We investigated the biological half-life of urinary cadmium concentration (U-Cd) based on a 24-year follow-up study after cessation exposure in cadmium-polluted area. Spot urine samples were obtained from all inhabitants this area 1979, 1986, 1991, 1999 and 2003. Biological was calculated whose U-Cd more than 5 microg l(-1) (9 men 12 women) or g(-1) creatinine 19 using one-compartment model. The estimated 95% confidence intervals 13.6 years (9.0-28.2 years) 13.9 (9.6-25.6 for unadjusted...

Objective: This study investigated the effect of alternating shift work (ASW) on onset diabetes mellitus in Japanese workers compared with day-shift (DSW). Methods: A longitudinal was carried out a DSW group (n = 3203) and ASW 2426) steel company who received their annual health checkups over 10-year period between 1991 2001. The association job schedule type (glycated hemoglobin A1c ≥6.0% or medication) by multivariate pooled logistic regression analyses. Results: odds ratio (95% confidence...

Dioxin levels in the breast milk of mothers residing near hot spots dioxin contamination areas South Vietnam remain much higher than unsprayed areas, suggesting that fetuses and breast-fed infants may be exposed to high dioxins. The present study investigated association infant neurodevelopment early infancy exposure during perinatal period.The involved 216 mother-infant pairs living Da Nang airbase, a contaminated area Vietnam. Mothers were followed from birth until 4 months old. measured...

A multiple logistic analysis used adjusting base-line characteristics such as age, body mass index, pressure, drinking habit.In younger age group, relative risk...

Abstract The reversibility of β2-microglobulinuria, glucosuria, and aminoaciduria was examined in 74 inhabitants (32 males 42 females) over 50 yr age, who lived a cadmium-polluted area. subjects participated two examinations conducted just after the cessation cadmium exposure 5 later. All urinary parameters did not show reversible changes. During geometric mean concentrations indicated significant increases excretion. In cases where > 1,000 μg/g creatinine β2-microglobulinuria observed (at...

In an operation by United States Armed Forces during 1961 to 1971, large quantities of herbicides were sprayed in South Vietnam. These contained 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-tetraCDD), the most toxic congener dioxins. Several decades after herbicide spraying ceased, dioxin concentrations environment and human remained elevated areas. Breast milk samples from 520 nursing mothers residing areas including hot spots as well unsprayed collected quantify levels The total...

Dioxin exposure levels remain elevated in residents living around former US Air Force bases Vietnam, indicating potential adverse impacts on infant growth. In this study, 210 mother–infant pairs dioxin-contaminated areas Vietnam were recruited at the infants' birth and followed up for 4 months.
