Editor's Notes

  1. 21-04-11 EP08163303 Use of clorine dioxide for removal of estrogenic substances in wastewater .
  2. 21-04-11 The relevance of estrogens is that they causes the cells to do something wrong. The cells or functions of the cells are not damaged as is seen with common toxicants that have effects like cytotoxicity or DNA-damage. In the water environment estrogens and estrogenic chemicals will stimulate the synthesis of vitellogenin in both young and adult of both sex. Vitellogenin is a protein that eggs are made from. In sexyal immature males estrogens may cause developement of feminine cell types. Sometimes full sex reversal is seen.
