Exposure to chronic high levels of copper can increase risk factors for lung cancer and coronary heart disease. Studies of copper mine workers both pre and post mortem have detailed the risk of chronic copper exposure and broken the risk up by parts of the copper mining processes ( smeltering, converting, plating) (11,12,13,14). Figure 3.
