Sentence examples for contaminants elements from inspiring English sources

The results of the tests conducted with an inlet flow ten times higher than design ones (500 L/d) showed that the pilot plant is able to work until contaminants elements are three times higher of the design quantity.

The instrument has been designed in order to explore whether laser-induced X-rays can replace conventional X-ray sources in the examination of wafer surfaces for traces of contaminant elements by X-ray fluorescence spectrometry.

Briefly, after cleaning and washing the toenails to remove external contaminants, trace elements were quantified at the Trace Element Analysis Core (Dartmouth College, NH, USA), using inductively coupled plasma-mass spectrometry (Hopkins et al, 2004).

Changes in the quality of groundwater resources are related to the presence and concentration of contaminants, especially trace elements such as arsenic, boron, fluoride and vanadium.

By swapping conventional copper electrodes for a titanium electrode and water dielectric, modified surfaces free of trace element contaminants were produced.

Here INP are investigated using batch reactor systems over a range of pH for the treatment of water containing multi-element contaminants specifically U, Cu, Cr and Mo, selected to provide site-specific analogues for leachants collected from the Lişava mine, near Oraviţa in South West Romania.

Results showed that a number of trace element contaminants present in the original CO2 sorbent and gasifier fuel samples were also present in the flue gas from both the CO2 capture and gasification processes, implying that integration of the technologies may result in enhanced contamination in the final gaseous product.

One of the main risks is the potential alteration of groundwater quality by the intrusion of contaminants such as trace elements.

In general, it was confirmed that the release of most potentially clogging elements and contaminants can be reduced or avoided by preventing oxygen from entering the aquifer, even at elevated temperatures.

Soil amendment with drinking water treatment residuals (DWTRs) has been shown to limit the uptake of metal contaminants, effectively immobilizing these elements within the soil; however, DWTRs possess a strong specific affinity for P and soil amendment with DWTRs can reduce P availability, thereby inducing plant P deficiencies and restricting growth.

Any surveillance program designed today to monitor feed safety would have to include sampling and testing for microbiological parameters, a whole range of different contaminants, including heavy metals/undesirable elements, Persistent Organic Pollutants ["POPs"], and natural toxins and different feed additives.
