As a concern for the occupational health of the people working at the foundry we have implementing a chelating treatment in order to drop the lead levels in the blood to its normal parameter for people working in this kind of business.

Twenty-six employees began treatment with Bio-Chelat™, people with at least 40 u.g./dl. of lead in blood. The patients began with the treatment as follows:

First week at 15 drops daily
Second week at 30 drops daily
And four weeks more at 60 drops daily
Total weeks of treatment - Six weeks.

After finishing the six week treatment the patients had another blood test for lead, presenting a good decrease of lead in the blood.

The patients dropped their lead levels in an average of approximately 25 percent not considering patient number four because I think he did not follow the treatment at all. Also should be mentioned that no employee was off his job for this period, they all continued working in their usual area.

After this period of treatment looking the good results, I recommend to continue the use of Bio-Chelat™ in order to prevent future toxicity with lead.
