“…Sea waters usually contain 10-15 ng L -1 of thallium. [12][13][14][15][16][17][18] There is a lack of data regarding other attempts to determine the content of thallium in homeopathic drugs, therefore it was not possible to compare the obtained results with other reports.…”

“…13 which allows for medium exchange and circulation ( Figure 1). The system worked under the following conditions: differential-pulse amplitude of 50 mV, step potential of 2 mV, mercury film electrode based on glassy carbon as a working electrode, saturated calomel electrode as the reference electrode, platinum wire as the auxiliary electrode, mercury film deposition period of 10 min using a 0.05 mM mercury(II) solution of nitrate and 0.1 M potassium nitrate.…”

“…13 A sample of the studied pharmaceutical preparations (0.5 g) was placed in a teflon beaker and digested by adding 65% nitric acid and 2.5 mL of 30% hydrogen peroxide. Upon evaporation of the solution the residues were mixed with an additional portion of nitric acid (1 mL), covered with a watch glass and heated for 3 hours.…”

Objectives: The present study is focused on the determination of thallium (I) ions in homeopathic drugs. Methods: The determination was carried out using the Differential Pulse Anodic Stripping Voltammetry (DPASV) technique coupled with the flow-injection measuring system (FIA-DPASV). Results: The thallium content was analyzed in two commercial homeopathic preparations (Thallium aceticum 5CH and 9CH), which include two different concentrations of thallium. It was established, that the mean concentration of thallium in the 5CH drug was at 6.67 ng L -1 in the administered daily dose, whereas in case of 9CH the value was at 2.1 ng L -1 of thallium. Conclusion: The obtained results indicate that the application of the studied homeopathic drugs for medical purposes is not associated with any hazards in terms of possible toxicity due to thallium content.

“…Although its concentration is usually low (at μg per g.of soil), thallium is present in the natural environment in the form of various minerals [24]. The increase in thallium content in plant tissues may be caused by emissions of specific contaminants and their subsequent distribution in the environment.…”

It is estimated that approximately 10 million cigarettes are smoked every minute in the world and that the number of smokers is now about 1.3 billion people [1]. The health hazards associated with smoking tobacco are mainly caused by the presence of numerous chemical compounds. To date, more than 4,000 different chemicals (including hydrocarbons, aldehydes, ketones, and aromatic hydrocarbons) have been isolated from tobacco [2]. These substances also include heavy metals such as lead, arsenic, and cadmium, which are mainly absorbed from the soil and accumulate in leaves. It is believed that the presence of heavy metals in cigarette smoke may be responsible for the loss of health in active and passive smokers. Moreover, exposure to heavy metals associated with smoking is often correlated with cancer incidence and mortality [3][4][5]. Studies show that metal concentrations are higher in pulmonary tissues of lung cancer cases than controls [6].Recent studies have confirmed that, aside from other heavy metals, tobacco may also contain thallium [7]. Thallium is considered to be severely toxic for humans, animals, plants, and microorganisms [8]. It is absorbed through the skin and mucous membranes, spreads rapidly in the body, and accumulates in bones, kidneys, and throughout the central nervous system [9]. The toxic effect of thallium is caused by its similarity to the potassium (I) ion, which results in potassium-associated metabolic process disorders [10]. The toxicity of this element is higher compared to mercury, cadmium, and lead (maximum admissible concentration at 0.1 mg/ml) [8]. It is believed that the maximum dose of thallium should not exceed 15 micrograms, and the LD 50 for humans is 8-12 mgTl×kg -1 [11][12]. A high dose of thallium received over a short period of time may even lead to death. Diagnosis of thallium poisoning is very complicated, therefore its confirmation requires chemical analysis. The symptoms of thallium poisoning in the case of exceeding the maximum permissible doses are: vomiting, diarrhea, hair loss, and disturbance in the functioning of the nervous system, lungs, heart, liver, and kidneys.Pol. J. Environ. Stud. Vol. 25, No. 5 (2016) AbstractThis study focused on determining thallium content in tobacco samples collected from a commercial cigarette brand commonly available in Poland (manufactured by Philip Morris). The samples were analyzed with the use of differential pulse anodic stripping voltammetry (DPASV) coupled with a flow injection analysis (FIA) system. The obtained results confirmed that thallium was present in the studied tobacco samples (average content at 0.0089 ±0.0012µg/g). These findings suggest that cigarette smokers in Poland may be exposed to the toxic effects of thallium-based compounds present in tobacco.

“…It is clear that a part of Tl was redistributed among Tl-free phases, mainly illite (proved by XRD, Table 1), specific soil silicates and oxides, or eventually SOM (Jacobson et al, 2005). Recent investigations dealing with Tl fractionation in contaminated soils document that a large portion of Tl is typically entrapped in soil silicates, i.e., after its mobilization from primary minerals such as sulfides (Karbowska et al, 2014). On the other hand, we suppose that this process affected the dynamics and/or biological uptake of Tl only minimally (see Plant uptake of Tl).…”
