The neurobehavioral status was tested for 92 matched-pair pupils aged 11-13 in an area with high-level-manganese sewage irrigation and a control area. Results showed there was significant difference in manganese contents of drinking water between the area with sewage irrigation and the control area during 1990-1992, ranged 0.241-0.346 mg/L and 0.030-0.040 mg/L, respectively, with P < 0.01. Hair manganese content of children in the area with sewage irrigation (1.252 micrograms/g) was significantly higher than that in the control area (0.961 micrograms/g) with P < 0.01. Scores in digit span, Santa Ana manual dexterity, digit symbol, Benton visual retention test and pursuit aiming test for children in the area with sewage irrigation were significantly lower than those in the control area (P < 0.01). Hair manganese contents of the children in the area with sewage irrigation correlated negatively with most of those scores. It suggested high level of manganese in drinking water of the area with sewage irrigation might be an important factor affecting children's neurobehavioral changes.
对某高锰污水灌溉区和一个对照区的92名年龄在11至13岁的匹配对学生进行了神经行为状态测试。结果显示，1990 - 1992年期间，污水灌溉区与对照区饮用水中的锰含量存在显著差异，分别为0.241 - 0.346毫克/升和0.030 - 0.040毫克/升，P < 0.01。污水灌溉区儿童的发锰含量（1.252微克/克）显著高于对照区（0.961微克/克），P < 0.01。污水灌溉区儿童在数字广度、圣安娜手动敏捷性、数字符号、本顿视觉保持测试和追踪瞄准测试中的得分显著低于对照区（P < 0.01）。污水灌溉区儿童的发锰含量与其中大多数得分呈负相关。这表明污水灌溉区饮用水中的高含量锰可能是影响儿童神经行为变化的一个重要因素。
