Cilësia e tokës - Proçedurat e eliminimit për testimin e mëtejshëm kimik dhe ekotoksikologjik të tokave dhe materialeve me bazë toke - Pjesa 4: Ndikimi i pH në eliminimin me shtesë fillestare acid / bazë

Soil quality - Leaching procedures for subsequent chemical and ecotoxicological testing of soil and soil materials - Part 4: Influence of pH on leaching with initial acid/base addition (ISO/TS 21268-4:2007)

Scope

ISO/TS 21268-4:2007 specifies a test method to obtain information on the short- and long-term leaching behaviour and characteristic properties of materials. It applies to the determination of the influence of pH on the leachability of inorganic and organic constituents from soil and soil material, and the ecotoxicological effects of eluates with respect to microorganisms, fauna and flora. The test is not suitable for constituents that are volatile under ambient conditions.
The test procedure specified in ISO/TS 21268-4:2007 produces eluates that are subsequently characterized by physical, chemical and ecotoxicological standard methods.
