김화성,이성수,김용배,황보영,리갑수,안규동,장봉기,이병국 大韓産業醫學會 2001 대한직업환경의학회지 Vol.13 No.1

목 적 : 혈중 연량 및 골중 연량과 조혈기능의 생화학적 지표사이의 관련성에 f-aminolevinicacid dehydratase 효소의 유전형질의 다형질성이 어떠한 영향을 주는지를 알아보고자 연작업자 450명을 연폭로군으로 연폭로가 없는 85명을 대조군으로 선정하였다. 방 법 : 조혈기능의 생화학적 지표로는 혈중ZPP, 요중 ALA, 혈색소 및 혈구용적치를 택하였고, 이들 상호관계에 영향을 줄 수 있는 교란변수로서 성, 연령, BMI, 흡연습관, 음주습관 및 연작업자들의 경우 연폭로 기간을 조사하였다. 결 과 : 동형유전형질인 ALADI을 가진 연작업자들은 407명으로 전체의 90.4 %이었으며, 대조군에서도 77명으로 전체의 90.6 %로서 양군간에 차이가 없었다.동형 유전형질을 가진 연작업자들보다 이형 유전형질을 가진 연작업자들의 골중 연량과 혈중 ZPP의 평균값이 적었으나 통계적으로 유의하지 않았고 나머지 연구변수들의 평균도 유전형질의 구분에 따른차이는 없었다. 성, 직력, BMI, 흡연여부, 음주여부 등의 흔란변수를 통제한 후 혈중 연량 및 골중 연량과 ALAD유전형질이 혈색소에 미치는 영향을 구한 바 혈중 연량과 골중 연량만이 혈색소에 유의한 영향을 주었을뿐 ALAD 유전형질은 유의한 영향이 없었다. 반면에 혈구용적치의 경우에는 혈중 연량과 골중 연량 그리고 유전형질 모두가 유의한 영향을 주지 못했다.요중 ALA를 종속변수로 하고 관련 혼란변수를 통제한 후 혈중 연량과 ALAD 유전형질 그리고 양자의 교호작용을 독립변수로 한 회귀분석들에서 혈중 연량 및 골중 연량과 ALAD 유전형질 모두가 주효과(main effect) 및 교호작용(effect modifies-tion)이 유의하석 이형 ALAD 유전형질을 가진 연작업자들의 ALAU가 동형의 유전형질을 가진 연작업자들보다 상대적으로 낮은 값을 나타냈다.혈중 ZPP를 종속변수로 하고 관련 혼란변수를 통제한 후 혈중 연량과 ALAD 유전형질 그리고 양자의 교호작용을 독립변수로 한 회귀분석들에서 혈중연량 및 골중 연량과 ALAD 유전형질 모두가 음의주효과(maln effect)가 나타나서 이형 유전형질의 연작업자들의 혈중 ZPP가 동형 유전형질의 연작업자보다 상대적으로 적은 값을 나타냈으나 교호작용(effect modification)은 없었다. 결 론 : 상기 결과로 미루어 ALAD 유전형질은 혈색소에는 유의한 영향을 주지 못했으나 ALAU 및 혈중 ZPP에는 유의한 영향을 주어 동형의 유전형질인 연작업자보다 이형의 유전형질 연작업자들이 상대적으로 낮은 ALAU와 혈중 ZPP값을 보여주어이형유전형질이 연에 보호효과가 있다는 가설을 돼받침하였다 Objectives : To evaluate the effect of ALAD polymorphism on the relationship of blood and bone lead with hematologic biomarkers in lead exposed workers, 450 lead exposed workers and 85 non-lead exposed workers were selected. Methods : Blood lead and tibia bone lead were selected as parameters of lead exposure and blood ZPP, urinary ALA (ALAU) , hemoglobin (Hb) and hematocrit (Hct) were chosen as parameters of hematologic effect of lead exposure. Genotype of each subject was assayed and expressed as ALADI and ALAD2. Demographic information such as sex, age and personal habit of smoking and drinking were collected. Job duration of lead exposed workers was also obtained. Results : The overall prevalence of the variant allele, ALAD2 in lead exposed workers was 9.6 %(43 out of 450 lead workers) which was not differed from control workers (9.4 % : 8 out of 85) . The means of tibial lead and blond ZPP in lead workers with ALAD2 were lower than those of lead workers with ALAD1, but the differences were not statistically significant. After adjusting for possible confounders (sex, job duration, BMI, drinking and smoking status) only blood lead and bone lead contributed negatively to the level of hemoglobin with statistical significance without any contribution of ALAD genotype. On the other hand, no significant effect of blood lead, bone lead and ALAD genotype were observed on the level of hematocrit after controlling possible confounder. ALAD genotype in the multiple regression analysis of blood lead fed bone lead with log transformed urinary ALA (LogALAU) after adjusting for possible confounders showed significant main and interaction effect on LogALAU simultaneously, which resulted lower LogALAU in lead exposed workers of ALAD2 than ALAD1. It was also observed only main effect of ALAD gene type on blood ZPP after adjusting possible confounder resulting lower ZPP in lead workers of ALAD2 than ALAD1. Conclusions : With above results, it was found that ALAD polymorphism did not affect on the level of hemoglobin and hematocrit, but ALAD polymorphism made significant effect on the association of blood and bone lead with urinary ALA and blood ZPP. The lower urinary ALA and blood ZPP in ALAD2 lead workers suggested that ALAD2 genotype may be supportive for the protective effect of lead.

