Environmental Clastogens Detected by Meiotic Pollen Mother Cells of Tradescantia
Many airborne agents are routinely produced in large quantities from industrial effluents, vehicular emissions, agricultural fumigations and sprays, and from natural or man-made explosions. These common air pollutants, in both gaseous and particulate forms, are dissipated into the open air of large geographic areas of the globe. Other airborne agents, e.g. cigarette smoke, volatile cosmetics and common household pesticides, are more commonly release into small confined areas more intimately related to daily life. Humans are frequently acutely exposed to these latter pollutants at relatively high concentrations. The possible harmful effects of each of these agents and the possible synergistic interactions between them are essential topics in environmental studies.
