Thirty-three hours of videotape collected in a 1993 pilot study were quantified, via a video translation software application, to obtain left and right hand activity data of four children of farmworkers. Reported here are the children's contact duration and frequency for each object in their environment, duration spent in each location and activity exertion level, and frequency distributions of object contact durations. The pilot study provided valuable information for evaluating and improving videotaping and videotape translation methodologies as a means of gathering activity information that can be used to refine dermal exposure estimates. Although a larger database of children's videotaped activities for different ages and populations is needed before generalizations can be made, the data presented here are the most detailed information to date for children's micro-level dermal activities.
通过一个视频翻译软件应用程序，对1993年一项试点研究中收集的33小时录像带进行了量化，以获取4名农场工人子女的左右手活动数据。本文报告了这些儿童与周围环境中每个物体的接触时长和频率、在每个地点停留的时长和活动 exertion 水平，以及物体接触时长的频率分布。该试点研究为评估和改进录像及录像带翻译方法提供了有价值的信息，这些方法可作为收集活动信息的手段，用于完善皮肤暴露估计。尽管在能够进行概括之前，需要针对不同年龄和人群建立更大的儿童录像活动数据库，但此处呈现的数据是迄今为止关于儿童微观层面皮肤活动的最详细信息。
