As such, there are many other disorders that may cause an elevated LDH. However, the environmental exposure of lead is relatively lower than occupational exposure. Barbosa F, Tanus-Santos JE, Gerlach RF, Parsons PJ. Your doctor will run tests to determine whether you have lead poisoning and how severe it is. Environ Health Perspect. Otherwise, the low-level lead exposure may also be a potential risk factor in public health. Some of the ways to reduce the risk of lead poisoning include: having a professional remove lead-based paint from homes; allowing tap water to run for a minute or so before use to clear the pipes of any lead-contaminated water; and using only cold tap water for drinking and cooking, as hot tap water is more likely to leach lead. We first collated BPb and indicators of hematopoietic function data via health examination records that included 533 male and 218 female lead-exposed workers between 2012 and 2014. To integrate the risk estimates across different models, the model-averaging BMD was applied by calculating the weight w The hazard prevention probabilities were estimated 32.0% and 22.9% under unadjusted and adjusted scenarios, respectively. Shih RA, Hu H, Weisskopf MG, Schwartz BS. Fairfax R, Kilens G. Lead control in a bronze foundry. Many biomonitoring methods are capable of measuring the bioaccumulation of lead in the human body [1]. Male workers in the lead battery manufacturing processes of grinding, cutting, and filling had relatively higher BPb concentrations than those in other working areas. To determine the BPb levels in health management, we examined the simulated BPbs that were set at 25 and 35 μg/dL for male workers. 0, b Jon Meiman, MD; Robert Thiboldeaux, PhD; Henry Anderson, MD. Some of the effects are permanent. Symptoms include abdominal pain, confusion, headache, anemia, irritability, and in severe cases seizures, coma, and death. [30] reported that BPb levels of 10–20 μg/dL could precipitate anemia. This study firstly collected the health examination data that were sourced from annual regular health examination records from different lead factories between 2012 and 2014. Each simulation was carried out with 10,000 iterations to assure the stability of its probability distribution. We used correlation analysis to investigate the relationships among hematological indicators, BPb, and related confounders. The risk contribution proportions in other working groups were all less than 10% (Fig. Toxicol Appl Pharmacol. The case highlights the importance of occupational anamnesis for the diagnosis of lead poisoning, an uncommon condition which may mimic a variety of internal and surgical diseases. Among female workers, model averaging BMD10 estimates were 8.6 (BMDL10: 5.5), 9.8 (6.3), 12.1 (9.4), and 10.7 μg/dL (7.9) for Hct, RBC, MCV, and MCH, respectively (Tables S6 – S9).

Therefore, we assumed that the cumulative BPb that sourced from workplace or other area can be associated with the change of the hematological indicators. We found out that the abnormal proportion of indicator can exceed 20% for male workers in the exposure groups of grinding, powder, formatting, assembling, and charging, whereas the abnormal proportion may exceed 20% for female workers in every working group. The possible threshold of lead-associated anemia was also proposed by previous studies, which was approximately 20 μg/dL for lead workers [11, 16]. It seems that appropriate engineering control measures and hygiene strategies still play an important role in limiting lead exposure for female lead workers [27]. Lead levels in bone, blood, urine, and exfoliated teeth are the major biomarkers of internal dose. Interdiscip Toxicol. Data are however available from the authors upon reasonable request and with permission of the lead factories in Taiwan. Memory and concentration problems. We also found out that some lead workers may still work in an unsafe condition with risk estimates of HI > 1, especially for female workers. Properties of model-averaged BMDLs: a study of model averaging in dichotomous response risk estimation. Incorporating uncertainty and variability in the assessment of occupational hazards. In recent years, these low-dose toxic effects of lead have received considerable attention, thereby questioning the capability of the current standard for critical dose of lead to protect the health of lead-exposed population. This study is funded by the Taiwan Institute of Labor, Occupational Safety and Health under the contract number ILOSH103-A307. Ann Occup Hyg. 2010;213:99–106. The most compelling epidemiology evidence shows that the increased cardiovascular morbidity and mortality in populations with BPb in the low to medium range of 10 to 20 μg/dL [25, 26]. Lead poisoning occurs when lead is ingested. The BMDs for lead exposed-induced health effects provided the novel limits on BPb for health management. 2014;58:1079–93.

