Insalubridade habitacional e os seus impactos na saúde respiratória
Luz, Silvana; Calado, Rosa; João Santos, Maria; Silva, RuteA insalubridade habitacional refere-se a condições inadequadas de habitação, que comprometem a saúde e o bem-estar dos indivíduos que nela habitam, bem como dos que os rodeiam. Estas condições podem ter origem estrutural, ambiental ou social, incluindo situações de ventilação deficitária, presença de humidade e bolores, superlotação, saneamento inadequado, poluição do ar interior e exposição a agentes biológico...
Ecotoxicological risk assessment as a decision tool for the valorisation of win...
Luz, Silvana; Catarino, Adriana; Rivas, Javier; Carvalho, Fátima; Palma, Patrícia; Santos, Maria Teresa; Afonso, Alexandra; Regato, MarianaA simple and economical process consisting in the precipitation with slaked lime (Ca(OH)2) was applied to winery wastewater. The process not only removed organic matter and other contaminants but also simultaneously captured atmospheric CO2. In order to help the wine industry to advance to the objective of circular economy, treatment byproducts (supernatant and sludge) have been reused for agricultural purposes...
Reuse of Pretreated Agro-Industrial Wastewaters for Hydroponic Production of Le...
Afonso, Alexandra; Regato, Mariana; Patanita, Mariana; Luz, Silvana; Carvalho, Maria João; Fernandes, Annabel; Lopes, Ana; Almeida, AdelaideThe utilization of agro-industrial wastewaters (AIWWs), pretreated by immediate one-step lime precipitation + natural carbonation, as a nutritive solution for the hydroponic production of lettuce was evaluated. The AIWWs studied were olive mill wastewater (OMW), winery wastewater (WW), and cheese whey wastewater (CWW). Lettuces (Lactuca sativa L. var. crispa) were grown in a closed nutrient film technique hydro...

Luz, Silvana; Rivas, Javier; Afonso, Alexandra; Carvalho, FátimaThe winery wastewater (WW) of the Village of Vidigueira, in south of Portugal, presented an acid pH (4.26 ± 0.029), a high content of chemical oxygen demand (COD = 3236 ± 30.43 mg L-1), turbidity (160.0 ± 7.68 NTU), total P (155.5 ± 6.36 mg L-1) K (100.5 mg L-1), and low level of metals: Pb, Cd, Cu, Ni, Mn, Fe, Zn. The K and the total P content could make them attractive from an agricultural point of view. Howe...
Process of treatment of agroindustrial waste water by reaction of acidification...
Prazeres, Ana; Luz, Silvana; Guerreiro, Raquel; Madeira, Luis; Alves, Eliana; Carvalho, Fátima; Afonso, Alexandra; Almeida, AdelaideThe present Invention relates to a process for the treatment from agroindustrial facilities in particular from slaughterhouses, olive oil process, cheese industries or wine producing facilities by reaction of acidification with the addition of strong acids under agitation conditions and precipitation, according to claim 1. The application of this process to agroindustrial wastewater reduces its level of contami...
Hydroponic system: A promising biotechnology for food production and wastewater...
Prazeres, Ana; Albuquerque, António; Luz, Silvana; Jeronimo, Eliana; Carvalho, FátimaWastewaters contain high loads of organic matter and nutrients, constituting a severe problem. These wastewaters, after the application of an appropriate treatment, can be used for food production, improving its yield and quality. The use of reclaimed water for irrigation has been often recommended by several organizations, namely, the Environmental Protection Agency (EPA), World Health Organization (WHO), and ...

Prazeres, Ana R.; Albuquerque, António; Luz, Silvana; Jerónimo, Eliana; Carvalho, FátimaSeveral regions of the world are suffering from water scarcity and available water pollution. Mediterranean countries (such as Portugal, Spain, Italy, Greece, Tunisia, Israel, and Jordan) do not meet the requirements in terms of quantity that have been increasing in the last decades for the various sectors, due to lack of water resources, winters with low rainfalls, and summers with hot and dry conditions.
