Lawn cuttings may also contain contaminations like branches, stones and sand.
From Fig. 4, it is observed that although the sample may contain some unknown contamination that did not interfere with the BSA-GNPs-based sensing system detecting aqueous Hg2+, these experimental results indicate BSA-GNPs-based sensing system can be utilized for analyzing the practical samples.
(A) Selected ion monitoring using specific and selected mass fragments allows the highly selective relative quantification of metabolites in highly complex preparations that may contain unavoidable chemical contaminations.
Illegal alcohols may contain toxins, typically due to contamination by methanol through the action of pectinase in fruit-based liquor [ 40], or from addition of industrial methanol.
The meat from affected animals may contain Salmonella and so cause food contamination in humans [ 4].
First, although swabs may contain antimicrobial agents, the risk of fungal and potentially bacterial contamination may still arise.
This contamination can be expected because slaughtering generates droplets that may contain viral particles and exposes internal organs with potentially high viral loads.
These samples may contain HEV RNA either extrinsically (on the surface) due to cross-contamination during necropsy or intrinsically (within the tissue).
It is generally more contaminated than bathroom GW (Jeppesen and Solley 1994; christova-Boal et al. 1996) and may contain oils, trace elements and chemicals from detergents, soaps and nutrients and can also contain fecal contamination in traces.
