In the [[biology|biological sciences]], accidental introduction of "foreign" material can seriously distort the results of experiments where small samples are used. In cases where the contaminant is a living [[microorganism]], it can often multiply to dominate the sample and render it useless, as in [[List of contaminated cell lines|contaminated cell culture lines]]. A similar affect can be seen in [[geology]], [[geochemistry]], and [[archaeology]], where even a few grains of a material can distort results of sophisticated experiments.<ref name="AbzalovApplied16">{{cite book |url=https://books.google.com/books?id=Oy3RDAAAQBAJ&pg=PA387 |title=Applied Mining Geology |author=Abzalov, M. |publisher=Springer |page=387 |year=2016 |isbn=9783319392646 |access-date=2019-04-12 |archive-date=2020-08-07 |archive-url=https://web.archive.org/web/20200807052437/https://books.google.com/books?id=Oy3RDAAAQBAJ&pg=PA387 |url-status=live }}</ref>
