MIT Student Claims Toxin Synthesis; Hazmat Alert Issued
30 Aug
Summary
- Student claimed to have synthesized highly toxic dimethyl mercury.
- MIT's Building 18 was closed for assessment and decontamination.
- Initial tests show no mercury exposure for the student.

A hazmat response was initiated at MIT after a graduate student claimed to have synthesized dimethyl mercury in a campus laboratory. The student reportedly made the claim after seeking medical attention. This led to the closure of Building 18, a chemistry facility, for assessment and decontamination.
MIT officials stated the student was not authorized to work with the hazardous chemical and it was not part of their research. Dimethyl mercury is extremely toxic and can be absorbed through the skin, posing significant health risks.
Emerging information has cast doubt on whether the compound was actually synthesized. The university confirmed, with the student's permission, that initial blood tests show no sign of mercury exposure. The student remains under medical supervision.
MIT has contacted individuals who may have been in proximity to the student or laboratory. While the situation is being investigated, officials believe the risk of exposure is very low.
