“…Also, tobacco is indigenous to many countries such as India, Middle‐East, South‐East Asia, and Americas . The tobacco samples (spit tobacco, gutkaas, and paan masalas) were found enriched with the presence of mineral elements such as Na, K, Ca, Cl, Mg, P, Cu, Fe, and Zn and traces of toxic and heavy elements particularly As, Cr, Co, Al, Ni, and Br . In our study, the presence of some heavy and toxic elements such as Al, Cu, Ni, Br, and Sr was observed in the stone samples of patients having chewing habitats of tobacco and habitats of meats products which are good and potential sources of these heavy and toxic elements .…”

The presence of toxic and heavy elements particularly Ni, Br, and Cu only in KS3 stone sample may be due to the chewing habitats as chewing samples were reportedly enriched with these toxic elements (as mentioned earlier).…”

Kidney stone is the most painful and prevalent urological disorder of the urinary system throughout the world. Thus, analysis of kidney stones is an integral part in the evaluation of patents having stone disease. Spectroscopic investigations of stones provide an idea about the pathogenesis of stones for its better cure and treatment. Hence, the present work targets multispectroscopic investigations on kidney stones using Fourier transform infrared (FTIR) and wave dispersive X-ray fluorescence (WD-XRF) spectroscopy which are the most useful analytical methods for the purpose of bio-medical diagnostics. In the present study, FTIR spectral method is used to investigate the chemical composition and classification of kidney stones. The multicomponents of kidney stones such as calcium oxalate, hydroxyl apatite, phosphates, carbonates, and struvite were investigated and studied. Qualitative and quantitative determination of major and trace elements present in the kidney stones was performed employing WD-XRF spectroscopy. The wide range of elements determined in the kidney stones were calcium (Ca), magnesium (Mg), phosphorous (P), sodium (Na), potassium (K), chlorine (Cl), sulfur (S), silicon (Si), iodine (I), titanium (Ti), iron (Fe), ruthenium (Ru), zinc (Zn), aluminum (Al), strontium (Sr), nickel (Ni), copper (Cu), and bromine (Br). For the first time, ruthenium was detected in kidney stone samples employing WD-XRF in very low concentration. Our results revealed that the presence and relative concentrations of trace elements in different kinds of stones are different and depend on the stone types. From the experiments carried out on kidney stones for trace elemental detection, it was found that WD-XRF is a robust analytical tool that can be useful for the diagnosis of urological disorders. We have also compared our findings with the results reported using XRF technique. The results obtained in the present paper show interesting prospects for FTIR and WD-XRF spectrometry in nephrolithiasis. Copyright

“…Johnston et al and Kumar et al reported that an Fe‐deficient diet might change the metabolism of the hepatic enzyme that subsequently enhances the level of cholesterol in gallbladder bile to develop the cholesterol crystal. Moreover, the central aggregates of Ca compounds consist of hard foreign bodies that may cause ulceration of the gall bladder mucosa, inflammation, and microscopic hemorrhage . Deposition of metal Fe in gallstones may also be due to this releasing phenomenon .…”

“…Gallstones also show the presence of Pd, which may be due to the different geographical locations of gallstone, the dietary differences of the patients, and environmental pollution issues.The occurrence of heavy and toxic metals such as Pb, As, and Sr in stone GS1 may be attributed to the chewing habits of tobacco and habits of smoking of the corresponding patients. This has been a matter of a lot of research, and several reports conclude that tobacco and smoking products are possible factors resulting in the presence of heavy and toxic metals . Therefore, it has been concluded that these kinds of dietary habits should be avoided, particularly by patients of gallstone disease, to prevent gallbladder cancer.…”

Gallbladder cancer, which is associated with the heavy metal toxicity, is one of the most dangerous malignancies. High occurrence of gallstones in the gallbladder is a well-recognized risk factor for gallbladder cancer. Accumulation of heavy and toxic metals in the biliary system is one of the main causes of gallstone formation and leads to gallbladder cancer if it remains untreated. In this work, we investigate heavy and toxic metals in gallstones to identify their association as potential risk factors for gallbladder cancer. Detection and quantification of the heavy and toxic chemicals present in gallstones are important to define etiopathogenic factors that, in turn, are useful to identify preventive and therapeutic strategies. We quantified the heavy metals in gallstones collected from patients of different age groups and dietary habits. We carried out chemical composition studies of trace and heavy metal elements present in gallstones by applying Fourier transform infrared (FTIR) spectroscopy and wavelength-dispersive X-ray fluorescence (WD-XRF) spectrometry. We also compared our experimental results with the results obtained from atomic absorption spectroscopy, as well as values previously reported in literature. These findings demonstrate the potential of WD-XRF spectrometry and FTIR spectroscopy as important emerging diagnostic tools in the field of gastroenterology.

The heavy metal in tobacco has been widely concerned for the toxicity and bioaccumulation. Heavy metal in tobacco is of extremely related with the corresponding concentration in soil. One hundred soil samples were collected from five typical tobacco cultivated areas to evaluate the environmental quality and health implications. The inductively coupled plasma mass spectrometry was employed to determine the concentrations of heavy metals (As, Cd, Cr, Cu, Hg, and Pb). The geo‐accumulation index and potential health risk assessment were performed to investigate the environmental quality and health risk. The concentrations of As, Cd, Cr, Cu, Hg, and Pb are ranged from 0.40 to 112 mg/kg, 0.07 to 4.22 mg/kg, 5.52 to 338 mg/kg, 3.40 to 64.5 mg/kg, 0 to 1.62 mg/kg, respectively. The concentrations of heavy metals are various among the five different typical cultivation areas. The elevated concentrations of heavy metals in the selected soils suggesting that these heavy metals may be derived from anthropogenic sources i.e. industrial and agricultural activities. The results shown that the soils in the Jingxi, Longlin, and Debao County are posed to a moderately to heavily contamination for Hg and Cd. The noncarcinogenic and carcinogenic effects (except Lingyun County) caused by heavy metal exposure is regarded as acceptable. The Lingyun County soil should be paid more attention due to the unacceptable level of carcinogenic risk. As, Cd, Hg, and Cr are regarded as the priority control metals. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 483–488, 2017
