Integrated Water Resource Management for Important Deep European Lakes and their Catchment Areas EUROLAKES D10: Impact of Contaminants ANNEX 1 Schemata with the mode of action of endocrine disrupters FP5_Contract No.: EVK1-CT1999-00004 Version: 4.0 Date: 25/07/01 File: D10-vers.4.0.doc Page 131 of 136 Cells have receptors where hormones are able to tie down. The hormone-receptor-complex is activating the cell. Natural hormones dock at receptors and activates it in the appropriate level [WWF CANADA, DEVITT 1997]. Endocrine disrupters are able to dock at the receptor, too. They are blocking normal signals because the body hormones can not fit into the receptor. Hormone blockers interferes with the signal from the body hormones [WWF CANADA, DEVITT 1997]. The messages send by the endocrine disrupters are wrong. Either they give a signal stronger than the body's hormone (and at the wrong time), or... endocrine disrupter gives a signal weaker than natural hormones and at the wrong time [WWF CANADA, DEVITT 1997].
