“…The mean levels of heavy metals were 0.009 mg/kg for Arsenic, Chromium, and Lead and 0.01 mg/kg for Cadmium while 578.2 mg/kg was obtained for Iron. The food and agricultural organization/world health organization, FAO/WHO permissible values of As, Cd, Pb, and Fe in the plant are 0.05, 0.2, 0.1, and 300 mg/kg, respectively (Kaba et al, 2020;Kusse, Zewde, & Yoseph, 2019). This indicates that the amount of iron in studied ginger samples exceeds the maximum permissible le vel set by the aforementioned organization.…”

“…The southwest (Kaffa, Ilu Aba Bora and Bunno Bedelle, Gamo Gofa, Wollaga), Southern (Sidama), and northern part (Gojjam, Gondar) are the major ginger-producing areas in Ethiopia (Kaba, Doda, & Kanido, 2020;Wagesho & Chandravanshi, 2015). It is currently being used as an important cash crop and also in the preparation of a local 'wots'-a routinely used stew with 'Injera' as the main food.…”

Ginger is a medicinal plant widely used as a spice and botanically categorized in the Zingiberaceae family, Zingiber genus, and officinale species. Natural and anthropogenic sources can discharge heavy metals into the environment from which they enter the human body through food, water, air, and skin contact and cause detrimental health effects. In this study, ginger samples were randomly collected from five kebeles in Ilubabor and Bunno Bedelle zones, Southwest Ethiopia, from which a composite sample was made for analysis. Microwave-assisted digestion was carried out using concentrated nitric acid in the presence of hydrogen peroxide followed by atomic absorption spectrometer detection using different Association of Analytical Chemists, AOAC methods. Proximate analysis was performed with different standard operating procedures. The mean levels of heavy metals were 0.009 mg/kg for Arsenic, Chromium, and Lead and 0.01 mg/kg for cadmium while 578.2 mg/kg was obtained for iron. Proximate composition analysis shows 82.89%, 2.00%, 0.07%%, 1.63%, 3.42%, 9.99%, and 48.59 kcal for moisture, crude protein, crude fat, ash, crude fiber, carbohydrate, and energy, respectively. The validated method had acceptable linearity (R2 = 0.9978 - 0.9993), the limit of detection (8.18x10-5 - 0.0075), the limit of quantification (2.7x10-4 - 0.025), recovery (75 - 106.87%) and precision (4.77 - 13.97 %). The hazard index (HI) of the metals was less than one showing insignificant non-carcinogenic risk from exposure to a single or multiple possibly toxic elements from the studied ginger samples.

“…Recently several studies have been conducted to determine heavy metals in several spices cultivated in Ethiopia. These studies include levels of selected metals in the sweet basil (Ocimum basilicum L.), Black Cumen (Nigella sativa) and Tenadam (Ruta chalepensis) species [19], levels of essential and non-essential metals in ginger (Zingibero cinale) [20][21][22][23], in the korarima seeds [3], in the bulb and leaves of garlic (Allium sativum L.) [14], health risk assessment of heavy metals in spice samples (ajwain, black cumin, coriander and fenugreek) [16] and levels of selected metals in the leaves of RUTA CHALEPENSIS L. (RUE) [24]. These studies clearly show the importance of strict and periodic monitoring of heavy metals in spices sold in commercial markets to protect human health and the food industry.…”

The objective of this study was to determine the heavy metal contents of some common spices commercially available in the North Shewa Zone, Oromia region, Ethiopia. Korarima seeds (Aframomumcorrorima), ginger rhizomes (Zingibero cinale), red pepper fruit (Capsicum annum), and turmeric rhizomes(Curcuma longa) samples were randomly collected from the Fiche open market. These spices samples were digested using a mixture of 3 mL of HNO 3 (69-72%) and 1 mL of HClO 4 (70%). The content of heavy metals (Fe, Zn, Cu, Cr, Mn, Ni, Cd, and Pb) in spices was determined by inductively coupled plasma-optical emission spectrometry (ICP-OES). The results obtained showed that the concentrations of heavy metals in the korarima, red pepper, ginger and turmeric samples in mg kg − 1 dry weight were in the range of Fe (38.7-98.9), Mn (10.5-257.3), Zn (7.3-29.2), Cu (1.7-6.5), Cr (5.4-9.7), Cd (1.5-2.9), Pb (14.5-28.4) and Ni (3.9-6.7. The heavy metal contents in korarima, red pepper, ginger, and turmeric samples were compared with the maximum values given by the World Health Organisation (WHO) in the vegetables. Accordingly, Fe, Zn, Cu, Cr, Mn, Ni, and Cd values in the spice samples were found to be lower than the maximum limit of WHO, while the levels of Pb in four spices samples were higher than WHO permissible limit. Moreover, Mn (only in ginger) exceeded the maximum allowable concentrations among spices. This study shows that consumption of korarima, red pepper, ginger, and turmeric may have a serious health threat to consumers due to the high content of lead and manganese in spices. Therefore, it is suggested that further study be conducted on spices samples based on the origin of cultivation to determine which hotspot is responsible for high levels of contamination of lead and manganese to protect consumers.
