问题     Dr. John Sterngold worked in the emergency room of a hospital in Willits, CA.
    The hospital was near a chrome-plating plant. The plant let off a dangerous gas called Chromium Ⅵ.
    Dr. Sterngold got very sick with asthma and had to quit working at the hospital.
    Many other citizens of Willits became ill with tumors, cancer, and asthma.
    Many scientists believe that the gases from the plant caused the illnesses,
    Thirty years ago Chromium Ⅵ was known to cause cancer. Twenty years ago scientists found there was no safe level of exposure to Chromium Ⅵ. But the company, Remco, was allowed to continue giving off the chemical until 1995. How could this happen?
    Many chemicals are used in industry without knowing if they are dangerous.
    Sometimes, industry and business are more important than the health of the people.
