5-hydroxy-N- methyl-2-pyrrolidone (5-HNMP) and 2-hydroxy-N- methylsuccinimide (2-HMSI) have been measured in the urine and blood of exposed workers and volunteers in several studies. The results compared well with air levels of NMP. The use of urine and blood tests for monitoring workplace exposure to NMP is still being studied.
