A longitudinal study of neuropsychological and neuromotor effects of low level manganese exposure

这项研究将调查低水平接触锰颗粒物对神经心理和神经运动的影响。以前的研究已经指出了高水平暴露的症状，但文献中关于低水平暴露的影响存在争议。我们的目标是改进累积暴露的测量方法，并制定一项比迄今报道的更全面和更敏感的测试方案。这些措施和方案将纳入纵向设计，到目前为止还没有进行研究研究。此外，还将开发一个暴露变量数据库，以促进对低水平暴露的影响进行长期、准确的研究。

This study will investigate the neuropsychological and neuromotor effects of low level exposure to mangenese particulate. Previous studies have indicated symptomology of high level exposure, but there is contention in the literature regarding the effects of low levels of exposure. Our aim is to refine measures of cumulative exposure and develop a more comprehensive and senstitive testing protocol than has been reported thus far. These measures and protocols will be incorporated into a longitudinal design, which has not been conducted in research studies to date. In addition, a database of exposure variables will be developed to facilitate long-term, accurate research into the effects of the low levels of exposure.
