Arsenic, a compound with a long history as a toxicant (Bolt 2012, 2013), continues to be a major public health issue in a number of countries worldwide (Golka et al. 2010; Martinez et al. 2011). As far as exposure is concerned, the most important matter of current publications is drinking water pollution (Maity et al. 2012; Deb et al. 2012; Guha Mazumder et al. 2012; Marchiset-Ferlay et al. 2012; Chen et al. 2012; Kumasaka et al. 2013). Another contemporary issue coming into focus is environmental contamination from (former) mining activities (Coelho et al. 2012; Li et al. 2012; Chakraborti et al. 2012) and from waste deposits (Moreno-Santini et al. 2012).
