Geochemical mapping is the base of knowledge needed to determine critical contents potential toxic elements and potentially hazardous regions on planet. This work presents maps baseline values chemical in soils Sal Island (Cape Verde) assessment their ecological human health risks. According results, Ba, Co, Ni, V are above international guidelines for agricultural residential proposed uses. Arsenic soil overlying Ancient Eruptive Complex shows a high risk factor. It not clear if As have geogenic or anthropogenic source. Hazard indexes (HI) were calculated children adults. For children, HI higher than 1 Cr, Mn, indicating non-carcinogenic risk. These present content covering Quaternary sediments, Monte Grande-Pedra Lume Formation, Complex, inducing belief other adults, there no Cancer (CR) was As, Cd, Ni exposures adults results mainly lower carcinogenic target value, cancer Only few samples CR slightly × 10−4 2 10−6 exposed Cr by inhalation. important emphasize that these associated with exposure likely overestimate bioavailable fractions once it used as aqua regia instead physiological fluids digest soil. However, since measured concentrations reveal they can be harmful both environment health, regional activities such agriculture water exploitation must controlled competent authorities. conclusions highlight insights applicability geochemistry surveys future policy progress, which particularly relevant developing countries like Cape Verde archipelago.

The Accumulation of Abscisic Acid Increases the Innate Pool of Soluble Phenolics through Polyamine Metabolism in Rice Seedlings under Hexavalent Chromium Stress

Toxics, Journal Year: 2024, Volume and Issue: 12(8), P. 577 - 577

Potential toxic element (PTE) pollution has emerged as a significant environmental and social concern in global agriculture. Chromium (Cr) occurs different oxidation states naturally, among them Cr(VI), which is highly toxic. This study carried out biochemical molecular tests to elucidate the accumulation of total soluble phenolics (TSPs) rice plants exposed Cr(VI) at 2.0, 8.0, 16.0 mg Cr/L, emphasizing interaction between polyamines (PAs) abscisic acid (ABA). The results revealed Cr tissues plants, hindered their growth. exposure increased ABA concentration, with higher levels detected shoots than roots. TSP concentration showed positive relationship supplied concentrations Cr(VI). measured PAs, including spermine (Spm), putrescine (Put), spermidine (Spd), exhibited varied responses stress, only Spm increasing concentrations. Real-time qRT-PCR PAs synthesis-associated genes such OsADC1, OsAIH, OsCPA1, OsCPA4 were significantly up-regulated shoot treated These are associated second pathway Put synthesis, originating from Arg. Almost all activated Met well. Moreover, involved interconversion three species completely exposure. Overall, analysis gene expression data indicate that likely enhance subjected toxicity.
