An evaluation analysis of volatile organic compounds (VOCs) produced by the different laboratories of the Technical University of Ambato was carried out using the Quality Norm for internal environments ISO 171330. Benzene, toluene, and xylene (BTX) were sampled using the Norm of UNE 689 Chemical Risk Assessment, measurement tests were carried out in the Physical-Chemical and Instrumental Analysis, General Chemistry, and Food Research Center laboratories for 90 working days. The BriD MX6 (direct-photoionized measurement) was used for the measurements. The exposure indices in parts per million (ppm) were: Instrumental Analysis: benzene 10.35, toluene 0.12, xylene: meta 0.08, ortho 0.07, para 0.08, General Chemistry: benzene 22.13, toluene 0.13, xylene: meta 0.17, ortho 0.17 and for 0.12; and the Food Research Center: benzene 17.74, toluene 0.14, xylene: meta 0.13, ortho 0.17 and for 0.15; determining a value of the total exposure index in ppm: Instrumental Analysis of 10.54, general chemistry of 22.71 and the Food Research Center 22.76. Exceeding the Recommended Environmental Limit Value (VLA). Finally, an attenuation system was developed calculating a total ventilation flow for each of the laboratories in cubic meters per hour. Laboratories use BTX in different concentrations, this causes its concentrations to vary. Finally, the total evaporation rate calculated in liters per hour was obtained. The parameters required by the Institute for Occupational Safety and Hygiene (INSHT) were used.by the Institute of Occupational Safety and Hygiene (INSHT) were used.

The aerobiological study was made in the Sanitary Landfill of Salcedo’s city, which process consisted of taking the air with sterile syringes of 20 cm3 and injecting it into 10 ml of Brain-heart infusion medium to incubate the microorganisms at 37°C. The objective was study the proliferation of microorganisms within the human organism, this study was carried out in the solid waste disposal area and the hospital waste area, where the presence of pathogenic microorganisms which may be responsible for infections in the worker was evaluated. To determine the biological risk was taken as reference the Royal Decree 664/1997 which establishes the microorganism’s classification according to their infectious capacity. In this research was found a couple of dangerous bacteria such as Escherichia coli and Salmonella typhi, which belong to the third group of this classification, indicating that these microorganisms are capable to produce serious pathologies and are therefore a serious risk to the worker's health and a possibility of spreading into the community. Due to the present risk in the evaluated area, a biosecurity instructive and an instructive about the use of PPE (personal protection equipment) and occupational hygiene were made, which mitigate the risk due to exposure to Salcedo Municipal GAD workers.

The landfill is part of the environment where different pathogen microorganisms take place, it is harmful for the human being because of the household, hospitals and industries garbage, it is dangerous for the landfill workers and the lack of knowledge about the different biohazards result labor negligence that produce diseases and lack of hygiene in the work field. The aerobiological study was done in two unloading areas, common and hospitable garbage, taking into account the variables that affects the microbial growth and the interaction with workers such as: the labor hours and the days of sampling, the result was the identification of harmful microorganisms like Salmonella, Escherichia coli and Klebsiella, between the most common because of the way of working in the landfill of the GIDSA. The identification of the previous germs was possible starting from the characteristics that they have to use different substrata as an only one power source and the production of specific enzymes used for the reduction of compounds in the means of culture employed, using the IMViC biochemical test, the ones that have identified germs according to genre and sort. It is bibliographically proved. Identifying germs and knowing the different characteristics they have, and the diseases that they produce, it was enough to do a security guide for the workers of the landfill, it has different guidelines for each function, helping to improve the security in the work field controlled by the la Empresa Pública Municpal Gestion Integral de Desechos Sólidos Ambato GIDSA. It will be possible if all the elements and suggestions done in the guide are applied correctly.
