0.05 ± 0.03 (Williams et al. 2005; Meharg et al. 2009). Adomako et al. (2011) reported a mean i-As concentration of 0.091 mg kg-1 in white rice grown in Ghana while a median i-As concentration of 0.128 mg kg-1 (n = 44) was reported in long grain rice grown in the USA (US FDA 2013). In the present study, ~95% of total As was i-As. Adomako et al. (2011) reported a similarly high proportion of i-As in rice grown in Ghana (83%). By comparison, Pinson et al. (2014) reported ~half of total As was i-As in rice samples grown in Texas. Al-Rmalli et al. (2012) reported that 40-92% of total As was i-As in Bangladeshi rice while Williams et al. (2005) reported 80% i-As in Bangladeshi rice.
