Rischio di zoonosi per i lavoratori agricoli lombardi

This work pertains to the study of exposure to air pollution and noise, of any citizen, in any time of day, within the perimeter of the Polyclinic of Bari. We utilized "dynamic" samplings, in a period of 24 hours, along a walking trail that lasted about 70 minutes, divided on the roads inside the general hospital, performed by voluntary people carrying, by shoulder, a bag containing necessary tools, with their sample heads placed externally in the respiratory area. The values of the environmental survey revealed, particularly, the presence of atmospheric concentrations of PMlg of 63,4 pg/mi3 as average value of the whole day and 93 ftg/m3 as maximum average value in one hour, far above the limits expected by law for the protection of human health (maximum average value of 50 figlm3 in 24 hours), almost the whole day and in all areas interested in this study. Also data related to noise showed steady and marked exceeding the limits (average of 68,2 dBA in the morning and 68,0 dBA in the afternoon, versus the limit of SO dBA by day for hospital areas; average of 65,9 dBA in the night, versus the limit of 40 dBA by night for hospital areas). Instead, a normal situation has been ascertained for the remaining pollutants of the study: the concentrations of carbon monoxide (CO), carbon dioxide (C02) and ozone (0}) were consistently maintained below the limits for health protection during the whole survey, as well as monitoring for sulfur dioxide (S02) and volatile organic compounds (VOCs). Air concentration of PMI0 and Leq values for noise were, in different times, above the reference limits and surely prejudicial to human health, not only for casual users, employees and students, but especially for the most sensitive patients accessing the hospital; the highest average values were found in periods corresponding to hours of greater intensity of traffic, or rather in the morning and late afternoon, decreasing, however, during the night. It supports the hypothesis that the main anthropogenic source for pollution should be found in the excessive road traffic and transport, as well as data of other urban areas confirm.
