Few studies were available to evaluate the temporal change of mirex in bird samples. The only studies of mirex in seabird eggs were conducted by Braune et al. (2001) on the temporal trends from 1975 to 1998 in the Canadian Arctic. A decreased trend of mirex levels was only observed in eggs of black-legged kittiwakes but not in northern fulmars and thickbilled murres. The levels of mirex that were measured in the eggs of the studied animals ranged from 0.003 to 0.013 pg g-1 wet wt. in 1998. There did not appear to be any consistent change in the proportions over the study period (Braune et al., 2001). No information is available on the level of mirex in waterbirds in China. 

There were declining trends of the total DDT// ,//-DDE residues in seabird eggs in the Canadian Arctic and the Alaskan Arctic. The levels of total DDT in the eggs of black-legged kittiwakes, northern fulmars and thick-billed murres that were collected in the Canadian Arctic reduced from 1975 to 1998 (Braune et al., 2001).

A l,l -dimethyl-2,2 -bipyrrole with four bromines and two chlorines has been isolated and identified in various seabird egg samples from Canada. The precise substitution pattern was not established (99EST26). 5,5 -dichloro-l,l -dimethyl-3,3, 4,4 -tetrabromo-2,2 -bipyrrole (Br4Cl2-DBP) was prepared and identified in Tiger Sharks (09EST2288), in various whale products in Japan (06MI135) and California sea lions (06MI522).
