“…Bioindication provides information about the direct reaction of organisms, communities or ecosystems to natural or anthropogenic changes (Durkalec et al, 2018), since the biota reacts even to minor changes in external conditions and can even predict the geographical origin (Denisova et al, 2008;Franke et al, 2005;Gauthier-Lafaye et al, 2008;Huang et al, 2017;Ilyinskikh et al, 1998;Sheppard, 2011). The concentration of metals in the body of animals and human beings depends, not only on anthropogenic activity (Durkalec et al, 2018), but also on type of diet (Wang et al, 2014;Zhao et al, 2016), physiological specification of organs and tissues (Carpenè et al, 2017), and genetic characteristics of organism (Demirezen and Uruç, 2006).…”

“…Samples of pork meat are studied as an example of food which is widely consumed by the population of studied areas. The chemical content of pork meat as indicator of the environment condition and methods of metals analysis is being actively studied by Russian and international scientists (Demirezen and Uruç, 2006;Huang et al, 2017;Meurens et al, 2012;Nikolic et al, 2017;Wu et al, 2016;Zhao et al, 2016).…”

“…significant factors in the stabilization and intensification of biogeochemical cycles. In this case the chemical composition of meat products is the sensitive environmental indicator that allows us to recognize their geographical origin and industrial influence as an intake of heavy metals (Huang et al, 2017), or nanoparticles (Adam et al, 2015;Pu et al, 2017Pu et al, , 2016.

Different Life Cycle Impact Assessment (LCIA) methods in the impact assessment may lead to disparate results. Those disagreements in LCIA results are mainly linked to differences in the characterization model on a spatial scale. Most models only provide information about large geographical areas, ignoring ecological aspects of regions that can vary in accordance with geological conditions and the industrial influence level. The current investigation proposes an approach to reduce the spatial limitation of impact modeling. Based on the results of analytical investigations carried out by the research group, and taken from the literature, the characterization factor (CF) is recalculated. Among existing LCIA models, the USEtox is taken as the model recommended by the European Union for human health impacts assessment. In the USEtox model calculation, the general bioaccumulation factor is replaced by the regionalized concentration coefficient to obtain the indirect human exposure factor. The modified characterization factor for 5 USEtox geo zones is calculated.

“…However, this method has a very significant disadvantage, which is during the target–laser interaction process, the sample will quickly melt, so the experiment itself must be done in a hurry and may become inaccurate. − Second is with certain pretreatments to reduce the water content in the sample, such as a drying process followed by pelletization of the sample. The treatment of this sample is also very complicated, and the possibility of errors can occur at this stage of the process. − …”

Emission Spectrochemical Analysis of Soft Samples Including Raw Fish by Employing Laser-Induced Breakdown Spectroscopy with a Subtarget at Low-Pressure Helium Gas

Laser-induced breakdown spectroscopy (LIBS) to detect the light elements such as lithium (Li) and boron (B) and heavy elements such as copper (Cu) and lead (Pb) in raw fish samples is reported in this work. This is made possible by understanding that the soft target absorbs recoil energy and as a result, the ablated atoms gushing from the soft target do not acquire sufficient speed to form a shock wave. In order to overcome this problem, we set a subtarget on the back of the soft target so as to produce the repulsion force by which the gushing speed of the ablated atoms is increased, yielding a sufficiently high plasma temperature or sufficiently large thermal energy needed for the excitation of the ablated atoms. Excellent spectral qualities of various soft samples such as margarine, butter, peanut butter, strawberry jam, raw tuna, raw gindara, and raw salmon are presented. Furthermore, a linear calibration curve with a zero intercept is also obtained for Li, Cu, and Pb. The detection limit of Li, Cu, and Pb is found to be around 0.1 mg/L. This modification of LIBS for soft samples by using a subtarget effect clearly promises a rapid and in situ soft sample analysis since there is practically no sample digestion in the analysis.
