    • Summary of Total Mercury Concentrations in Dragonfly Larvae, Western Mosquitofish, and Tree Swallow Eggs Collected from Cosumnes River Preserve 2011 – 2013

    Metadata Updated: October 30, 2025

    The Cosumnes River Preserve in the California’s Central Valley contains a mosaic of managed wetlands where conditions may promote high levels of methylmercury bioaccumulation. In order to document potential environmental health risk in these wetlands due to mercury, we analyzed dragonfly larvae, western mosquitofish, and tree swallow eggs collected from wetlands and rice fields of the Preserve from 2011 to 2013.
