Toxicity of Endocrine Disrupting Chemicals

Endocrine disrupting chemicals

The idea that xenobiotic chemicals could inappropriately modlate the endocrine system thereby causing detrimental effects n wildlife and humans was first proposed 20 years ago at the atershed Wingspread Conference [1,2]. These endocrine disruptng chemicals (EDCs) have long been controversial, with a great eal of discussion raging in the scientific literature. Much of this ontroversy has centere...

Cryptorchidism and endocrine disrupting chemicals

Prospective clinical studies have suggested that the rate of congenital cryptorchidism has increased since the 1950s. It has been hypothesized that this may be related to environmental factors. Testicular descent occurs in two phases controlled by Leydig cell-derived hormones insulin-like peptide 3 (INSL3) and testosterone. Disorders in fetal androgen production/action or suppression of Insl3 a...

Effects of Endocrine Disrupting Chemicals on Seals

At the same time harbour porpoises, that had died of a similar virus, appeared stranded on the beaches. Two years later another mass die-off occurred in the Mediterranean striped dolphin populations. The severe and lethal outcomes of the epidemics led many in the scientific community to believe that a contaminantinduced immune deficiency was responsible for the high mortality during the epidemi...

Risk Evaluation of Endocrine-Disrupting Chemicals

We review here our studies on early exposure to low doses of the estrogenic endocrine-disrupting chemical bisphenol A (BPA) on behavior and metabolism in CD-1 mice. Mice were exposed in utero from gestation day (GD) 11 to delivery (prenatal exposure) or via maternal milk from birth to postnatal day 7 (postnatal exposure) to 10 mg/kg body weight/d of BPA or no BPA (controls). Bisphenol A exposur...
