Preliminary analysis showed the presence of significant amounts of nine emerging pollutants (order of magnitude of ng/l): trimethoprim, ofloxacin, enrofloxacin, clarithromycin, acetaminophen, diclofenac, caffeine, thiabendazole and carbamazepine; and trace amounts of another two were detected, namely acetamiprid and erythromycin.
Alpha spectrometry analysis confirmed the presence of significant amounts of 239+240Pu and Am in unfiltered trench waters and a lower level of Pu (Table 1).
All these criteria can be used to distinguish a cambic horizon but analysis of thin sections revealed the presence of significant amounts of clay and silt illuvial features.
"Not any kind of significant amounts".
HPLC analysis of both extract indicated the presence of significant amount of vanillic acid along with other phenolic constituents.
EDX analysis in Fig. 3a shows the presence of significant amount of carbon and nitrogen in APTES-modified BNC, while the scanning electron microphotograph in Fig. 3b shows the surface morphology of APTES-modified BNC.
Yet over time, the researchers' analysis suggests, significant amounts of methylmercury could be deposited along the coastline, nearly all of it from fog during the rainless summer months.
Because of the volatility of organic solvents, sample preparation, specifically on-plate sample-matrix mixing, for MALDI analysis of samples containing significant amounts of organic solvent, can be difficult.
The CESS analysis also showed significant amounts of heavy metals, including nickel (43 ppm), manganese (59 ppm), titanium (321 ppm), chromium (67ppm) and copper (55 ppm). Louis and Kumar used energy dispersive X-ray spectroscopy analysis of the red solid and showed that the particles were composed of mostly carbon and oxygen, with trace amounts of silicon and iron.
Our analysis revealed that significant amounts of antigenic switches were clustered over the CHIKV genome (Figure 2a).