납 폭로 근로자에서 δ-aminolevulinic acid dehydratase 유전형질이 zinc protoporphyrin 및 δ-aminolevulinic acid에 미치는 영향

The inhibition of δ-aminolevulinic acid dehydratase (ALAD) in the heme synthetic pathway results in increased protophoryphyrin (ZPP) and δ-aminolevulinic acid (ALA) and is responsible for some of toxicological effects of lead. This enzyme is coded by the ALAD gene containing 2 co-dominant alleles. The polymorphisms of ALAD gene may be related to differential effects of lead on ZPP and ALA, ALAD genotype was measured in 975 Korean male lead workers, of whom 897 were homozygous for ALAD1 (ALAD 1-1 genotype) and 96 were heterozygous for ALAD2 (ALAD 1-2 genotype). Blood lead in subjects with ALAD1 was significantly higher than those with ALAD2 (p = 0.01). No difference between ALAD genotypes was found for age, exposure duration, ZPP, ALA, hemoglobin, hematocrit, body mass index, tobacco and alcohol use. After adjustment for possible confounders, ALA and ZPP became significantly elevated in ALAD1 subjects (p = 0.004 and 0.055, respectively). This result suggests that ALAD1 subjects may be more susceptible to the hematotoxicologic effects of lead than ALAD2 subjects.

The acid value (AV) as well as the ester value of essential oil is an important index to evaluate quality of essential oil. The official standard analytical method of KS H ISO 1242 dealing with “Essential oils - Determination of acid value” was assessed experimentally using two lavandin essential oils obtained in France as an example. One French lavandin oil sample showed the results of AV= 0.9 by both indicator method and potentiometry. Another sample showed AV = 1.9 by indicator method and AV = 1.6 by potentiometry. Latter lavandin oil sample exhibited significantly higher acid value than maximum value of 1 described in the standard. This result suggests that latter lavandin oil was contaminated, because this oil was contained in an orange juice bottle. Results of this study proved that KS H ISO 1242 could be used as a suitable scientific standard for the determination of acid value of essential oils.

