Science Exchange Wallingford: Sex Hormones in the Water  – Andrew Johnson, Centre for Ecology and Hydrology. Tuesday 6th March 2018

From the Science Exchange Wallingford: Sex Hormones in the Water a talk by Andrew Johnson, Centre for Ecology and Hydrology. Tuesday 6th March 2018, Wallingford School Library 

  • Back in the 1990s it was noticed that male fish living in proximity to sewage effluent in our rivers were showing signs of changing sex.  These male fish were developing female characteristics such as the presence of eggs in the testes.  This phenomenon was most closely associated with the escape of human excreted estrogens, both natural and synthetic, from sewage treatment plants.  At the same time, concerns over human health developed with the concept of the ‘testicular dysgenesis syndrome’ being raised which included issues liking declining sperm counts.  The talk will discuss how these topics developed and where we are now.
  • Andrew Johnson is an environmental scientist employed as a Principal Scientific Officer at the NERC Centre for Ecology and Hydrology in Crowmarsh Gifford.  In addition, he is a Visiting Professor at Brunel and Kyoto Universities.  He is also a member of the Defra Hazardous Substances Advisory Committee
  • Science Exchange Wallingford’s next meeting is at 7.30pm on Tuesday 6th March in Wallingford School Library, St George’s Road, Wallingford.  Meetings are very informal. Speakers talk for about half an hour, then we break for refreshments and return for a lively question and answer session.  We are grateful that the support of local company Triaster, Wallingford School and the generosity of our speakers ensures that each event is free to attend.  We are also privileged to be a Café Scientifique.  (

World War One Memorial Ceremony -30 November, 4 December and 8 December at 11am

Now we are into the last year of our centenary ceremonies and having only just commemorated the loss of Lance Corporal Edward Hutt, we sadly now have three more in quick succession:
· Private Ernest Cook on the 30th November
· Pioneer Frank Beale on the 4th December; and
· Private Bernard Belcher on the 8th December.
As always, any are welcome and we will congregate in the lobby of the Pavilion moments beforehand. We had one of our largest ever turn-outs for Edward Hutt, including two of his relatives (his great nieces) who both still live in the village.
