Analysis of some heavy metals (Cd and Pb) in the Şanlıurfa province using Feral pigeon blood samples

Certain studies have reported various insulin resistance responses to ambient heavy metal pollution, but few have reported such responses to occupational heavy metal pollution. Even fewer have demonstrated a relationship between mixture effects of heavy metals and insulin resistance in welding workers. Overall, we recruited 53 welders and 48 administrative staff from a shipyard located in northern Taiwan. Personal exposure to heavy metals was monitored for PM2.5 and urine. Blood samples from each participant were collected from the antecubital vein after fasting. Urine samples from each participant were collected in the same period as blood samples. The geometric mean levels for chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), and cadmium (Cd) in the PM2.5 of the personal breathing zone and urinary Mn of welders were significantly higher than those in administrative staffs. Ambient Cr, Co, Ni, and Cu levels in the PM2.5 and urinary Cd were positively related to HOMA2-IR after adjusting for personal covariates (PM2.5-Cr: β=0.036, 95%C.I.: 0.002 to 0.070; PM2.5-Co: β=0.040, 95%C.I.: 0.002 to 0.077; PM2.5-Ni: β=0.054, 95%C.I.: 0.013 to 0.094; PM2.5-Cu: β=0.049, 95%C.I.: 0.010 to 0.088; U-Cd: β=0.209, 95%C.I.: 0.052 to 0.366, respectively). Our findings indicated the PM2.5 metal components and urinary metals were associated with increased insulin resistance in shipyard welders.

The Relationship

Background. The kidney is the first target organ of heavy metal toxicity due to its capacity to reabsorb and accumulate divalent metals. Hemodialysis therapy is used to purify the blood of individuals with impaired kidney function. Objective. The aim of the present study was to evaluate the relationship between dialysis fluid quality and the health of hemodialysis patients. Methods. A field sampling program was conducted to collect blood samples from 320 hemodialysis patients (56% males and 44% females) in order to examine the concentrations of heavy metals that typically occur in municipal water in Baghdad (aluminum (Al), copper (Cu), lead (Pb), and zinc (Zn)), and explore associations with the same metals in dialysis fluid collected from four major dialysis centers in Baghdad hospitals for a period of one year (2018). Results. The results showed that the dialysis fluid quality was not in compliance with international standards. The dialysis fluid in 63% of the samples contained high Al concentrations, while Cu and Zn concentrations were within international standards. Lead concentrations were elevated in dialysis fluid in some hospitals as well. Discussion. The average blood levels of biologically important heavy elements were significantly varied in hemodialysis patients when compared with local reference values. Conclusions. Since both deficiency and excess elements are potentially harmful, the hypothesis that heavy element status affects the risk of adverse clinical outcomes is a worthy investigation. Participant Consent. Obtained Ethics Approval. The study was approved by the Baghdad Ethics Committee of the Iraqi Ministry of Health and Environment. Competing Interests.

The combined effects of heavy metals and parasitic infections on wild rats from Awotan municipal dumpsite in Ibadan city southwest Nigeria were determined. A total of thirty rats were captured from the dumpsite and five rats from a control site using live traps. Rats were identified, weighed and body length measured to determine body condition index. Blood samples were collected from the rats using the cardiac puncture method. Rats were euthanized and dissected to extract various organs (kidney, liver and intestine). Intestinal helminths were extracted, identified and preserved. Blood parasites were identified using Giemsa staining technique of thick and thin films while intestinal helminths recovered were preserved and identified to species level. Organs, intestinal helminths and blood samples were digested and concentrated for heavy metals (Fe, Cu, Cr, Cd, and Pb) using Atomic Absorption Spectrophotometry (AAS). Cortisol level was determined using ELISA technique. All statistical significance was at probability value p < 0.05. Three species of rats were captured, Rattus rattus, Rattus novergicus and Cricetomys gambianus. The mean ± sd of the body condition index of the rats from dumpsite and control groups were 1.82±0.17 and 1.59± 0.38 respectively. There were significant differences in the mean values of eosinophils, platelets and white blood cell counts of rats from the two study sites. Overall parasite prevalence in dumpsite and control were 76.6% and 20% respectively. The overall prevalence of parasite species from dumpsite was in the order Hymenolepis diminuta (26.6%) >Monoliformis monoliformis (20%) >Plasmodium spp (20%) >Trypanosoma spp (10%). The mean concentration (mg/kg) of heavy metals in kidney, liver, intestine and blood of wild rats from both dumpsite and control decreased in the order Fe> Cr> Cu> Cd> Pb. Cortisol level was higher in infected rats from dumpsite (351±58.83ng/ml) than in uninfected rats from dumpsite (237.22± 44.46ng/ml), indicating exposure to immune stressors. A higher prevalence of parasitic infection, heavy metal pollution and the elevated cortisol concentrations in infected rats showed that the animals’ health and well-being are compromised.

