The hardest part (of the research) is that it's done outside under natural conditions that are changing all the time,

All around us, we see plants that have endured chronic ozone exposure with no apparent adverse symptoms except premature aging and reduced reproduction, ... Could this relate to the human experience? That's what we need to find out. But, in the meantime, it's important for us to determine how ozone exposure affects our forests, our wetlands, our crops, and even our backyards.

Most people think our breathable air is getting cleaner, and it is in some areas, ... We have fewer days of extremely bad air, thanks to clean air acts. But steady, day-to-day exposure to pollutants, especially ozone, is becoming more prevalent. On bad days, some plants are getting ozone at concentrations of 60 to 80 parts per billion.
