Abstract Indigenous plants have been grown naturally and vigorously in copper contaminated soils. Thus, the aim of this study was to evaluate the phytoremediation ability of two indigenous plants naturally grown in two vineyard soils copper contaminated, and in a copper mining waste. However, it was evaluated the macro and micronutrient uptake and the potential of phytoremediation. So, a greenhouse study was carried out with Bidens pilosa and Plantago lanceolata in samples of vineyard soils (Inceptisol and Mollisol) copper contaminated, and in a copper mining waste. Plant growth, macro and micronutrient up take, tolerance index (TI), translocation factor (TF), metal extraction ratio (MER), bioaccumulation factor (BCF), plant effective number of the shoots (PENs), and plant effective number of the total plant (PENt) were analyzed. Both plants grown in vineyard soils showed high phytomass production and TI. P. lanceolata plants cultivated in the Inceptisol showed the highest copper concentrations in the shoots (142 mg kg–1), roots (964 mg kg–1) and entire plants (1,106 mg kg–1). High levels of copper were phytoaccumulated from the Inceptisol by B. pilosa and P. lanceolata with 3,500 and 2,200 g ha–1 respectively. Both B. pilosa and P. lanceolata plants showed characteristics of high copper hyperaccumulator. Results showed that both species play an important role in the natural copper phytoaccumulation in both vineyard soils contaminated with copper, being important to its phytoremediation.

Remedial Strategies

Total copper concentrations in some Victorian vineyard soils, due to the use of copper (Cu)-based fungicides, have increased to the point where remedial strategies need to be considered to avoid Cu toxicity. In Australia, the National Environment Protection (Assessment of Site Contamination) Measure recommends that total Cu concentrations in soil exceeding the threshold concentration of 100 mg/kg require environmental investigation. However, it is likely that some Cu-contaminated soils, to be used for horticultural purposes, will need to be remediated even if the total Cu concentration is <100 mg/kg. This paper examines some prospective remedial strategies for Cu-contaminated vineyard soils and demonstrates that, apart from stopping the addition of Cu, in situ remedial strategies are the only practical remedial options for Cu-contaminated vineyard soils. Active mixing, both lateral and vertical, of contaminated surface soil with less contaminated or uncontaminated deeper soil is an in situ and well-suited remedial option for most low and medium Cu-contaminated vineyard soils. The strategy relies on attenuation processes to be more effective. Other ameliorative strategies with potential as remedial options for low and medium Cu-contaminated soils, including phytoremediation and attenuation (liming and addition of organic matter), are also considered.

ABSTRACT: Phytoremediation is an alternative technique used to treat copper-contaminated soils. The objective of this research was to explore the behavior of nine summer cover crops regarding the growth, absorption and translocation of copper in soils with contamination levels exceeding the Value of Prevention, with a view to selecting plants for phytoremediation programs. In the experiments the Cambisol was contaminated with copper, added in doses of 0, 100, 200, 400, 500 and 600mg kg-1, in which the following nine plants were cultivated under greenhouse conditions: Canavalia ensiformis, Cajanus cajan, Dolichos lablad, Mucuna cinereum, Mucuna aterrima, Crotalaria juncea, Crotalaria spectabilis, Pennisetum glaucum and Paspalum notatum. At 90 days after sowing the plants were evaluated for dry mass of shoot and root, Cu, N, P, K, Ca, Zn, and Fe levels in the shoot and Cu in the roots. High soil Cu levels induced a decline in the phosphorus absorption by the plants. Canavalia ensiformis displayed high potential for phytoextraction as these plants could translocate high copper concentrations to the aerial plant parts, while the Mucuna cinereum and M. aterrima are indicated for the copper phytostabilization programs, due to the high copper accumulation in their root systems.