To assess lead exposure in Korean lead workers, 2047 male lead workers in 17 lead using industries were studied. Study population were divided into 4 occupation categories such as storage battery industry(type 1), secondary smelting and litharge making industries(type 2), PVC stabilizer making industries(type 3) and primary smelting and related industries (type 4). Blood lead and zinc protoporphyrin in whole blood (ZPP) were selected as an index of lead exposure. Hemoglobin and hematocrit were also checked. Fifteen questionnaires of lead related symptoms were provided to all lead workers and filled up by themselves and confirmed by medical doctors. Personal variables such as age, work duration, smoking and drinking habits were also collected. the results were as follows. 1) The mean blood lead, ZPP and hemoglobin of all lead workers were 29.7+12.6㎍/100㎖, 56.5+38.6㎍/100㎖ and 14.6+1.3 gm/100㎖ respectively. 2) While the mean blood lead of lead workers in type 1, 2, 3 and 4 were 28.6+11.6㎍/100㎖, 46.2+15.3 ㎍/100㎖, 46.8+12.1 ㎍/100㎖ and 26.2+10.2 ㎍/100㎖, the mean value of blood ZPP of those workers were 53.6+32.6 ㎍/100㎖, 108.1+87.1 ㎍/100㎖, 98.9 +54.9 ㎍/100㎖ and 45.8+19.5 ㎍/100㎖ respectively. 3) The percents of lead workers whose blood lead were 40-59.9 ㎍/100㎖ and over 60.0 ㎍/100㎖ were 17.6% and 2.1% respectively. Those whose blood lead were 40-59.9 ㎍/100㎖ and over 60.0 ㎍/100㎖ were 15.18% and 0.96% for type 1, 43.59% and 21.79% for type 2, 58.89% and 12.22% for type 3 and 11.82% and 0% for type 4 respectively. 4) The percents of lead workers whose blood ZPP were 100-149 ㎍/100㎖ and over 150 ㎍/100㎖ were 5.17% and 3.17% respectively. Those whose blood ZPP were 100-149 ㎍/100㎖ and over 150 ㎍/100㎖ were 4.66% and 2.04% for type 1, 10.26% and 25.64% for type 2, 23.33 and 13.33% for type 3 and 1.28% and 0.32% for type 4 respectively. 5) The prevalence rate of smoking and drinking of male lead workers in all lead industries were 70.8% and 71.0% respectively. While the mean blood lead of smoker, non-smoker, drinker and non-drinker were 30.24+12.58 ㎍/100㎖, 28.35+12.7 ㎍/100㎖, 30.24 ㎍/100㎖ and 28.74 ㎍/100㎖ respectively, the mean blood ZPP of those were 55.7+37.1 ㎍/100㎖, 58.4+41.9 ㎍/100㎖, 55.7+36.5 ㎍/100㎖ and 58.4+43.3 ㎍/100㎖ respectively. 6) While the correlation of hematocrit corrected blood lead with other lead exposure variables were higher than non-corrected blood lead, the correlation of log-transformed ZPP with other lead exposure variables were higher than non-corrected blood ZPP. 7) The most frequent symptom among 15 lead related symptom questionnaires was 'general fatigue' and the next one was 'feeling irritated with disturbance' and least one was 'acute abdominal pain around the umbilicus' in all lead workers. The overall prevalence of lead workers in storage battery industry and primary lead smelting industry were higher than secondary lead smelting and PVC stabilizer making industries. 8) The prevalence of lead related symptoms was a little higher in 13 symptoms in smokers than non-smokers and in 14 symptoms in drinker than non-drinkers, but they were not statistically significant. 9) Stepwise multiple regression analysis, using overall symptom prevalence as a dependent variable blood lead, blood ZPP, hemoglobin, age, work duration, drinking and smoking habits as independent variables, indicated that smoking habit, drinking habit and age were significantly contributed to the dependent variable. 10) The slopes of simple linear regression of blood lead (independent variable) with blood ZPP and log-transformed ZPP as dependent variable were different among 4 types of lead industries. The slope of lead industries with low mean blood lead were less steeper than those with high mean blood lead.

In order to obtain an useful information for health management and biological monitoring of lead exposed workers, Authors tried to investigate air lead level and the lead exposed level of workers in lead industry according to occupational category. The subjects in our study were 2074 workers in 7 lead-using industries, and study subjects were divided into 4 occupational categories such as storage battery industry (type 1), primary smelting industry (type 2), secondary smelting industry (type 3) and litharge making industry (type 4). Blood zincprotoporphyrin concentration (ZPP), blood lead concentration (PbB) and urinary δ -aminolevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct) were selected as the indices of lead exposure. Personal variables such as age, work duration were also collected. The results were as follows. 1. The geometric mean air lead in 9 lead-using industry was 0.1133±4.3120 ㎎/㎥, and that in type 1, 2, 3 and 4 was 0.1038±3.4952 ㎎/㎥, 0.0429±3.4329 ㎎/㎥, 0.1877±2.5123 ㎎/㎥ and 0.9961±5.2910 ㎎/㎥, respectively. 2. The mean ZPP in 9 lead-using industry was 53.1±28.0 ㎍/㎗, and that in type 1, 2, 3 and 4 was 52.0±24.8 ㎍/㎗, 48.0±16.4 ㎍/㎗, 109.8±85.6 ㎍/㎗ and 74.3±37.8 ㎍/㎗, respectively. There was significant difference in ZPP according to occupational category (P<0.01). The percents of lead workers whose ZPP were above 100 ㎍/㎗ in type 1, 2, 3 and 4 were 4.0%, 1.7%, 34.3% and 21.6%, respectively. 3. The mean PbB in lead-using industry was 26.0±11.2 ㎍/㎗, and that in type 1, 2, 3 and 4 was 25.3±11.1 ㎍/㎗, 26.7±8.8 ㎍/㎗, 50.3±15.2 ㎍/㎗ and 36.4±11.0 ㎍/㎗, respectively. There was significant difference in PbB according to occupational category (P<0.01). The percents of lead workers whose PbB were above 40 ㎍/㎗ in type 1, 2, 3 and 4 were 10.4%, 7.7% 71.9% and 43.2%, respectively. 4. While the correlation of Hb corrected PbB with ZPP was higher than non corrected PbB, the correlation of log-transformed ZPP with PbB was higher than non corrected ZPP. 5. Simple linear regressions of PbB and corrected PbB as independent variable with ZPP, log-transformed ZPP and ALAU as dependent variable were statistically significant (P0.01). Coefficient of determination of corrected PbB with other variables was higher than non corrected PbB. As the result of this study, it was suggested that reconsideration of environmental and biological monitoring program was highly recommended for secondary smelting and litharge making industry.
