Extensive Exposure to Tear Gases in Ankara

Abstract

OBJECTIVES: The most common chemical substances used as mass control agents are chloroacetophenone, chlorobenzylidene malononitrile, and oleoresin capsicum. These agents not only have local and rapid effects but also have systemic and long-term effects. The aim of the present study was to discuss the patterns of tear gas exposure and to investigate its effects on respiratory functions.

MATERIALS AND METHODS: A face-to-face survey was conducted in 86 individuals who had been exposed to tear gas indoor and outdoor during the public protests in June 2013.

RESULTS: The most frequently reported respiratory complaints included cough, dyspnea, phlegm, and chest pain. Spirometry measurements including forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were also performed. Indoor exposers have lower mean % predicted FVC and FEV1 values than outdoor exposers. All complaints and signs were more common in indoor exposure to tear gas than in outdoor exposure.

CONCLUSION: Safety of the chemicals used as mass control agents during protests is doubtful as these agents are associated with several health risks.
