“…La determinación del potencial antioxidante de las plantas tolerantes al DDT para su uso en fitorremediación se ha examinado en alfalfa y soya (Mitton, Ribas-Ferreira, Gonzalez, Miglioranza & Monserrat, 2016), y en tomate y calabacín (Mitton, Gonzalez, Monserrat & Miglioranza, 2018). La respuesta antioxidante es dependiente de la especie vegetal, la concentración de los contaminantes y las condiciones de cultivo.…”

“…La soya fue más susceptible al DDT, con disminución en la respuesta de la actividad GST y baja acumulación de DDT (Mitton et al, 2016). En las plantas de tomate y calabacín, el DDT incrementó significativamente las actividades de las enzimas catalasa, glutatión reductasa y glutatión peroxidasa; disminuyendo (~50%) la actividad GST por exposición a 63.5-101.3 µg de DDT/kg suelo (Mitton et al, 2018).…”

El DDT (Dicloro Difenil Tricloroetano o 1,1,1-tricloro-2,2-bis-etano) representa un riesgo importante para la salud humana, debido a que se asocia con enfermedades como cáncer de mama, Alzheimer, Parkinson y su acumulación en sangre. Los recientes hallazgos del uso clandestino del DDT como agroquímico hacen necesaria la implementación de tecnologías de recuperación de suelos agrícolas contaminados con este compuesto. La fitorremediación es una tecnología sustentable, que utiliza el potencial de las plantas para remover contaminantes orgánicos e inorgánicos. Esta tecnología es mejorada con la inoculación de microorganismos rizosféricos que median el transporte de nutrientes y degradan compuestos orgánicos como el DDT. Esta revisión recopila información científica de los últimos diez años sobre: fitorremediación y fitorremediación asistida por microorganismos en sitios contaminados por DDT, y sus metabolitos diclorodifenildicloroetileno (DDE) y diclorodifenildicloroetano (DDD. Además, se resaltan los puntos más importantes que hacen de la fitorremediación una estrategia para la recuperación de suelos contaminados con DDT, DDE y DDD.

“…The insecticide 4,4 0 -DDT has been widely used for pest control because of its low cost, broad spectrum activity and high residual biological activity. Although its use has been prohibited for agricultural purposes, because of the negative impact on wildlife and human health, it remains adsorbed to soil particles, leading to half-lives of up to 30 years in this matrix (Mitton et al 2014(Mitton et al , 2018. Is known that before 1989 (during communism period) extensively use of the land for agricultural purpose implied the use of high quantities of pesticides and chemical fertilizers.…”

In this study, 41 tomato samples were investigated by means of stable isotope ratios (d 13 C, d 18 O and d 2 H), elemental content, phenolic compounds and pesticides in order to classify them, according to growing conditions and geographical origin. Using investigated parameters, stepwise linear discriminant analysis was applied and the differences that occurred between tomato samples grown in greenhouses compared to those grown on field, and also between Romanian and abroad purchased samples were pointed out. It was shown that Ti, Ga, Te, d 2 H and d 13 C content were able to differentiate Romanian tomato samples from foreign samples, whereas Al, Sc, Se, Dy, Pb, d 18 O, 4,4 0 -DDT could be used as markers for growing regime (open field vs. greenhouse). For the discrimination of different tomato varieties (six cherry samples and fourteen common sorts) grown in greenhouse, phenolic compounds of 20 samples were determined. In this regard, dihydroquercetin, caffeic acid, chlorogenic acid, rutin, rosmarinic acid, quercetin and naringin were the major phenolic compounds detected in our samples. The phenolic profile showed significant differences between cherry tomato and common tomato. The contents of the chlorogenic acid and rutin were significantly higher in the cherry samples (90.27-243.00 lg/g DW and 160.60-433.99 lg/g DW respectively) as compared to common tomatoes (21.30-88.72 lg/g DW and 24.84-110.99 lg/g DW respectively). The identification of dihydroquercetin is of particular interest, as it had not been reported previously in tomato fruit.

“…The latter responds efficiently to sulfentrazone phytoremediation with an increased plant density (Ferraço et al, 2017). Recent evidences indicate that planning phytoremediation strategies and the selection of tolerant species are directly related to antioxidant responses induced by pesticide exposure (Mitton et al, 2018).…”

Winter Species Promote Phytoremediation of Soil Contaminated with Protox-Inhibiting Herbicides

et al. 2019

Phytoremediation comprises one of the main forms of decontamination of organic and inorganic substances in the soil, being economically viable and with a low environmental impact. The aim of this study was to verify the efficiency of winter plant species in the phytoremediation of soil contaminated with fomesafen and sulfentrazone using cucumber as an indicator species to the presence of residue. The experimental design was a completely randomized design arranged in a 6 x 4 factorial scheme with four replications for each herbicide. Factor A consisted of the phytoremediator species black oats, garden vetch, radish, bird's-foot trefoil, white lupine, and a treatment without prior cultivation. Factor B, on the other hand, consisted of the doses of fomesafen (0.000, 0.125, 0.250, and 0.500 kg h -1 ) or sulfentrazone (0.000, 0.300, 0.600 and 1,200 kg ha -1 ) applied in crop pre-emergence. At 45 days after sowing, the phytoremediator species were cut close to the soil. Subsequently, the bioindicator species of herbicide residues in the soil (cucumber) was sown in the pot. Phytotoxicity of herbicides to cucumber plants was assessed at 7, 14, 21, and 28 days after emergence (DAE). At 28 DAE, leaf area, height, and dry matter were determined in the bioindicator plant. Fomesafen and sulfentrazone doses interfered negatively with the assessed variables of cucumber when cultivated in succession to phytoremediator species. Cucumber phytotoxicity increased for all potential phytoremediator species as fomesafen and sulfentrazone doses increased. Sulfentrazone residues promoted the highest toxic effects on the bioindicator plant when compared to fomesafen. In general, black oats, radish, and white lupine were the species with the highest capacity to phytoremediate soil contaminated with fomesafen and sulfentrazone when applying the dose and twice the recommended doses of the herbicides.Keywords: Cucumis sativus, carryover, soil remediation. RESUMO -A fitorremediação compreende uma das principais formas de descontaminação de substâncias orgânicas e inorgânicas no solo, economicamente viável e de baixo impacto ambiental.
