当涉水产品在水中溶出物质的浓度在10～50μg／L之间时，应如何进行毒理学安全性评价？

答案：

参考答案：

水质监测采样点的设置应有代表性，应分别在水源取水口、出厂水口和居民经常用水点处。管网水的采样点数，一般按供水人口每2万人设一个点计算，供水人口在20万人以下、100万人以上时，可酌量增减。在全部采样点中，应有一定的点数选在水质易受污染的地点和管网系统陈旧部分等处。每一采样点，每月采样检验应不少于两次，细菌学指标、浑浊度和肉眼可见物为必检项目，其他指标可根据当地水质情况和需要而定。对水源水、出厂水和部分有代表性的管网末梢水至少每半年进行一次常规检验项目的全分析。对于非常规检验项目，可根据当地水质情况和存在问题，在必要时具体确定检验项目和频率。

     Taxes are a big part in the United States. Most Americans pay city taxes, state taxes, social security (安全)
taxes, sales taxes… and the list seems endless. The biggest tax for most Americans is the incomes tax. The
personal income tax is called a "progressive tax", because it takes more from those who earn (挣钱) most. For
example, a person who earns about ＄3,500 a year, will pay a tax of only about 3.5% of earning, but if the
same person earned ＄85,000 a year, he would pay an income tax of 35%. Over years the incomes tax has
become more and more difficult for people to understand. Almost one half of all Americans now have to pay
experts to prepare their tax reports. In fact, preparing taxes and giving tax have become a big industry (工业)
in America.
