Background and aims Soil amendments are often added to polluted soils to increase phytoremediation efficiency.Here we investigated the potential of a range of organic amendments for phytoextraction of heavy metals in a contaminated sediment.Methods Two experiments compared adsorption and phytoextraction of heavy metals by a Cdhyperaccumulator Carpobrotus rossii grown in the contaminated sediment amended with six organic amendments. Results The adsorption capacity as measured by Langmuir adsorption maximum followed the order of Cr > Zn > Cu > Cd, and the effect of organic amendments followed the order of chicken manure > cow manure > brown coal > golden wattle biochar > blue gum biochar > radiata pine biochar. The addition of amendments increased the adsorption of heavy metals, with brown coal resulting in the lowest concentrations of water-extractable Cd, Cu and Zn. Two manures resulted in the highest concentrations of these waterextractable heavy metals in the rhizosphere soil of C. rossii. Furthermore, brown coal resulted in higher shoot accumulation of these heavy metals than three wood-derived biochars, whilst the manures generally had the lowest accumulation of Cd and Cu although they increased shoot biomass. Conclusions The addition of brown coal decreased whereas manure addition increased the mobility (water-extractable fraction) of heavy metals in rhizosphere soil. Phytoextraction of Cd and Cu was greater with brown coal than with biochars or manures. Brown coal is suitable for enhancing phytoextraction of these heavy metals because it could increase their accumulation in shoots of C. rossii and decrease the risk of leaching of these heavy metals into groundwater.

“…O esterco, dependendo de sua origem, pode conter metais pesados provenientes principalmente dos aditivos usados na alimentação animal (Alloway, 1990;O'Neill, 1993;Nicholson et al, 2006;Li et al, 2006;. Além dos fertilizantes minerais, a água é outra fonte de contaminação que deve ser considerada em áreas irrigadas na região desse estudo.…”

RESUMOCom a utilização intensiva de agroquímicos, os solos cultivados podem ter o teor de metais pesados disponíveis às plantas aumentado com possível contaminação subsequente da cadeia trófica. Propôs-se, no presente trabalho, avaliar a influência do tempo de uso agrícola de um Cambissolo Háplico cultivado com meloeiro (Cucumis melo L.) sob o acúmulo de metais pesados e as características químicas do solo. O solo com plantios de meloeiro com um, dois e três anos de implantação foram avaliados, além de uma área de vegetação natural, nas camadas de 0-20 e 20-40 cm de profundidade. Os resultados mostraram que o tempo de cultivo alterou as características químicas do solo, com aumento do pH e do teor de N, P e K nas duas camadas de solo estudadas; já os teores de Ca foram diminuídos pelo cultivo. Houve acréscimos no teor total e disponível de Ni, Pb, Cu e Mn, na camada superficial, em função do tempo de cultivo do solo, enquanto os teores totais de Fe e Zn foram reduzidos em ambas as camadas avaliadas, no entanto, os teores disponíveis ainda são relativamente baixos. Palavras-chave: elementos traços, biodisponibilidade de metais, contaminação de solosAccumulation of heavy metals and chemical alterations in a Ultisol cultivated with melon ABSTRACT Soil cultivation using agrochemicals may increase the concentration of availability of heavy metals to plant and cause contamination of the trophic chain as well. This work was carried out to evaluate the influence of length of time under cultivation with melon (Cucumis melo L.) on the heavy metals accumulation and chemical alterations in Ultisol. Melon plantations of one, two and three years were studied. A benchmark area under natural vegetation was used to compare the data obtained. The results showed that the lengthiest time under cultivation altered the chemical characteristics of the soil. An increase in pH and contents of N, P and K was observed for the two soil layers evaluated. On the other hand, Ca contents were decreased by cultivation. The larger the cultivation time the higher the concentration of N, Pb, Cu, and Mn in the soil surface layer, whereas the Fe and Zn concentrations were diminished in both analyzed soil layers, though available concentrations are still regarded as low in soil.

“…after the incorporation of FYM into the soil. According to Li et al (2006), phytoavailability of Cd in cherry-red radish (Raphanus sativus) was reduced by the addition of chicken and pig manure composts. Different responses of FYM to phytoavailability of metals might be due to the variation in source of FYM and plant species of concern (Putwattana et al, 2010).…”

Due to the fact that possible risk associated with soil-crop-food chain transfer, metal contamination in croplands has become a major topic of wide concern. Accumulation of toxic metals in edible parts of crops grown in contaminated soils has been reported from number of crops including rice, soybean, wheat, maize, and vegetables. Therefore, in order to ensure food safety, measures are needed to be taken in mitigating metal pollution and subsequent uptake by crop plants. Present paper critically reviewed some of the cost effective remediation techniques used in minimizing metal uptake by crops grown in contaminated soils. Liming with different materials such as limestone (CaCO 3 ), burnt lime (CaO), slaked lime [Ca(OH) 2 ], dolomite [CaMg(CO 3 ) 2 ], and slag (CaSiO 3 ) has been widely used because they could elevate soil pH rendering metals less-bioavailable for plant uptake. Zn fertilization, use of organic amendments, crop rotation and water management are among the other techniques successfully employed in reducing metal uptake by crop plants. However, irrespectively the mitigating measure used, heterogeneous accumulation of metals in different crop species is often reported. The inconsistency might be attributed to the genetic makeup of the crops for selective uptake, their morphological characteristics, position of edible parts on the plants in respect of their distance from roots, crop management practices, the season and to the soil characteristics. However, a sound conclusion in this regard can only be made when more scientific evidence is available on case-specific researches, in particular from long-term field trials which included risks and benefits analysis also for various remediation practices.
