The main idea of this study is to calculate 210Po activity in marine biota from Banda Aceh waters and calculate dose estimates for marine biota consumers. Polonium analysis was carried out for Kaka Tua fish, Layur fish, Talang-talang fish, Kawet fish, and sharks using alpha spectrometer. The highest 210Po activity was found in sharks at 16.90 Bq/kg and Kaka tua fish at 16.24 Bq/kg. This activity is slightly above the recommended value for seafood, which is 15 Bq / kg. Based on the calculation, the daily intake for adults is around 0.18-0.41 Bq, for children, it is 0.12-0.27 Bq, and infant are 0.06-0.14 Bq. The daily intake of adults and children exceeds the recommended annual intake limit. However, the annual intake of many countries in the Asian region, including Japan and China, also far exceeds the recommended value. The amount of marine fish consumed significantly influences this annual dose estimate. The estimated dosage of 210Po yearly for adult consumers is 32.3-71.42 µSv/year for children, it ranges from 46.65-103.16 µSv/year, and for infants, it ranges from 78.95-174.58 µSv/year. These values are similar to the UNSCEAR recommended values: around 70, 100, and 180 µSv/year for adults, children, and infants. Ide utama dari penelitian ini adalah untuk menghitung aktivitas 210Po pada biota laut dari perairan Banda Aceh dan menghitung estimasi dosis terhadap konsumen ikan laut. Analisis polonium dilakukan terhadap sampel ikan ikan kaka tua, ikan layur, ikan talang-talang, ikan kawet, dan ikan hiu menggunakan alfa spektrometer. Hasil penelitian menemukan aktivitas 210Po tertinggi pada ikan hiu yaitu 16,90 Bq/kg, dan ikan Kaka tua sebesar 16,24 Bq/kg. Aktivitas ini sedikit diatas nilai yang direkomendasikan untuk makanan laut, yaitu sebesar 15 Bq/kg. Berdasarkan perhitungan, asupan harian terhadap orang dewasa sekitar 0,18–0,41 Bq, untuk anak anak sebesar 0,12–0,27 Bq dan bayi sebesar 0,06-0,14 Bq. Asupan harian dewasa dan anak melebih batas tahunan asupan yang direkomendasikan, namun asupan tahunan dari banyak Negara di kawasan Asia termasuk Jepang dan China juga jauh melebih nilai yang direkomendasikan Jumlah konsumsi ikan laut sangat berpengaruh terhadap estimasi dosis tahunan ini. Penghitungan estimasi dosis 210Po tahunan terhadap konsumen dewasa adalah sebesar 32,3–71,42 µSv/tahun, untuk anak anak berkisar antara 46,65–103,16 µSv/tahun dan untuk bayi berkisar antara 78,95–174,58 µSv/tahun. Nilai ini mirip dengan nilai rekomendasi UNSCEAR, yaitu sekitar 70, 100 dan 180 µSv/tahun untuk dewasa, anak anak dan bayi.

