Cadmium is an important environmental contaminant. High consumption of chemical fertilizers and industrial activities in recent decades has caused people to be worried about exposure to cadmium. There is no policy for environmental and biological monitoring of exposure to cadmium in the general population in Iran. This study was aimed to review cadmium content in consuming foods and biological samples in Iran, systematically. We developed a comprehensive search strategy and used it to search on Web of Science, Scopus, Science Direct, and Scientific Information Database until 28 December 2016. The totals of 285 articles were identified and finally 31 original papers were selected. Cadmium contamination was found in Iranian food groups such as rice, cereal and legumes, canned tuna fish, vegetables, fruit juice, and egg. This study showed that cadmium amount in 75% of the consumed rice samples (domestic and imported) was higher than the maximum limits approved by institute of standards and industrial research of Iran. Lettuce samples in Yazd were recorded the highest concentration of cadmium compared to other studies. In addition, high amount of cadmium was observed in the blood of the general population. Regarding the cadmium contamination in food and blood samples in Iran, policies must be adopted to reduce exposure to cadmium through different matrices as much as possible.

“…When combined with the questionnaire results, marked variation in BLLs was found to be associated with diet. Previous studies reported that, because of the use of solder during the can manufacturing, canned foods could contain lead at certain levels ranging from 0.18 to 1.40 μg kg −1 (Sheng, 2001;Voegborlo et al, 1999;Yuan and Liu, 1996), and the children's blood lead levels may had a statistically significant dependence (P b 0.05) on the consumption of canned food (Gong et al, 2004). It was found that children at 8 years had a habit of eating canned and tin food, which would bring the lead into the body.…”

Lead exposure in the environment is a major hazard affecting human health, particularly for children. The blood lead levels in the local children living around the largest coking area in China were measured, and the source of blood lead and the main pathways of lead exposure were investigated based on lead isotopic ratios ( 207 Pb/ 206 Pb and 208 Pb/ 206 Pb) in blood and in a variety of media, including food, airborne particulate matter, soil, dust and drinking water. The children's blood lead level was 5.25 (1.59 to 34.36 as range) μg dL −1 , lower than the threshold in the current criteria of China defined by the US Centers for Disease Control (10 μg dL −1 ). The isotopic ratios in the blood were 2.111 ± 0.018 for 208 Pb/ 206 Pb and 0.864 ± 0.005 for 207 Pb/ 206 Pb, similar to those of vegetables, wheat, drinking water, airborne particulate matter, but different from those of vehicle emission and soil/dust, suggesting that the formers were the main pathway of lead exposure among the children. The exposure pathway analysis based on the isotopic ratios and the human health risk assessment showed that dietary intake of food and drinking water contributed 93.67% of total exposed lead. The study further indicated that the coal used in the coking plant is the dominant pollution source of lead in children's blood.

“…Conductivity, pH and dissolved oxygen were determined by combined probes (Hach) directly in the field. Samples of sediments were collected from several locations in the reser- 3 and analyzed by the atomic absorption spectrometer SolaarS with graphite and flame atomization. Other parameters were determined in the laboratory by the cuvette tests (Hach -Lange).…”

“…The contamination of fresh waters by toxic metals has become a matter of concern over the last few decades, dominantly in heavily industrialized and highly populated cities [1][2][3][4]. Toxic metals are typically released into aquatic ecosystems from domestic and industrial waste water and other human activities [5,6], and have devastating effects on the ecological balance of stream and the diversity of aquatic organisms [7][8][9].…”

Levels of selected toxic metals (Cd, Cu, Cr, Ni, Pb, Zn, Mn, Fe and Al) were determined in water, sediment and different species of fish in twelve reservoirs of the Prague metropolitan area. These reservoirs are affected by different types of urban drainage systems, which alter the level and fate (properties, availability, accumulation, toxicity) of toxic metals in the aquatic environment. Measurements of toxic metals were complemented by analysis of basic water quality parameters. Environmental quality standards (EQS) were exceeded in more than 50% of the studied reservoirs for the following chemical parameters: total organic carbon (TOC), chemical oxygen demand (COD) and phosphate (PO 4 3-). These parameters indicate a significant organic pollution and a high eutrophication level. Copper was identified as the most hazardous pollutant among the selected toxic metals in water. Other metals (Zn, Fe, Mn) exceeded the EQS only exceptionally. High concentrations of copper and zinc resulting in exceeded EQS were also identified in the sediment of most reservoirs. In a few cases increased concentrations of chromium, cadmium and lead were exceeded the EQS. A high variability of metal levels was detected in fish species, according to their age and food habits. The highest levels of toxic metals were found in the Kyjský reservoir (Zn, Cu, Ni, Cd and Pb), Strnad reservoir (Zn, Cu, Cr and Fe) and the retention reservoirs Stodůlecký N3 (Zn, Cu and Cr) and Hájecký RN3 (Zn, Cu, Cr and Pb). These reservoirs are highly affected by different anthropogenic activities, such as printing industry, traffic (Prague's ring road) and wastewater treatment plants.
