Migrant interior construction workers are increasing in China. Construction workers are at an increased risk of work-related illness (WRI) due to prolonged exposure to and inhalation of dust. Dust concentrations in the air can be reduced significantly with effective respiratory protection measures. We assessed the dust exposure and factors associated with respiratory protection of migrant interior construction workers. The total dust concentration in the workplace ranged from 0.07 to 335.27 mg/m, with a total dust exceedance rate of 50.00%. The respiratory dust loading ranged from 0.03 to 220.27 mg/m, with a respiratory dust exceedance rate of 71.42 %. The highest total dust concentration occurred when masons were polishing cement walls. We performed a questionnaire survey of 296 persons in two cities in China, in which 87.84% had no respiratory protection or only one protection measure. Gender, workplace, respiratory disease, and protective attitude all had an effect on the level of respiratory protection. The dust exposure in most jobs exceeds hygiene standards. The respiratory protection of migrant interior construction workers in China is inadequate.
中国的外来务工人员数量在不断增加。由于长时间接触和吸入粉尘，建筑工人患与工作相关疾病（WRI）的风险增加。通过有效的呼吸防护措施，可显著降低空气中的粉尘浓度。我们评估了外来务工的室内建筑工人的粉尘暴露情况及其与呼吸防护相关的因素。工作场所的总粉尘浓度范围为 0.07 至 335.27mg/m，总粉尘超标率为 50.00%。呼吸性粉尘负荷范围为 0.03 至 220.27mg/m，呼吸性粉尘超标率为 71.42%。当瓦工打磨水泥墙时，总粉尘浓度最高。我们对中国两个城市的 296 人进行了问卷调查，其中 87.84%的人没有呼吸防护措施，或只有一种防护措施。性别、工作场所、呼吸道疾病和防护态度均对呼吸防护水平有影响。大多数工作场所的粉尘暴露量都超过了卫生标准。中国外来务工的室内建筑工人的呼吸防护措施不足。
