35、tual framework of the bioavailability of contaminants in soils and soil materials, and to provide a guidance for the selection of methods able to be standardized for the measurement of bioavailability. Bioavailability was thus defined according to three successive steps:a) “environmental availabilit

36、y”;b) “environmental bioavailability”;c) “toxicological bioavailability”.The environmental bioavailability is consequently a prerequisite to the assessment of the toxicological bioavailability and is directly related to the impact of pollutants on major functions of soil in the ecosystem and more pa

37、rticularly to habitat and retention functions.Environmental bioavailability can be estimated with either chemical or biological methods. In the case of trace elements, chemical methods are usually the cheapest, easy to perform, and some of them are already standardized at national or international l

38、evel (e.g. ISO 19730). However, chemical methods which, strictly speaking, measure the environmental availability in soils have to be correlated with biological measurements before being used as indicators of environmental bioavailability. Whatever chemical methods are employed, none are designed pe

39、r se to address the diversity of responses observed among different plant species or cultivars which can be attributed to a) the uptake behaviour of plants (i.e. sensitive, tolerant, accumulator, or hyper-accumulator of trace elements) and/or b) the ability of plants to alter the biological, physica

40、l and physical-chemical properties of their “bio-influenced zone” at the soil-root interface, i.e. the so-called rhizosphere. It could alternatively, be suggested to apply chemical methods directly to the rhizosphere but the sampling of the rhizosphere is definitely too tedious to be applied routine

41、ly.For biological methods, four standardized biotests account for rhizosphere processes as they are based on soil-grown plants (ISO 11269-1, ISO 11269-2, ISO 17126, and ISO 22030). However, these were only designed to predict trace element phytotoxicity, i.e. the toxicological bioavailability. In th

42、ese biotests, roots grow directly in the soil, therefore requiring a tedious washing procedure to reliably measure trace elements accumulated in the roots. Indeed, the amount of trace elements accumulated in shoots of non-accumulator plant species is not sufficiently sensitive to be used for assessi

43、ng the environmental bioavailability of trace elements compared to the amount accumulated in the whole plant, roots included. Thus, there is still a need to develop biological methods accounting for rhizosphere processes and enabling to include the root compartment in order to properly estimate the

44、environmental bioavailability of trace elements to plants.Consequently, the present International Standard introduces a biotest based on the growing of roots in contact with the soil but without penetrating it. Although this experimental design is partly artificial, it enables a fair comparison of t

45、he bioavailability of trace elements between tested soils. In addition, the end point measured can be more directly related to the measurement of the environmental availability than any end point based on the measurement of toxicity.4DIN EN ISO 16198:2015-04 EN ISO 16198:2015 (E) 1 ScopeThis Interna

46、tional Standard specifies the plant-based test, hereafter called the biotest. It enables estimation of the environmental bioavailability of trace elements to plants either basically as the concentration in shoots and roots or in a more integrative way as the net uptake flux in plants. The biotest pr

47、ocedure includes two successive steps: (i) a pre-growth of plants in hydroponics and (ii) a growth of plants in contact with soil samples. The concentration in shoots and roots as well as the net uptake flux of trace elements in plants are determined at the end of the second step of the biotest proc

48、edure.This biotest is applicable to the assessment of environmental bioavailability of trace elements to plants, more particularly to agricultural plants, in soils or soil materials under oxic conditions, considering that three plant species (cabbage, Brassica oleracea; tall fescue, Festuca arundina

49、cea; tomato, Lycopersicon esculentum; 7.1) are suggested in the standardized biotest procedure, but additional target-plant species can also be used (see 7.1, Annex A), and the standardized biotest procedure is validated for a range of trace elements including arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn), but additional trace elements can also be accou
