| Abstract |
The project studied the effects of lead-zinc mining and milling pollution in the Viburnum Trend or 'New Lead Belt' of S.E. Missouri. Results obtained from the project included the following: Stream pollution below the mine discharge was mainly due to the growth of large algal mats of Oscillatoria and bacteria which appear to result from the discharge of sodium isopropyl xanthate in the milling waste water; Limits were established for the precipitation of lead, zinc, and copper in relationship to pH and other water quality parameters; The amount of fluorides, in the streams may be used as an indicator of mining water discharges; New techniques may be used to evaluate organic milling reagents in the water and in the biota; Diatoms may be used as biological indicators of mine waste water effects.
