“…In addition, Paisio et al (2009) showed that survival of Rhinella arenarum larvaes was not significantly affected by H 2 O 2 concentrations ranging from 0.1 to 0.6 mM. However, in that study, a solution containing 1 mM H 2 O 2 was toxic and produced a significant mortality.…”

“…As is well-known, phenols are commonly used in several agricultural applications, and they are also released from coal and petroleum refining activities. They constitute a risk to human health, due to their toxic, carcinogenic, mutagenic, and teratogenic effects (Entezari and Pétrier 2004;Paisio et al 2009). Thus, they are considered as priority pollutants in the US EPA list and their discharge in the aquatic environment is beginning to be restricted.…”

In the present work, Brassica napus hairy roots (HR) were used for phenol removal assays. The toxicity of post-removal solutions (PRS) and phenol solutions was analyzed. These HR removed the contaminant with high efficiency (100-80% for phenol solutions containing 10-250 mg/L, respectively). Phenol solutions treated with B. napus HR showed a significant reduction of general toxicity compared to untreated phenol solutions, since the IC50 values were 318.39 and 229.02 mg/L, respectively. Moreover, PRS presented lower cytotoxicity and genotoxicity than that found in phenol solutions untreated. The mitotic index (MI) observed in meristematic cells treated with PRS (100 and 250 mg/L of phenol) showed an increase of 35% and 42%, whereas the chromosome aberrations showed a significant decrease. According to these results, B. napus HR cultures could be used for the treatment of solutions contaminated with phenol, since we observed not only high removal efficiency, but also an important reduction of the general toxicity, cytotoxicity, and genotoxicity.

“…are mainly released at low temperatures, i.e., 300-450 • C from cellulose [26]. Phenol and its derivatives have a high potential toxicity for animal and plant species [27]. However, previous studies have shown that the concentration of phenol and its derivatives in pyrolytic bio-oils is not sufficient to account for the observed pesticidal activity [10,11].…”

“…However, Paisio et al (2009) reported that phenol concentrations in the 50-600 mg L -1 range still occur in aquatic environments. These concentrations may potentially harm the growth and propagation of aquatic species and cause serious health issues in humans (D'Alessandro et al 2012).…”

Plant samples and cultivationPlant s amples of P. orientale were collected from the Fenhe River wetland (37°51′N, 112°30′E), Taiyuan, Shanxi province, China (Fig. 1a). After diseased and yellowing leaves were removed, the plants were washed. The roots were soaked in 0.1% KMnO 4 for 10 minutes to kill the microorganisms. Vol. 41 no. 3 pp. 39-46 PL ISSN 2083-4772 DOI 10.1515/aep-2015 Abstract: Polygonum orientale with beautiful red fl owers can be found as one dominant species in the vicinity of most water bodies and wetlands in China. However, its phytoremediation potential has not been suffi ciently explored because little is known about its resistance to inorganic or organic pollutants. We investigated P. orientale response to low and moderate levels of phenol stress (≤ 80 mg L -1 Archives of Environmental Protection). Endpoints included phenol tolerance of P. orientale and the removal of the pollutant, antioxidant enzyme activities, damage to the cell membrane, osmotic regulators and photosynthetic pigments. In plant leaves, phenol stress signifi cantly increased the activities of peroxidase (POD) and catalase (CAT), as well as the contents of proline, soluble sugars and carotenoids, whereas superoxide dismutase (SOD), H 2 O 2 and electrolyte leakage (EL) levels remained unaltered. On the other hand, there were signifi cant decreases of soluble protein and chlorophyll contents. We demonstrated that, in combination with phenol tolerance and its removal, P. orientale has effi cient protection mechanisms against phenol-induced oxidative damage (≤ 80 mg L -1 ). We propose that P. orientale could be used as an alternative and interesting material in the phytoremediation of phenol.
