    Basado en la revisión sistemática de 32 artículos publicados en PubMed-Medline hasta enero del 2006 y utilizando como palabras clave DDT exposure, human, milk y Mexico; este estudio analiza la situación acerca de la exposición en México a difenildicloroetano (DDT) y su principal metabolito p,p,'-DDE, así como, su posible repercusión sobre la salud humana. Aún cuando, el uso del DDT se suspendió en 1999, los estudios evaluados reportan niveles importantes de p,p'-DDE, en muestras biológicas de suero, tejido adiposo y leche materna de poblaciones no ocupacionalmente expuestas. Así mismo, existen evidencias sobre daños a la salud, especialmente relacionados con el área reproductiva masculina, la lactancia materna y más recientemente daños a nivel celular, así como, alteración en el desarrollo psicomotor de niños expuestos in utero. Aún cuando existen muchas lagunas, acerca de otros efectos adversos a la salud relacionados con la exposición a DDT o sus metabolitos, la experiencia lograda hasta ahora, debe ser tomada en cuenta en México y el resto de Latinoamérica, para que considerando el principio precautorio se legisle sobre el DDT y otros contaminantes orgánicos persistente que tienen actividad y características similares al DDT o sus metabolitos.<br>Based on the systematic revision of 32 articles published in PubMed-Medline until January of 2006 and using like key words DDT exposure, human, milk and Mexico; this study analyzes the situation about the exposure of difenildicloroetano (DDT) and its main metabolite p,p,'-DDE in Mexico, as well as, their possible repercussion on the human health. Even though, the use of the DDT in Mexico was banned in 1999, the evaluated studies report significant levels of p, p'-DDE, in biological samples of serum, adipose tissue and maternal milk of populations not occupationally exposed. Also, there are evidences on damages to the health, specially related to the reproductive area, and more recently damages at cellular level, as well as, alteration in the psychomotor development of children exposed in uterus. Even though many gaps exist concerning the other adverse effects on health, relating to DDT exposure and its metabolites, experience accumulated at this point, must be taken into account in Mexico and the rest from Latin America, so that following this precautionary principle they should legislate against DDT and other persistent organic contaminants with characteristics similar to those of DDT and its metabolites

    Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

    No full text
    International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