The mercury content and the contamination characteristics of water, sediments, edible muscles of a non-piscivorous fish (Oreochromis nilotica Linnaeus 1758 [Cichlidae]) and yams (Dioscorea alata) from Namukombe stream in Busia gold district of Uganda were evaluated. Human health risk assessment from consumption of contaminated fish and yams as well as contact with contaminated sediments from the stream were performed. Forty-eight (48) samples of water (n = 12), sediments (n = 12), fish (n = 12) and yams (n = 12) were taken at intervals of 10 m from three gold recovery sites located at up, middle and down sluices of the stream and analyzed for total mercury (THg) using US EPA method 1631. Results (presented as means  ±  standard deviations) showed that water in the stream is polluted with mercury in the range of < detection limit to 1.21  ±  0.040 mg/L while sediments contain mean THg from < detection limit to 0.14  ±  0.040 ugg−1. Mean THg content of the edible muscles of O. nilotica ranged from < detection limit to 0.11 ± 0.014 ugg−1while D. alata contained from < detection limit to 0.30  ±  0.173 ugg−1mean THg. The estimated daily intake ranged from 0.0049 ugg−1day−1 to 0.0183 ugg−1day−1 and 0.0200 ugg−1day−1 to 0.0730 ugg−1day−1 for fish consumed by adults and children respectively. The corresponding health risk indices ranged from 0.0123 to 0.0458 and 0.0500 to 0.1830. Estimated daily intake was from 0.0042 ugg−1day−1 to 0.1279 ugg−1day−1 and 0.0130 ugg−1day−1 to 0.3940 ugg−1day−1 for D. alata consumed by adults and children respectively. The health risk indices recorded were from 0.011 to 0.320 and 0.033 to 0.985 for adults and children respectively. The mean THg content of the sediments, edible muscles of O. nilotica and D. alata were within acceptable WHO/US EPA limits. About 91.7% of the water samples had mean THg above US EPA maximum permissible limit for mercury in drinking water. Consumption of D. alata grown within 5 m radius up sluice of Namukombe stream may pose deleterious health risks as reflected by the health risk index of 0.985 being very close to one. From the pollution and risk assessments, mercury use should be delimited in Syanyonja artisanal gold mining areas. A solution to abolish mercury-based gold mining in the area needs to be sought as soon as possible to avert the accentuating health, economic and ecological disaster arising from the continuous discharge of mercury into the surrounding areas. Other mercury-free gold recovering methods such as use of borax, sluice boxes and direct panning should be encouraged. Waste management system for contaminated wastewater, used mercury bottles and tailings should be centralized.

Abstract Alue Naga waters are a coastal area in Banda Aceh city which is thought to have been exploited due to various human activities. The existence human settlements, tourist spots, fishponds, ports, and places for catching marine biota such as oysters, green mussels and fish are some instances to name a few.This research was conducted in July 2020 using simple random sampling method. Samples of green mussels were taken from a container for cultivation and from the bottom of the stream. Sample analysis was done using Atomic Absorption Spectrophotometer (AAS) at the laboratory of Office for Research and Standardization of Aceh Industries. The heavy metals that were analyzed are Lead (Pb) and Cadmium (Cd). The results showed that the content of Pb found in the cultivated green mussels was <0.0001 mg/Kg and Cd with <0.0002 mg/Kg. The metal content of green mussels found at the bottom of the stream was <0.0004 mg/Kg for cadmium and <0.0001 mg/Kg for lead. The intensity of heavy metal content in the seawater atcultivation locations also did not exceed the quality standard for the stream and aquatic biota with <0.0001 mg/L (Pb) and <0.0004 mg/L (Cd). Therefore, it is safe for human consumption.

