metals in Tai Lake were obtained.Both risk quotients and joint probability methods were used for evaluation of ecological risk to aquatic organisms.Cu and Zn posed the greatest risks to aquatic organisms in comparison to other metals.Ecological risk of Cu and Zn was greater than previously thought...
and X-ray powder diffraction, and supported by electron microscopy and theoretical modeling, we present direct evidence that zinc formate is the principal observable reactive intermediate, which in the presence of hydrogen converts into methanol. Our results indicate that the copper–zinc alloy ...

To evaluate the changes in zinc and copper concentrations in breast milk and maternal blood during lactation, milk and blood samples were obtained from 80 lactating women during the period between 2 and 201 days of lactation. Zinc and copper concentrations were measured by atomic absorption spectroph...
The relationship between serum levels of zinc and copper and sexual maturation were analyzed in 2291 9-18-yr-old Finnish girls and boys. Development of pubic hair, breasts, and genitalia were used to grade maturation according to Tanner's classification. Serum zinc and sexual maturation were not...