Due to negligent use and disposal of lead containing sources including acid and alkali batteries with lead conductor, vehicle accumulators in last years, environment has been polluted greatly and it becomes the cause of animal poisoning. Heavy metals are dangerous because of their persistence and toxicity. Soil behaves as a sink of heavy metals by aerial deposition of particles emitted by human activities. The aims of this work were to identify the levels of lead in accumulator processing plant and city areas and animals. A total of 60 blood samples were collected in the vicinity of Ulaanbaatar and measured lead concentrations using equipment LeadCare II. Detection limit of LeadCare II for blood lead concentration ranges between 3.3 and 65 μg/dl. Measurements were made in three replicates using the samples, which were diluted by 10 to 100 fold and about 180 units of analysis was carried out. According to our study lead concentration in blood from livestock populations in the vicinity of Khonkhor lake, Nalaikh district is greater up to 52.9 ppm and the concentration in the soil around the factories is 30 fold higher. High lead content were found in soil and livestock animal blood samples of accumulator processing plant, which have correlated positively between them. But lead concentration in the blood sample from animals, which in areas might be free from lead pollution, was higher than acceptable level. In further studies on contamination resources are required.

Abstract Newcastle disease (ND) outbreak even in the face of vaccination is a common problem in Nigeria. Three Newcastle disease (ND) panzootic were recorded in the past and one of such was caused by feral pigeon fecal contamination of poultry feed materials. The study was designed to investigate the presence of ND antibodies in pigeons slaughtered in three markets in Zaria Nigeria. A total of 1500 Pigeons sera samples were tested across the selected markets, namely: Sabon-gari, Samaru and Tudun-wada markets. Five hundred blood samples were collected from each market. An overall seroprevalence of 22.33% (335/1500) was recorded in this study. Hemagglutination inhibition test revealed that pigeons from Sabon-gari market had the highest seroprevalence of 29% (145/500). Female pigeons had higher seroprevalence of 27.66% (130/470) compared to male pigeons 19.90% (205/1030). Younger pigeons of < 10 weeks old are more prone to ND infection with a seroprevalence of 34.21% (52/152) compared to pigeons > 10 weeks old 20.99% (238/1348). Also, only in Samaru market was there a significant association between ages (P = 0.00) and sexes (P = 0.00) of pigeons and seroprevalence of ND. Therefore, free routine ND vaccination campaign should be launched in the study areas with more emphases targeting the market species in order to mitigate the epidemic cycle of the virus. Moreover, market poultry farmers should be enlightened on the economic significance of the disease and the need to maintain strict biosecurity measures on their market farms.

Aims: Modern industrialization, anthropogenic and industrial activities have increased the risk of human exposure to heavy metals and in turn effecting human health badly. Hundreds of millions of people are globally affected by heavy metal toxicity through contaminated water in one way or. another. In order to find a correlation between the heavy metal concentrations and serum creatinine level, a study was conducted on the inhabitants living near the Hudiara drain suffering from kidney diseases. Study Design: The subjects (n=498) were selected from the vicinity of polluted Hudiara drain to conduct this matched case–control study in 2019-2020. Instrumental techniques were used for the determination of heavy metals and creatinine was determined by using Kit. The correlation between heavy metals and creatinine was checked. Place and Duration of Study: To determine heavy metals and creatinine in blood, samples were collected from the habitants of Hudiara drain and the control group 100Km far from Hudiara drain. Methodology: Blood samples of male subjects with and tested for heavy metals in the blood using atomic absorption spectrophotometer and creatinine level using Creatinine Elisa Kit. The study was conducted in 2020 and included n= 498 healthy volunteers (control) and n=498 effected (suffering from chronic kidney disease). Results: The ANOVA shows the significant difference between two groups i.e. control group and affected group in all traits of the respondents (weight, age, heavy metal values and serum creatinine level). Pearson’s correlation coefficient was calculated for heavy metals and creatinine subjects’ blood samples. It was found that heavy metal levels in subjects have a significant correlation with serum creatinine. The study shows that serum creatinine level has no significant correlation with age, so is independent of age. Conclusion: The concentration of heavy metal contaminants (Cd, Hg, Pb) in the blood of the inhabitants of Hudiara drain flowing in Lahore city, Pakistan is highly polluted by industrial effluents. The effects of higher concentration of heavy metals in the inhabitants of Hudiara drain have been determined in serum creatinine levels. It was observed that high serum creatinine values are found in subjects suffering from CKD.
