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...
Production of drinking water using a multi-barrier approach integrating nanofil...
Lopes, Mafalda T. P.; Matos, Cristina T.; Pereira, Vanessa J.; Benoliel, Maria J.; Valério, Maria Ermelinda; Bucha, Luís B.; Rodrigues, AlexandreA multi-barrier system was studied for the production of drinking water with high chemical and microbiological quality. The integration of nanofiltration (NF) and ultraviolet (UV) photolysis was tested at pilot scale in a surface water treatment plant. The NF membranes tested, Desal DK and NF270, allow for the production of permeates with high quality standards, although the membrane with higher molecular weigh...
Distribution of Cryptosporidium species and subtypes in water samples in Portug...
Alves, Margarida; Ribeiro, Ana M.; Neto, Célia; Ferreira, Elisabete; Benoliel, Maria J.; Antunes, Francisco; Matos, OlgaCryptosporidium is a significant cause of diarrhoeal disease in the general population and a major cause for morbidity and mortality in immunocompromised persons. Cryptosporidiosis is a major public health concern and the role of water in disease transmission is now well recognized. The ingestion of oocyst-contaminated drinking water has led to large outbreaks of disease, mostly in North America, the United Kin...
