对上海某电池厂发生锰中毒进行了流行病学调查。该厂在干电池生产中使用大量MnO2（电池去极剂），由于防护措施不力，拌料车间空气中锰平均浓度高达107mg／m3。在九年中对76名接触MnO2者体检，发现标中毒5人，患病率高达6．5％，高于1980年全国标中毒普查的锰尘接触者锰中毒患病率0．28％的22倍之多。提示：应加强电池制造行业锰中毒的防护工作，促使电池制造业健康监护性体检形成制度化、法律化。
An epidemiological investigation of manganese poisoning in a battery factory in Shanghai was carried out. The plant uses a large amount of MnO2 (battery depolarizer) in the production of dry batteries. As a result of poor protective measures, the average concentration of manganese in the air of the mixing plant reaches as high as 107 mg / m3. In nine years, 76 people who were exposed to MnO2 were found to have 5 people who were poisoned, the prevalence was as high as 6.5%, which was higher than the prevalence of manganese poisoning by manganese poisoning of 0.28% 22 times as much. Tip: Should strengthen the battery manufacturing industry, manganese poisoning protection work, prompting battery manufacturing health care medical examination formed institutionalized and legalized.
