Abstract
ABSTRACT The effects on human beings of tear gas (CS) used by police forces during the control of civil disturbances are widely known and amply described in numerous scientific papers. However, the advent of the concepts of animal welfare raises the question of whether animals exposed to CS in such events, specifically horses, would suffer the same effects as those described for humans. The purpose of this study was to determine whether mounted police horses exposed to CS exhibit the same symptoms as humans. In this study, 12 horses of the Military Police of Paraná, healthy and with no history of respiratory tract disorders, were led through a gas cloud caused by the detonation of six teargas grenades. The horses’ physiological parameters of respiratory rate, heart rate, rectal temperature, and color of the eye mucosa were evaluated 24 hours before exposure, 30 min, and 24 hours after exposure. Blood samples were collected for complete blood count (CBC) and blood gas analysis and samples of eye mucosa were obtained using sterile swabs. The analysis of these parameters did not reveal effects analogous to those described in humans.
