Sentence examples for extracts of soil from inspiring English sources

We observed similar dose-dependent responses when we treated ZEM2S and human cells in vitro with identical aqueous extracts of soil from hazardous waste sites.

A packed capillary liquid chromatography electrospray ionization tandem mass spectrometry (LC ESI-MS/MS) method was deveLC ESI-MS/MSplied to the identification of methodd hydrolysis products in aqueous extracts of soil.

This technique has been adopted widely because it provides information on phosphorus compounds in alkaline extracts of soils or sediments without the need for the complex extraction and sample clean up procedures involved in conventional chromatography.

For example, Huang et al. [15, 16] reported much larger MUP concentrations in M3 extracts of soils fertilized with poultry litter stabilized with alum [(Al2SO4 3·14H2O] than in M3 extracts from soils fertilized with untreated poultry litter.
