In the present study we used a photochemical reaction chamber to generate particle-free urban-like multipollutant mixtures for the purpose of evaluating the pulmonary and cardiac responses in mice to inhalation of an atmosphere containing complex multipollutant mixtures or [O.sub.3] at the same concentration as present in the multipollutant mixtures.
In original photochemical reactions, as the electron donor, the excited RC pigments transfer the electrons to electron acceptor to realize the charge separation and then leave behind "holes".
