Green organizational climate’s promotion of managers’ organizational citizenshi...

Society at large has become increasingly concerned about climate change and sustainable development, so tourism and travel service providers have begun to focus more actively on sustainable development goals. Prior research has shown that supervisors’ support fosters employee green behavior and companies’ environmental performance. This study concentrated on Portuguese hospitality contexts to develop a fuller u...

Mercury and Blood Pressure Levels in Inhabitants from a Highly Industrialized R...

Estarreja is a highly industrialized municipality in NW Portugal, well known for its historical mercury contamination. Some reports have linked hypertension and mercury exposure. In this work, we collected house dust samples and hair from the residents of this area, together with systolic (SBP) and diastolic (DBP) blood pressure. Hair mercury levels varied between 624 and 4535 ng/g, and mercury in dust varied f...

Rheologic effect of selected acrylamide reducing agents from plant extracts in ...

Bread is a staple food worldwide with an annual intake recommended by the WHO of 60kg / capita. Strategies to mitigate the occurrence of substances harmful to human health such as acrylamide (AA) should not interfere in food properties perceived by the consumers. The objective of this work was to assess the rheologic (texture and color) effect on two types of bread formulas (wheat and rye) that the addition of ...

Main goal: To provide a global picture on the prevalence of chronic respiratory diseases in Estarreja and to characterize, for the 1st time, the indoor microbiome (fungi and bacteria).

Impact of sampling depth and plant species on local environmental conditions, m...

We compare the environmental characteristics and bacterial communities associated with two rushes, Juncus maritimus and Bolboschoenus maritimus , and adjacent unvegetated habitat in a salt marsh subjected to historical mercury pollution. Mercury content was higher in vegetated than unvegetated habitat and increased with sampling depth. There was also a significant relationship between mercury concentration and ...

New molecular variants of epsilon and beta IncP-1 plasmids are present in estua...

In this work the presence of broad-host-plasmids in an estuary in Portugal has been inves- tigated. Pseudomonas putida KT2442 was used as model recipient bacteria in biparental matings with tetracycline and mercury to select for resistance phenotypes. As a result, 7 transconjugants were shown to carry broad-host-plasmids from the IncP-1 group, as seen by PCR amplification of the trfA gene. Sequence analysis con...

Effects of UV-B radiation on the structural and physiological diversity of bact...

The effects of UV radiation (UVR) on estuarine bacterioneuston and bacterioplankton were assessed in microcosm experiments. Bacterial abundance and DNA synthesis were more affected in bacterioplankton. Protein synthesis was more inhibited in bacterioneuston. Community analysis indicated that UVR has the potential to select resistant bacteria (e.g., Gammaproteobacteria), particularly abundant in bacterioneuston.

Bacterial diversity and geochemical profiles in sediments from eutrophic Azorea...

In the Azores, the advanced trophic state of the lakes requires a fast intervention to achieve the good ecological status prescribed by the Water Framework Directive. Despite the considerable effort made to describe the phytoplankton growing on the water column, the lack of information regarding the microbial processes in sediments is still high. Thus, for the successful implementation of internal management ac...
