“…Bongoua-Devisme et al [22] revealed that Pontoscolex corethrurus can alleviate Cr and Ni tolerance of Acacia mangium. Likewise, Rhizoglomus clarum integration increases the phytoextraction capacity of Canavalia ensiformis plants in sandy soil contaminated with Cu [161]. Incorporation of Brassica juncea plants with Eisenia fetida earthworm enhances significantly the detoxification efficiency of Cd [86].…”

Toxic metal contamination of soil is a major environmental hazard. Chemical methods for heavy metal's (HMs) decontamination such as heat treatment, electroremediation, soil replacement, precipitation and chemical leaching are generally very costly and not be applicable to agricultural lands. However, many strategies are being used to restore polluted environments. Among these, phytoremediation is a promising method based on the use of hyper-accumulator plant species that can tolerate high amounts of toxic HMs present in the environment/soil. Such a strategy uses green plants to remove, degrade, or detoxify toxic metals. Five types of phytoremediation technologies have often been employed for soil decontamination: phytostabilization, phytodegradation, rhizofiltration, phytoextraction and phytovolatilization. Traditional phytoremediation method presents some limitations regarding their applications at large scale, so the application of genetic engineering approaches such as transgenic transformation, nanoparticles addition and phytoremediation assisted with phytohormones, plant growth-promoting bacteria and AMF inoculation has been applied to ameliorate the efficacy of plants as candidates for HMs decontamination. In this review, aspects of HMs toxicity and their depollution procedures with focus on phytoremediation are discussed. Last, some recent innovative technologies for improving phytoremediation are highlighted.

“…The total U accumulation (shoots + roots) in the CM+E treatments were increased by 68.5% for Indian mustard and 85.0% for sunflower compared to their respective CK treatments, indicating that the earthworm–cattle manure cooperation enhanced the uranium phytoremediation of Indian mustard and sunflower and facilitated the process of phytoextraction. Similarly, studies have shown that the phytoremediation of Zn by ryegrass and Indian mustard, Pb by Neyraudia reynaudiana , Cu by Canavalia ensiformis, Se by bean plant Phaseolus vulgaris L, and Cd by vetiver grass were enhanced with the inoculation of earthworms.…”

“…Nevertheless, the RE of uranium was improved with the application of cattle manure and the inoculation of earthworms, which was more obvious for sunflower. The presence of earthworms stimulated the translocation of Cu in Canavalia ensiformis . Also, Li et al (2018) found that the BCF, TF, and RE of heavy metals (Pb, Cd, Zn) were improved with the addition of earthworms, with the increase in heavy metal availability in soil due to earthworm activities …”

“…The phytoremediation efficiency of Neyraudia reynaudiana for lead–zinc mine contaminated soil was improved under the interactive effect of earthworms and EDTA, with 7.1–16.9-fold increasing for the accumulation of lead (Pb) in Neyraudia reynaudiana . The combined inoculation of arbuscular mycorrhizal fungi and earthworms increased the growth and copper (Cu) content of aerial plant tissues, yielding a 200% increase in Cu accumulation in the Canavalia ensiformis shoots . Azhar et al (2020) investigated the effects of earthworm Eisenia fetida activity on selenium (Se) bioavailability in soil and the subsequent bean plant Phaseolus vulgaris L uptake, and the results suggested that phytoextraction of Se could be assisted using earthworms .…”

Wars and military testing have resulted in the depleted uranium (DU) contamination of military proving grounds. In the present study, a pot experiment was conducted to explore the effects of earthworms on the uranium phytoremediation process. Effects of cattle manure and Eisenia fetida on biomass and U accumulation of plants, U solubility, and pH in soil were investigated using DU-contaminated soil from Yuma Proving Ground in Arizona, U.S. Results showed that the growth of plants was promoted with the addition of cattle manure and earthworms, which was more obvious for sunflowers. Moreover, the U accumulation was significantly enhanced by earthworms and cattle manure, with a 68.5% (Indian mustard) and 85.0% (sunflower) increase in the cattle manure plus earthworm treatments, and the removal efficiencies of U were correspondingly improved. No significant effect on soil pH was observed, while the soil water extractable U was increased by 84.9–87.8% in the earthworm treatments. Moreover, after the 4-week cultivation, cattle manure benefited the survival of earthworms and slightly increased their average fresh weight in DU-contaminated soil. Therefore, this study concludes that earthworms combined with agricultural organic wastes was an alternative approach to effectively remediate DU-contaminated soils in firing ranges.

“…Diversos solos, principalmente os agrícolas encontra-se contaminados com cobre. Algumas atividades como a mineração, a fundição, a incineração de resíduos, queima de carvão para fonte de energia, curtumes, lançamentos de efluentes, aplicação de fungicidas cúpricos e adubação com dejetos de suínos causam o aumento do teor de cobre no meio ambiente, que por consequência provoca efeitos deletérios em muitos dos organismos que ali habitam (BRUNETTO et al, 2014;FORMENTINI et al, 2015;SANTANA et al, 2019). Os riscos da contaminação por cobre são ainda maiores em solos de textura arenosa, devido ao baixo teor de argila e matéria orgânica o que resulta em baixa capacidade de troca de cátions fazendo com que a maior parte do cobre adicionado ao solo resulte em formas disponíveis aos organismos (BRUNETTO et al, 2014).…”

O cobre em excesso no solo provoca graves problemas ambientais. Este problema é maior quando o solo apresenta textura arenosa o que favorece a disponibilidade do metal aumentando os riscos aos organismos do solo. O objetivo deste estudo foi avaliar o efeito toxicológico do cobre em minhocas da espécie Eisenia andrei em um solo arenoso. Um solo arenoso foi coletado e adicionado de quatro doses de cobre na forma de sulfato de cobre, 0, 60, 120 e 240 mg Cu kg-1. Este solo foi utilizado para a realização de um teste de fuga e um teste agudo utilizando minhocas da espécie Eisenia andrei. Foi determinada a porcentagem de fuga, o incremento médio de peso, biomassa e a sobrevivência dos indivíduos. A presença do cobre em excesso resultou em toxidez ao organismo das minhocas. No solo contaminado com cobre houve elevado evitamento das minhocas, com maior porcentagem para as doses de 120 e 240 mg kg-1 de cobre. O período de exposição ao contaminantes não resultou em perda ou incremento de peso. A presença do cobre, principalmente nas doses altas, resultou na redução da biomassa de Eisenia andrei.
