CAS  The proportions of lead working population with abnormal hematological indicators were estimated >10% in each job category. Nigeria Niger J Clin Pract. J Occup Health. Correspondence to Lin JL Lead level in seminal plasma may affect semen quality for men without occupational exposure to lead Reprod Biol Endocrin. Therefore, stringent PEL and personal hygiene strategy should be considered to reduce exposure to airborne lead. Although gasoline and paint are no longer made with lead in them, lead is still a health problem. 2009;51:1–12. Hematological indicators have the reference ranges in the clinical medicine that can be used to diagnose the conditions of hematopoietic system. Risk assessment results demonstrated that lead workers are likely to work in unsafe workplaces. 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. Therefore, the major sources of lead exposure may come from dust, fume, and poor personal hygiene including eating and smoking through contaminated hands. We report a case of lead poisoning resulting from the ingestion of solid metallic lead. A 24 year old patient was admitted for abdominal pain and microcytic anemia. Grover P, Rekhadevi PV, Danadevi K, Vuyyuri SB, Mahboob M, Rahman MF. 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. 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. Flora G, Gupta D, Tiwari A. All identifications such as name and job id were removed by the lead factories and Taiwan Institute of Labor, Occupational Safety and Health. Payton M, Hu H, Sparrow D, Weiss ST. Low-level lead exposure and renal function in the normative aging study. A critical review of biomarkers used for monitoring human exposure to lead: advantages, limitations, and future needs. Lead poisoning can cause anemia. Lead poisoning can cause anemia. All 218 female workers were working in lead battery factories. Our mission is to provide practice-focused clinical and drug information that is reflective of current and emerging principles of care that will help to inform oncology decisions. LDH is present in red cells, and hemolysis causes release into the plasma. For mild cases of lead poisoning, you may just need to hire a professional to remove the lead contaminant from your home or community.

YJL is a postdoctoral research fellow in Department of Bioenvironmental Systems Engineering, National Taiwan University. The absorption of lead can cause iron deficiency and may further cause anemia. Although the ORs and hazard prevention probabilities of a BPb level at 25 μg/dL were higher than those of a BPb level at 35 μg/dL, it seems that the improving efficiency had reached the theoretical level. Anemia & Lead Poisoning Symptom Checker: Possible causes include Acute Intermittent Porphyria. Our research framework can also be applied to assess other lead induced-adverse health effects in exposed population. 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. 1 are the ratio of normal and abnormal hematological indicators in the subpopulation number of n 0| y) ~ beta (y This study found that BPb-related hematological effects of anemia were consistent with previous studies [16, 22]. 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). Neurotoxicity and biomarkers of lead exposure: a review. 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. For female workers, assembling and packaging work groups had relatively higher hazard occurrence probabilities of 80% and 60% with the median HIs of 1.48 (0.47–2.67) and 1.32 (0.43–3.16), respectively. Ann Occup Hyg. Digestive problems. LDH is present in all tissues, including red cells, so elevations are consistent with hemolysis but very nonspecific, as any cellular damage may affect levels. (DOCX 32 kb), Fitted quantal model for male lead-exposed workers. PubMed  Other symptoms associated with lead poisoning are covered in the chapter on laboratory testing for lead. Therefore, we used hematological indicators to represent BPb-induced anemia. Chin Med Sci J.

