To meet mounting water demands, treated wastewater has become an important source of irrigation. Thus, contamination by pharmaceutical compounds (PCs) and the fate these in agricultural environment are increasing concern. This field study aimed to quantify PC uptake wastewater-irrigated root crops (carrots sweet potatoes) grown lysimeters evaluate potential risks. In both crops, nonionic PCs (carbamazepine, caffeine, lamotrigine) were detected at significantly higher concentrations than...
An increasing number of reports on plant uptake pharmaceutical compounds (PCs) have been recently published, raising concerns human exposure through dietary intake. In this study, PC and translocation were evaluated in cucumber tomato plants to elucidate the effects physicochemical properties, soil type, irrigation-water quality. Nonionic PCs taken up accumulated at higher levels grown soils lower organic matter clay content. While concentration most leaves similar order, their...
The siderophore rhizoferrin, produced by the fungus Rhizopus arrhizus, was previously found to be as an efficient Fe source Fe-ethylenediamine-di(o-hydroxphenylacetic acid) strategy I plants. role of this microbial in uptake II plants is focus research. Fe-rhizoferrin for barley (Hordeum vulgare L.) and corn (Zea mays L.). mechanisms which these Gramineae utilize from other chelators were studied. 59Fe-rhizoferrin, 59Fe-ferrioxamine B, 59Fe-ethylenediaminetetraacetic acid,...
Summary Phosphorus loss from land can be a major factor affecting surface water quality. We studied P‐release mechanisms in wetland soils that had been drained and cultivated for four decades then re‐flooded. measured redox, pH solution composition two sites the field peat calcareous incubated biogeochemical microcosms. The redox measurements during 120 days of incubation resulting soil indicated main process leading to P release is reductive dissolution ferric hydroxides on which was...
It has been known for 160 years that iron is essential plant growth. Its deficiency occurs especially, but not only, in calcareous soils and it limits crop production large parts (> 30%) of the Earth's arable land. The mineralogy geochemistry Fe soils, as well functions within plants, soil factors limit its availability, mechanisms acquisition from are all fairly documented. Yet, alleviation Fechlorosis especially lime-induced chlorosis remains a major agronomic problem. Three main...
Root and microbial respiration is considered to be the main source of CO 2 production in soil; however, calcite dissolution calcareous soils may contribute emitted . The major aim this research was quantify contribution CaCO 3 emission from a soil with without addition an organic residue. Emissions its δ 13 C incubated noncalcareous (Golan Heights [GH], −26.23‰) (Bet She'an [BS], −11.47‰) pasteurized chicken manure (PCM, −23.2‰) were determined. During 56 d incubation, 445 1804 mg kg −1 –C...
ABSTRACT A constant anthropogenic release of cadmium to the environment has resulted in a continuous buildup Cd soils. Uptake and accumulation plant tissue grains may lead food chain transfer humans. Application synthetic chelates was suggested increase metal mobilization facilitate phytoextraction as means for remediation metal‐polluted However, most chelate‐extracted be leached rather than mobilized roots. In contrast added soils, plant‐produced chelators called phytosiderophores (PS) are...
Abstract Rhizonus arrhizus was found to produce a novel siderophore named raphorin (Ra) when grown under Fe deficiency. Partially purified Fe‐Ra alleviate deficiency applied tomato plants in nutrient solutions buffered by either CaCO3 (pH 7.3) or HEPES 7). Iron (55Fe) uptake rate mediated Ra, and translocation the shoot, almost as high from 55FeEDDHA. It has been concluded is most efficient source for compared other microbial sidero‐phores.
Carbamazepine and lamotrigine prescribed antiepileptic drugs are highly persistent in the environment were detected crops irrigated with reclaimed wastewater. This study reports pharmacokinetics of two their metabolites cucumber plants under hydroponic culture, testing uptake, translocation, transformation over 96 h single bisolute systems at varying pH. Ruling out root adsorption transformations nutrient solution, we demonstrate that carbamazepine uptake is largely affected by concentration...
Abstract Although microbial siderophores are characterized by high affinity and selectivity for Fe3+, they usually less efficient as Fe‐carriers to plants than synthetic chelates. An exception this is rhizoferrin, a fungal siderophore produced Rhizopus arrhizus isolated purified our group. A ferric complex of rhizoferrin was used in study an Fe source tomato cucumber ("strategy I") barley corn II") grown nutrient solutions. The Fe‐rhizoferrin found be carrier these plants. efficiency chelate...
ABSTRACT Three chemicals, ferrous sulfate (Fe‐sul), calcium oxide (CaO), and aluminum (alum), were used to stabilize phosphorus (P) in fresh, anaerobically digested sewage sludge (FSS). The chemically stabilized materials biosolids compost (BSC) compared with the FSS respect water‐soluble (WSP) content its inorganic (WSP i ) organic o forms as well carbon (DOC). Solid‐state P speciation was further probed by X‐ray diffraction (XRD) scanning electron microscopy (SEM) equipped...
We studied the adsorption characteristics of P in altered peat soils Hula Valley, Israel, which has undergone repeated drying and rewetting cycles. As a result, water quality Lake Kinneret, only freshwater lake may have been adversely affected. Peat sample collection was based on pedogenic evaluation wetland's history redox potential aerobic (Eh = 450 mV) anaerobic < −220 conditions. Extractable citrate–bicarbonate–dithionite iron (Fe CBD ) dominant mineral phase layers (29 ± 5 g kg −1 )....
Three chemicals-ferrous sulfate (FeSul), calcium oxide (CaO), and aluminum (alum)-were applied at different rates to stabilize P in fresh, anaerobically digested biosolids (FBS) obtained from an activated sewage treatment plant. A modified Hedley fractionation procedure was used assess forms these sludge-borne materials a compost (BSC) prepared the same FBS. Each material exhibited unique pattern of distribution among fractions. The most available forms, namely: (i) water-soluble (WSP); (ii)...
