Determination of arsenic poisoning and metabolism in hair by synchrotron radiation: the case of Phar Lap.

The research investigates the potential cause of death of Phar Lap, Australia’s legendary racehorse, using synchrotron radiation to analyze his hair for evidence of arsenic poisoning and metabolism.

About Phar Lap and His Mysterious Death

• Phar Lap was a well-known racehorse from Australia who unfortunately died under suspicious circumstances in 1932 after claiming victory at the Agua Caliente Handicap in Mexico, which was regarded as the world’s richest race at the time.
• Despite the horse’s notable record of winning 32 out of his last 35 starts, Phar Lap’s popularity was controversial, leading to a failed drive-by shooting attempt on him.
• After his sudden and painful death in California, theories about the cause of his death ranged from intentional poisoning, overdosing on tonics, colic, and a previously unknown form of bacterial gastroenteritis.
• The lack of a conclusive post-mortem examination left the cause of death open to speculation.

Arsenic Poisoning Investigation Using Synchrotron Radiation on Phar Lap’s Hair

• Given the unsolved nature of Phar Lap’s cause of death, the researchers in this study explored the possibility of retrieving evidence of arsenic poisoning from Phar Lap’s preserved strands of hair.
• The study is premised on the idea that as hair grows, it incorporates foreign substances from the blood supply into its structure, creating a sort of ‘chronological record’ of the individual’s health and environmental exposures.
• The use of synchrotron radiation allows for a higher degree of precision and detail when analyzing the hair structure.
• By examining the concentrations and distribution of arsenic in Phar Lap’s hair, they hoped to not only determine if the horse was indeed poisoned but also understand how the horse metabolized this potential poison over time.
• Evidence of arsenic poisoning could provide conclusive proof as to one of the speculated causes of Phar Lap’s mysterious death.

Significance and Impact of Findings

• Determining the cause of Phar Lap’s death through such an innovative method would certainly shed new light on one of sport’s most enduring mysteries.
• Furthermore, integrating the usage of synchrotron radiation into investigations of poisoning could potentially deepen our understanding of how toxins interact with biological organisms and how these toxins are metabolized over time.
• Such an approach can provide invaluable insight for forensics and toxinology, pushing the boundaries of how we uncover and interpret complex biological mysteries.
