研究了甲醇中15种有机氯农药长期稳定性和短期稳定性，以寻找合适的长期保存条件和运输条件。长期稳定性考察了－18℃冷冻和室温条件不同贮存时间时样品的稳定性；短期稳定性模拟运输过程中环境温度和运输时间，重点考察高温时样品的稳定性，测定数据采用趋势分析法进行评价。结果表明，甲醇中15种有机氯农药标准样品的长期保存条件为－18℃冷冻，运输条件是在40℃高温下至少可以稳定保存15 d，为后续标准样品稳定性研究提供了参考。
In order to find suitable storage environmental and transport condition for organochlorine pesticides( OCPs) in methanol reference material, long?term stability and short?term stability were discussed. According to directives for the work of reference materials ( GB/T 15000 ) , long?term stability was tested in the different time and different temperature such as room temperature and-18 ℃. And short?term stability was investigated by simulating transport conditions such as temperature and shipping time, especially for high temperature. All the data from stability were evaluated using a linear regression model. The results showed that the long?term stability for OCPs in methanol reference material was-18℃, and the transport was stable for at least 15 days at 40℃. It is reference for the stability of other reference materials.