In particular, does your patient take any medications - OTC drugs or Herbals - that might affect the lab results. Anemia associated with chronic lead exposure is a result of both interferings with heme biosynthesis and by decreasing red blood cell survival. 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. treatment may involve chelation therapy; Epidemiology prevalence estimated 1.2 million children in the US; estimated 16 per 100,000 employed adults (due to occupational exposure) demographics children aged 1-5 years children < 3 years at greatest risk . All 533 male workers were working in the lead battery, lead stearate, and lead bullion factories, respectively. Summary of the Benchmark dose (BMD) models used in this study. PubMed Central  The BPb was significantly correlated with all hematological indicators, including Hct (r = −0.38; p < 0.001), Hgb (r = −0.40; p < 0.001), RBC (r = −0.18; p < 0.05), MCV (r = −0.19; p < 0.01), MCH (r = −0.22; p < 0.01), and MCHC (r = −0.18; p < 0.05) for male workers (Fig. Lead poisoning is a type of metal poisoning caused by lead in the body. Agency for Toxic Substances and Disease Registry, ATSDR, Toxicological Profile for Lead, US Department of Health and Human Services Public Health Service, 2007. 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. 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. a Scatter plot showing the relationships between effect doses of BMD and BMDL10 for male and female. The observed average BPb levels were much lower than the current health management limits in this study. Keramati MR, Manavifar L, Badiee Z, Sadeghian MH, Farhangi H, Mood MB. here. Lead poisoning is what happens when lead builds up in your body over a period of months or years. 2012;10:91. Lead is also harmful to adults, and may cause: Problems during pregnancy. A child who swallows large amounts of lead may develop anemia, severe stomachache, muscle weakness, and brain damage. J Hazard Mater. However, the highest hazard contribution in male lead workers was estimated at only 9.5% in the grinding group. It is often associated with a decrease in some trace elements (iron, zinc, copper) and an increase in heavy metals as lead. Estimation of the posterior distribution of ORs can be simply obtained by simulating the distribution of f(π 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. The brain is the most sensitive. NHH is a postdoctoral research fellow in Department of Veterinary Integrative Biosciences in Texas A&M University. PubMed Google Scholar. CML is a distinguished professor in Department of Bioenvironmental Systems Engineering, National Taiwan University. 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. Biased exposure-health effect estimates from selection in cohort studies: are environmental studies at particular risk? 1) where Y Are There Any Factors That Might Affect the Lab Results? 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. A risk-based probabilistic model was used to characterize the potential hazard of lead poisoning for job-specific workers by hazard index (HI). 2014;122:1160–5. Environ Health Perspect. The abnormal risk of anemia indicators for male and female workers could be reduced, respectively, by 67–77% and 86–95% by adopting the suggested BPb standards of 25 and 15 μg/dL. Through Cochran-Armitage trend test, our results found that hematological indicators had significant dose-response trend with BPb concentration in male workers, including Hct (χ2 = 3.336; p < 0.01), Hgb (χ2 = 1.741; p < 0.05), MCV (χ2 = 3.879; p < 0.001), and MCH (χ2 = 3.343; p < 0.001) (see Additional file 2: Tables S2 – S5). Assessment of exposure to metals in lead processing industries. Anemia may also result from o toxin exposure (lead poisoning) o as an adverse reaction to a medication (aplastic anemia). Furthermore, a long-term follow-up investigation is urgently needed to characterize lead-associated adverse health effects. To determine whether the estimated critical values of BPb can be used as the novel limit for health management, this study successfully applied a Bayesian analysis approach integrated with MC simulation to estimate the uncertainty and reliability of risk control efficiency. Wignall JA, Shapiro AJ, Wright FA, Woodruff TJ, Chiu WA, Guyton KZ, Rusyn I. Standardizing benchmark dose calculations to improve science-based decisions in human health assessments. 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]. CAS  Ahmad et al. Learn vocabulary, terms, and more with flashcards, games, and other study tools. All authors read and approved the final manuscript. In Taiwan, the Occupational Safety and Health Act suggests that pregnant women should stop working in the current lead-exposed workplace and prohibits them to work until one year after childbirth. 2014;122:499–505. The funding body had no role in the design of the study, the collection, analysis, and interpretation of data, or the writing of the manuscript. The distributions of the abnormal number in hematological indicators are shown in Table 2. Therefore, we assumed that the cumulative BPb that sourced from workplace or other area can be associated with the change of the hematological indicators. Data are however available from the authors upon reasonable request and with permission of the lead factories in Taiwan. Koh DH, Nam JM, Graubard BI, Chen YC, Locke SJ, Friesen MC. Ann Occup Hyg. Assessing airborne PM-bound arsenic exposure risk in semiconductor manufacturing facilities. Flora et al. Google Scholar. Our results suggest that the current BPb limit needs to be better characterized to better protect the health of lead-exposed population. In addition, what follow-up tests might be useful? 1,  n Some of the effects are permanent. Furthemore, there is no evidence of a safe exposure level for renal and cardiac effects associated with exposure to lead [31, 32]. Based on MC simulation, the BMDs were depicted as a probability density function of normal distribution that average BMD10 were 48.39 ± 11.58 (mean ± sd) and 10.26 ± 1.98 μg/dL for male and female workers, respectively (Fig. Even at low levels, lead can affect a child's mental and physical growth. J Hazard Mater. The model averaging BMD10 estimates were 53.5 (BMDL10: 40.5), 60 (44.5), 37.8 (22.1), and 42.0 μg/dL (28.8) for Hct, Hgb, MCV, and MCH for male workers, respectively (Tables S2 – S5). If a hemolytic anemia is in the differential, haptoglobin, lactate dehydrogenase (LDH), and bilirubin can be useful.

