We analyzed soil for As, Pb, and Hg and estimated the soil metal concentration at the residential sites where the woman and children lived during pregnancy and early childhood using a Bayesian Kriging model.
To analyze soil samples for PAHs, 2 g of dried soil was mixed with Hydromatrix© (Agilent Technologies, Mississauga, ON), and each sample was spiked with known concentrations of US EPA 16 PAH Cocktail C (Cambridge Isotope Laboratories, Tewksbury, MA).
The team is also planning to analyze soil collected last summer for all the animal and plant DNA it can detect, not just for specific microbial genes.
It will consist of an orbiter and several landers, one of which will analyze soil samples to search for traces of life on Mars.
As Curiosity carries on, researchers plan to analyze soil and sediment samples for organic material and to team up with Mars orbiters to search for methane patterns in the atmosphere.
We analyzed soil samples for extractable calcium (Ca), magnesium (Mg), potassium (K), cation exchange capacity (CEC), pH, bulk density, A-horizon depth, total carbon (C), and nitrogen (N).
Dr. Ingham runs a company called Soil Foodweb Inc., which analyzes soil and diseases for growers and helps wean them from chemical agriculture.
This paper describes a methodology based on particle image velocimetry for analyzing soil motion from a sequence of images.
Similar to sampling of the herbaceous species, soil samples at a depth of 0 20 cm were taken for analyzing soil physical and chemical properties.
Similar to sampling of the herbaceous layer, nine soil samples (one per 1-m2 quadrat) at a depth of 0 20 cm were taken using a soil auger for analyzing soil physical and chemical properties, yielding a total of 216 samples (two locations × three invasion levels × four plots × nine quadrats).
