The purpose of this work is to address an environmental problem in Mexico, which uses significant amounts water for agricultural activities, where atrazine frequently used as a pesticide weed control. Currently, there no law prohibiting its use, even though it considered endocrine disruptor some mammals and harmful health. Due the difficulty direct quantification several herbicides, present low concentration water, aims develop optimization validation preconcentration with magnetic stir bars...
Abstract In the mining district of Zimapán, located in State Hidalgo, Mexico, high concentrations potentially toxic elements such as arsenic (As), lead (Pb), and cadmium (Cd), Acid Mine Drainage (AMD) have been detected tailing’s dams. This AMD, along with population growth region, has reduced distance between waste sites urban areas, increasing risk exposure to these contaminants for living organisms. The objective this study was evaluate AMD generation human health ecosystem due potential...
Glyphosate is a herbicide of wide spectrum that alters the production amino acids in plants, leading to their death. Due its properties, it used eliminate weeds interfere with human activity. The intensive use this past decades has led frequent encounter environment as been detected water, animals, and food destined for consumption. Its impact on health rest living organisms not fully explored, given many authors enter into contradictions one another, specifically surrounding role...
Lake Tziscao is one of the water bodies belonging to Lagunas de Montebello National Park, located in south-southeastern part state Chiapas, Mexico. Its importance lies its great tourist activity due size and nearby human settlement, which why there are numerous anthropogenic factors that promote transformation natural areas within it.In this work, PHREEQC software was used perform inverse hydrogeochemical modeling, with predominant processes site were identified estimated using 20 sampling...
Despite the fact that use and application of most organochlorine pesticides has been prohibited in Mexico, these are still used several cultivation areas, such as Xochimilco´s Chinampera area, specifically Apatlaco Ampampilco canals. Consequently, this study reports data found canals a comparison made with respect to PWC modeling international standards. The above-mentioned program estimates concentrations should be if were applied according recommendations. aim paper is explain what happens...
The “Lagunas de Montebello” National Park located in Chiapas, Mexico, is well known for its crystal blue water bodies, some of which, 2003, started to change color from crystalline cloudy brown, and occasionally emit a foul smell, contains white-yellowish supernatant debris dead fish. To determine the causes changes characteristics “Liquidambar” lagoon Montebello system, physicochemical characterization was carried out over first six meters column, together with geochemical speciation...
