A study of 67 subjects in a small titanium oxide paint factory in Nigeria showed 50-54% frequency for airway symptoms, 20-40% for neurological symptoms, and 10-27% for other symptoms. The symptoms were well correlated with exposure (p less than .05) and pulmonary function tests (PFTs). The directly exposed subjects had likelihood odds ratios of 5 to 17 of presenting symptoms compared to controls. The PFT deficit, relative to the expected value, was significantly higher for those with airway symptoms than for those of other symptom categories (p less than .005). There were 28 (42%) cases of restrictive lung impairment. Exposure to cotton dust had confounding influence on the PFT of subjects previously exposed. Smoking rate was very low. These findings indicate the need for worker protection in a manufacturing plant in Nigeria.
对尼日利亚一家小型氧化钛涂料厂的67名受试者进行的一项研究表明，呼吸道症状出现频率为50 - 54%，神经症状为20 - 40%，其他症状为10 - 27%。这些症状与接触情况（p小于0.05）和肺功能测试（PFT）密切相关。与对照组相比，直接接触的受试者出现症状的可能性比值比为5至17。相对于预期值，有呼吸道症状者的肺功能测试缺陷明显高于其他症状类别者（p小于0.005）。有28例（42%）出现限制性肺损伤。接触棉尘对先前接触过的受试者的肺功能测试有混杂影响。吸烟率很低。这些发现表明尼日利亚的一家制造工厂需要对工人进行保护。
