Published mixtures data and a human health risk assessment for phthalates and anti-androgens were evaluated to determine how firmly the DA–CAOS concept is supported and with what level of statistical certainty the results may be extrapolated to lower doses in humans. Underlying assumptions of the DA–CAOS concept were tested for accuracy and consistency against data for two human pharmaceuticals and its logical predictions were compared to human clinical and epidemiological experience. Those analyses revealed that DA–CAOS is scientifically untenable. Therefore, an alternative approach was developed – the Human-Relevant Potency-Threshold (HRPT) – that appears to fit the data better and avoids the contradictions inherent in the DA–CAOS concept. The proposed approach recommends application of independent action for phthalates and other chemicals with potential anti-androgenic properties at current human exposure levels.</dcterms:abstract> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2012-07-26T06:42:30Z</dc:date> <dc:creator>Golden, Robert J.</dc:creator> <dc:rights>deposit-license</dc:rights> <dcterms:issued>2012-03</dcterms:issued> <dc:creator>Sargent, Edward V.</dc:creator> <dc:contributor>Borgert, Cristopher J.</dc:contributor> <dc:contributor>Casella, George</dc:contributor> <dc:contributor>Sargent, Edward V.</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Regulatory Toxicology and Pharmacology ; 62 (2012), 2. - pp. 313-328</dcterms:bibliographicCitation> <dc:contributor>Golden, Robert J.</dc:contributor> <dc:contributor>Dietrich, Daniel</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2012-07-26T06:42:30Z</dcterms:available> <dc:creator>Dietrich, Daniel</dc:creator> <dc:creator>Casella, George</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/19842"/> </rdf:Description> </rdf:RDF>
