Vegetated filter strips for wastewater purification: A review

Glutathione S-transferases in Festuca arundinacea: Identification, characterization and inducibility by safener benoxacor

“…A recent study shows that the perennial grass, Festuca arundinacea, possesses a consistent GST detoxifying activity toward some synthetic compounds (Scarponi and Del Buono, 2005). These behaviours potentially make Festuca an interesting plant to vegetate buffer strips, which are zones left along the boundaries of crops to reduce the contamination of surface runoff by various pollutants, herbicides included (Delgado et al, 1995;Patty et al, 1997;Vianello et al, 2004).…”

Water purification using magnetic assistance: A review

“…In the area of biotechnology, plants as sorbents and microbes for contaminant destruction or transformation are widely studied [14,15]. In case of water purification for degradation of organic pollutants, Simpson gave an account on biologically active carbon biofilm capable of degrading a significant fraction of entrapped water-borne nutrients and dissolved organic matter adsorbed on granular activated carbon (GAC) surfaces and other contaminants, minerals and microorganisms contained in source water [16].…”

El conflicto de uso del suelo y la calidad de los alimentos The soil use conflict and food quality

“…Para ello, una medida muy importante es mantener bandas de proteccio´n alrededor de los terrenos cultivados que atenu´en la escorrentı´a agrı´cola. Esta es la manera ma´s efectiva de disminucio´n de la carga de contaminacio´n no puntual (Delgado, Lo´pez Periago, & Dı´az-Fierros Viqueira, 1995), no solamente para sistemas acua´ticos continentales sino que tambie´n para el litoral. En el caso de Espan˜a, el Real Decreto Legislativo 1/2001, del 20 de julio, por el que se aprueba el texto refundido de la Ley de Aguas, su artı´culo 6 establece una servidumbre de cinco metros de proteccio´n y una zona de 100 m de vigilancia.…”
