“…RAPD technique is a fundamental tool for genotoxicity studies and is efficiently used to detect DNA changes in plants influenced by metals [50,51]. Different stress factors including NPs can damage plant culture DNA, what can be shown as differences in band profiles [22,50,52]. The effect of exposition of Fe 3 O 4 NPs on the DNA damage was investigated in selected model plant system under in vitro conditions.…”

“…whereas new bands generally result in present mutations, large deletions, or homologous recombination [50,52]. This suggests that exposition on even low Fe 3 O 4 NPs concentrations (0.5 mg/l, 1 mg/l, and 1.5 mg/l) can induce damage in plant DNA level, which can result in mutation initiation.…”

“…Soil and water contamination by heavy metals causes bioaccumulation in plants thereby threatening human health through food chain [4]. Excessive metal accumulation in plants also results in oxidative stress due to production of reactive oxygen species [5,6,7,8]. Lead (Pb), in particular is most toxic because of its hazardous health effects on both animal and man [9,10].…”

“…The danger of heavy metals is 57 intensified by their almost indefinite persistence in the environment due to their absolute nature 58 which cannot be degraded (Gupta et al, 2016). Metals are non-biodegradable but can be 59 transformed through sorption, methylation, complexation and changes in valence state (Anyanwu 60 et al, 2011).61 4Toxic metals apply their toxicity in the displacement of essential metals from their normal 62 binding sites of biological molecules, inhibition of enzymatic functioning and disruption of 63 nucleic acid structure, oxidation stress, genotoxicity and interfering with signalling pathways 64 (Srivastava et al, 2017;Venkatachalam et al, 2017). Ecologically, the accumulation of heavy 65 metals in soils is extremely hazardous because soil is a major link in the natural cycling of 66 chemical elements; it is also a primary component of the trophic chain (Liu et al, 2012; Sagi and 67 Yigit, 2012; Wyszkowska, 2013).…”
