Abstract:
... The gastronomical use of wild and native foods has gained the attention of chefs around the world in the search for new flavors. To make use of such foods also helps in the preservation of local and native flora. Native plants should be reconsidered throughout their value chain, linking their socio-cultural importance, their health benefits and their economic advantages to local communities. Brazi ...

Abstract:
... In anoxic environmental conditions and with a drastic reduction of the redox potential, the barium sulphate used in petroleum drilling fluids becomes a hazard to the ecosystem. A field study was conducted in Brazil in an area with a history of accidental Barium (Ba) contamination to evaluate the role of frequent plant cutting on phytoremediation. The plant species Typha domingensis and Eleocharis ...
