Derek Bryce-Smith{{cite web|title=University of Reading Staff Portal: Professor Derek Bryce-Smith|url=http://www.reading.ac.uk/internal/staffportal/news/articles/spsn-373484.aspx|access-date=1 September 2011}} (1926–2011) was an English chemist and professor of Organic Chemistry at the University of Reading from 1956 until his retirement in 1991. His work included organometallic chemistry, radical chemistry, photochemistry, environmental science, nutritional science and behavioural science. He was among the first to describe the dangers of tetraethyl lead, which was used for several decades as an anti-knock additive in petrol. Initially, his concerns were dismissed both by his fellow academics and by industrial interests.{{cite news|title=Derek Bryce-Smith obituary|url=https://www.theguardian.com/theguardian/2011/jul/19/derek-bryce-smith-obituary|access-date=1 September 2011|newspaper=The Guardian|date=19 July 2011}} However, by the time of his death, only six countries had not outlawed leaded petrol,{{cite news|title=Pollution: triumph of the inconvenient truth.

He subsequently became convinced that the use of NPK fertilisers in agriculture resulted in a lack of the essential trace element, zinc in modern (particularly vegetarian) diets; his pioneering views were again widely dismissed, becoming mainstream years later. An account of both campaigns is given in a book he co-authored with Liz Hodgkinson.
