中国环境镉接触人群低骨密度及肾功能不全的研究

25年前,Ambio曾载文提出应警惕环境镉污染引起的健康效应.1998年在中国进行了这方面的研究,评价了因食用大米而接触镉人群的前臂骨密度(BMD)和肾功能,发现尿镉(CdU)或血镉(CdB)高的绝经后妇女及血镉(CdB)高的男性,BMD均有所下降.在CdB或CdU与肾功能不全(视黄醇结合蛋白排泄增加)之间也发现了明显的、有统计学意义的剂量-效应关系及剂量-反应关系.第一次报道了日本以外的亚洲地区镉接触人群中存在骨不良效应.本文的意义在于阐明了亚洲的环境镉接触人群中仍存在着与肾和骨(镉的比较严重的有害效应)的联合效应,也讨论了一些欧洲镉接触人群的骨效应.     

CCall--healthy and successful work in call centres.

Call centre workplaces are in many ways a challenge to occupational health and safety. The occupation itself can be described as an IT information technology-supported, communication-intensive form of work with often unusual working hours and a high rate of part-time employment. Data on the employee turnover as well as absenteeism related to occupational disability is quite contradictory. Occupational safety and its proponents still have to find new ways into the corporate structures and cultures of this relatively new and rapidly growing branch of industry. In a 2-year research and development project, using a holistic approach and under consideration of all the relevant disciplines, call centre workplaces were studied, and organisational measures were developed and field tested by putting them into practice. Practical help was developed for a sustainable strategy for successful and healthy work in call centres.
