  • Gas Detection in Recreation Facilities: Can the same detector work for pools and arenas?

    It is not uncommon for the same recreational facility to offer both skating and swimming amenities, two very different environments with different potential gas hazards. Given the fact that there is a possibility of 6 different types of gas to monitor and the large area between the two types of facilities, a single detector will not provide the monitoring requirements for both areas. It is ...

  • Application of an optimized system for the well-defined exposure of human lung cells to trichloramine and indoor pool air

    In this study an in vitro exposure test to investigate toxicological effects of the volatile disinfection by-product trichloramine and of real indoor pool air was established. For this purpose a set-up to generate a well-defined, clean gas stream of trichloramine was combined with biotests. Human alveolar epithelial lung cells of the cell line A-549 were exposed in a CULTEX® device with ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...