This study was conducted to determine the heavy metals concentration in pepper fruits cultivated in Katsina state Nigeria. The objectives were mainly to detect the presence of heavy metals in the cultivated pepper fruits in the study area, compare the concentration of heavy metals in samples in relation to the permissible limits specified by WHO/FAO/USEPA Standards. Samples of the pepper fruits were collected in the year 2017 from the selected area. Analysis for the concentration of these heavy metals; Cr, Cd, Fe, Ni, Mn, Pb and Zn was conducted by the use of AAS (by Atomic Absorption Spectrophotometry) method. The health risks to the local inhabitants from the consumption of the samples were evaluated based on the Target Hazard Quotient. The possibility of cancer risks in the samples through intake of carcinogenic heavy metals was estimated using the Incremental Lifetime Cancer Risk. Results from this study has shown that with the exception of the mean values for the heavy metal Pb (1.200-1.333 mg/kg), the mean concentration range (mg/kg) values of Fe (0.901-0.967), Zn (0.899-0.911), Mn (0.250-0.287), Cd (0.053-0.0556) in the samples were generally lower than the USEPA, WHO/FAO maximum permissive limits. With the heavy metals Cr and Ni being below detection level (BDL) The results have indicated that the estimated daily intake (EDI) of the heavy metals were lower than the tolerable daily intake limit set by the USEPA in all the samples. Risk level of Target Hazard Quotient (THQ < 1) was observed for all the evaluated heavy metals for both adults and children. The THQ for the samples were in the decreasing order Mn>Zn>Pb>Fe>Cd, for all the pepper fruits respectively. The sequence of risk was the same for both adults and children although the children had higher THQ values in all cases. ILCR for Cd violated the threshold risk limit (>10−4) and ILCR for Pb reached the moderate risk limit (>10−3) in all the studied samples in adults, While in children ILCR for both Pb and Cd violated the risk. The sampling area trend of risk for developing cancer as a result of consuming the studied samples showed in decreasing order: Funtua senatorial zone > Daura senatorial zone> Katsina senatorial zone for both adult and children. The Cumulative cancer risk (∑ILCR) of all the studied pepper fruits reached the moderate risk limit (>10−3) in adults, while in children it is above the moderate risk limit (>10−2). Among all the studied samples, pepper sample from Funtua senatorial zone has the highest chances of cancer risks (ILCR 6.863273 × 10−3 in adults; ILCR 1.715815 × 10−2 in children) and pepper sample from Katsina senatorial zone has the lowest chances of cancer risk (ILCR 6.260100 × 10−3 in adults; ILCR 1.565025 × 10−2 in children). The study suggests that consumption of the studied pepper fruits in Katsina state is of public health concern as they may contribute to the population cancer burden.

AbstractHoney is a highly valued product due to its nutritional value, pro-health and healing properties. Pollutants from the environment penetrate into nectar, honeydew, pollen and next into bee products and can cause human exposure after ingestion. Mercury (Hg) is a toxic metal to living organisms. This is why it was important to determine the level of Hg in consumed honey.The aim of this manuscript is to analyse mercury concentration in honeys collected on the territory of Poland. A total of 108 samples of honey purchased in regional apiaries and hypermarkets were tested. The concentration of Hg was analysed in various types of honey (multifloral, honeydew, linden, goldenrod, acacia, buckwheat, rapeseed, sunflower, heather, dandelion, phacelia). The values of the Estimated Daily Intake (EDI), Estimated Weekly Intake (EWI) and % Provisional Tolerable Weekly Intake (% PTWI) were calculated. This allowed estimating the amount of Hg taken during consumption of the tested honeys.The concentration of Hg ranged from 0.01 to 1.71 µg/kg and was 0.43 µg/kg on average. A higher concentration of Hg, which was statistically significant, was recorded in honeydew honey, then in compound honeys. Honeys produced from one raw material had the lowest concentration of Hg. There were no significant differences in the concentration of Hg depending on the origin of honey. The calculations have shown that consumption of a portion (19 g) of the tested honey per week is safe for both adults and children according to the applicable standards.

This study was carried out to establish health impacts of some trace elements (Al, As, Ba, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in Asa-river, using Inductively Coupled Plasma-Mass Spectrometer technique for the chemical analysis. Laboratory results show that Al, Fe and Mn average concentrations are higher than prescribed limits unlike others. The Contamination Indexes reveal that the elements are heavily loaded in the water. The exposure dose in both adults and children ranges from 0.021 in As to 181 in Fe (in adults) and from 0.068 in As to 576 in Fe (in children). The average Hazard Quotient (HQ) values for adults and children are generally lower than one except Mn that has average value greater than one in both age groups. However, for children, individual HQ in Fe in some of the locations are >1. The Hazard Index (HI)for adults and children ranged from low to high. The average values of Chronic Daily Intake (CDI) are generally <1. However, in children, values for Fe in some locations are >1. The average Carcinogenic Risk (CR) of Cr and Pb computed for adults and children indicated that the values are greater than the risk limit of 10-6 and 10-4. This could result in potential health risk to the consumers. The sources of these trace elements are largely from various anthropogenic activities and slightly from weathering of rocks in the study area. It is recommended that adequate and well monitored precautions need to be taken to safeguard the health of the consumers especially the children with low immunity.

