TL;DR: The effects on brain function associated with prenatal methylmercury exposure therefore appear widespread, and early dysfunction is detectable at exposure levels currently considered safe.
Journal Article
[Production of the Japanese edition of profile of mood states (POMS): assessment of reliability and validity].
TL;DR: The POMS (Profile of Mood States) was translated into Japanese, and reliability and validity of the Japanese edition was assessed on 354 healthy males, indicating that the POMs had good criterion-related validity, except for "Anger-Hostility".
Journal ArticleDOI
Subclinical neurophysiological effects of lead: A review on peripheral, central, and autonomic nervous system effects in lead workers.
TL;DR: An overview of research addressing subclinical neurophysiological effects of lead in workers exposed to lead is presented and it is suggested that, on a group basis, the reduction in the NCV, together with the effects on the P300 latency, postural balance, and CV(RR), occurs at a mean blood lead concentration as low as 30-40 microg/dL.

Mohsen Vigeh,Kazuhito Yokoyama,Fateme Ramezanzadeh,Mojgan Dahaghin,Tadashi Sakai,Yoko Morita,Fumihiko Kitamura,Hajime Sato,Yasuki Kobayashi +8 more
TL;DR: Environmental exposure to Pb, Sb and Mn may increase the risk of preeclampsia in women without occupational exposure; levels of metals in UCB to be sensitive indicators of female reproductive toxicity as compared with those in mother MWB.
