Because this outcome parameter appeared to be virtually independent of confounders, including cultural differences, a joint analysis of benchmark doses was carried out. Comparable cohort members included 382 Faroese and 113 Madeiran children without middle ear infection or neurological disease at age seven years. Maternal hair\u2010mercury concentrations at parturition in the Faroese cohort ranged from 0.6 to 39.1 \u03bcg\/g (geometric average, 4.49 \u03bcg\/g). In Madeira, mothers who had not changed their diet since pregnancy had current hair\u2010mercury concentrations ranging from 1.1 to 54.4 \u03bcg\/g (geometric average 10.14 \u03bcg\/g). The mercury\u2010associated delay in peak III latencies at two frequencies (20 and 40 Hz) showed similar regression equations in the two groups of children, and benchmark dose calculations were therefore carried out for the two groups separately and jointly. For a doubling of a 5% prevalence of abnormal results of the peak III latencies at 40 Hz in a linear dose\u2010response model, the benchmark dose for the maternal hair\u2010mercury concentration was 8.79 \u03bcg\/g for the Faroese children; 8.04 \u03bcg\/g for the Madeiran children; and 9.46 \u03bcg\/g for both groups. Results were similar for the 20 Hz condition. Benchmark dose results were substantially lower using a logarithmic or square root curve function, although the difference in fit between the curves was far from statistically significant. The benchmark results using evoked potential latencies are in close agreement with results based on neuropsychological test performance.<\/jats:p>","DOI":"10.1111\/0272-4332.00034","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T14:25:03Z","timestamp":1047479103000},"page":"465-474","source":"Crossref","is-referenced-by-count":43,"title":["Benchmark Dose Calculations for Methylmercury\u2010Associated Delays on Evoked Potential Latencies in Two Cohorts of Children"],"prefix":"10.1111","volume":"22","author":[{"given":"Katsuyuki","family":"Murata","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Esben","family":"Budtz\u2010J\u00f8rgensen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Grandjean","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2002,7,22]]},"reference":[{"key":"e_1_2_6_2_2","volume-title":"Methylmercury","author":"International Programme on Chemical Safety","year":"1990"},{"key":"e_1_2_6_3_2","volume-title":"Toxicological Effects of methylmercury.","author":"National Research Council","year":"2000"},{"key":"e_1_2_6_4_2","volume-title":"Mercury Study Report to Congress","author":"U.S. Environmental Protection Agency (EPA)","year":"1997"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.32.12.1369"},{"key":"e_1_2_6_6_2","first-page":"282","article-title":"Auditory brainstem responses in fetal organic mercury poisoning (in Japanese)","volume":"16","author":"Hamada R","year":"1982","journal-title":"Shinkei-Naika"},{"key":"e_1_2_6_7_2","first-page":"48","article-title":"Electrophysiological studies on Minamata disease (in Japanese)","volume":"16","author":"Inayoshi S.","year":"1988","journal-title":"Japanese Journal of EEG & EMG"},{"key":"e_1_2_6_8_2","first-page":"588","article-title":"Brainstem and middle auditory evoked potentials in Minamata disease (in Japanese)","volume":"35","author":"Inayoshi S.","year":"1993","journal-title":"Clinical Encephalography"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003446-199906000-00009"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1006\/enrs.1993.1135"},{"key":"e_1_2_6_11_2","first-page":"185","article-title":"Blood mercury and auditory neuro\u2010sensory responses in children and adults in the Nambija gold mining area of Ecuador","volume":"19","author":"Counter S.