The present study was carried out to assess heavy metals Cadmium (Cd), Lead (Pb), copper (Cu), zinc (Zn), Chromium (Cr) and Nickel (Ni) levels in vegetables like Cauliflower (Brassica oleracea var. botrytis), Cabbage (Brassica oleracea), Carrot (Daucus carota), Brinjal (Solanum melongena), Spinach (Spinacia oleracea) and Radish (Raphanus sativus) irrigated with domestic wastewater. The vegetable samples were randomly collected from the farmlands irrigated with domestic wastewater around the Hisar district. Spinach, cabbage, brinjal and carrot accumulated higher Cd (1.30±0.31 mg kg-1), Pb (4.23±0.32 mg kg-1), Cu (1.42±0.25 mg kg-1), Zn (3.4±0.28 mg kg-1), Cr (1.16±0.11 mg kg-1) and Ni (2.45±0.86 mg kg-1) respectively. Transfer Factor (TF) of Cd, Pb, Cu, Zn, Cr and Ni are more in spinach (0.0306), cabbage (0.4448), spinach (0.2642), cauliflower (0.2494), carrot (0.0764) and spinach (0.7469) respectively. The health risk assessment has been calculated followed by Estimated Daily Intake Metal (EDIM) and Estimated Health Risk Index (EHRI). The present study highlights that both adults and children consuming vegetables grown in wastewater irrigated soils accumulate significant amount of these metals. However, the values of these metals were lesser than recommended maximum tolerable levelsproposed by the FAO/WHO (1999).

Tea (Camellia sinensis) is one of the most popular nonalcoholic beverages in the world. During tea infusion, both essential mineral elements and toxic metals are extracted into the beverage. In oriental countries, almost a liter of tea is consumed daily by an average adult. Thus, high toxic elements in traditional teas can be of concern. Aim of the study was to determine the essential element contents and toxic heavy metal concentrations in tea products available on the market in Turkey and comparing the contents of infusion for Turkish and Ceylon black and green tea types. The associated health risk to tea drinkers were estimated with reference to Tolerable Daily Intake (TDI) Values from US EPA for adults and children. Among the essential elements in all of the black teas purchased from the market, K was present at the highest concentration followed by Mg, Ca and Al. Pb and Mn contents of several tea samples were found over the Tolerable Daily Intake levels.

Abstract In this study, nitrate and nitrite contents were determined of a total (308) samples of 15 different types of vegetable such as leek, swiss chard, celery, spinach, garden cress, green onion, turnip, radish, aubergine, squash, tomato, pepper, cucumber, mint, and tarragon. They were taken from different fields located in Sulaymaniyah province: Sulaymaniyah city (Tanjarro and Kanaswra), Bazyan (Baynjan), Halabja (Said Sadiq), and Kalar (Grda Gozena). Using spectrophotometer measurements performed by UV/VIS double beam spectrophotometer at 538nm. The highest level of nitrate (529.55 mg/kg) for garden cress in Said Sadiq, (486.74 mg/kg) for Swiss chard in Kanaswra, and (477.65 mg/kg) for spinach in Bazyan. In addition, leek and celery contained high nitrate concentrations of about (416.65 and 447.60) mg/kg in Kanaswra and Bazyan, respectively. While the lowest nitrate concentration in fruiting vegetables like a tomato was 5.934 mg/kg in Bazyan, and aubergine in Grda Gozena was 5.617 mg/kg. Interestingly, the value of the Acceptable Daily Intake (ADI) and the Target Hazard Quotient (THQ) was lower than the standard limit, ADI for nitrate in this study was about (0.51, 2.18) mg/kg bw/day for adults and children, while the standard limit (3.70 mg/kg bw/day). Also, ADI for nitrite in this study was about (0.01, 0.05) mg/kg/bw for adults and children, while the standard limit was about 0 - 0.06 mg kg, as a result, the THQ ≤1. In summary, we can conclude that the amount of nitrates in raw vegetables was lower than the standard limit’s level and that this level does not cause health problems for consumers.
