Firstly, Thank you to everyone who recommended books on the lead mining history of Derbyshire. As part of my final year (BSc) I am carrying out a study concerning the movement of lead through trophic levels, looking in particular, at spoil tips in Derbyshire. I wondered if anyone could recommend (or has indeed written) any journals relating to this subject? I have found numerous studies carried out overseas but seem to be drawing a blank on journals relating to any studies carried out in the UK (especially Derbys) Can anyone help please? HAPPY NEW YEAR ALL!!! Trudi Dean _________________________________________________________________ Sign-up for a FREE BT Broadband connection today! http://www.msn.co.uk/specials/btbroadband
