What about the second largest rice exporter, Thailand? This is what I found:

> In comparison, the American rice accumulated the highest arsenic concentration (mean 0.257 mg kg−1) followed by the Thai rice (mean 0.200 mg kg−1), the Pakistani rice (mean 0.147 mg kg−1), the Indian rice (mean 0.103 mg kg−1), and finally the Egyptian rice (mean 0.097 mg kg−1).

So the lowest is Egyptian rice?
