Disinfection by-products of emerging concern in drinking water : monitoring and...
Chaves, Raquel S.The access to safe drinking-water is essential to assure health. It is a basic human right and a component of effective policy for health protection. Due to the increase levels of environmental pollution in some systems, it is crucial to assess water quality applying an integrative approach, combining environmental and human risk assessments, attending to surface sources pressure and the consequent drinking wat...
Using zebrafish embryo bioassays combined with high-resolution mass spectrometr...
Wilson, Estibali Wilkie; Castro, Verónica; Chaves, Raquel S.; Espinosa, Miguel; Rodil, Rosario; Quintana, José Benito; Vieira, Maria NatividadeSeveral studies show that many water bodies in developing countries are increasingly affected by anthropogenic pressure, such as agricultural activities, domestic and industrial wastewater. However, data is scarce in several of such countries, including Panama. Thus, in this work, the ecotoxicological status of selected rivers in Panama with distinct input sources were evaluated using the zebrafish (Danio rerio...
Assessment of water quality parameters and their seasonal behaviour in a Portug...
Chaves, Raquel S.; Salvador, Daniel; Nogueira, Paulo Jorge; Santos, Miguel M.; Aprisco, Paula; Neto, Célia; Cardoso, Vítor; Benoliel, Maria J.Water quality monitoring is a fundamental tool in the management of freshwater resources. The purpose of monitoring is to provide meaningful quality data for local action planning and catchment-wide decision making. The assessment of water quality is crucial to guarantee the efficient operation of the Water Treatment Plants (WTPs), promoting health conditions and contributing for a more sustainable urban water ...
Toxicological assessment of seven unregulated drinking water Disinfection By-pr...
Chaves, Raquel S.; Guerreiro, Catarina Sousa; Cardoso, Vítor V.; Benoliel, Maria J.; Santos, Miguel M.Disinfection By-products (DBPs) are formed during the chemical treatment of water for human consumption, by the reaction of raw water with chemical agents used in the different steps of the process. Disinfection is one of the most important steps, inactivating pathogens and preventing their regrowth during water distribution. However, it is also involved in DBPs formation due to the use of disinfectant agents, ...
Hazard and mode of action of disinfection by-products (DBPs) in water for human...
Chaves, Raquel S.; Guerreiro, Catarina Sousa; Cardoso, Vítor V.; Benoliel, Maria J.; Santos, Miguel M.Disinfection of water system is an essential strategy to protect human health from pathogens and prevent their regrowth during water distribution, but the reaction of disinfectant agents with organic matter can lead to the formation of disinfection by-products (DBPs). Given their widespread occurrence, potential human health impacts and (eco)toxicity associated with exposure to DBPs are of particular interest d...
