Seizurogenic chemicals include a variety of toxic agents, including chemical warfare agents, toxic industrial chemicals, and natural toxins. Chemical weapons such as sarin and VX, and pesticides such as parathion and carbaryl cause hyperstimulation of cholinergic receptors and an increase in excitatory neurotransmission. Glutamatergic hyperstimulation can occur after exposure to excitatory amin...

The infestation status of head louse among children attending primary schools and kindergartens in Chinju-shi, Kyongsangnam-do, Korea, was investigated between June and July 1999. Out of 2,288 children examined, 3.9% of boys (48/1,242) and 23.5% of girls (246/1,046) were infested with nits or adult/nymphs of lice. The effectiveness of lindane shampoo (1% gamma benzene hexachloride solution) was...

Lindane-degrading activity under aerobic conditions has been observed in two bacterial strains: UT26, phenotypically identified as Sphingomonas paucimobilis, and a new single unidentified isolate named RP5557T. The rrs (16S rDNA) sequences for both strains and the phenotypic characteristics for the unidentified isolate RP5557T were determined. RP5557T does not have high identity (less than 90% ...

This work describes the removal of lindane by persulfate activated with ferrioxalate under simulated solar light irradiation and circumneutral pH conditions. The influence main operating parameters is evaluated, a kinetic model based on radical mechanism proposed validated. To do this, synthetic solutions polluted different amounts oxidant catalyst were employed. Results show that it possible t...

The author used a recent article on lindane (γ-hexachloro-cyclohexane) reductive dechlorination by Fe/Pd bimetallics to point out that many other of published works in several journals do not conform to the state-of-the-art knowledge on the mechanism of aqueous contaminant removal by metallic iron (e.g. in Fe(0)/H(2)O systems). It is the author's view that the contribution of adsorbed Fe(II) to...
