Retsch : Applications : Knowledge Base : Arsenic in rice

Arsenic is known to concentrate in the outer layers of a grain, so it is perhaps not surprising that brown rice might have higher levels of arsenic, as the process of polishing rice to produce white rice removes the surface layers, hence reducing the total arsenic in the grain. In brown rice, only the hull is removed. Arsenic concentrations found in the bran that is removed during the milling

The arsenic concentration in the effluent of the wastewater treatment plant (WWTP) was not correlated to the one in the gravel pit water, but may depend on the operating conditions of the WWTP or the changes in processes of the mill. The impact of this anthropogenic source of arsenic on the Moselle River was slightly larger in summer, when the flowrate was lower. Globally the impact of the
