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.

Studies comparing food additive intake and cancer showed that adverse health effects appeared when Acceptable Daily Intake (ADI) was exceeded. The review also detected a lack of studies on attention deficit-hyperactivity disorder. There were more studies on non-specific hypersensitivi...
