New particle formation (NPF) has been expected to be less favored in the polluted atmosphere than in the clean atmosphere. However, highly polluted regions in developing countries like China and India are becoming hot spots of NPF. Understanding nucleation and growth mechanisms of aerosol particles in polluted environments have important implications in their global climate impact and health effect. This paper reviewed recent publications from atmospheric field and laboratory measurements under conditions relevant to the polluted atmosphere. NPF probability in polluted environments was discussed by exploring the uncertainties in coagulation sink and growth rate estimations. Future directions and challenges in understanding NPF in highly polluted environments are presented.
