Does detection of polycyclic aromatic hydrocarbon exposure from automobile exhaust fume using urinary 1-hydroxypyrene level as an index?
Automobile exhaust fume exposed subjects have a higher risk to be exposed to PAHs than the non-exposed subjects. Urinary 1-hydroxypyrene level can be used as an index for an exposure of PAHs which have originated from automobile exhaust fumes and other sources as well.
Although C(t-45) is useful to estimate Kt/V when assessing mean values, it is not suitable when assessing patients individually. This study demonstrates that the best method to calculate equilibrated Kt/V was a blood sample for urea concentrations 30 min after haemodialysis.
