Contaminations contaminate common databases [PDF]
Molecular Ecology Resources, 2020 AbstractThe polymerase chain reaction (PCR) is a very powerful method to detect and identify pathogens. The high sensitivity of the method, however, comes with a cost; any of the millions of artificial DNA copies generated by PCR can serve as a template in a following experiment.

Contaminant, or no contaminant, that is the question [PDF]
QJM, 2010 A 50-year-old male presented acutely to hospital with palpitations of 6 h duration. Electrocardiogram (ECG) showed a supra-ventricular tachycardia and he was treated successfully with intravenous adenosine and discharged thereafter. Three weeks later, he re-presented with intermittent fever over the preceding 4 days.

Effects of stabilizing materials on soil Cd bioavailability, uptake, transport, and rice growth
Frontiers in Environmental Science, 2022 Cadmium, a widespread toxic heavy metal in farmland soils, is harmful to human health. A field experiment was conducted to investigate the effects of biochar and biochar-based fertilizers on soil pH, organic matter, and available Cd, as well as rice Cd ...

Separation and Lithological Mapping of PFAS Mixtures in the Vadose Zone at a Contaminated Site
Frontiers in Water, 2020 Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are persistent organic contaminants of concern to human and environmental health. Several literature reviews and laboratory column experiments have been conducted to determine the transport parameters ...

Monitoring insulator contamination level under dry condition with a microwave reflectometer [PDF]
, 2015 —Build-up of surface contamination on high voltage insulators can lead to an increase in leakage current and partial discharge, which may eventually develop into flashover. Conventional contamination level monitoring systems based on leakage current,

The Contamination of Oysters [PDF]
Epidemiology and Infection, 1920 The Harbour of Poole lies a few miles to the West of Bournemouth. It has an area approximately of 10,000 acres, but there is only a very narrow passage between its waters and the open sea. The width of this bottle-neck entrance is about 250 yards. The last published Admiralty chart gives the rate of the incoming tide through this narrow entrance at 3¼ ...
