Limitations

Blood mercury levels may be elevated due to the presence of inorganic mercury and/or organic mercury compound (e.g., ethylmercury and methylmercury). These alkylmercury compounds are generally not used in industry but are considered more toxic to humans than inorganic mercury.

Blood levels of arsenic have a short half-life and are useful only for monitoring recent or acute exposure. Urine arsenic measurement is a better measure of arsenic poisoning.
