Methods for the extraction of PCR-quality DNA from environmental soil samples by using pairs of commercially available kits were evaluated. Coxiella burnetii DNA was detected in spiked soil samples at <1,000 genome equivalents per gram of soil and in 12 (16.4%) of 73 environmental soil samples.

Soil transmitted helminth (STH) infection are endemic in developing countries. A study was carried out of sewage farms, streams and vegetables to determine the sources and routes of STH infection in Sanliurfa, Turkey. Stool samples from farmhouse inhabitants as well as soil and vegetable samples from the gardens were collected and examined. In addition, water samples from streams and vegetable ...

The transferability of a visible and near-infrared (VNIR) model for soil organic matter (SOM) estimation in riparian landscapes is explored. The results indicate that for the soil samples with air-drying, grinding and 2-mm sieving pretreatment, the model calibrated from the soil sample set with mixed land-use types can be applied in the SOM prediction of cropland soil samples (r 2 Pre = 0.66, R...

INTRODUCTION This study assessed the microbial quality of clay samples sold on two of the major Ghanaian markets. METHODS The study was a cross-sectional assessing the evaluation of processed clay and effects it has on the nutrition of the consumers in the political capital town of Ghana. The items for the examination was processed clay soil samples. RESULTS Staphylococcus spp and fecal col...

The operation of the new FAIR accelerator facilities will inevitably produce some amount of radioactivity in the surrounding earth and water, mainly caused by neutron radiation. Although previous experience from the GSI and other accelerators [1] suggests that the resulting radiation exposure to the population will be close to zero, we need to do detailed investigations for the planning of the ...

This study was conducted to develop fundamental relationships between soil properties from three representative Florida soil orders and their spectral characteristics. The ultimate goal of this work is to develop a real–time soil property sensor for use in effective farm management. A total of 270 samples collected from the three representative soil orders (Alfisol, Entisol, and Ultisol) in Flo...

Abstract. Developing a phosphorus sensing system using UV, VIS and NIR provides a non-contact, cost & time effective, less laborious measurement of phosphorus (P) concentration in a soil sample. The determination of soil spectral signatures in the Lake Okeechobee basins in Florida improves the prediction accuracy of calibration models produced for the determination of soil P concentration for O...

Leptospira is an important re-emerging zoonotic human pathogen, disseminated by sick and carrier animals, water and soil. Weather calamities, such as flooding or cyclones favour the spreading of these bacteria. To check a potential role of natural water and soil in the persistence and spread of Leptospira on the territory of eastern Poland, 40 samples of natural water and 40 samples of soil wer...

A critical appraisal of single-step extraction procedures of chromium species from soil was done in terms of their selectivity towards Cr(III) and Cr(VI) species. Samples of natural mineral and organic soil and samples of soil enriched with different chromium compounds of various solubility (in liquid or solid form) were used to simulate contamination of soil by liquid and solid wastes. The eff...
