Monodisperse unfunctionalized polystyrene/divinylbenzene beads were prepared via Ugelstads two-step activated swelling procedure. The modification of the porous structure was achieved in two different ways, by either changing the kind and amount of diluent or the concentration of crosslinker. Overall 10

Styrene is widely used with significant human exposure, particularly in the reinforced plastics industry. In mice it is both hepatotoxic and pneumotoxic, and this toxicity is generally thought to be associated with its metabolism to styrene oxide. Styrene causes lung

Styrene is a highly reactive monomer widely used in the plastics industry. The potential for styrene to produce genotoxic effects has been studied extensively in experimental systems. Styrene can induce sister chromatid exchanges (SCE) and chromosome aberrations (CA) in vitro

Recently, health problems caused by environmental chemical substances present in daily life have been increasing, particularly developmental toxicities, the effects of which often become apparent only after a long developmental period. It is difficult to determine adverse transgenerational effects. Therefore
