“…Various plants and crops have been shown to be hyperaccumulators of heavy metals [5,10,11]. Studies have shown that over 80% of heavy metals could be ingested via the food crops [12]. According to Kikuchi et al [13] (pp.…”

Heavy metal pollution is not only a hazard to living organisms but also an important worldwide environmental concern. Experiments were performed to investigate the physiological mechanisms of magnetic (Fe 3 O 4 ) nanoparticles (nano-Fe 3 O 4 ) mitigation of the toxicity of heavy metals (Pb, Zn, Cd and Cu) in wheat seedlings. All the Petri dishes with germinating seedlings (1d) were covered, sealed with parafilm, and placed in a dark growth chamber. All parameters (seedling growth inhibition, heavy metal accumulation, enzymatic activities, and reducing effects of nano-Fe 3 O 4 on heavy metal toxicity) were analyzed only after five days. The results showed that the tested heavy metals significantly affected the growth of wheat seedling by decreasing root length, shoot length and even death at 10 mM concentration in the case of Cd and Cu. Heavy metals exposure also showed that superoxide dismutase (SOD) and peroxidases (POD) activities decreased significantly when the malondialdehyde (MDA) content was significantly higher in wheat seedlings. Addition of magnetic (Fe 3 O 4 ) nanoparticles (2000 mg/L) in each heavy metal solution (1 mM) significantly decreased the growth inhibition and activated protective mechanisms to reduce oxidative stress induced by heavy metals in the wheat seedlings. The reducing effects of nano-Fe 3 O 4 against heavy metals stress could be dependent on the increase in the enzyme activity (SOD and POD). Their protective role was confirmed by the decrease in MDA content. The alleviating effect of nano-Fe 3 O 4 is associated with their adsorption capacity of heavy metals.

“…Cadmium might constitute a serious health hazard for large groups of the population because it can bioaccumulate (Marzec and Schlegel-Zawadzka 2004). The half-life of Cd in the human body is 10 to 30 years (Nawrot et al 2006).…”

“…[3][4][5][6][7] In Ukraine and Poland, blood mercury concentrations have been low and stable over a period of at least 12 years. [8][9][10] Nevertheless, global mercury emissions may be increasing because of burning of coal and fuel oil especially in Asia. 11 In vitro studies have shown that mercury induces DNA breaks in spermatozoa 12 and lead to decreased sperm motility, dysfunction and viability.…”

Several animal studies indicate that mercury is a male reproductive toxicant, but human studies are few and contradictory. We examined semen characteristics and serum levels of reproductive hormones in relation to environmental exposure to mercury. Blood and semen samples were collected from 529 male partners of pregnant women living in Greenland, Poland and Ukraine between May 2002 and February 2004. The median concentration of the total content of mercury in whole blood was 9.2 ng ml 21 in Greenland (0.2-385.8 ng ml 21 ), 1.0 ng ml 21 in Poland (0.2-6.4 ng ml 21 ) and 1.0 ng ml 21 in Ukraine (0.2-4.9 ng ml 21 ). We found a significantly positive association between the blood levels of mercury and serum concentration of inhibin B in men from Greenland (b50.074, 95% confidence interval (CI)50.021 to 0.126) and in an analysis including men from all three regions (b50.067, 95% CI50.024 to 0.110). The association may be due to beneficial effects of polyunsaturated fatty acids (PUFAs), which are contained in seafood and fish. No significant association (P.0.05) was found between blood concentrations of mercury and any of the other measured semen characteristics (semen volume, total sperm count, sperm concentration, morphology and motility) and reproductive hormones (free androgen index (FAI), follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone and LH3testosterone) in any region. In conclusion, the findings do not provide evidence that environmental mercury exposure in Greenlandic and European men with median whole blood concentration up to 10 ng ml 21 has adverse effects on biomarkers of male reproductive health.
