At the 7th Torino workshop held at the IoA, Cambridge University, in August 2004, a brief overview was given about the galactic globular cluster abundance anomalies problem, followed by a short report on our test of the popular theory that the observed abundance anomalies in the Galactic globular cluster NGC 6752 are due to `internal pollution' from intermediate mass asymptotic giant branch stars. In the test we use a chemical evolution model to track the composition of the intracluster medium over time. Custom-made stellar evolution models were calculated using the Monash/Mount Stromlo stellar structure code and the Monash nucleosynthesis code. Yields from these calculations were used as feedback in the chemical evolution model. A novelty of this study is that the stellar evolution of the second generation stars was calculated using the appropriate composition (non scaled-solar), as given by the chemical evolution model. By tracing the chemical evolution of the intracluster gas we are able to test the internal pollution scenario, in which the Na- and Al-enhanced ejecta from intermediate mass AGB stars is either accreted onto the surfaces of other stars, or goes toward forming new stars.
