Pesticide water variability and prioritization: The first steps towards improvi...
Alves-Ferreira, Júnia; García Vara, Manuel; Catarino, Adriana; Martins, Inês; Mourinha, Clarisse; Fabião, Marta; Costa, Maria JoãoThe presence of pesticides in aquatic ecosystems poses significant risks to non-target organisms, necessitating monitoring and environmental risk assessment. This study aimed to evaluate the dynamics and environmental risk of pesticides in a hydro-agricultural area with intensive agricultural practices, in the Mediterranean region (South of Portugal). Seasonality and location influenced pesticide numbers and co...
Cistus ladanifer as a potential feedstock for biorefineries: A review
Alves-Ferreira, Júnia; Duarte, Luís C.; Fernandes, Maria C.; Pereira, Helena; Carvalheiro, FlorbelaCistus ladanifer (rockrose) is a widespread shrub species in the Mediterranean region well known due to its production of labdanum gum, especially in the hot season. Its leaves and branches can be subjected to different extraction and distillation processes to produce various types of extracts. The natural extracts of C. ladanifer have several applications, especially in the perfumery and cosmetics sector. C. l...

Bioethanol production from globe artichoke residues: From the field to the ferm...
Pesce, Roberto; Alves-Ferreira, Júnia; Hslao, Alice; Martinez, Alfredo; Mauromicale, G.; Fernandes, Maria da Conceição; Torrado, IvoneThe suitability of globe artichoke crop residues to be transformed into bioethanol was assessed in this paper from the field to the fermenter. A 2-year field trial on “Opera F1” (OF1), a hybrid variety of globe artichoke, resulted in an average annual production of residues of 14 t/ha. The residual biomass of OF1 is made up of 24% glucan and 17% hemicelluloses and is rich in soluble sugars. Water extraction (WE...
Delignification of Cistus ladanifer biomass by organosolv and alkali processes
Alves-Ferreira, Júnia; Lourenço, Ana; Morgado, Francisca; Duarte, Luís C.; Roseiro, Luísa B.; Fernandes, Maria C.; Pereira, HelenaResidues of Cistus ladanifer obtained after commercial steam distillation for essential oil production were evaluated to produce cellulose enriched solids and added-value lignin-derived compounds. The delignification of extracted (CLRext) and extracted and hydrothermally pretreated biomass (CLRtreat) was studied using two organosolv processes, ethanol/water mixtures (EO), and alkali-catalyzed glycerol (AGO), an...
