Laboratory testing of persistent organic pollutants toxicity on soil microbial biomass - application limits, drawbacks and benefits
Original language description
Soil toxicity test with indigenous microflora is based on laboratory incubation of well defined natural soil which was spiked with tested chemical at the beginning of the test. Changes in microbial biomass, its respiration and nitrogen mineralization arerecorded as effect endpoints. This method is well standardized under OECD, US EPA and SETAC guidelines for testing chemicals and pesticides. In our study, selected persistent organic pollutants were tested to identify the applicability of the tests forPOPs effects routine testing. Selected POPs were: toxaphene (pesticide), short chain chlorinated paraffin (industrial chemical), and four aza-PAHs (industrial by-product). Microbial biomas Cbio, basal respiration (BR), substrate induced respiration (SIR), and BIOLOG functional diversity were measured as endpoints after 2 weeks and 4 weeks of exposure. The most sensitive parameter was substrate induced respiration.
