THE ENVIRONMENTAL IMPACT OF USING COPPER SULPHATE TO AVOID GRAPEVINE POWDERY MI...
Patinha, Carla; Reis, Amélia; Dias, Ana; Cachada, Anabela; Pato, Pedro; Ferreira da Silva, Eduardo; Fonseca, Rita; Barriga, Fernando; Janeiro, AnaCopper-based fungicides have been used in vineyards throughout the world, for many decades to protect against downy mildew. However, their use results in an accumulation of Cu in surface soils which can potentially impact on the biological health of the soil and could be transported and stored in the sediments deposited close to valley bottoms. In Douro region, northern of Portugal, vineyards are located on ste...
GRAPEVINE CULTIVATION AND THE GEOCHEMISTRY OF ZINC: IMPACT ON THE ENVIRONMENTAL...
Reis, Amélia; Patinha, Carla; Dias, Ana; Cachada, Anabela; Pato, Pedro; Ferreira da Silva, Eduardo; Fonseca, Rita; Barriga, Fernando; Janeiro, AnaThis study presents preliminary results of a research project that aims assessing the environmental impact of intensive grapevine cultivation in the Alto Douro wine region, a World Heritage Site. A total of 50 soil samples were collected from three nearby vineyards of different ages. Surface drainage of these vineyards discharges into an important water reservoir, the Varosa Dam. The dam collects water from two...
Organochlorine contaminants in different tissues from Platichthys flesus (Pisce...
Batista, Joana; Pato, Pedro; Duarte, Armando C.; Pardal, M. A.Polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) are organic contaminants that tend to accumulate in fish. Estuaries are exposed to high anthropogenic activities, therefore tending to accumulate more contaminants than the adjacent coastal waters. Platichthys flesus, a fish with high economic value, was analysed for PCBs and HCB along its different age groups, in liver, gills, gonads and muscle. Youn...

Influence of sex and age on PCBs accumulation in the commercial fish Chelon lab...
Baptista, Joana; Pato, Pedro; Tavares, Sílvia; Duarte, Armando C.; Pardal, Miguel A.Thicklip grey mullet, Chelon labrosus, is an important commercial fish species and has been studied worldwide. However, no recent studies have been made regarding polychlorinated biphenyls (PCBs) in wild C. labrosus. Due to that, the concentration of 13 PCBs congeners was measured in muscles and livers, of males and females, of C. labrosus of different ages, allowing the estimation of PCB bioaccumulation throug...
