Cleaning and disinfection: toxicological risk

Abstract

The use of biocides for the surfaces disinfection, as cooling towers, has ended up being a key element for the prevention of illnesses, like it is the case of legionelosis disease. But their use bears to assume risks, as much for the Public and Environmental Health where the discharges can cause deep alterations in the aquatic ecosystems. The analysis apply in this work, about the different parameters for the risk evaluation that supposes the use of these formulated, takes to the conclusion that, still understanding that all biocide could cause adverse effects on organisms and environments, a correct balance among effectiveness and security approaches is the only viable rule to prevent the toxicological risk generated by the necessary cleaning and disinfection rules of these surfaces.
