Element abundances measured in five PG 1159 stars. Upper limits are indicated by arrows. Data for our two program stars and PG 1159−035 are from Table 1. Data for PG 1707+427 and PG 1424+535 are from Werner et al. (2015) except for the H abundances (from Werner et al. 1991). The black solid line indicates solar abundances.
