Title : Association between Blood Lead Level and Learning Achievement on the Students at Grinting 01 Elementary School, Bulakamba District, Brebes RegencyBackground: Plumbum (Pb) is a highly poisonous heavy metal, especially for the children. Pb enters the human body through the respiratory and gastrointestinal tract, and also skin. The aim of this study was to determine the correlation between blood lead level and the learning achievement on the students in Grinting 01 Elementary School, Bulakamba District, Brebes Regency. Methods: This study was an observational research using cross sectional design.  The subjects were 51 students. The data were collected using interview and observational field. The exposure of blood lead level was measured by detecting Pb content in blood according to the result of laboratory test by ASS method (Atomic absorbance spectrometer), and the learning achievement was measured using MST (Middle Semester Test) score of the students. Univariate analysis and bivariate analysis (Chi-Square) were used to analyze the data. Results: The result of bivariate test indicated that there was no correlation between blood lead level and learning achievement with p >0.05. For in the ehole samples, the blood lead level were more than Normal standard of CDC (≥5 µg/dL) with the highest Pb in blood is 48.39 µg/dL and the lowest is 11.06 µg/dL. Conclusion: In conclusion, Pb concentration - in blood on the children does not influence the learning achievement directly.

Cat Gene

Lead has been linked to the development of hypertension via oxidative stress. Catalase plays an important role in the disposal of hydrogen peroxide in erythrocyte and its activity was determined by CAT gene. The aims of this study were to investigate (1) the association between blood levels of antioxidant markers such as catalase, superoxide dismutase, glutathione, glutathione peroxidase, oxidative stress-marker (malondialdehyde), and blood lead level and (2) the influence of genetic polymorphism of CAT gene (rs769217) on change in blood pressure in general population of EGAT study project. This is a cross-sectional study of 332 normotensive, 432 prehypertensive, and 222 hypertensive male subjects. Hypertensive subjects had significantly higher blood lead level (5.28 μg/dL) compared to normotensive (4.41 μg/dL) and prehypertensive (4.55 μg/dL) subjects (P<0.05). These significant findings are also found in MDA levels. Moreover, individuals with TT genotype in hypertensive group had significantly higher blood lead and MDA levels (6.06 μg/dL and 9.67 μmol/L) than those with CC genotype (5.32 μg/dL and 8.31 μmol/L,P<0.05). Our findings suggested that decreased blood catalase activity in this polymorphism together with low level lead exposure induced lipid peroxidation may be responsible for hypertension.

The objective of this research was to identify the correlation between aerial lead level and blood lead level with hypertension of workers in car painting workshop Surabaya. This research was an observational with cross-sectional study and to know the correlation analyzed by using phi correlation. Sample of this research were 16 respondents taken from population compatible from defi ned criteria. Blood lead level and blood pressure examined by the health workers then analyzed in the laboratory and using questionnaires to determine the characteristic of respondents. The results of this research is 83.33% respondents were exposed have blood lead concentration exceeds the limit that is > 10 μg/dL and 66.67% respondents were exposed have hypertension. Blood lead concentration have a strong correlation with hypertension (r = 0.618). The workers need to do a routine blood lead concentration check up once every 6 months and use personal protective equipment at work, consume foods and beverages that contain high calcium often nevertheless decrease smoking habit to inhibit absorption of lead in blood.

Abstract Objectives Lead exposure in children contributes to 600,000 new cases of intellectual disabilities every year with maximum occurrence in developing countries. Currently limited information is available on the blood lead level (BLL) in children of India. The aim was to estimate BLL in the school going children of local population of Jodhpur. Methods Four hundred twenty-six primary school children of government and private schools participated in this cross sectional study. Information regarding possible lead exposure was collected. BLL was estimated on Lead Care II analyser (Magellan Diagnostics, USA). Results The mean and median BLL were 4.25 ± 1.75 μg/dL (<3.3–22.6 μg/dL) and 3.5 μg/dL (Inter Quartile Range 0.9). BLL was higher in children of illiterate mothers, those residing near traffic dense areas, urban region and studying in government schools of urban region. Conclusions BLL in children residing in Jodhpur is much higher in comparison to western counterparts. Screening and awareness programs regarding potential sources of lead exposure can help in improving BLL.

Poisoning In Children

Background Lead poisoning is a source of health problems inhumans. A chronic complication oflead poisoning in children ispermanent intellectual impairment.Objective To assess for a correlation of blood lead levels andintelligence quotient (IQ) in children.Methods A cross-sectional study was performed in children aged6 to 8 years in th e Talawaan (a rural area) and Wenang (an urbanarea) Distticts, North Sulawesi, from April to July 2012. Blood leadlevels were measured using the graphite furnace atomic absorptionspectrometry technique; and intelligence was meas ured with theWechsler Intelligence Scale for Children-Indonesian version.Results There were 50 subjects from the Talawaan District and 54subjects from the Wenang Disttict in this study. The mean bloodlead level in the Talawaan District subjects was significantly higherthan that of the Wenang Disttict subjects [25.8 (SD 16.98) μgidLvs 11.4 (SD 13.81) μgidL, respectively; (P<0.001)]. There was aweak negative correlation between blood lead level and IQ in theTalawaan Disttict children (P= 0.038; r= -0.3). As such, there wasa 0.05 IQ point decrement associated with each increase of 1 μ gidLin blood lead level in Talawaan District children. However, therewas no correlation between blood lead level and IQ in the WenangDisttict children (P=0.42; r =0.03).Conclusion There is a weak negative correlation between bloodlead level and IQ in children living in a rural area, howevei; thiscorrelation is not found in children living in an urban area.

AbstractBackground: To evaluate whether salivary lead can be used as a surrogate for blood lead, and if so, over what concentration range.Methodology: Three saliva devices were evaluated and one chosen to undertake this project. Paired saliva and blood samples were collected from 89 UK lead workers. Lead concentrations were determined using ICP-MS. In addition, haemoglobin and ZPP levels were determined in the blood samples and albumin was determined in the saliva samples to investigate standardisation using protein adjustments.Results: The chosen saliva device gave low but consistent recoveries for lead in saliva and the blank levels were low. The mean +/- SD blood lead level was 19.9 +/- 14 μg/dl; the mean +/- SD saliva lead level was 19.1 +/- 32.5 μg/l for 89 workers. Log10-transformed data showed correlation of r=0.69. The protein adjustments did not improve the blood-saliva correlation.Conclusions: This study has demonstrated that salivary lead measurement is feasible and correlated with blood lead levels, at least at occupational exposure levels, and may have value as a screening technique. Correlation may improve at environmental levels where exposures are generally more consistent and chronic, although this needs to be demonstrated in a genuine environmental population.
