Seeds of four native species trees and shrubs (Larrea cuneifolia, Bulnesia retama, Plectrocarpa tetracantha Prosopis flexuosa) were exposed to soil contaminated with As, Cu, Cd, Zn from an abandoned gold mine identify adaptation strategies. Several physiological, morpho-anatomical, biochemical parameters determined. The seed germination L. B. P. was fully inhibited in 100 % soil. Toxicological endpoints as NOEC, LOEC IC50 ranged 10 25 mining waste. Radicle elongation the most sensitive...

Globally, forest landscape restoration (FLR) is gaining ground, alongside other forms of under the UN Decade on Ecosystem Restoration. In most cases, projects and initiatives fail to consider human dimensions that influence processes outcomes effort. These refer how why humans value natural resources; want resources be managed; affect or are affected by resource management decisions. Using model transition curve shows trajectory from loss forests restored forests, we discuss FLR intersects...

An automated procedure for total and inorganic mercury determination in biodiesel by CV-AFS was studied. The samples were introduced directly as oil-in-water emulsions a flow injection manifold followed cold vapor generation coupled to atomic fluorescence spectrometry (FI-CV-AFS). After irradiation with an UV source, organic (e.g.MeHg+ PhHg+ among others) decomposed. Mercury vapors generated using acidic SnCl2 solution continuous system then determined. This strategy reduced sample handling,...

Foliar fertilization with selenium (Se) may well be beneficial in increasing the nutritional and qualitative values of food Se-deficient regions such as Mediterranean Basin, contribute to an increase drought resistance plants. The present study has considered detachment force, flesh firmness, pigmentation, fresh dry weight, oil content olive drupes from Se fertilized orchards (Olea europaea L.) under stress well-watered conditions. This also evaluated total Se, amino acid, phenol, carotenoid...

Sample preparation involves a critical step due to the high organic matter content that implies its decomposition, prior analysis. Two alternative analytical strategies for sample employing diluted HNO3 were optimized and compared, assisted by ultrasound (USAE) infrared (IRAE) radiation. Multielement determination was achieved MIP OES. For optimization of experimental conditions, central composite design centered on faces carried out, considering four five factors IRAE USAE, respectively....

Mining activity has degraded large extensions of soil and its waste is composed metals, anthropogenic chemicals, sterile rocks. The use native species in the recovery polluted soils improves conditions for emergence other species, tending to a process ecosystem restoration. objective this study was evaluate bioaccumulation metal(loid)s four plants effect their distribution bioavailability with from an abandoned gold mine. Soil samples were taken two sites La Planta, San Juan, Argentina: Site...
