Generally this site will satisfy that type of research:
http://www.airfleets.net/home/
However the F28 isn't listed specifically. It is possible there aren't any in use for commercial passengers today. See this 2012 post from a well-known pilot's bulletin board: http://www.pprune.org/questions/4844...ll-flying.html
This site indicated there were 14 of 241 built still flying late in May 2015. The type of service they were in is unclear: https://www.flightglobal.com/news/ar...l-jets-412225/
