MIT chemistry building remains closed after toxin spill

MIT's Camille Edouard Dreyfus Chemistry Building at 21 Ames Street, also known as Building 18, remains closed at least through Sunday while crews work to confirm it has been decontaminated after a Wednesday night spill involving dimethyl mercury, an extremely potent neurotoxin. MIT's Emergency Management department said Saturday that a single individual in a chemistry laboratory went to a local emergency room and said they had synthesized the substance; the student remains under medical supervision, though an initial blood test showed no signs of mercury exposure. An email to the chemistry department obtained by Cambridge Day said the student worked in the Wendlandt lab and that the dimethyl mercury was not part of any MIT research program.
