We reconsider the Poland and Scheraga model for the DNA denaturation transition taking into account environmental effects. Here, we apply field theoretical methods to discuss environmental effects on the nature of the transition. In particular we discuss variants of the transition that may occur due to particular properties of the environment. These are the presence of uncorrelated and power-law long-range correlated disorder which influence the transition as function of the power law exponent, the quality of the solution which may affect the self and mutual interaction of both single and double strands and combinations of these. We show that all of these have significant effects on the transition.
