Would you eat them??



From the Denver Post:

Colorado health officials said Wednesday trout from the Animas River are safe to eat even after being exposed to contaminants from a massive wastewater spill last month.

"Most fish tissue analyzed after the Gold King mine release showed metals below detectable levels," the Colorado Department of Public Health and Environment said in a news release. "All results were below the risk threshold."

Officials say levels of mercury, selenium and arsenic in rainbow and brown trout from the Animas are within the range of levels in fish previously sampled in the state.

Wildlife officials worried trout in the Animas could be immediately tainted after the Aug. 5 spill above Silverton caused by the Environmental Protection Agency. Contaminants flowed into Cement Creek before draining into the Animas and subsequently flowing through three states and two American Indian tribes.

Leaching mines in the Upper Animas Mining District are suspected of lowering the fish population in the river over the past decade. Officials worried the release would speed up the problem.


"Because there is a potential for fish to concentrate metals in their tissue over time, the department and Colorado Parks and Wildlife will continue to monitor levels of metals in Animas River fish," the release said. "New data will be analyzed and results reported when available."

Danger isn't to the fish, imo. All the invertebrates are going to die off though. They are very susceptible to heavy metals and pH changes. So with no food the fish will die off or become very stunted.

Fish, or any predator, don't build up metals in their body through breathing, it is from what they eat. So the trout will eat the insects and crawfish full of metals, and the metals will slowly build up within the fish.

This is just fluff press to placate the public. I'm sure the biologist doing the surveys know that the fish won't show any affects yet. They are probably doing the tests to establish baselines. Others are using these tests to say "See nothing wrong here, move along."
