“…The HQ value of <1 for an element confirms no adverse effect on human health arising from its intake ( USEPA, 2007 ). Several studies have been conducted to evaluate the impact of toxic metals from tea on human health ( Barman et al, 2020 , Karak et al, 2017 , Li et al, 2015 , Nkansah et al, 2016 ). Li et al (2015) and Shen & Chen (2008) observed that HI values of trace elements from consumption of 1250 mL tea infusion per day prepared from 8 g tea were much lower than the safety limit.…”

“…The consumption of infusions as common as tea (Camellia Sinenses L) can increase chromium concentrations in biological liquids. Barman et al (2019) have conducted extensive research on the detection of arsenic and chromium in this type of plant, finding that the concentration of chromium in some tested black tea samples varied from 0.62 to 36.76 μg/g, with a mean and median of 10.33 μg g−1 and 8.33 μg g−1, respectively (Barman et al, 2019).…”

Background: Hexavalent chromium compounds are sensitizers of the skin and lung. Chronic exposure to hexavalent chromium compounds is associated with respiratory effects and ulceration and perforation of the nasal septum. Such compounds are also considered carcinogens of the lung and nasal and paranasal sinus. Objectives: To demonstrate the importance of studying occupational and non-occupational exposure when assessing the concentration of substances in the urine. Case study: A study was conducted of environmental chromium concentrations in the workplace. In addition, an occupational medical examination was performed, recording activities inside and outside the workplace, eating habits, blood lead and urine chromium at the beginning and end of the workday. Results: One worker exposed to lead chromate presented high chromium concentrations in urine (up to 62 µg/l before the working day and 52 µg/l at the end of the working day). Environmental chromium concentrations in the workplace were below 0.25 µg/m3. In view of the results, a full study was conducted of the patient’s habits outside work. He reported having bought a kilo of a medicinal herb infusion at a street market three weeks previously. The concentration of total chromium in the prepared infusion was 12000 µg/l. The patient stopped consuming the medicinal herb. Subsequently, the urine chromium analysis was below 0.5 µg/l. Discussion and Conclusions: This case is interesting because it demonstrates that the consumption of medicinal herbs can interfere with biological monitoring of workers exposed to hexavalent chromium compounds. This may give rise to confusion and can also create legal problems for companies and workers. It is important to provide advice to workers and to investigate their habits outside work, especially when there is a discrepancy between environmental and biological values. In this case, the increase in urinary chromium is due to the consumption of medicinal herbs.

“…Arsenic content in tea samples presented here is below the value of 1 mg/kg, stipulated by the national legislation [10]. Ražić and Kuntić [5] have examined arsenic content in samples of mint, chamomile and rose hip. Arsenic content in mint samples (original package) of 0.086 mg/kg and of 0.155 mg/kg (bulk) is significantly higher than those in our study 0.013 ± 0.001 mg/kg.…”

Introduction. Arsenic exists in various forms in nature and living organisms.Toxic elements, including arsenic, which are present in some plants,can severely damage haemopoietic, immune, nervous and reproductivesystems. For this reason, a content of heavy metals is one of the criteria forthe assessment of the safe use of plant material in the production of traditionalmedicines and herbal infusions. This instigates the need for constantand organized safety control of plants that are used as raw materialsin pharmaceutical industry.The aim of this study is to determine the arsenic content in selected teaswhich are available on the market of the Republic of Srpska.Methods. The 10 g samples of 13 herbal and 3 fruit teas were mineralizedby dry ashing and arsenic contents were determined by the atomicabsorption spectrophotometer Agilent Technologies Series 200 with anair-acetylene burner and D2 background correction.Results. Mean arsenic concentrations in the herbal tea samples rangedfrom 0.009 to 0.145 mg/kg. The lowest arsenic concentration in a singlesample of 0.007 mg/kg was found in Chamomile tea and Uva ursi collectedas a wild plant at elevation above 1200 m. The highest arsenic concentrationwas found in the sample of Sambucus nigra tea (0.145 mg/kg). Infruit teas, the arsenic concentration ranged from 0.014 mg/kg (Cranberry)to 0.027 mg/kg (Fruit mix).Conclusion. Arsenic content in all analyzed tea samples is below the valuestipulated by the national legislation.
