Urban soil is the “memory” of cities, as the sequence of deposited materials originates from
the various stages of a city's life cycle, through a complex process of urban soil …

The GEMAS (geochemical mapping of agricultural soil) project collected 2108 Ap horizon
soil samples from regularly ploughed fields in 33 European countries, covering 5.6 million …

全球一致性和权威性地球化学观测数据是资源与环境评价的定量标尺. 中国实施的“全国地球
化学基准计划” 作为“全球地球化学基准计划” 的一部分, 于2008—2014 年实施 …

Applied geochemistry and environmental sciences invariably deal with compositional data.
Classically, the original or log-transformed absolute element concentrations are studied …

In the framework of the GEMAS project, 2211 samples of agricultural soil (Ap, 0–20 cm,
regularly ploughed fields), and 2118 samples from land under permanent grass cover (Gr, 0 …

Lead isotopes are widely used for age dating, for tracking sources of melts, sediments, Pb
products, food and animals and for studying atmospheric Pb contamination. For the first time …

Lead is a toxic heavy metal that has become much more prevalent in the environment since
industrialization and causes considerable health problems. The current study investigated …

Compositional data—and most data in geochemistry are of this type—carry relative rather
than absolute information. For multivariate outlier detection methods this implies that not the …

Over 4000 agricultural and grazing land soil samples were collected for the “Geochemical
Mapping of Agricultural and Grazing Land Soil of Europe”(GEMAS) project carried out by the …

New geochemical data from two continental-scale soil surveys in Europe and Australia are
compared. Internal project standards were exchanged to assess comparability of analytical …
