A Bussels-Ixelles police spokesperson confirmed initial laboratory findings that indicated the substance inside the envelopes was harmless and most likely flour.
Initial laboratory tests indicate the substance can reduce arsenic concentrations from 2,400 μg/L to only 10 μg/L within an hour.
In wastewater samples, the fluorescence peak at around Ex/Em = 390 440 nm/442–508 nm indicates the humic substances (Table 1), which is the specific fluorescence indicator of azo dye in TWW (Li et al. 2015).
Notes The red text indicates the emitted substances and green text represents mitigation technologies.
The measurement objects are also connected to substance objects, indicating the measured substance, e.g. an image may represent the 2D distribution of a metabolite.
The magnitude of the change in current indicates the concentration of the substance – the fraction of DNA molecules that change conformation is proportional to the number of cocaine molecules in the sample.
Reason - size of zone indicates the effect of the substance tested on the growth of the specific bacterium.
Additionally, the comparison of the results from the library indicates the presence of substances homologous in 54.22% to paromomycin sulfate, a compound that is a derivative of the aminoglycoside antibiotics in the ex-LMS isolated from C. unicolor.
The comparison of the FT-IR spectrum for c-EPL with the library data indicates the presence of substances with 46.68% homology to dihydroxystreptomycin, a derivative of aminoglycoside antibiotics.
Thus, the methanol extract or fraction, expressing good biological capacity, indicates that the substance with powerful biological effect exists in this extract and it have to be isolated and purified to confirm its pharmacological and medical use.
