Lead isotopic ratio determination is significantly affected by the isobaric interference of mercury ( 204 Hg), thus many studies lack 204 Pb/ 206 Pb values. Removal of 204 Hg from sample is resource consuming, while mathematical correction can be employed if the Hg isotope ratio in the sample is known. Triple quadrupole inductively coupled plasma mass spectrometry (TQ-ICP-MS) offers a mechanism for removing the 204 Hg, by pressurizing the reaction cell with ammonia, that reacts with 204 Hg

The Pb isotope ratio determination can be used as "fingerprint" to identify the sources of contamination and environmental pollution. The method developed based on this mechanism was used for Pb isotopic ratio determination in cave sediment samples. Relative standard deviation of this method was between 0.36% -0.59%.
