9.4 Heavy Metals


So I found that paper regarding lead to be extremely interesting. I feel like we are currently in the same position that we were in when lead was first linked to negative health outcomes. It took decades and clinically symptomatic individuals for lead to be banned in the U.S. 

Once again, it took clinically symptomatic individuals for lead to be banned and we now know that there are effects at lower doses that cause no symptoms! No symptoms! This is why I think we are again in the same position. I think most of the chemicals used today have effects at low doses that show no symptoms, yet we are going to wait for years until we have clinically symptomatic individuals before we do anything about it.

  1. Hi Lorena,

    I agree with you that lead took clinically symptomatic and effects individuals health letter. However, it is a cumulative toxicant that affects multiple body systems and is practically harmful to young children. Young children are particularly vulnerable to lead poisoning because they absorb 4-5 time as much ingested lead as adults. Thank you for sharing your thought.
