We studied the relationships between mercury content of Squacco Heron (Ardeola ralloides) chick body-feathers and nestling age, hatching order (seniors-juniors) and growth parameters, and the date of feather sampling in the Axios Delta, northern Greece, in 1993 (n = 75 chicks) and 1994 (n = 80). Mercury levels were not significantly correlated with chick age in either year of the study. Most of...

Female birds whose bodies contain environmental contaminants produce eggs with shells that are likewise contaminated, making bird eggshells appropriate indicators for monitoring toxins. Common include organic mercury compounds, especially methylmercury, which known to bioaccumulate and biomagnify in the food chain. Black storks (Ciconia nigra) predominantly consume fish thus at risk high intake...

In the last decades the awareness of scientists, decision makers and citizens about the ubiquitous and toxic nature of mercury in the environment has considerably grown. The complexity of the environmental problem related to mercury is increased because of the volatile nature of this metal, which results in global dispersion through the atmosphere and deposition in the sea and freshwater bodies...

Mercury pollution poses risks for both human and ecosystem health. As a consequence, controlling mercury pollution has become a policy goal on both global and national scales. We developed an assessment method linking global-scale atmospheric chemical transport modeling to regional-scale economic modeling to consistently evaluate the potential benefits to the United States of global (UN Minamat...
