Abstract

INTRODUCTION Heavy metals in the environment can appear as residues in foodstuffs. (1) They can be harmful for humans because they are not metabolized, and thus, they accumulate in the [...], BACKGROUND: Controlling for day-to-day variation is a key issue in estimating long-term dietary exposure to heavy metals using 24-hour recall (24HR) data from a relatively small number of days. OBJECTIVES: This study was conducted to estimate long-term dietary exposure to lead, cadmium and mercury among Korean children using the Iowa State University (ISU) method and to assess the contributions of different food groups to heavy metal intake. METHODS: We analyzed 2 days of 24HR data from 457 children between 0 and 6 years of age in 2010. Using bootstrapped concentration data for 118 representative foods, 93.5% of total intake was included in the exposure estimates in this study. Using the 2-day exposure data, we estimated long-term exposure by controlling for within-individual variation using the ISU method. RESULTS: The long-term dietary exposure estimates (mean [+ or -]standard deviation) for lead, cadmium, and mercury were 0.47 ± 0.14, 0.38 3 ± 0.20, and 0.22 ± 0.08 µg/kg bw/day, respectively. For lead and cadmium, the percentages of children whose exposure was greater than the reference value were 35 and 42%, respectively. Fruits were an important source of lead exposure, and cereal and fish and shellfish made the greatest contributions to the total cadmium and mercury exposure. CONCLUSIONS: Our findings also suggest that the long-term exposure to lead and cadmium was somewhat greater than the reference values, whereas mercury exposure was well below than the reference value in this population. Further studies may be necessary to evaluate the food items contributing to heavy metal exposure, and continuous monitoring is needed to ensure the safety of food intake and dietary patterns among vulnerable groups in Korea.

Abstract

A global model consisting of energy and particle balance equations has been formulated for inductively coupled oxygen rf discharge plasmas. The energy balance equation is inclusive of energy losses due to electron-neutral elastic collision, ionization, excitation, pair production, dissociation and charged particle wall loss. The scaling laws of plasma variables, together with the control parameters of the ion-flux-loss-dominated area, are estimated and compared using experimental data under the developed global model.
