国家人类暴露评估调查（NHEXAS）/明尼苏达州儿童农药暴露研究（MNCPES）是一项基于人群的研究，旨在描述儿童接触住宅农药的特征，并评估住宅和儿童活动对儿童暴露的贡献。对168名儿童的家庭进行了调查，以了解农药的住宅使用情况和儿童活动情况。在这些家庭中，102名3至13岁儿童的家庭参加了为期一周的密集接触研究。在102名儿童中，19名儿童在正常的日常活动中连续四小时被录像。调查答复表明，最年幼的儿童更有可能表现出会促进暴露于环境污染物的行为。问卷调查结果的比较表明，录像的子样本是暴露研究人群的代表。对录像儿童的微活动进行了量化，这些微活动可能导致他们通过摄入或皮肤途径接触。手对嘴和物体对嘴的活动在最年幼的儿童中最常见。最小的孩子也最有可能在室内和室外赤脚。性别差异被发现在口的行为和观察的时间花费在户外的比例。
The National Human Exposure Assessment Survey (NHEXAS)/Minnesota Children's Pesticide Exposure Study (MNCPES) was a population-based study designed to characterize children's exposure to residential pesticides and to evaluate the contribution of residential and children's activities to children's exposure. Families of 168 children were surveyed for residential use of pesticides and children's activities. From these homes, families of 102 children between the ages of 3 and 13 years participated in a week-long intensive exposure study. Of the 102 children, 19 children were videotaped for four consecutive hours in their normal daily activities. The survey responses indicated that the youngest children were more likely to exhibit behaviors that would foster exposure to environmental contaminants. Comparison of questionnaire responses indicated that the videotaped subsample was representative of the exposure study population. The microactivities of the videotaped children that might contribute to their exposure via ingestion or dermal routes were quantified. Hand-to-mouth and object-to-mouth activities were observed most frequently among the youngest children. The youngest children were also most likely to be barefoot both indoors and outside. Gender differences were found in mouthing behavior and the proportion of observed time spent outdoors.
