Graduates from the Biological Sciences program will have demonstrated: An understanding of the tenets of modern biology and an understanding of how cellular functions are integrated from the molecular level to the cellular level, through to the level of organism, populations and functioning ecosystems.
Toxic hazard studies of flexible polyurethane foam include small scale testing and large. scale testing. The combustion modes examined include thermal decomposition, smoldering, and open flaming, and under ventilated flaming combustion. Of the small-. scale studies, only a few include smoldering foam.
Long-term Health Effects. Researchers have linked chronic exposure to even small amounts of the styrene in polystyrene foam to depression and hormonal dysfunction. Studies indicate that styrene mimics estrogen and can interfere with hormone balances, potentially causing thyroid trouble and menstrual irregularities.