The inhaled/ingested lead can transport to the heart, bones, intestines, kidneys, reproductive, and nervous systems, causing tissue-specific adverse effects [3, 4]. Microcytic anemia, long considered an effect of lead poisoning, may in fact result from coexisting iron deficiency. 2015;12:S7–17. There are several types of hemolytic anemia, such as sickle cell disease and thalassemia Anemia related to insufficient … The adverse health effects of lead exposure have been known for centuries. The hazard prevention probabilities were estimated 32.0% and 22.9% under unadjusted and adjusted scenarios, respectively. This study suggests that current BPb standard needs to be better understood for the application of lead-exposed population protection in different scenarios to provide a novel standard for health management.

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. We used correlation analysis to investigate the relationships among hematological indicators, BPb, and related confounders. Lead Poisoning and Anemia Associated With use of Ayurvedic Medications Purchased on the Internet — Wisconsin, 2015. 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. By contrast, our study found that BPb-related hematological effects may display gender-specificity due to inter-individual variability. Each simulation was carried out with 10,000 iterations to assure the stability of its probability distribution. Further, our BMDL10 estimates were consistent with their results, which ranged from 33 to 49 μg/dL. Int J Hyg Environ Health. Springer Nature. 4). Genotoxicity evaluation in workers occupationally exposed to lead. 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%. Lead Causes Neurological Damage in Children. 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). This study could not investigate and control the other possible sources of lead exposure outside the work and get the complete information on previous experience of lead-related work.

Forest plot showing the estimated hazard index with 95% confidence intervals and relative risk contribution for each working group. This study focuses on the dose-response relationship between BPb concentration and the hematological indicators from regular health examination. 1, b Uncertainty is a key factor in risk assessment that can influence the precision of risk estimation [21]. Environ Health Perspect. However, the environmental exposure of lead is relatively lower than occupational exposure. Statistics and regressions of this study were conducted in the open source language R (Version 3.1.1, The R Foundation for Statistical Computing). Risk Anal. Wheeler MW, Bailer AJ. The estimated BMDs were further treated probabilistically by considering the BMD10 and BMDL10, representing the mean and lower levels of 95% confidence interval (CI), respectively. 1, respectively. Terms and Conditions, Hoboken: Wiley; 2009. The model averaging and the corresponding BMD and BMDL are potentially biased in low-dose scenarios. Review of the peripheral smear is crucial. Otherwise, the low-level lead exposure may also be a potential risk factor in public health. 0 + a Review of the literature suggests that clinical manifestations of chronic poisoning by solid lead in adults are extremely rare.

Anemia risk in relation to lead exposure in lead-related manufacturing. Your doctor will run tests to determine whether you have lead poisoning and how severe it is. Haematological assessment of occupational exposure to lead handlers in Enugu urban, Enugu state. Based on the Labor Health Protection Law, lead workers were asked to complete the questionnaire of special physical and the medical examination that included five items of demographic data, working experience, past medical history, living habits, and self-perceived symptoms. BMC Public Health Bilirubin is a breakdown product of hemoglobin and becomes elevated as hemoglobin is released. We thank Dr. Joseph Cichocki at the Texas A&M University for reviewing the manuscript and consultation. Evaluating temporal trends from occupational lead exposure data reported in the published literature using meta-regression.

Environ Health Perspect. i is the proportion of lead-exposed worker in the specific job category. The anemia of lead intoxication is hypochromic and normo -or microcytic with associated reticulocytosis. Lead can cross the placental barrier, which means pregnant women who are exposed to lead also expose their unborn child. The goal of this study was to examine the association between lead exposure and anemia risk among factory workers in Taiwan. 2007;51:665–78. Lead is especially dangerous for children.

Breathing in dust that contains lead can also cause it. CSH searched the literature, reviewed the literature and made substantial contributions to conception and design. HI > 1 implies that unacceptable health risk of anemia will occur for lead-exposed workers in the specific working group and HI < 1 indicates acceptable health risk with the proportion of health effect <10%. 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. Adverse hematological effects are some of the manifestations of lead poisoning in lead workers. PubMed  The p-value <0.05 was considered to be statistically-significant. Even now, lead poisoning and toxicity are still significant issues that need to be addressed. Anemia associated with lead poisoning.
