Enhanced Degradation of Halogenated Aliphatics by Zero‐Valent Iron
TL;DR: In this article, the degradation process appeared to be pseudo first-order with respect to the organic compound, with the rate constant appearing to be directly proportional to the surface area to volume ratio and increasing with increasing degree of chlorination.
Journal ArticleDOI
Low dose mercury toxicity and human health.
TL;DR: Decreased performance in areas of motor function and memory has been reported among children exposed to presumably safe mercury levels and disruption of attention, fine motorfunction and verbal memory was also found in adults on exposure to low mercury levels.
