SummaryThis study aimed (i) to assess the environmental problems of wheat farming in Oxisol with Cd and Pb below the acceptable levels established by national and international regulations, questioning their possible permissiveness; (ii) to investigate the metal distribution in wheat plant organs, and to predict possible implications of cultivation in hazardous conditions; (iii) to assess the grain and flour content of metals and to predict possible implications. The growth of plants, gas exchange parameters, nutritional composition, the yield of grains and metal distribution were evaluated. Cd and Pb are accumulated in different plant organs even when the legislation's limits are respected. 74% of Cd and 96% of Pb are accumulated in roots, while 3% of Cd and <1% of Pb are accumulated in grains. Cd and Pb caused nutritional disorders such as decreased foliar K, Ca, Cu, Zn, Fe and Mn, decreased canopy height, number of tillers, number of spikes, the volume of roots, aerial dry mass and yield of grains. Even if the established limits of Cd are respected, the flour will overtake the provisional tolerable monthly intake established by World Health Organisation. In the evaluated conditions, wheat cultivation in Oxisol within the national standard for Cd could result in hazardous levels in flour.

“…Conversely, the Gd or Tb positive anomalies are basically unexpected in the mineral world, confirming that except for Ce and Eu, which can occur either as tetra-or divalent configurations in addition to their usual trivalent configuration, all other REEs of mineral origin never yield such significant positive anomalies relative to the conventional standards (e.g., Taylor and McLennan, 1985). A straight interpretation for these abnormal Gd and/or Tb supplies might then relate to the occurrence of organic matter as Gd anomalies, at least, were reported in living plants at surficial conditions (e.g., Semhi et al, 2014).…”

International audienceLower- to Middle-Triassic sandstones from eastern Paris Basin were buried to a maximum depth of 2500 m at a paleo-temperature of about 100 °C. They contain extensive amounts of authigenic platy and filamentous illite particles similar to those reported in reservoirs generally buried at 3000 to 5000 m and subjected to temperatures of 120 to 150 °C. To evaluate this unexpected occurrence, such sandstones were collected from drill cores between 1825 and 2000 m depth, and nanometric-sized sub-fractions were separated. The illite crystals were identified by XRD, observed by SEM and TEM, analyzed for their major, trace, rare-earth elements and oxygen isotope compositions, and dated by K-Ar and Rb-Sr.Illite particles display varied growth features in the rock pore space and on authigenic quartz and adularia that they postdate. TEM-EDS crystal-chemical in situ data show that the illite lath/fiber and platelet morphologies correspond at least to two populations with varied interlayer charges: between 0.7 and 0.9 in the former and between 0.8 and 1.0 in the latter, the Fe/Fe+Mg ratio being higher in the platelets. Except for the deeper conglomerate, the PAAS-normalized REE patterns of the illite crystals are bell-shaped, enriched in middle REEs. Ca-carbonates and Ca-phosphates were detected together with illite in the separates. These soluble components yield 87Sr/86Sr ratios that are not strictly in chemical equilibrium with the illite crystals, suggesting successive fluids flows with different chemical compositions. The K-Ar data of finer <0.05 μm illite separates confirm two crystallization events at 179.4 ± 4.5 and 149.4 ± 2.5 Ma during the Early and Late Jurassic. The slightly coarser fractions contain also earlier crystallized or detrital K-bearing minerals characterized by lower δ18O values. The δ18O of the finest authigenic illite separates tends to decrease slightly with depth, from 18.2 (± 0.2) to 16.3 (± 0.2) ‰, suggesting different but contemporaneous crystallization conditions deeper in the section.The illite platelets and filaments crystallized in changing physical-chemical crystallization conditions induced by fluids flows through the host-rock pore system. These flow events were probably driven by repetitive rifting episodes of the North Atlantic Ocean, although located several hundreds kilometers away from eastern Paris Basin, and/or by fracturing events in the nearby basement of the Vosges Massif. Complex relationships between geodynamical events, thermal anomalies, and advective fluids confirm that remote tectonic activities can impact quiescent basins, even if located far from tectono-thermal activities, by discrete and long-distance fluid flows

“…Therefore, it is imperative to find a potential radish cultivar with a low accumulation of Cd and Pb for safe consumption and to study Cd and Pb tolerance mechanisms to increase the production of safe radishes. A previous study investigated the characteristics of Cd and Pb accumulation under two different concentrations of Cd and Pb in one radish cultivar (Semhi et al, 2014). However, to our knowledge, there are no published reports focusing on Cd and Pb accumulation and its toxic effects on growth and metabolism in various radish cultivars.…”

Cadmium (Cd) and lead (Pb) are toxic even in small quantities and decrease crop yields. They are easily absorbed by plant roots, and thus enter the food chain, risking human health. Radish (Raphanus sativus L.) is a widely consumed root vegetable in Korea. Therefore, it is important to screen for a radish cultivar that exhibits low Cd and Pb accumulation and elucidate the Cd and Pb tolerance mechanism. In this study, we determined the effect of Cd and Pb stress on germination and growth in four radish cultivars, 'Gaulgeojang' (AG), 'Iseogaul' (IG), 'Chongryong'(CR), and 'Supertogwang' (ST). Furthermore, Cd and Pb concentrations, production of nonprotein thiols (NPTs), and hydrogen peroxide (H 2 O 2 ) levels were investigated in four cultivars of radish seedlings under Cd and Pb treatments. The cultivars showed tolerance to Cd and Pb stress during germination and seedling growth in the following order: CR > ST > IG > AG. CR, a tolerant cultivar, accumulated less Cd in roots and less Pb in both roots and shoots than the other cultivars. In contrast, AG, a sensitive cultivar, exhibited greater Cd and Pb accumulation in roots than the other cultivars. Cd and Pb treatments significantly increased the NPTs in all four cultivars; the highest level was found in CR. Cd and Pb treatments also increased H 2 O 2 levels in all cultivars; the highest and lowest levels were observed in AG and CR, respectively. These results indicate that the greater Cd and Pb tolerance of CR may be attributable to its higher potential to limit Cd and Pb accumulation and to form complexes of metal-binding ligands with Cd and Pb. The results of this study provide information for the selection of the safest of the four common radish cultivars for growth in Cd-and Pb-contaminated soils.
