Geochemistry of an arsenic anomaly in ST. Elizabeth, Jamaica

摘要

A soil arsenic anomaly with concentrations up to 400 μg As g~-1 was discovered near Maggotty, St. Elizabeth, during an island-wide geochemical survey of Jamaica. Detailed sampling And chemical analysis of soil samples confirmed the arsenic levels and led to a better definition of The size of the anomaly. The area exceeding the 95th percentile (＞65μg As g~-1) of the island-wide Concentrations has been determined to be at least 10 km~2.
