Solar light efficient photocatalytic activity degradation of emergent contaminants by coated TiO2 nanoparticles
(Royal Society of Chemistry, 2018-08-09)
The photocatalytic degradation of different emergent contaminants in aqueous solutions has been studied by using oligomer-coated TiO2 nanoparticles under solar light irradiation. The oligomer was synthesized using methacrylic ...
Lead pollution from hunting ammunition in Argentina and current state of lead shot replacement efforts
(Royal Swedish Acad Sciences, 2019-04)
Waterfowl hunting in Argentina is a profitable industry that attracts hunters from all over the world. Most hunting occurs as high-end hunting tourism, through which registered outfitters service predominantly foreign ...
TiO2-rGO photocatalytic degradation of an emerging pollutant: Kinetic modelling and determination of intrinsic kinetic parameters
(Elsevier Ltd, 2019-10)
An intrinsic kinetic model, derived from a suggested reaction photo-mechanism and with an explicit dependence on the local volumetric rate of photon absorption (LVRPA), was developed to simulate the photocatalytic degradation ...
Inter‐and intra-stock bioaccumulation of anionic arsenic species in an endangered catfish from South American estuaries: risk assessment through consumption
(Academic Press Inc Elsevier Science, 2020-04)
Monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), inorganic arsenic (iAs), and non-toxic species (i.e. arsenobetaine) were determined by HPLC-ICP-MS as mg kg−1 wet weight in muscle, liver and gill of catfish (Genidens ...
Selection of sustainable projects for floodplain restoration and urban wastewater management at the lower Chubut River valley (Argentina)
(Elsevier Science, 2008-04)
Urban growth causes environmental degradation of extended areas at the coastal floodplain of the Chubut River (Argentina). We developed procedures to identify environmentally sustainable engineering projects for floodplain ...
Modulation of cutaneous scavenger receptor B1 levels by exogenous stressors impairs “in vitro” wound closure
(Elsevier Ireland, 2017-11)
Scavenger receptor B1 (SR-B1) is a trans-membrane protein, involved in tissue reverse cholesterol transport. Several studies have demonstrated that SR-B1 is also implicated in other physiological processes, such as bacteria ...
The impact of point source pollution on shallow groundwater used for human consumption in a threshold country
(Royal Society of Chemistry, 2012-06)
Many developing and threshold countries rely on shallow groundwater wells for their water supply whilst pit latrines are used for sanitation. We employed a unified strategy involving satellite images and environmental ...
A review of lead contamination in South American birds: The need for more research and policy changes
(Associação Brasileira de Ciência Ecológica e Conservação, 2018-10)
Lead contamination is a worldwide problem that affects the health of several bird species and can cause biodiversity loss. However, in South America there is little information about this problem and the species affected. ...
Assessment of the root system of Brassica juncea (L.) czern. and Bidens pilosa L. exposed to lead polluted soils using rhizobox systems
(Taylor & Francis, 2016-03)
The purpose of this study was to compare the behavior of the root system of one of the most frequently cited species in phytoremediation Indian mustard [Brassica juncea (L.) Czern.] and a representative perennial herb ...
Satellite-based view of the aerosol spatial and temporal variability in the Córdoba region (Argentina) using over ten years of high-resolution data
(Elsevier Science, 2018-11)
Space-based observations offer a unique opportunity to investigate the atmosphere and its changes over decadal time scales, particularly in regions lacking in situ and/or ground based observations. In this study, we ...
