In this paper, we show that for a connected compact Lie group to be acceptable, it is necessary and sufficient its derived subgroup isomorphic direct product of the groups $${\text {SU}}(n)$$ , {Sp}}(n)$$ {SO}}(2n+1)$$ {G}}_2$$ {SO}}(4)$$ . We there are invariant functions on {SO}}_{4}({\mathbb {C}})^{2}$$ which not generated by 1-argument invariants, though {C}})$$ acceptable.

Some phthalates are developmental and reproductive toxicants in animals. Exposure to phthalates is considered to be potentially harmful to human health as well. Based on a comprehensive literature research, we present an overview of the sources of human phthalate exposure and results of exposure assessments with special focus on human biomonitoring data.
