为了探讨磷肥生产工人,受氟对人体骨胳之影响,提供磷肥生产工人氟中毒的依据,我们于1983年对永和磷肥厂的磷肥工人进行了X线摄片检查等,现将结果报告如下。 对象与方法 一、对象 对从事磷肥生产者173人中选择64名生产工人作为观察组,工龄在0.6～19年,平均16.14年;选择与磷肥生产工人相近似的24名非生产人员作为对照组;两组人员均为男性。 二、检查部位 骨盆采用前后位片(上包括4、5腰椎,下包括耻骨联合),小腿正侧位片(包括膝关节、髌骨),前臂正位片(包括腕关节、肘关节)。骨盆、小腿用12~〃×15~〃的日本富士牌和国产胶片,前臂用11~〃×14~〃的国产胶片。
In order to explore the phosphate fertilizer production workers, the impact of fluoride on human bones, to provide fluoride phosphate production workers based on the evidence, we in 1983 Yonghe phosphate fertilizer plant phosphate workers X-ray examination, the results are reported below. Subjects and Methods I. Object To 64 workers engaged in the production of phosphate fertilizer as the observation group, the length of service was 0.6 to 19 years (average 16.14 years); 24 non-production workers similar to the phosphate fertilizer production workers were selected as the control group ; Two groups of men are men. Second, check the pelvis pelvic anteroposterior (including 4,5 lumbar, including the pubic symphysis), the lower leg is a lateral film (including the knee, patella), forearms are anteroposterior (including the wrist, elbow). Pelvis, leg with 12 ~ 〃 × 15 ~ 〃 Japan’s Fujifilm and domestic film, forearm with 11 ~ 〃 × 14 ~ 〃 domestic film.
