1. Aerosol particles act as CCNs creating more droplets of a smaller size.2. Aerosol particles are eventually deposited from the stratosphere onto land and ocean.3. The gaseous compounds may be adsorbed on the surface of the aerosol particles . 4. A high proportion of aerosol particles originate from the reactor control rod materials. 5. As a result, aerosol particles are usually observed as agglomerates rather than individual particles. 6. The aerosol particles form a whitish haze in the sky. 7. Clouds are created when water vapor condenses on tiny aerosol particles to form droplets. 8. Powder-based aerosol particles can pose advert effects when deposited in human respiratory systems via inhalation. 9. Gases preferentially condense onto surfaces of pre-existing aerosol particles , known as "'heterogeneous nucleation " '. 10. Aerosol particles can act as CCN's creating more droplets which have a smaller size distribution.
