Occupational exposure:
BEI® (inorganic mercury, sampling time is preshift): 35 μg/g creatinine
Some organic forms of mercury, including phenylmercury, are metabolized to inorganic mercury; however, methylmercury and ethylmercury are not metabolized to inorganic mercury and the primary route of excretion is in the bile and stool; consequently, these alkylmercury compounds are usually not detected in urine.
