| At the junction of two scientific disciplines,
environmental toxicology and molecular biology, Dr.
Ornella Selmin, PhD is investigating exactly why certain
toxins damage organisms and what we might be able to do about it.
focus is a chemical called Trichloroethylene or TCE, which is found
everywhere. In her laboratory in the Department of Veterinary Science
and Microbiology, Ornella is using a technique called micro-array
analysis to get a series of snapshots showing how much each gene is working
in the developing heart.
Chemical Safety and Hazard Investigation Board (CSB) is an independent
federal agency charged with investigating industrial chemical accidents.
Washington, DC, the agency's board members are appointed by the President
and confirmed by the Senate. The CSB conducts root cause investigations
of chemical accidents at fixed industrial facilities. Root causes are
usually deficiencies in safety management systems, but can be any factor
have prevented the accident if that factor had not occurred.
1974, Congress passed the Safe
Drinking Water Act. This law requires the Environmental Protection
Agency (EPA) to determine safe levels of chemicals in drinking water
which do or may cause
health problems. These non-enforceable levels, based solely on possible
health risks and exposure, are called Maximum
Contaminant Level Goals (MCLG).
The MCLG for trichloroethylene has
been set at zero because EPA believes this level of protection would not cause
any of the potential health problems
noted within this site.
