MIT Building Reopens After Dangerous Toxic Chemical Scare
An MIT student reportedly made a very dangerous chemical called dimethyl mercury.
The chemical can seriously poison people even in a tiny amount.
MIT closed a building because officials were worried about possible contamination.
Experts cleaned the student’s residence and other surfaces.
The student is being watched by doctors.
So far, blood tests have not found mercury exposure in the student.
Officials are not certain that the chemical was actually made.
MIT said the building was safe to reopen on August 31.
An MIT student reportedly synthesized dimethyl mercury without authorization on August 26.
MIT closed Building 18 after the compound’s reported synthesis and began specialized decontamination.
Dimethyl mercury is extremely toxic; OSHA says less than 0.1 millilitres can be a severely toxic dose.
The student remains under medical supervision, while blood tests have shown no mercury exposure.
MIT said residence-hall surfaces and individual units were decontaminated, allowing Building 18 to reopen on August 31.
