“…This present study for Co-occurrence in sheep feces was lower than recordings of Abrahams (2013). Our work for Co amount in sheep blood was lower than the investigations by Tarhan et al (2016). The value of Co in blood of cow was found similar with the ndings by Abdel-Salam et al (2013).…”

Background: The aim of study was accessing the cobalt (Co) and lead (Pb) contamination in soil, forages and animals. The heavy metal ions bioaccumulation and escalating transfer to food chain has become main concern for mankind. Nevertheless, they play crucial role in organismal metabolism, however exceeding threshold level causes toxicity or even system failure. Since the plants are the main source of nutrition supply and carbohydrates for animal metabolism, therefore mankind exposure risk to food chain heavy metal toxicity increases significantly. Method: To highlight toxicity levels and exposure risk we designed this field study in the nearby areas of district Mianwali, Punjab, Pakistan during different seasons. and carried out samplings of soil, native flora. While following research ethics we collected samples of blood, hair and feces from domestic herbivore animals. Traditional wet digestion was carried out in available laboratory facilities, Pb and Co heavy metal concentrations were analyzed with atomic absorption spectrum. With emphasis on health risk index (HRI) and bio-concentration factor (BCF), we also draw attention to pollution load index (PLI), daily intake of metal (DIM), Health Risk Index (HRI) and Enrichment factor (EF). Results: Our findings revealed high Pb concentration (5.29-9.84 mg/kg) in forage during season 1. While our findings indicate concentrations of metal in different seasons. When the Co concentration in forages was 0.238 to 0.492 mg/kg and Pb was found in the range of 5.29-9.84 mg/kg). Soil samples showed higher level of (PLI) Pollution load index. Bio-concentration of cobalt and lead was (0.447- 1.106 and 0.717- 1.152 mg/kg) respectively. Conclusions: Bio-concentration factor and pollution load index for Co and Pb was noticed significantly higher than 1. Whereas enrichment factor (EF) was under permissible limit for both metals, daily intake metal (DIM) and no harmful health risk concentration was found. Therefore, wide-scale regular monitoring for heavy metal risk assessment on seasonal basis are highly recommended to avoid or minimize further contamination.

“…The tear film is composed of 98% water and 2% electrolytes, mainly sodium (144–146 mEq/L) and chlorine (128–144 mEq/L), and also proteins, including albumin, metal-carrying immunoglobulins IgA and IgG, and beta and gamma globulins (ceruloplasmin, transferrin, lactoferrin, and mucin) [ 46 ]. However, data on their trace element composition, and particularly trace metals, is sparse [ 47 ]. Studies using proteomic technologies have linked tear fluid proteins to specific diseases [ 48 ], suggesting that tears, along with cerebrospinal fluid, may be a source of potential biomarkers [ 49 ].…”

We aimed to evaluate the types and concentrations of trace elements in tears of individuals living in urban and rural environments using particle induced X-ray emission (PIXE) and the possible association with exposure to air pollution and suggest a novel method for tear-based biomonitoring studies. This cross-sectional pilot study comprised 42 healthy subjects, 28 living in a rural area and 14 in an industrial city. Tears were collected with Schirmer paper and characterized by PIXE. Trace element concentrations from both eyes were averaged together with environmental pollution data. Main outcome measures were between-group differences in types and concentrations of trace elements in tears and comparison to environmental data. The rural group included 12/28 men, mean age 45.2 ± 14.8 years. The urban group consisted of 11/14 men of mean age 27 ± 5.9 years. Six rural and all urban were active smokers. Air pollution data showed more toxic elements in the rural environment. On PIXE analysis, chlorine, sodium, and potassium were found in similar concentrations in all samples. Normalizing to chlorine yielded higher values of aluminum, iron, copper, and titanium in the rural group; aluminum was found only in the rural group. The higher levels of certain trace elements in the rural group may, in part, be a consequence of exposure to specific environmental conditions. No direct association was found with air pollution data. PIXE is useful to analyze trace elements in tears, which might serve as a marker for individual exposure to environmental pollutants in biomonitoring studies.

“…Each measurement was performed three times and averages were used for the analysis. Results were expressed in microgram per milliliter (ppm = µg/mL) and mg/L of serum (Tarhan et al, 2016;Aslan et al, 2018;Ates Alkan et al, 2019).…”

Obesity is the most common metabolic disorder defined as excessive adipose tissue accumulation in the body. Elements and minerals are crucial for biological metabolism. There have been limited studies based on the relationship between elements/minerals and obesity in dogs. The study was aimed to evaluate possible alterations of selected serum elements/minerals -copper (Cu), iron (Fe), zinc (Zn), selenium (Se), chromium (Cr), nickel (Ni), calcium (Ca), phosphorus (P), magnesium (Mg), boron (B), cobalt (Co) and aluminum (Al)- in obese dogs. The study groups were categorized as obese group (n:20) and controls (n:10) with different breeds and genders due to body condition scoring system cared under similar conditions fed with dry commercial food once daily. Serum elements/minerals in serum were analyzed by using inductively coupled plasma-optical emission spectrophotometer (ICP-OES). Obese dogs had statistically higher serum Fe levels compared with healthy controls. A positive correlation was found between serum levels of Cr-Ni; Cu-Mg; Cu-Se; Mg-Se; Mg-Ca; Mg-P; B-Co; B-Ca; Ni-Co; Co-Ca and Ca-P in obese dogs. It has been accepted that obesity is a pro-inflammatory process priorly initiating in adipose tissue. Higher serum Fe levels in obese dogs might be related with inflammation during the obesity process. Moreover, the strong correlations among other discussed elements/minerals even with no statistical alterations of serum levels in obese dogs should be elucidated with further studies. Elements and minerals might be evaluated as biomarkers for the determination of effects of obesity in dogs.
