Even if he did, he certainly didn’t have toxicology in mind. But the concept is very relevant to toxicology, especially these days when substances can be detected at the part per trillion level. How small is a part per trillion? That would be 1 cent in 10 million dollars or one second in 32,000 years, which is longer than human civilization.</p> Wed, 01 Mar 2023 21:22:38 +0000 Joe Schwarcz PhD 9418 at /oss
