Background

We evaluated the level and factors of heavy metal exposure to children residing in the Togttsetsii, Khanbogd, and Bayandalai soums of South Gobi province, Mongolia.

Methods

A total of 118 children aged 9–12 years were surveyed, and the level of heavy metal exposure in their bodies was investigated. Exposure was investigated by measuring concentrations of heavy metals such as cadmium, lead, and mercury in the blood; mercury concentration in the hair; and total arsenic in the urine.

Results

Blood cadmium concentration had geometric averages of 0.16 µg/L in the children from Bayandalai, 0.15 µg/L Tsogttsetsii, and 0.16 µg/L Khanbogd. Blood lead concentration showed a relatively higher geometric average of 7.42 µg/dL in the children from Bayandalai compared to 4.78 µg/dL and 5.15 µg/dL in those from Tsogttsetsii and Khanbogd, respectively. While blood mercury concentration was the highest in the children from Bayandalai, with a value of 0.38 µg/L, those from Tsogttsetsii and Khanbogd had similar concentrations of 0.29 µg/L and 0.29 µg/L, respectively. Hair mercury concentration was the highest in the children from Bayandalai, with a value of 78 µg/g, a particularly significant difference, with a concentration of 0.50 µg/g in those from Khanbogd. Urine arsenic concentration was the highest in the children from Khanbogd, with a value of 36.93 µg/L; it was 26.11 µg/L in those from Bayandalai and 23.89 µg/L in those from Tsogttsetsii.

Conclusions

The high blood lead concentration of children in Bayandalai was judged to be due to other factors in addition to mine exposure; the reason why blood and hair mercury concentration was higher in children from Bayandalai may have been due to exposure to many small-scale gold mines in the area. In the case of Khanbogd, it was estimated that the high arsenic level in urine was caused by the effect of mines.

Background

Rhinitis was the most frequently diagnosed disorder among users of humidifier disinfectants (HDs). The aim of our study was to investigate on the relationship between allergic rhinitis (AR) and HD uses.

Methods

Our study used the data from the eighth Panel Study on Korean Children; a total of 1,540 participants were enrolled. The χ2 test and multiple logistic regression analyses were conducted to debunk the association between AR and HD uses.

Results

In our analysis, odds ratios (ORs) of doctor-diagnosed AR increased significantly when simply the response of whether HDs were used in the past was considered. When the brands of HD were considered, ORs of doctor-diagnosed AR were found to be increased significantly for those who have used polyhexamethylene guanidine phosphate/oligo(2-[2-ethoxy]-ethoxyethyl)guanidinium-containing HDs (model 3: 1.41, 95% confidence interval [CI]: 1.02–1.95). However, once duration of usage was additionally considered, ORs of doctor-diagnosed AR increased significantly only for those who have used chloromethylisothiazolinone/methylisothiazolinone-containing HDs for more than or equal to 3 months (model 3: 2.08, 95% CI: 1.17–3.69). Further, past use of HD was associated with significantly increased ORs of AR diagnosed before 2013 (model 3: 1.35, 95% CI: 1.02–1.79).

Conclusions

Results of our study suggest that past uses of HDs may be associated with an increased risk of AR.

Korean Journal of Occupational and Environmental Medicine 2009;21(3):218-224.   Published online September 30, 2009

AbstractAbstract PDF
OBJECTIVE: To evaluate the changes in respiratory function associated with daily changes in particulate pollution.
METHODS
A total of 105 healthy schoolchildren of fourth and fifth grade elementary school age performed peak expiratory flow rates (PEFR) during 2 periods (May 14~June 15, Oct 22~Nov 23). We monitored concomitant ambient particulate matter (PM) levels during the periods.
RESULTS
An elevation PM(10) level of 1 microgram/m) led to decreases in PEFR of 0.20 L/min. A 1 microgram/m3 elevation of PM(2.5) led to a decrease of 0.36 L/min in PEFR. In addition, 1 day lag was associated with PM(10) levels and PEFR changes, and PM(2.5) showed the same result. The metal levels determined at PM(10) and PM(2.5) were found to be associated with decreased respiratory function.
CONCLUSIONS
An association between respiratory function and particulate pollution was observed when particulate pollutant levels were lower than the yearly average National Ambient Air Quality Standard in the Korea(50 microgram/m3).

