Blood lead concentrations in children with iron deficiency anemia: a systematic review and meta-analysis.

Iron deficiency is the most common nutritional disorder detrimental to the behavior, cognitive performance, immune system, and physical growth of infants and preschool- and school-age children. Iron deficiency anemia (IDA) increases children's susceptibility to some metals, including the highly toxic lead (Pb), but the character of this relationship is still disputed. Thus, this study aimed to review and meta-analyze the association between the IDA and blood lead levels (BLL) among children, based on papers indexed by international scientific databases and published up to September 2021.

Relationship between gestational diabetes and serum trace element levels in pregnant women from Eastern Iran: a multivariate approach.

The prevalence of gestational diabetes mellitus (GDM) has increased over the recent decades. Exposure to environmental contaminants may be a risk factor for the development of GDM, but this is heavily dependent on particular circumstances. Studies on various areas linking various factors are therefore needed.

Metal Risk Assessment Study of Canned Fish Available on the Iranian Market.

Iran is the largest fishery producer in the region reaching nearly 1 million tons. Fish provide a good many nutrients that are beneficial for our health. Due to significant deposits of xenobiotics in the water environments, however, fish may also be a source of non-essential metals, causing a variety of disorders.

Cadmium and chromium levels in water and edible herbs in a risk assessment study of rural residents living in Eastern Iran.

In arid and semi-arid regions of Iran, water is supplied by qanats, underground channels where pollution is suspected, but unestablished. The aim of this study was thus to run a risk assessment study regarding the levels of cadmium (Cd) and chromium (Cr) in qanat water and edible herbs (Adiantum capillus-verenis, Chara globularis and Plantago lanceolata) growing in qanats in 14 villages in South Khorasan Province in Iran between April and August 2018. Samples were collected in qanats from the same sampling points, and after mineralization in nitric and perchloric acids were analyzed for metal concentrations by means of atomic absorption spectrometry.

Urinary Metal Levels with Relation to Age, Occupation, and Smoking Habits of Male Inhabitants of Eastern Iran.

In low-income and middle-income countries such as Iran, smoking is becoming increasingly popular, especially among young people. This has led to additional exposure to a variety of substances, including metals which may exert a toxic influence and lead to severe diseases. In order to evaluate the influence of smoking on metal concentrations, a case-control study of levels of metal in urine was carried out in smokers (n = 64) and non-smokers (n = 35) from the city of Birjand (Iran).

Metal concentrations in archaeological and contemporary mussel shells (Unionidae): Reconstruction of past environmental conditions and the present state.

Freshwater mussels are widely used in the monitoring of pollution because they are filter-feeding, long-lived animals that tend to accumulate metals in their shells. The temporal scale of such studies can reach thousands of years, since the composition of shells preserves them against decay. This allows us to reconstruct past environmental conditions and to compare current environmental conditions to those prevalent thousands of years ago.

Caffeine strongly improves motility parameters of turkey spermatozoa with no effect on cell viability.

The purpose of this study was to evaluate the impact of caffeine on turkey spermatozoa during in vitro incubation. Experimental samples were prepared by diluting the raw semen with nine different concentrations of caffeine - from 0.078125 mg/mL to 10 mg/mL.

Biogenic and Risk Elements in Wines from the Slovak Market with the Estimation of Consumer Exposure.

Wine consumption delivers macroelements and microelements necessary for the proper metabolism. On the other hand, wine can be an important source of toxic metals. The aim of this study was to estimate the concentrations of Ca, Cd, Cu, Fe, Hg, Mg, Ni, Pb, and Zn in the Slovak and non-Slovak wines.

Levels of Metals in Kidney, Liver, and Muscle Tissue and their Influence on the Fitness for the Consumption of Wild Boar from Western Slovakia.

Due to environmental pollution, wild animals are exposed to various pollutants. Some game animals, such as wild boars are used by people for food, but their meat is not evaluated regarding pollution transfer, since they are unavailable on the official market. The aim of this paper is to present the concentrations of chosen metals (Cd, Co, Cu, Hg, Pb, and Zn) in the kidneys, liver, and muscles of wild boars (n = 40) hunted in eastern Slovakia, as derivatives of physiological distribution and anthropogenic pollution.

Relationship between air pollution and metal levels in cancerous and non-cancerous lung tissues.

We aimed to check the relationships between levels of metals (Ca, Cd, Cu, Fe, Hg and Zn) in cancerous and non-cancerous lung tissues and their link to air pollution, expressed as particulate matter (PM) concentrations. The study also examines the influence on metal concentration in the lung tissue of patients' sex and the distance of their homes from the nearest emitter. We found that the general pattern of ascending concentrations in tumor tissue was as follows: Hg < Cd < Cu < Ca < Zn < Fe.

Trace element concentrations in feathers of five Anseriformes in the south of the Caspian Sea, Iran.

Birds are susceptible to environmental changes, which make them particularly important as indicators of environmental contamination, including metal concentrations. In the present study, the concentrations of arsenic (As), cadmium (Cd), chromium (Cr), iron (Fe), lead (Pb), manganese (Mn), nickel (Ni), and zinc (Zn) in the tail and flight feathers of greylag goose, mallard, pintail, pochard, and wigeon were investigated from the south of the Caspian Sea in Iran by the electrothermal atomic absorption spectrometry (ET-AAS) method. The trend of metal concentrations in both types of feathers of all the examined species was as follows: Fe < Zn < Mn < Cd ∼ Cr ∼ Ni ∼ Pb < As.

Cadmium, lead and mercury concentrations and their influence on morphological parameters in blood donors from different age groups from southern Poland.

Due to industrial development, environmental contamination with metals increases which leads to higher human exposure via air, water and food. In order to evaluate the level of the present exposition, the concentrations of metals can be measured in such biological materials as human blood. In this study, we assessed the concentrations of cadmium (Cd), mercury (Hg) and lead (Pb) in blood samples from male blood donors from southern Poland (Europe) born in 1994 (n=30) and between 1947 and 1955 (n=30).
