Arsenic Contamination Status in North America

Abstract

Arsenic (As) is a toxic and ubiquitously present element. It is present in some places of the world in excessively high concentrations in water and soil that threaten public health. North America constitutes one of the hotspots of As contamination. In Canada and the USA, a number of reports show the contamination of As in a number of food items including rice, rice-based products, fruits, beverages, animal food items, etc. Further, As contamination of water sources is also known to occur in different states of both Canada and the USA. Thus, the problem of As contamination is widespread and needs attention. This chapter provides an overview of As contamination of water and food sources of North America.
