Abstract
High concentrations (ppm) of 2,4‐dichlorobenzoic acid was found in water collected in percolation Iysimeters during a soil project on heathland soils in Denmark. To trace if the source was lysimeter materials a laboratory experiment was set up. In this plastic materials used in the lysimeter construction were exposed to topsoil from the heather area. The experiment showed that 2,4‐dichlorobenzoic acid was released from silicone tubes placed in contact with natural soil and rainwater. The compound is probably a transformation product from bis (2,4‐dichlorobenzoyl)peroxide used in production of silicone rubber.
