Cryptosporidium Soil Extraction by Filtration/IMS/FA Compatible with USEPA Method 1623.1

High contamination of soil with Cryptosporidium oocysts in public places of Tabriz

Background & Aim: Cryptosporidium is zoonotic coccidian parasite that causes severe diarrhea in humans and animals worldwide. This study aimed to evaluate the soil contamination rate with Cryptosporidium oocysts of different public places in Tabriz, west of Iran. Methods: In this cross sectional study, 260 soil samples were collected by stratified sampling from 20 parks, 20 primary schools, 20...

Cyanide extraction from contaminated soil: a method comparison

Soils on sites of former manufactured gas plants are usually contaminated with iron-cyanide complexes. We investigated the extraction of cyanide from 23 contaminated soils by three methods, which are prescribed by the German Federal Soil Protection Act and Ordinance: the soil-saturation extract with water, SSE, with a very narrow soil:solution ratio; the so-called S4 water extract with a soil:s...

Method detection limits of PCR and immunofluorescence assay for Cryptosporidium parvum in soil.

We determined and compared the method detection limits (MDLalpha) of a PCR and an immunofluorescence assay (IFA) for detection of Cryptosporidium parvum oocysts in soils. Based on the MDLalpha and the quantitative nature and stability of the IFA, PCR analysis is not a useful screening step for soil studies of oocyst transport.

Fractionation of arsenic in soil by a continuous-flow sequential extraction method.

Batch sequential extraction techniques for fractionating metals or metalloids in soils are time consuming and subject to several potential errors. The development of a continuous-flow sequential extraction method for soil As is described and assessed, having the benefits of simplicity, rapidity, less risk of contamination, and less vulnerability to changes in extraction conditions compared with...
