Preliminary evaluation of mental status and an investigation of occupational health knowledge demand in operating and maintenance personnel in wind power plants
Abstract [article in Chinese] —
Objective: To investigate the mental status, level of occupational health knowledge, health behaviors, and occupational health knowledge demand in operating and maintenance personnel in wind power plants, and to provide a basis for formulating protective measures of occupational health for operating and maintenance personnel in wind power plants. Methods: A cluster sampling was performed in regionally representative wind power plants in the wind power industry from May 2014 to June 2015, and the Symptom Checklist-90 (SCL-90) and a self-made evaluation questionnaire were used to investigate the general status, mental health, and occupational health knowledge demand in 160 operating and maintenance workers. Results: Of all respondents, 26.9% had mental health issues. The awareness rate of infectious disease knowledge and preventive measures was 11.9%. Of all workers, 96.5% wanted to know the occupational hazard factors in the workplace, and 96.3% wanted to get the knowledge of the prevention of related diseases. Conclusion: Mental health issues in operating and maintenance personnel in wind power plants cannot be neglected and there is a high demand for occupational health services and related knowledge. Comprehensive intervention measures for health promotion in the workplace should be adopted to improve working environment, enhance individual mental health education, increase the level of occupational health management, and protect the health of workers.

Analysis of occupational health examination data of operation and maintenance personnel in wind farm
目的： 分析风电场维护人员在岗期间职业健康检查结果，为该行业相关职业健康检查项目的设置提供依据。 方法： 于2013年3至7月，采用整群抽样的方法，选取某公司风电事业部所属17家风力发电场的运行维护人员151人作为观察组，该公司风电事业部叶片生产作业人员336人作为对照组。通过现场流行病学调查法、职业健康检查法、症状自评量表（SCL-90）和北欧肌肉骨骼疾患调查问卷（NMQ）了解风电场运行维护人员主要健康问题。 结果： 风电场运行维护人员下背痛发生率为88.7%，SCL-90各因子得分均高于对照组（P<0.05）；风电场运行维护人员收缩压、血小板计数、血清丙氨酸转氨酶水平均低于对照组人员，第1秒用力呼气容积（FEV(1)）与用力肺活量（FVC）比值（FEV(1)/FVC%）、直接胆红素水平、双耳高频和双耳语频均高于对照组人员，差异均有统计学意义（P<0.05）。 结论： 风电场运行维护人员下背痛和心理健康问题较突出，其职业健康检查项目应结合肌肉骨骼疾患及心理问题设置。 [click here for computer translation]

Wind farms (WFs) can affect the local climate, and local climate change may influence underlying vegetation. Some studies have shown that WFs affect certain aspects of the regional climate, such as temperature and rainfall. However, there is still no evidence to demonstrate whether WFs can affect local vegetation growth, a significant part of the overall assessment of WF effects. In this research, based on the moderate-resolution imaging spectroradiometer vegetation index, productivity and other remote-sensing data from 2003 to 2014, the effects of WFs in the Bashang area of Northern China on vegetation growth and productivity in the summer (June–August) were analyzed. The results showed that: (1) WFs had a significant inhibiting effect on vegetation growth, as demonstrated by decreases in the leaf area index, the enhanced vegetation index, and the normalized difference vegetation index of approximately 14.5%, 14.8%, and 8.9%, respectively, in the 2003–2014 summers. There was also an inhibiting effect of 8.9% on summer gross primary production and 4.0% on annual net primary production coupled with WFs; and (2) the major impact factors might be the changes in temperature and soil moisture: WFs suppressed soil moisture and enhanced water stress in the study area. This research provides significant observational evidence that WFs can inhibit the growth and productivity of the underlying vegetation.
