Inorganic arsenic and its methylated metabolities were measured in 108 spot urine samples obtained from the medical surveillance programme of workers exposed to inorganic Arsenic in July 2006. 15% of the samples showed levels higher than limit value of 35 microg/L (mean value 23,9 microg/L). After the improvement of the working conditions, in August-October 2006, we collected a urinary sample from each of the 108 workers enrolled. A questionnaire was also administrated, in order to investigate the influence of occupational and non occupational factors on the urinary arsenic excretion. The median value of urinary arsenic was 15,12 microg/L; among the 108 samples, 5% showed levels higher than limit value. A significant difference was observed in relation with sea-food consumption and aging stratification. In conclusion, we have described a significant reduction of urinary arsenic excretion between the two phases of biological monitoring, likely due to a proper hygienic work-related intervention.
2006年7月，对从无机砷暴露工人医学监测项目中采集的108份随机尿样进行了无机砷及其甲基化代谢物的检测。15%的样本显示水平高于35微克/升的限值（平均值为23.9微克/升）。在改善工作条件后，于2006年8月至10月，我们从108名登记工人中每人采集了一份尿样。还发放了一份问卷，以调查职业和非职业因素对尿砷排泄的影响。尿砷的中位数为15.12微克/升；在108份样本中，5%的样本显示水平高于限值。在与海鲜消费和年龄分层方面观察到显著差异。总之，我们描述了两个生物监测阶段之间尿砷排泄的显著减少，这可能归因于适当的与工作相关的卫生干预措施。
