Pure oxygen can be deadly. Our blood has evolved to capture the oxygen we breathe in and bind it safely to the transport molecule called haemoglobin. If you breathe air with a much higher than normal O2 concentration, the oxygen in the lungs overwhelms the blood's ability to carry it away.List of most-polluted cities by particulate matter concentration

Can we breathe 35% oxygen : The current partial pressure of oxygen in the atmosphere is 0.21 bar. Oxygen toxicity effects start to occur above 0.3 bar. So for an atmosphere that is 35% oxygen (by number) you'd need a total pressure of less than 0.86 bar to avoid toxicity effects.
