Take your own here and learn something new and perhaps surprising! Some of the metabolites also leave the body in the air you breathe out. Even when the person recovers, they may have symptoms like disorientation, vomiting, headache etc. When ingested, chloroform is converted into a chemical called phosgene. WebChloroform is a dense, sweet-smelling, organic liquid that acts as a strong anesthetic, euphoriant, anxiolytic, and sedative if inhaled or ingested; miscible and relatively unreactive with most organic liquids; used as a lab solvent, reagent, anesthetic, etc. Eyes and skin exposed to chloroform should be washed and rinsed with clean, uncontaminated water. #fca_qc_quiz_41911.fca_qc_quiz p:not( .fca_qc_back_response ):not( #fca_qc_question_right_or_wrong ):not( .fca_qc_question_response_correct_answer ):not( .fca_qc_question_response_response ):not( .fca_qc_question_response_hint ):not( .fca_qc_question_response_item p ), Biodegradation in water and soil is slow. For good reason, chloroform is no longer used as an anesthetic; it is a difficult task to determine the right dose that would render a person unconscious without affecting other vital nerve functions. It is also a precursor to various refrigerants. Glover also undertook practical experiments on dogs to prove his theories. Phosgene reacts with water to form carbon dioxide and HCl,[63] and the carbonate salt neutralizes the resulting acid. This Public Health Statement is the summary chapter from the Toxicological Profile for chloroform.
