摘要: Sources of bias were examined in a study neurobehavioral effects intrauterine exposure to methyl mercury the Faroe Islands. The cohort 1000 children was born during 21-month period and did not differ from Faroese births general as regards major obstetrical parameters. However, high concentrations cord blood associated with increased birth weight, presumably because other constituents marine fish may cause prolongation gestation period. Thus, exposures somewhat protected against low weight its risks. Less than 25% women indicated occasional alcohol drinking pregnancy, thus suggesting limited fetal this risk factor. maternal caused decrease blood, probably toxicokinetic interaction between ethanol mercury. Any alcohol-related effect on development would then be lower levels exposures. these confounders tend results toward null hypothesis.