PubMed Central  It may cause potentially permanent learning and behavior disorders in children, as it affects nervous system development. Lead poisoning can cause anemia. We used correlation analysis is the preliminary exam in effect analysis that allows us to understand the strength between the effect factors and anemia-associated indicators. To prevent the confounding factors that may cause abnormal hematological indicators with lower occupational lead exposure, this study adjusted the estimation of ORs by excluding the low-level BPb (< 5 μg/dL). Unacceptable hazard occurrence probability was approximately 11.1% for total lead workers. … 2015;12:S7–17. Review of the peripheral smear is crucial. All rights reserved. Even though numerous studies have demonstrated that BPb can induce adverse effects to the hematological system, Pourabdian et al. $$, $$ \mathrm{TR}=\sum_{\mathrm{i}=1}^{\mathrm{n}}\left({HI}_{\mathrm{i}}\times {p}_{\mathrm{i}}\right), $$, $$ {\mathrm{R}}_{\mathrm{job}}=\frac{{\mathrm{HI}}_{\mathrm{i}}\times {p}_{\mathrm{i}}}{\mathrm{TR}}. The goal of this study was to examine the association between lead exposure and anemia risk among factory workers in Taiwan. We chose the dose-response dataset with p-value <0.05 to perform subsequent data analysis. Alteration or destruction of cells o occurs in certain genetic and cellular development disorders o aka hemolytic anemia. Thus, hazard occurrence probability can be calculated by using the proportion of simulated HI which value is greater than 1. Google Scholar. By using this website, you agree to our The impact of biochemical and enzyme changes (and their possible sequelae) that may exist at lower blood lead levels remains … The Cochran-Armitage test for trend analysis was used to assess the presence of a dose-response relationship. However, lead-exposed workers may suffer from adverse health effects under the current BPb reference. McNally K, Warren N, Fransman W, Entink RK, Schinkel J, van Tongeren M, Cherrie JW, Kromhout H, Schneider T, Tielemans E. Advanced REACH tool: a Bayesian model for occupational exposure assessment. It would be better to establish a new occupational strategy and enhance the education and training to reduce the BPb concentrations and subsequent hematotoxicity. Three cases of lead poisoning with a hypochromic anaemia, despite adequate iron stores, are presented and discussed. PubMed Central  Lead poisoning can also cause anemia. Our results indicated that HI for total lead-exposed workers was 0.78 (95% confidence interval: 0.50–1.26) with risk occurrence probability of 11.1%. Ntzoufras I. Bayesian Modeling Using WinBUGS. where p Unquestionably it occurs in lead poisoning more frequently than in any other of the secondary anemias and in leukemia, as well as in the cells invaded by the parasite of tertian malaria, and in some of the infectious diseases of childhood, including pneumonia, had resulted in much uncertainty as to its precise significance in lead poisoning. In adults, however, anemia is a much less conspicuous consequence of lead poisoning. Continue Reading. Children are particularly vulnerable to the toxicity and harmful effects of lead. Lead poisoning is considered the most well characterized occupational disease. 2005;5:344–57. The authors assume full responsibility for the content of the paper. Nerve disorders. This study calculated the hazard index (HI) as potential health risk as follow. (DOCX 27 kb). Our results also revealed that 95% CIs of Bayesian analysis-based ORs all cover the value of 1, indicating that the risk control efficiency may be slightly insignificant. A useful diagnostic algorithm has been recently published in the Mayo Clinic Proceedings.1 . Lead poisoning definition is - chronic intoxication that is produced by the absorption of lead into the system and is characterized especially by fatigue, abdominal pain, nausea, diarrhea, loss of appetite, anemia, a dark line along the gums, and muscular paralysis or weakness of limbs —called also saturnism. However, this correlation was not observed in female workers. 1) where Y Our results found out that there were slight differences when considering these two BPb levels for male workers. PubMed  Therefore, we used hematological indicators to represent BPb-induced anemia. Our study protocol was approved by the Institutional Review Boards I of the Tri-Service General Hospital, National Defense Medical Center (TSGHIRB: A-1-103-05-004). High blood pressure.

