Is this a joke about toxicity/chemistry or is the field of chemistry known to be socially more toxic than other fields?

> Eight graduate students have committed suicide at Harvard since 1980, officials said -- not an unusual rate for a university. > Of those, three have been in the laboratory of Mr. Altom's adviser, Elias J. Corey, a Nobel Prize-winning chemist. > But Dr. Long asserted today that by all indications, the first two deaths, one last year and one in 1987, had nothing to do with the students' work in chemistry. > One student, he noted, had been very successful in his work, and the other had barely begun.
