Results: The content of Al was 0.0147±0.0022 mg/L in drinking water, 395.3 mg/kg in sweet potato noodle, 860.7~1012.1 mg/kg in fried bread stick, and that dissolved from cooking utensils made of aluminum is becoming great after being stored for 24 hours.

结果：生活饮用水铝含量为0.0147±0.0022 mg/L；食品中油条、粉条铝含量较高，特别是油条中铝含量平均为860.7 mg/L，最高达1012.1 mg/kg，粉条中铝含量高达395.3 mg/kg；铝制炊具铝溶出量测定结果显示，符合卫生标准的饮用水在铝制炊具中存放24 h后，水中铝含量即会超标。

Fluorine is one of crucial chemical elements to human health and can be tested in almost every parts of a healthy human body. Overloading of fluorine may cause dental and/or skeletal fluorosis, while in fluorine deficiency areas, fluoride drinking water supply or other methods of fluoridation may greatly reduce the ratio of dental caries of local residents. Researches on relation between fluorine concentration in drinking water and the ratio of human dental caries as well as the evaluation on efficacy of drinking water fluoridation have been lasted for 6 decades.
