  • Our school science laboratory has mercury compounds (mercuric oxide, mercuric nitrate and mercurous nitrate) that have been used in chemistry experiments. I am familiar with the adverse environmental and health effects of mercury. Should we still be using these compounds in our school?
    Effective January 1, 2001 Adobe Acrobat Reader Symbol, no school in New Hampshire is allowed to use or purchase elemental mercury, mercury compounds, or mercury-added instructional equipment and materials in grades K-12, except measuring devices and thermometers for which no adequate substitutes exist. Unfortunately, Chapter 278, Laws of 2000, which specifies these requirements, does not fund the removal of mercury products from a school. Therefore, it is up to each individual school to pay for the costs associated with removing mercury compounds from their classrooms and laboratories.
