Abstract : Accreting matter around black holes can flow to the central object, in various modes. Various models of accretion discs are discussed in this talk. Out of these the advective discs are trans-relativistic in nature and can be quite hot. We study various methods by which particles can be created in these discs and show that pair production can be significant in flows at distance of few Schwarzschild radii from the central hole. These are the regions which are supposed to launch the jets, and therefore these new particles may contaminate the external environment.