Wu HM. Our approach had also been widely used in exposure analysis and risk decision-making in environmental and occupational health research [28, 29]. Our results show that BMD10 and BMDL10 estimates ranged from 23 to 87 and 15–48 μg/dL for male workers after adjusting for of age and working years. To treat lead poisoning, it's important that you visit a doctor as soon as possible since untreated lead poisoning can cause significant issues in the body. PubMed Central  Lead-exposed workers need to be continuously controlled and reduce their BPb even if levels are under the current limits of 40/30 μg/dL for male/female workers. Appl Occup Environ Hyg. Scientific World J. Talk … Nonetheless, BPb levels in female workers needs to be carefully revised in order to prevent the lead-related anemia risk. 2013;54:325–8. Figure 5 shows the results of decision analysis. J Occup Environ Hyg. It can be seen that estimated ORs were relatively higher when we adopted 15 μg/dL as BPb limit. 1999;35:595–603. The hazard prevention probabilities for female workers were 85.5–95.0% when BPb limit of 15 μg/dL was adopted. We observed some abnormal hematological indicators in female workers who had lower BPb concentrations, an effect which may have been due to menstruation or pregnancy. $$, \( \mu \left(\mathrm{BMD}\right)={\sum}_{k=1}^K{\mathrm{BMD}}_k\cdot {w}_k \), \( \mu \left(\mathrm{BMDL}\right)={\sum}_{k=1}^K{\mathrm{BMDL}}_k\cdot {w}_k \), http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, https://doi.org/10.1186/s12889-017-4315-7. The best-fitted model and associated BMD and BMDL for each dose-response relation were selected based on the Akaike’s information criterion (AIC) and p-value of Chi-squared (χ2). PubMed  To investigate the association of specific hematological indicators with BPbs, we performed a Pearson-based correlation analysis (Fig. Kidney damage. This study focuses on the dose-response relationship between BPb concentration and the hematological indicators from regular health examination. PubMed  The authors declare that they have no competing interests. This result might due to the fact that female workers had relatively lower BPb levels compared to males.

Lead poisoning: historical aspects of a paradigmatic "occupational and environmental disease". ORs and adjusted ORs in male workers were 1.00 (95% CI: 0.84–1.18) and 1.10 (0.85–1.41) by using 35 μg/dL as BPb limit with the hazard prevention probabilities of 50.6% and 76.2% under unadjusted and adjusted scenarios, respectively. 2014;122:1160–5. The anemia of lead intoxication is hypochromic and normo -or microcytic with associated reticulocytosis. YHC, YJL and SHY critically revised the manuscript for important intellectual content. The data that support the findings of this study are available from the lead factories in Taiwan but restrictions apply to the availability of these data, which were used under license for the current study, and so are not publicly available. Because these symptoms may occur slowly or may be caused by other things, lead poisoning can be easily overlooked. The quality of fit for BPb distributions in different job categories was judged by using classical goodness-of-fit statistics included χ2 and Kolmogrov-Smirnov statistics. Moreover, when we adopted 25 μg/dL as BPb limits, the results of ORs and adjusted ORs were 1.04 (0.88–1.23) and 1.09 (0.87–1.37) with the hazard prevention probabilities of 67.0% and 76.9% under unadjusted and adjusted scenarios, respectively. Grover P, Rekhadevi PV, Danadevi K, Vuyyuri SB, Mahboob M, Rahman MF. Kosnett [8] recommended that women who are or may become pregnant and have a BPb > 5 μg/dL should reduce their exposure to lead. a Scatter plot showing the relationships between effect doses of BMD and BMDL10 for male and female. Based on the probability distribution (Fig. BMC Public Health The highest BPb concentration was observed in lead stearate factories. Koh DH, Nam JM, Graubard BI, Chen YC, Locke SJ, Friesen MC. The permissible exposure limit (PEL) is 50 μg/m3 in Taiwan. The main purpose of this study was to assess the risk of anemia for workers in lead factories and to provide a suggested BPb limit to improve health management for lead workers. Thus, the anemia risk can also be reduced when a more stringent BPb level is adopted. Among female workers, hematological indicators had significant dose-response trend for Hct (χ2 = 2.110; p < 0.05), RBC (χ2 = 1.849; p < 0.05), MCV (χ2 = 1.887; p < 0.05), and MCH (χ2 = 2.472; p < 0.01) (see Additional file 2: Tables S6 – S9). 2007;115:483–92.

