Abstract
Toxic organic compounds, such as pesticides, pharmaceuticals, explosives, chlorine disinfection byproducts, petroleum hydrocarbons, and chlorinated solvents have found their way to wetlands from diverse sources, including agricultural and urban runoff, domestic wastewater effluent, and industrial discharges. Evaluations of the fate and ecological effects of these compounds in wetlands depends on accurate and precise methods to determine the concentrations in each of the wetland compartments, including surface water, pore water, soils, and sediments. This can be particularly challenging due to water saturation, low redox conditions, accumulation of organic matter, and reduced S compounds in wetlands, which can complicate and interfere with many of the analytical steps. The goal of this chapter is to summarize and briefly describe the methods that have been used to collect, preserve, extract, analyze, and calculate the concentrations of a multitude of volatile organic compounds and semivolatile organic compounds in the surface water, pore water, and soils and sediments of wetlands.
