Abstract
Population III stars are now believed to contribute to the observed Near Infrared Background (NIRB) and heavy element pollution of the intergalactic medium. Here we show that a Pop III contribution to the primordial He abundance consistent with NIRB constraints, might mask a lower value for the Big Bang Nucleosynthesis (BBN) He abundance.
