===Hair data analysis===
In this project, three important comparisons of experimental data were made. These three comparisons are related to glass test, quartz test and the comparison of glass and quartz test results.
In the comparison of the experimental data of glass plate test, the relative values of element content for lead, mercury, arsenic and cadmium in Somerton man’s hair are significantly higher than control samples in certain period of time. However, these elements’ content have been reduced to a safe range before his death. Thus the high content of these elements cannot be regarded as the main cause of Somerton man’s death, only as a reference to the change of living environment.
In the comparison for the data of quartz test, the total amount of recorded elements were reduced from 44 in glass test to 35 which is due to the high purity of quartz plate. Thus, some elements in glass test are excluded. Through comparison, the content of carbon and sulphur in Somerton man’s hair has a large difference with the fourth sample. In addition, the content of potassium, strontium and calcium are similar with the first sample. Therefore, it can assume that Somerton man’s living area is different with the fourth sample, but similar with the first sample.
The data comparison between glass and quartz test does not achieve the desired results. So, the experimental method may need to change in the future work.
