摘要: Nitrate contamination in groundwater is a worldwide problem especially agricultural countries. Environmental factors, such as land-use pattern, type of aquifer, and soil-drainage capacity, affect the level contamination. Exposure to high levels nitrate may contribute adverse health effects among residents who use for consumption. This study aimed determine relationship between with Photharam District, Ratchaburi Province, lower Mae Klong basin, Thailand. Health risk maps were created based on hazard quotient quantify potential using US Protection Agency (U.S. EPA) assessment model. The results showed influence patterns, capacity It was found that most studied area not at risk; however, monitoring system should be implemented.