Hematological Changes and Immunological Function in Children Living Near the Petrochemical Estate in Ulsan
Choong Ryeol Lee, Cheol In Yoo, Ji Ho Lee, Hun Lee, Yang Ho Kim
Korean Journal of Occupational and Environmental Medicine 2001;13(2):127-140.   Published online June 30, 2001
DOI: https://doi.org/10.35371/kjoem.2001.13.2.127
AbstractAbstract PDF
OBJECTIVES
To evaluate the hematological changes and the immunological function of children living near the petrochemical estate in Ulsan.
METHODS
The study subjects comprised of 238 children who consisted of 143 children living near the petrochemical estate and 95 children living in a suburban area. We conducted the hematological examination 3 times, in April, July and October. Also we evaluated the immunological function of some children in July. To confirm differences between schools repeated measures ANOVA of generalized linear model was done controlling age and sex as covariates.
RESULTS
The blood cell counts of children showed differences between schools in accordance with the survey month. The total WBC, neutrophil, and lymphocyte counts of children living in a suburban area decreased in July and increased in October again, but those of some children living near the petrochemical estate did not changed distinctly. The RBC counts of children living in a suburban area decreased in July and increased in October again, but those of some children living near the petrochemical estate decreased as time passed. The changes of the amount of hemoglobin of all study subjects were similar with those of RBC. The platelet counts of all study subjects decreased in July and increased in October again. In the generalized linear model, school was a significant independent variable for the total WBC, RBC, and platelet counts, and sex was a significant independent variable for the RBC counts. Age was a significant independent variable for the lymphocyte and platelet counts. P values of all blood cell were statistically significant in interaction variable between the survey month and school, and those of the total WBC, neutrophil, and lymphocyte counts were statistically significant in interaction variable between the survey month and age. The immunological function showed no significant difference between study groups.
CONCLUSIONS
The total WBC and RBC counts which would be easily affected by volatile organic compounds(VOCs) in the atmosphere showed differences between schools in accordance with the survey month. This suggests that the amounts of exposure to VOCs are different among each school children in different months. To ascertain the hematological changes by VOCs, an additional study evaluating the concentrations of atmosphere of VOCs and biological monitoring of some VOCs is needed.

Yong Hwan Lee, Duk Hee Lee, Jin Ha Kim, In Geun Park, Tae Young Han, She Han Jang
Korean Journal of Occupational and Environmental Medicine 1995;7(1):82-87.   Published online February 28, 1995
DOI: https://doi.org/10.35371/kjoem.1995.7.1.82
AbstractAbstract PDF
The authors conducted this study to evaluate some differences in blood lead levels between inner-city and suburban children and obtain the basic data of the reference value of the blood lead concentrations in children. The subjects were composed of 102 children residing in inner-city and 86 children in suburban. Their age range were 6 to 8 years old and the obtained results were as follow; 1. The arithmetic means of the blood lead level in male and fenlale, male, and female children were 7.24, 7,40, 7.08 microgram/100ml, and geometric means were 6.92, 7.08, 6.76 microgram/100ml, respectively. 2. The children residing in inner-city had the higher blood lead levels both male and female than suburban children with statistical signficance (p < 0.05) 3. Seventeen percent of the total subjects had lead cencentrations ( 5 microgram/100ml, and 5.88% of inner-city children and 30.23 % of suburban children had this lead values. But in > or = 10 microgram/100ml group, the inner-city children (20.39 %) were more distributed than suburban chilren(2.33 %) , and 12.33 % of total subjects had this lead values.
