This means that, even for an individual, there is no threshold of dose below which there is absolutely no probability of an effect occurring, and the chance of experiencing the effect increases with increasing dose.","links":[{"term":"dose","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/DT06810"},{"term":"dose","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/DT07361"},{"term":"probability","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/P04855"}],"sources":["PAC, 2001, 73, 993.
