Frequent exposure to heavy metals can cause various health problems (Nagles Arancibia, Rojas, & Segura, 2012; Keawkim, Chuanuwatanakul, Chailapakul, & Motomizu, 2013; Xiao et al., 2014). Among the heavy metals, cadmium and lead have a great impact on biota. Cadmium can cause nephrotoxicity, and even lung cancer, when the amount of exposure to the said metal exceeds 26 µg/kg body mass on a monthly basis (Li et al., 2011; Chen et al., 2014; Aragay & Meroçi, 2012). Lead can greatly affect the nervous system (encephalopathy) and the hormones, and it can trigger some cancers at more than 0.02-3 μg/kg for adults and 0.03 to 9 μg/kg for children on a daily basis (Flora, Gupta, & Tiwari, 2012).
