[Physiological-hygienic aspects of the work of tractor drivers engaged in open-soil vegetable planting]. | LitMetric

The labour conditions of tractor drivers engaged in open soil vegetable planting in subtropical zones were characterized by the unfavourable influence of weather, noise and vibration, dust and exhaust contamination, and by static tension. The physiological studies performed revealed considerable tensions of the CVS, CNS, thermoregulatory and muscle systems in the drivers. The specificity of the identified changes confirmed marked decrease in the functional resources of the organism, which should be taken into account when providing medical services to the drivers.
