We have conducted a battery of anthropometric measures, a detailed assessment of neurobehavioral development, quantification of acetylcholinesterase activity and other pesticide exposure measures, assayed hormone levels, collected and stored samples for biomarker assessments, and collected geospatial information of homes and flower plantations in the county. Additionally, we conducted in-person surveys of parents and floricultural workers.
