high levels of arsenic in american

[ezlehappy]

From Fish bytes by Utah Outdoors.

Special notice: A health advisory has been issued for the North Fork of American Fork Creek because of elevated levels of arsenic. Anglers are encouraged to limit fish consumption to one cutthroat or brown trout per month taken from that section of stream. Pregnant women and children should not eat fish from this stretch. Signs are posed to identify the area of concern. Sampled rainbow trout in Tibble Fork Reservoir have not shown elevated levels of arsenic. The arsenic apparently comes from natural sources and from mine tailings.

Ezle,

I took a college course several years back and part of the course we studied how fish flesh could accumulate poisons and hold them. We were studying about tuna and mecury. The professor said that as insects and other organisms became carriers of toxins and pollutants and fish ate them, the fish flesh would carry and absorb the poisons into its flesh; thus posing a thread for human consumption. He went as far as to say some of the pollutants coming down rivers may be absorbed into the flesh of trout.

I decided back then that I would only eat trout out of pure mountain streams and lakes. I guess the kicker is: how do you tell what is pure?
