As humanity evolves, air pollution has increased due to the various anthropogenic activities that man carries out, alienating emissions of gases and polluting particles to the environment, seriously affecting the health of living beings and the planet, since these cause Irreversible physical and chemical alterations in the environment, becoming a major problem worldwide. In Mexico there are meteorological stations that measure air quality and they are only found at fixed points, however, they do not cover all areas of the State of Mexico, the deterioration of air quality brings with it an increase in respiratory and cardiovascular diseases ; That is why this project's main objective is to build a portable electrochemical sensor using an Arduino board, using customizable software capable of quantifying and analyzing three polluting gases CO, CO2 and O3, especially in the municipality of Chimalhuacán located in the area East of the State of México.
The pollution of the planet has generated a series of problems for the environment and human health, such as the case of soils contaminated by heavy metals from batteries that are improperly disposed of in domestic garbage and sanitary landfills; Button batteries (HgO) pollute the soil, since mercury is very persistent in the environment due to its biomagnification and its great capacity to accumulate in organisms causing diseases in humans at the skin level, respiratory tract, digestive system, etc. . this being a highly toxic metal worldwide. The accumulation of Hg in soils depends on physicochemical factors such as pH, redox potential, organic matter, and clay. The main objective of this research work is to implement mercury phytoextraction in soils contaminated by button cells, using “Bamnusoideae” Bamboo, a UV-Vis spectroscopic study was carried out to determine the desorption of Hg from the contaminated soil, images of the stem were obtained, leaves and roots of bamboo without contamination and contaminated with Hg with a VE-B6 microscope, rating: 85V to 265V 50/60 Hz, Halogen Lamp: 12V 30W, and the pH of the contaminated soil was measured.
Biogas is a renewable biofuel product of anaerobic digestion, of the decomposition of organic matter (biomass) generating methane (CH4) with high energy value that represents 50 and 75% gas, it is an excellent ecological alternative in energy production, in order to take advantage of the biogas production from human and animals generated feces in the municipality of Tlalmanalco in the State of Mexico, a theoretical study was carried out in order to verify how feasible it is to implement a system of tubular biodigesters of low cost favoring the community with the lowest resources, as well as reducing the environmental impact of CO2 emissions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
