Environmental Risk Assessment of Glyphosate and Aminomethylphosphonic Acid (AMP...

The aim of the present study was to assess the risk related to the exposure of groundwater ecosystems to herbicide glyphosate and its non-relevant metabolite aminomethylphosphonic acid (AMPA) based on the quotient between measured concentrations gathered from the Water Resources Information System of Portugal, and groundwater quality standards set in legislation and estimated from environmental quality standard...

Chemical and ecotoxicological assessment of agricultural drainage water from a ...

The use of agricultural drainage water (ADW) in irrigation is a great challenge, improving water use efficiency, nutrient circularity, and avoiding surface and ground-water contamination. The objective of this study was to evaluate the chemical and ecotoxicological characteristics of an ADW to analyze the safety of its reuse. An irrigated area with maize crops was selected (Tejo Basin, Portugal), where a subsur...

Unravelling relationships between in vivo effects on plants and detected pestic...

The multiple benefits agriculture provides to society depend on the long-term sustainable management of water resources, including the preservation of a good ecological and good chemical status of the water bodies. Presently, this good chemical status has not been reached in the majority of European river basins. Implemented monitoring strategies are targeted to identify the presence and magnitude of the ecolog...

Death Threats and Attempted Femicide in the Context of Domestic Violence in Por...

Domestic violence is a serious problem in Portugal, affecting mainly women. The significant number of femicides in the context of intimate partner violence has been showing not only the severity of the crime, but also the necessity to reinforce strategies to prevent and combat it. Although several studies were developed in the last decades to portray domestic violence, research on the threat of death and attemp...

Vulnerabilidade, monitorização e risco de contaminação por nitratos na zona vul...

Em virtude das características hidrogeológicas e da ocupação agrícola intensiva, no dia 3 de Setembro de 2004, através da Portaria 1100/2004, o sector norte da zona aluvionar do Tejo foi designado zona vulnerável à poluição difusa de nitratos de origem agrícola (ZVT). Esta região abrangendo os concelhos da Golegã, Alpiarça, Santarém, Chamusca, Vila Nova da Barquinha, Constância e Torres Novas tem uma área aprox...

Avaliação do risco de pesticidas individuais e suas misturas em águas de superf...

Este estudo pretendeu avaliar o risco dos pesticidas e das suas misturas em águas de superfície de áreas agrícolas do concelho da Golegã. De 12 pesticidas analisados por SPME/GC-MS, foram detetadas as substâncias prioritárias alacloro, atrazina, clorfenvinfos, clorpirifos e outros poluentes (3,4-DCA, etofumesato, metolacloro e terbutilazina). O alacloro e o clorpirifos foram determinados com concentrações super...
