The problems and possible solutions surrounding the use of copper-based boat bottom paints. Series: “University of California Division of Agriculture and Natural Resources” [3/2004] [Public Affairs] [Agriculture] [Show ID: 8448]
Doing what we, as a society, can do to defend the world we depend on is of paramount importance.
However, it is important to note that the copper problem and toxicity of bottom paints is the opinion of the producer of this film, and there is an ongoing debate about the validity of these claims. (continued)
In short: the opposing view believes (knows, actually) that as cuprous oxide leaches from the paint, it converts to cupric oxide which is the stable form of copper in the environment and therefore not bio-available. What governing bodies should be concerned about is the level of bio-available copper in the waterways, not totaly copper.
As a viewer of this film please remember: what you are watching is opinion, not fact.
