Single and combined use of Cannabis sativa L. and carbon-rich materials for the removal of pesticides and endocrine-disrupting chemicals from water and soil

摘要: Hemp (Cannabis sativa L.) seedlings were used to remove from water the fungicide metalaxyl-M and endocrine disruptor (EDC) bisphenol A (BPA) at concentrations ranging 2 100 μg mL-1. In 7 days of exposure, despite phytotoxicity each compound that reduced elongation biomass, able between 67 94% 86 95% BPA. The amounts BPA extracted plant dry biomass in range 106-3861 g-1 16-101 g-1, respectively, resulted positively correlated both dose added (P ≤ 0.01) amount removed by plants 0.01). Plant uptake transformation main mechanisms involved removal compounds. another set experiments, hemp was a mixture two pesticides, metribuzin, three EDCs, BPA, 17β-estradiol (E2), 4-tert-octylphenol (OP), 10, 1 soil column not with 2.5% (w/w) green compost (CM) or wood biochar (BC). 25 days, did alter considerably distribution compounds along profile capable removing, on average, 12, 11, 9, 14% metalaxyl-M, E2, OP, respectively. During growth, transformed accumulated part them (except OP) mainly shoots. CM and, especially, BC significantly protected toxicity enhanced retention latter soil, contrasting leaching. Thus, single synergistic use amendments deserves attention being very low-cost eco-sustainable strategy remediate soil.
