Time Series Analysis between the Concentration of Air Pollutants and the Number of Respiratory Disease Outpatients in Seoul: Byeong Chul Choi, Jung Wan Koo, Sung Kyun Park, Hyun Woo Yim, Kang Sook Lee, Won Chul Lee, Chung Yill Park; Korean Journal of Occupational and Environmental Medicine 2000;12(1):70-80. Published online March 31, 2000; DOI: https://doi.org/10.35371/kjoem.2000.12.1.70

OBJECTIVES
This study was conducted to investigate whether air pollution levels in Seoul have short term effects on respiratory disease outpatients.
METHODS
We analyzed five air pollutants (CO, NOy, Oy, SOp, PMyp) and daily counts of outpatient for respiratory disease divided by age group ((15yrs, 15-64yrs, 65+yrs) during the period of July 1997-June 1998 using Generalized Additive Model(GAM).
RESULTS
After controlling for seasonal trends, day of the week, week of the month, temperature and humidity, CO (RR=1. 041 ~ l. 051, 0-day lag) and NOy (RR=1. 024~1. 050, 3-day lag) were significantly associated with daily counts for respiratory disease in all age groups. 0, and SO, were associated, with a 3-day lag in the age group under 15 years (O RR=1. 047, 95% CI=1. 045- 1. 049 i SOp RR=1. 018, 95% CI=1. 017- l. 020) and with a 0-day lag in the age group 15 to 64 years (0, RR=1. 035, 95% CI=1. 032-1. 037; SO, RR=1. 037, 95% CI=1. 035-1. 039), in the age group over 65 years (O RR=1. 042, 95% CI=1. 033-1. 051; SO RR=1.029, 95% CI=1.022-1.036). PM was weakly associated, with a 1-day lag in the age group under 15 years (RR=1.011, 95% CI=1.010-1.013) and with a 0-day lag in the age group 15 to 64 years (RR=1. 021, 95% CI=1. 019-1. 023), in the age group over 65 years (RR=1. 025, 95% CI=1. 018-1. 032). In the two pollutant model, the magnitudes of the relative risk for CO, NOy and Oq were maintained, but SOy was not associated with daily counts for respiratory disease in the age group under 15 years after controlling for NO,. PMyp was not associated in all age groups after controlling for CO, so the association with PMyp in the single pollutant model might be confounded by CO. In this study, the impact Of PMyp on the respiratory disease was not large as compared with other pollutants.
CONCLUSIONS
Air pollution in Seoul may increase the incidence of the respiratory disease, so more positive attention for the control of air pollution should be paid.

Adipose Tissue and Serum Levels of PCBs and DDE in Women with Gynecologic Benign Disease: Sung Kyun Park, Kang Sook Lee, Young Man Rho, Jung Wan Koo, Sun Young Min, Jin Goo Han, Won Kyoung Ko, Mi Ran Kim, Jae Keun Chung, Jong Seung Lee, Jin Hong Kim; Korean Journal of Occupational and Environmental Medicine 2000;12(1):81-92. Published online March 31, 2000; DOI: https://doi.org/10.35371/kjoem.2000.12.1.81

Abstract PDF: OBJECTIVES
This study was purposed to determine the levels of PCBs and DDE in adipose tissue and serum and to evaluate the relations with factors affecting these levels.
METHODS
We analyzed adipose tissues and sera from 52 gynecologic benign disease patients aged 27-78 years, except hormonal diseases such as breast cancer and endometriosis. We also surveyed age, education, occupation, body mass index (BMI), smoking, drinking, number of children, and duration of breastfeeding by questionnaires. Tissue and serum levels of PCBs and DDE were measured using gas chromatography.
RESULTS
The median and geometric mean levels of PCBs were 48. 29 ng/g, 56. 78 ng/g for adipose tissue and 4. 67 uc/L, 4. 85 m/L for serum, and those of DDE were 142.89 ng/g, 117.06 ng/g for adipose tissue and l. 75 m/L, 2.09 ua/L for serum, respectively. Adipose tissue and serum levels for DDE showed high correlation (r=0. 310, p=0. 0002), but those of PCBs didn' t (r=0.029, p=0.2582). In analyses of the differences of the means of log transformed adipose tissue and serum PCBs and DDE levels for groups of potential covariates, only adipose tissue DDE levels were significantly associated with number of children (p=0.015), age at first birth (p=0.014) and BMI (p=0.035). In multiple regression analysis, adipose tissue DDE levels were significantly increased with decreasing number of children and increasing age at first birth.
CONCLUSIONS
This study suggested that parity and adiposity were associated with levels of DDE in adipose tissue, and adipose tissue is a better biomarker than serum for evaluating the long-term exposure of organochlorines.

A Study on the Factors affecting Pesticide Poisoning of a Rural Population: Sung Kyun Park, Sang Min Nam, Gyu Seok Hwang, Hyunme Park, Soo Eun Chung, Eun Ju Kim, Hee Sun Kim, Byung Kwan Sun, Yun Jung Yang, Eun Hee Lee, Hyung Doo Cho; Korean Journal of Occupational and Environmental Medicine 1999;11(2):196-205. Published online June 30, 1999; DOI: https://doi.org/10.35371/kjoem.1999.11.2.196

Abstract PDF

The purpose of this study is to examine the pesticide use and the relationship between keeping the safety rules or use of protective equipments, and poisoning experience. For Puksan province, Choonchun county, we obtained questionnaire data concerning pesticide poisoning and relating factors from 143 people who have farmed and have sprayed pesticides. Important results are follows: 1. The rate of experiences of pesticide poisoning was 33%, and the major symptoms were dizziness(39. 13%), vomiting(20.87%), and visual opacity(11.30%). The most frequent use of pesticide was paraquat(23. 76%), and the next was organophosphates(18.35%). 2. Logistic regression and chi-square analyses showed that duration of spraying per day, following dose limits, and spraying back against wind are significantly associated with poisoning experiences(x2=5.620, p0.018, OR=0.326, CJ=0.109-0.968, OR=0.302, OR=0.097-0.939 respectively). But no associations between poisoning experiences and age, sex, use of protective equipments, and attendance of safety education. Based on these data, despite limitations in exposure assessment and recall biases, it may be necessary to devise a counterplan for development of effective safety education that prevents pesticide poisoning such as popular education in CATA pesticide project, as well as prohibition of use of hazardous pesticides that proved to be fatal.
