct human health risks and is likely to engender cascading effects throughout local food chains. We carried out research in an alluvial gold mine concession in the Madre de Dios region to compare the degree of soil-borne pollution of heavy metals in areas where mining operations were abandoned more and less recently (1–5 and 6–8 years ago, respectively) with non-impacted old-growth forest areas. All heavy metals, were below permissible levels according to Peruvian and Canadian environmental quality standards. Mean As, Ba, Pb, Cu, Cr, Ni, V and Zn concentrations in impacted areas were 1.90 ± 1.51, 29.80 ± 22.87, 4.60 ± 2.55, 12.68 ± 8.13, 7.90 ± 3.98, 7.93 ± 3.89, 12.67 ± 6.62, and 26.65 ± 13.53 mg kg−1 dry m...

The new coronavirus (COVID-19) is the latest virus to cause a pandemic, which affected and altered the health of the world’s population. Dentists were no strangers to research on this topic, they reported and publishedthe oral signs that were presented. This research aims to collect and organize information on COVID-19from the stomatological point of view, 25 articles were taken from journals in Scholar Google, Scielo, Pubmed and Elsevier, which were thoroughly reviewed. The article is the result of a search for information on this disease and its clinical manifestations, with emphasis on those that occur in the oral cavity, since the functional and structural changes caused by this disease are primarily visualized in this organ, so that every health professional should consider the absolute necessity of looking at the mouth. Because COVID-19 has a predilection for ACE2 receptors, loca...
