Abstract
Aim: To describe the socio-environmental situation in the vicinity of the Tecámac landfill and the health risk associated with leachates and microbiological air transport.
Methodology: An exploratory study was carried out from a visit to the sanitary landfill through direct observation, interviews with sanitary workers and people affected by living in the immediacy of the landfill. Samples of leachate and soil these were analyzed in the laboratory, firstly to achieve the recoverability in Agar Soy Tripticase [AST] and proceeded to their identification by biochemical tests.
Results: Among the chemical products perceived when visiting this socio-environmental context is hydrogen sulfide, which impacts the nervous system at the level of neurobiological vitality. The acute-chronic exposure in the population adjacent to the landfill and its leachates is enough to insist that environmental control of this area be warranted. Among the bacteria detected, 60% were Gram-positive bacilli and 30% were Gram-negative bacilli. Bacteria present in this environment are: Bacillus cereus, Bacillus subtillis, Bacillus sp and Pseudomonas aeuroginosa, P. putida, Klebsiella pneumoniae, Escherichia coli and Enterobacter cloacae. Conversation with people denotes exposure to chemicals-microorganisms and risks to human health.
Conclusion: The presence of microorganisms and virulence profile are aspects to be considered in these bacteria is their virulence profile, and their biotechnological profile when they present an effect as generators of plant growth. For this reason, the study of this type of bacteria is transcendent in the fields of Environmental Sciences and Public Health.
