Soil Quality Standards: Science or Science Fiction

Open Problems in the Derivation of Soil Quality Criteria from Ecotoxicity Experiments

“…Rather, they represent the fields where, according to the author's view, some progress has been made recently or is to be expected shortly. Given the great need for development of soil protection measures (Vegter et al, 1988;Denneman & Robberse, 1990) established criteria should be subjected to periodic revision when some of the problems in soil ecotoxicology have been solved.…”

Petroleum contamination in groundwater/air and its effects on farmland soil in the outskirt of an industrial city in China

“…The values in all groundwater (except I1-1M, I3-3M, and I4-5 M) were also above the risk-based removal level (500 μg L − 1 ) established by the Netherlands for petroleum hydrocarbon contaminated groundwater. It was an interim quality standard, setup as a first step of an interactive approach to establish a standard fully based on cause-effect relations (Vegter et al, 1998). The TAH values were higher than 1.0 mg L − 1 at I2M, I3M, I6M (except I3-3M and I6-2M), and I4-2M in May 2009 and all groundwater collected in October 2009.…”
