The half-lives in humans for the lower brominated PBDEs (tetraBDEs through pentaBDEs) may be longer because an increase in half-life was observed with decreasing bromination degree for decaBDE, octaBDE, and hexaBDE (Jakobsson et al.
By analogy to other persistent organic pollutants (POPs), it is likely that relative absorption may decrease at high concentrations; that the higher the degree of bromination, the poorer the absorption; that oral absorption will be similar to pulmonary absorption; and that dermal absorption will be quite limited.
