A cooperation was started between the Union of Physicians of Schleswig-Holstein (Bad Segeberg, Germany) and an environmental engineer in 1992. A mobile unit for environmental analysis was set up, the Environmental analysis Van (EAV) or mobile umweltambulanz. Inspection of sites and collection of air and dust/material samples for analysis of xenobiotics were performed on request. The results of this cooperation were evaluated to show which sources of indoor pollutants could be particularly relevant to human health impairment. During a 30-month period form July 1993 to December 1995, 1793 site inspections wer conducted. Xenobiotic analysis and subsequent advising was performed in 1318 cases; enhanced concentrations of one or more toxic substances (mainly biocides such a pentachlorophenol, permethrin, and/or hexachlorocyclohexane) were found in 71% of the sites analyzed. Formaldehyde, volatile organic compounds, and contamination by molds were also documented. A follow-up was done on 80 clients of the Environmental Analysis Van, which had detected elevated concentrations of permethrin because of pyrethroid-treated carpeting. The effect of removing all contaminated carpeting on health improvement in comparison with nonremoval was statistically significant (p<0.0001). Pyrethroid-treated carpeting, which was already 5, 7 and 10 years old, revealed permethrin concentrations of 115, 100, and 150 mg/kg dust. This result indicates that indoor contamination of permethrin is highly persistent and may be the cause of adverse health effects.
1992年，石勒苏益格-荷尔斯泰因州医师协会（德国巴特塞格贝格）与一名环境工程师展开了合作。他们设立了一个用于环境分析的移动单元，即环境分析车（EAV）或移动环境救护站。应要求对场地进行检查，并采集空气和灰尘/材料样本以分析外源性物质。对该合作的结果进行了评估，以确定哪些室内污染物来源可能与损害人体健康特别相关。在1993年7月至1995年12月的30个月期间，共进行了1793次场地检查。对其中1318个案例进行了外源性物质分析及后续咨询；在71%的被分析场地中发现一种或多种有毒物质（主要是五氯苯酚、氯菊酯和/或六氯环己烷等杀生物剂）浓度升高。甲醛、挥发性有机化合物以及霉菌污染也有记录。对环境分析车的80位客户进行了跟踪调查，这些客户的场地因使用含拟除虫菊酯的地毯而检测到拟除虫菊酯浓度升高。与未移除相比，移除所有受污染地毯对健康改善的效果具有统计学意义（p<0.0001）。使用了5年、7年和10年的含拟除虫菊酯地毯，其灰尘中拟除虫菊酯浓度分别为115、100和150毫克/千克。这一结果表明，室内拟除虫菊酯污染具有高度持久性，可能是健康不良影响的原因。