Within a lead battery factory, the manufacturing areas were classified as casting, grinding, powder, filling, formatting, cutting, assembling, charging, packaging, or other off-site positions. 1, b Estimation of the posterior distribution of ORs can be simply obtained by simulating the distribution of f(π 2016;58:e371–4. Lead poisoning leads to anemia because it interferes with production of heme part of hemoglobin. No sponsor or advertiser has participated in, approved or paid for the content provided by Decision Support in Medicine LLC. Moreover, we were unable to collect information about the menstruation or pregnancy from our collated data for female workers. PubMed  According to our correlation analysis, we found that BPb had significantly negative correlations with hematological indicators in male workers. Lin-Tan DT, Wang ML, Huang HY, Lee CL, Wang HS, Soong YK. 2011;254:181–91. The direct antiglobulin test (DAT, direct Coombs test) should be negative (see chapter on laboratory testing for lead). Even now, lead poisoning and toxicity are still significant issues that need to be addressed. Wheeler and Bailer [38] indicated that the “average-model” method often failed to adequately cover the true BMD when a linear or near linear dose-responses was modeled. For centuries, lead toxicity has been one of the most significant preventable causes of neurologic morbidity from an environmental toxin. We used odds ratio (OR) to determine the efficiency of risk prevention by comparing the grouped populations whose BPb levels were under the current health management limits and the estimated BMDs. Figure 3a shows that BMD10 were strongly correlated with BMDL10 for male (r = 0.69) and female (r = 0.82) workers. Félix PM, Almeida SM, Pinheiro T, Sousa J, Franco C, Wolterbeek HT.

A heavy metal, lead … Hemolysis may also lead to elevated LDH and bilirubin. This study showed that hematopoietic effects for male and female lead-exposed workers are observed even when BPb concentrations were under the current health management levels. Risk contribution analysis indicated that female workers in the assembling group contributed a significant high risk to the total population, with a contribution proportion of 31.5%. Adverse hematological effects are some of the manifestations of lead poisoning in lead workers. Int J Hyg Environ Health. Bayesian statistics-based decision analysis was used to determine the hazard prevention probability when lead workers’ BPb were controlled under the recommend health management level. All authors read and approved the final manuscript. SHC is an assistant research fellow in Institute of Labor, Occupational Safety and Health, Ministry of Labor. Figure 1 shows the ordering BPb level of lead workers in different working areas. 1). Therefore, stringent PEL and personal hygiene strategy should be considered to reduce exposure to airborne lead. However, the highest hazard contribution in male lead workers was estimated at only 9.5% in the grinding group. The study used non-identifiable data in all data analysis. If a hemolytic anemia is in the differential, haptoglobin, lactate dehydrogenase (LDH), and bilirubin can be useful. This study found that BPb-related hematological effects of anemia were consistent with previous studies [16, 22]. Chung-Min Liao. Shaik AP, Jamil K.

The article discusses common contributory etiologies ranging from nutritional to infectious causes for iron deficiency anemia in the pediatric age group. Cumulative lead dose and cognitive function in adults: a review of studies that measured both blood lead and bone lead. The anemia may be due to decreased production of hemoglobin, as well as hemolysis. Overall, the BMD models provide more accurate and precise value by using the computational approach, which considers the uncertainty from the epidemiological information and mathematical models. CAS  Computational approaches are a useful research tool in the health risk assessment of chemical exposure, including heavy metal [36]. Thus, the 8-h time-weighted-average airborne lead concentrations must not exceed 2.1 μg/m3. Lead Poisoning Guide: Causes, Symptoms and Treatment Options Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. statement and We found that the highest hazard occurrence probability was in male grinding workers with median HI of 1.00 (95% CI: 0.39–1.80) (Fig. 2014;840547.

The observed average BPb levels were much lower than the current health management limits in this study. Risk Anal. Therefore, lead workers might suffer from illnesses associated with low-level lead exposure. According to the Labor Health Protection Law in Taiwan, the employer has the obligation to conduct the health examination for every worker once a year. Int J Hyg Environ Health. The inhaled/ingested lead can transport to the heart, bones, intestines, kidneys, reproductive, and nervous systems, causing tissue-specific adverse effects [3, 4]. The model averaging method has also been widely applied to dichotomous dose-response relationships in a variety of risk assessment contexts such as occupational and epidemiological studies [38, 39]. Recently, lead condensate in exhaled breath was also shown to be a suitable non-invasive biomarker of occupational exposure in recent years [2]. Hoboken: Wiley; 2009. Cite this article. Haptoglobin scavenges free hemoglobin and is low in hemolytic anemia. 1,  n Lead poisoning and anemia are both detected by a blood test. We found that BPb level at 15 μg/dL could be used as a suitable health management limited rather than 10 μg/dL. Exposure routes of lead uptake in the workplace include ingestion and inhalation of inorganic lead. 3b). The recommended standards for female workers were set at 10 and 15 μg/dL. Therefore, the major sources of lead exposure may come from dust, fume, and poor personal hygiene including eating and smoking through contaminated hands. 1| y). Environ Health Perspect.
