In particular, two types of sampling scheme will be discussed. First, schemes for areas that have received a (low-level), constant and widespread input of contaminants, e.g. irrigation of waste water, spreading of sewage sludge, aerial fall-out, contaminated fertiliser, are amenable to ...
Here we present some of the most promising active and passive sampling methods for assessing the bioavailable and volatile fractions of inorganic and organic contaminants.
The first two will usually be in the context of a defined region, no particular form of spatial variation is implied, the answers will be global ones for the region as a whole, and classical (design-based) sampling and estimation should serve well. The third question demands local answers ...
In this thesis multi-phase flow models are used to study the flow behavior of liquid contaminants in aquifers and of gases that are injected below the groundwater table for remediation purposes. Considered problems are redistribution of ... Dijke,M. I. J. van Marinus Izak Jan - [S 被引量...

and sample handling and preservation. We found that the random sampling design can be used to collect a representative sample. Stainless steel shovels or soil augers were the most common tools for collecting topsoil, from 0 to 30 cm. Deep soil samples, of more than 100 cm depth, can only ...

Sampling, sample preparation and analyses At the beginning of the experiment, a grass sample representative of the offered sward was taken in the experimental plot, out of the grazing circles, then washed in warm water to evacuate soil traces before drying. Soiling of the sward was evaluated fro...
