Influence of Wearing Ballistic Vests on Physical Performance of Danish Police Officers: A Cross-Over Study.

Purpose: We aimed to investigate the influence of wearing a ballistic vest on physical performance in police officers.

Methods: We performed a cross-over study to investigate the influence of wearing a ballistic vest on reaction and response time, lumbar muscle endurance and police vehicle entry and exit times. Reaction and response time was based on a perturbation setup where the officers' pelvises were fixed and EMG of lumbar and abdominal muscles was recorded.

Towards a risk evaluation of workers' exposure to handborne and airborne microbial species as exemplified with waste collection workers.

Bioaerosol exposure is associated with health problems. The aim of this study is to evaluate whether it is possible to assess the risks posed by waste collection workers' exposure through identification and characterization of bacterial and fungal species, to which the workers are exposed. Using MALDI-TOF MS, microorganisms in waste collection workers' exposure through air, hand, and contact with the steering wheel were identified.
