Studies of critical concentration distribution features of polluted elements of Cd and As in main soil types of China, such as laterite, yellow brown soil, black soil and sierozem revealed that soil types vary in different zones, so do
their critical concentrations. The critical concentration has a zonal differentiation with the distribution of soil types from south to north and fromm east to west. This coincides with changes of climate zones and soil zones.

This study was undertaken in 1989-90 in response to community concern about the health effects of known high atmospheric lead levels. The paper reports the aspects of the study related to soil-blood level relationships. A southern area
and a northern area are compared. Soil samples and blood samples are analyzed.

The soil pattern of urban areas is strongly influenced by human activities. Urban soils are sinks for the aerial dispersion of pollutants and sometimes sources for environmental hazards. Therefore, the aims of this study are : to analyse
the properties of soils developed from anthropogenic substrates; to investigate the interrelationship of soils in different urban landscapes (inner city, outer area).

A study was carried out on a structured soil in the south-east of Ireland to investigate flow patterns of water in soil. The results provided preliminary evidence for preferential flow in the soil. Nitrate leaching data, from a grazing study, tended
is discussed. Soils having physical characteristics conducive to preferential flow are illustrated.

In this study, background concentrations were determined by analysing soils considered unaffected by man. Soil profile samples were analysed for major and trace element content of the soils developed on the Minette sandstone on the one hand
and those developed on shales on the other hand. Finally, a limited assessment of the mobility of the trace elements was performed. The results show that in the Minette soil samples, these elements are quite immobile and hence of minimal threat
