AbstractAnthropogenic pollution is known to negatively influence an organism’s physiology, behavior and fitness. Epigenetic regulation, such as DNA methylation, has been hypothesized as one mechanism to mediate such effects, yet studies in wild species are lacking. We first investigated the effects of early-life exposure to the heavy metal lead (Pb) on DNA methylation levels in a wild population of great tits (Parus major), by experimentally exposing nestlings to lead at environmentally relevant levels. Secondly, we studied the effects of heavy metal exposure in a population close to a copper smelter, where birds suffer from pollution-related decrease in food quality. For both comparisons, the analysis of about million CpGs covering most of the annotated genes, revealed that regions enriched for developmental processes showed pollution-related changes in DNA methylation, but the results were not consistent with binomial and beta binomial regression. Our study indicates that post-natal anthropogenic heavy metal exposure can affect methylation levels of development related genes in a wild bird population.

ObjectivesTo investigate the associations between heavy metal exposure and serum ferritin levels, physical measurements and type 2 diabetes mellitus (DM).DesignA retrospective cohort study.SettingChangwon, the location of this study, is a Korean representative industrial city. Data were obtained from medical check-ups between 2002 and 2018.ParticipantsA total of 34 814 male subjects were included. Of them, 1035 subjects with lead exposure, 200 subjects with cadmium exposure and the 33 579 remaining were assigned to cohort A, cohort B and the control cohort, respectively. Data including personal history of alcohol and smoking, age, height, weight, the follow-up duration, haemoglobin A1c (HbA1c), fasting blood sugar (FBS), ferritin levels, and lead and cadmium levels within 1 year after exposure were collected.Primary outcome measureIn subjects without diabetes, changes in FBS and HbA1c were analysed through repeated tests at intervals of 1 year or longer after the occupational exposure to heavy metals.ResultsIn Cohort A, DM was diagnosed in 33 subjects. There was a significant difference in lead concentrations between the subjects diagnosed with DM and those without DM during the follow-up period (3.94±2.92 mg/dL vs 2.81±2.03 mg/dL, p=0.002). Simple exposure to heavy metals (lead and cadmium) was not associated with DM in Cox regression models (lead exposure (HR) 1.01, 95% CI: 0.58 to 1.77, p 0.971; cadmium exposure HR 1.48, 95% CI: 0.61 to 3.55, p=0.385). Annual changes in FBS according to lead concentration at the beginning of exposure showed a positive correlation (r=0.072, p=0.032).ConclusionOur findings demonstrated that simple occupational exposure to heavy metals lead and cadmium was not associated with the incidence of DM. However, lead concentrations at the beginning of the exposure might be an indicator of DM and glucose elevations.

Background: Oxidative stress is a unified concept for the assessment of metabolic status of buffaloes affected by a cocktail of heavy metal exposure from environment and it may significantly affect the metabolic profile and milk production during summer season. The present study aimed at evaluation of effect of probiotic (Saccharomyces cerevisiae strain 1026) and amla powder (Embilica officinalis) supplementation on levels of heavy metals, antioxidant status, oxidative stress in lymphocytes, metabolic profile and milk production of summer stressed buffaloes exposed to environmental heavy metal pollution. Methods: Twenty summer stressed lactating Murrah buffaloes of the same age group, close parity and in early lactation from the heavy metal exposed area were divided into two groups: Control (without supplementation) and Treatment group (supplemented with Saccharomyces cerevisiae1026) @ 50 billion live cells / animal /day and Amla powder @ 86 mg/kg body weight for 30 days. Blood and milk samples were collected from both the groups on the day of starting of supplementation (i.e. day 0) and on there after days 15 and 30 and analyzed for antioxidant status, metabolic profile, milk yield and quality.Result: Oral supplementation of probiotic and amla powder for 30 days improved the antioxidant status, metabolic profile and milk production of summer stressed buffaloes residing in heavy metal exposed area. The percentage monetary gains from buffaloes fed probiotic and amla powder was 13.68% more as compared to control.
