“…This analytical calculation is summarized as follows. (9) The number of moles of oxygen necessary to completely burn 1 kg of gasoline were calculated with Equation ( 10 (12) The total amount of exhaust gas (exh) produced from burning 1 kg of gasoline was calculated as the sum of nitrogen and argon of the comburent air and CO 2 and water produced through the combustion of gasoline: m exh per kg of gas = m CO 2 per kg of gas +m H 2 O per kg of gas +m N 2 per kg of gas + m Ar per kg of gas = 15.839 kg exh kg gas (13) The volume (V) of the exhaust per kg of gasoline at a certain temperature can be calculated knowing the density (ρ) of the various components at that temperature (Table 2). The temperature of 500 K for the exhaust was chosen for the comparison between syngas and gasoline combustion.…”

“…Another pollutant produced through combustion is CO [10], one of the main contributors to air pollution due to its high toxicity [11]. Furthermore, sulfur-containing fossil fuel combustion is responsible for most of the sulfur dioxide (SO 2 ) content in the atmosphere [12]. SO 2 is a toxic gas and one of the major components of acid rain [12].…”

Climate change, environmental degradation, and biodiversity loss are prompting production systems to shift from a fossil-based economy to a circular bio-based one. In this context, biomass gasification is a promising alternative to fossil fuels that can contribute to power generation in rural communities and remote areas as well as provide a sustainable source of energy for developed countries. In this work, exhaust gas emissions (CO, NOx, and SO2) of two syngas-fueled micro-scale generators were measured. The first system is a commercial biomass gasifier genset, whereas the second is composed of a laboratory-scale gasifier prototype and a portable petrol generator. For this second facility, emissions were measured both running on gasoline and on syngas. The comparison was performed both on the pollutant concentration and on their cumulative amount. This comparison was made possible by calculating the exhaust gas flow by knowing the combustion stoichiometry and fuel consumption. The results showed a much lower pollutant concentration running on syngas compared to gasoline. In particular, considering the best configurations, every cubic meter of exhaust gas released running on syngas contains about 20 times less CO and almost one-third less NOx compared to gasoline. Moreover, the cumulative amount of emissions released was also considerably lower due to the lower exhaust gas flow (about 25%) released running on syngas.

“…Underground plants are generally affected by the fertility of the soil and the temperature at which they are grown then fertilizers are added to manipulate the soil fertility (Hamilton et al 1998). Pollution is increasing rapidly, so it is important to measure the concentration (Kapitány et al 2020).…”

Environmental problems were faced, and one of them is the accumulation of Sulphur and its compounds in the atmosphere and through the atmosphere, it accumulates in the soil and then the underground plants. In the atmosphere Sulphur it is present in the form of aerosols and acid precipitation. Volatile Sulphur compounds are released by the combustion of fossil fuels and volcanic eruption also produces Sulphur oxides. Deficiency of Sulphur produces paling of plants and denaturing of some enzymes that are then fulfilled by using the fertilizers of Sulphur. Soil also has an adverse effect when particulate matter or Sulphur aggregates in the plants and their physiological and biological development is retarded. Most of the industrial processes contain Sulphur compounds like thiol, thiophene, oxides of Sulphur etc. Structural and chemical mutation occurs when particulate substances induce into the plants and productivity and efficiency of that plant is reduced. The impact of acid rain in places with high quantities of mixed air pollutants has yet to be determined. Acid inputs appear to be affecting several techniques in field soils. These must be measured in terms of plant output. SO2 enters the leaves via stomata and quickly dissolves in Apoplastic water, producing mostly Sulphite (SO3)-2, bisulphite (HSO-3), and H+ ions. SO2 phytotoxicity has been attributed to Sulphite and bisulphite ion interactions with different chemicals. If the quantities are not too high, most leaves can detoxify Sulphite and bisulphite by oxidizing them to less harmful Sulphate ions via a series of processes. SO2 absorbed by foliage may undergo reduction conversion, including absorption into organic Sulphur compounds and release from the leaves as H2S. The oxidizing or reducing route of SO2 in plants is determined by plant species, soil Sulphur content, SO2 amount and persistence, and plant growth conditions.

“…Recently, many researchers reported the different lead analysis in water and human blood samples [13]. The various techniques such as flame atomic absorption spectrometry (F-AAS) [14,15], the electrothermal atomic absorption spectrometry (ET-AAS) [16], the inductively coupled plasma mass spectrometry(ICP-MS), the microwave plasma atomic emission spectrometry(MP-AES) [17,18], the gas chromatography mass spectrometry GC-MS [19] and laser-induced breakdown spectroscopy (LIBS) [20] were used for lead determination in different matrixes. Due to difficulty of matrixes and interferences, the extraction/preconcentration method for lead determination in blood samples is used.…”

The exposure of lead in workplace air and human workers of battery manufacturing factory was evaluated determined by nanotechnology since 2019-2020. Human whole blood (HWB) for subject and healthy peoples (25-55, Men, 40 N) and workplace air (40N) was prepared based on NIOSH sampling. 10 mL of HWB samples added to 20 mg of mixture ionic liquid/ ligand ([HMIM][PF6]/APDC) modified on graphene oxide nanostructures(GONs) at pH=6. After sonication, the lead ions separated/extracted by dispersive ionic liquid solid phase micro extraction (DIL-SPME) and determined by flame atomic absorption spectrometry (F-AAS). All air samples in workplace were analyzed based on NIOSH process. The results showed us the negative correlation between Pb concentration in human blood subject and healthy peoples (r=0.24). The range concentrations of lead in human subject, healthy peoples and workplace air were obtained 193.4-543.7 µg L-1, 85.6-175.9 µgL-1 and 44.7-81.5 µgm-3, respectively. The LOD, linear rang, enrichment factor(EF) and RSD% were achieved 1.25 µg L-1, 5.0- 310 µg L-1, 19.6 and less than 5% by procedure. The method was validated by standard reference material (SRM), the electrothermal atomic absorption spectrometry (ET-AAS) and ICP-MS analyzer for human samples.
