In the case of Legionella-contaminated water, higher treatment temperature increases the rate of inactivation and the dose of disinfectant can be reduced ( Takacs, 2015 ). Since various species of Legionella have been isolated from untreated drinking water, free chlorine alone may not be sufficient to meet the USEPA standard of 3 CFU/100 mL, especially if water temperatures are high. A study by Suzuki et al. (2010) found that lower temperatures and natural organic matter were associated with slower Legionella growth and reduced biofilm thickness in the total suspended solids (TSS) of a spa. They considered the possibility of a transfer from Legionella to other bacteria as a source of contamination ( Suzuki et al., 2010 ). The authors also found that biofilm mass and thickness were positively correlated with the concentrations of iron and manganese. Metal ions and organisms associated with the corrosion and biofouling of cooling towers and heat exchangers have been shown to potentiate Legionella formation by allowing interspecies spread ( Courtney et al., 2009 ; Plante et al., 2007 ).

Abstract The purpose of this study was to investigate the lung disposition of aerosols generated by a hand-held device used for drug delivery in small animals. Two conventional nebulizers and an ultrasound nebulizer were tested. All aerosols generated by the nebulizers were captured with an efficient capture device (Fibra+) and stored for analysis. In-vitro studies were performed with A549 cells and results are discussed. Ultrasound nebulization device has been marketed; inside mask system (enabled at&the />5th position) shows almost no viable bacteria after 1 h simulated light energy. Plivenbo14
