A high concentration of radioactive cesium has been found in a range of land animals and insects in areas around the site of the Fukushima nuclear plant accident, providing a clue to a mechanism of radioactivity accumulation in the food chain, a study showed Saturday.
According to a survey by the Tokyo University of Agriculture and Technology and Hokkaido University, over 6,700 becquerels per kilogram of cesium 137 was detected in a frog captured in Nihonmatsu, Fukushima Prefecture, some 40 kilometers west of the crippled nuclear plant.
Yale 360: The ecologist David Skelly has found that pollution is leading to limb deformities and the creation of “intersex” frogs

For the last two decades, strange things have been happening to frogs. Some frog populations have high rates of limb deformities, while others have high incidences of what is known as “intersex” — traits associated with both males and females, such as male frogs whose testes contain eggs.
David K. Skelly, professor of ecology at the Yale School of Forestry & Environmental Studies, set out to discover what was causing these deformities, which some researchers were attributing to the use of an agricultural pesticide called atrazine. Skelly launched an experiment in ponds throughout Connecticut, studying frogs in four landscapes: forests, agricultural areas, suburbs, and cities. And what he found was surprising — the highest rates of deformities were not occurring in and around farmlands, but in cities and suburbs.
