Pollutants are emitted into the atmosphere by human activity and are later deposited partly in the hydrosphere such as in ponds and lakes. Sediments in the hydrosphere retain the environmental pollutants over a long time. Using this property of sediments, many studies have revealed the historical changes in environmental pollution by sampling columnar sediment cores from the hydrosphere and estimating the deposition age of the core materials.The sources of lead can be determined using lead isotope ratios, which vary depending on the source mine. The measurement of lead isotope ratios in sediment cores is therefore very useful for identification of the historical source of environmental lead pollution.Lead in sediments is however derived from both anthropogenic sources and natural input and the lead isotope ratios of the sediment therefore consist of values averaged from the two sources. The present review describes a useful method of extracting anthropogenic lead from sediment and estimating its isotope ratios. This method can be used to estimate the isotope ratios of anthropogenic lead at the time of deposition in the environment of the sampling site. It also enables comparison of the isotope ratios of anthropogenic lead in one sediment with those in other sediments.

The report “Healthy Japan 21” sets out Japanese public health targets for the year 2010. Under the item of “Nourishment/eating habits”, detailed numerical values are given for the whole human lifespan. For adult women, in particular, the pregnancy period is important, as poor nourishment and bad habits can sow the seeds of lifestyle-related disease. It is important to lay the foundations for healthy eating habits and dietary education activity early on. Now, the Dietary Education Law, enforced in 2005, has provided backing for such activity, and dietary education activities specific to each region are being developed. By teaching children the value of home cooking, it is important to nip lifestyle-related disease in the bud.
