Effect of smoking on cyanide, IL-2 and IFN-γ levels in saliva of smokers and nonsmokers

Introduction: Tobacco use is widely spread throughout the world. Smoking has several adverse effects on human health ranging from minor health conditions to death. Aim: This study aimed to investigate effect of smoking on level of saliva cyanide, interleukin-2 (IL-2) and interferon-gamma (IFN-γ) among smokers compared to nonsmokers in the city of Ilam, Iran. Material and methods: This study was carried out among two equal groups of smokers as cases and nonsmokers as controls (N = 76) which were matched in terms of their age range. Dental roll and direct saliva method were used to collect samples. The saliva sample was stored at –18°C. The level of salivary cyanide was measured using the spectrophotometric method. IL-2 and IFN-γ were measured by ELISA. Results and discussion: We found level of cyanide in the saliva of smokers was higher than that in nonsmokers. In addition, level of cyanide in the smokers’ saliva increased (164.21 ± 18.54 µg/mL) significantly compared to nonsmokers (42.63 ± 24.01 µg/mL). A significant increase was found in the level of IFN-γ and IL-2 among smokers compared to nonsmokers. However, there was a significant decrease in the level of IFN-γ and IL-2 with increased intensity of smoking. Conclusions: Heavy smoking was associated with an increased level of salivary cyanide and a decreased level of sera IFN-γ. Recognizing immunosuppression mechanisms produced by cigarette-smoking is a platform for identifying the best therapeutic and management approaches in smoke-induced diseases. © 2018 Warmia and Mazury Medical Chamber.

Improvement the Chemical Properties of Cassava Through Microbial Fermentation Using Rhizopus Oligosporus

Indonesia is the world’s largest importer of wheat. Because of high wheat imported, Indonesia’s researchers has seek an alternative to wheat-based local materials that having equivalent physicochemical properties. Potential alternative replacement of wheat flour is cassava. Cassava can be modified its rheology and physicochemical properties in order to be wheat equivalents. Cyanide contained in the cassava flour cannot be removed immediately by physical treatment. Several efforts have been made, such as soaking with saline solution, the addition of citric acid, and heating, showed a reduction in levels of cyanide in the flour. In this study, reduced levels of cyanide bound by converting it into protein using of Rhizopus oligosporus. While cyanide dissolved with the help of soaking with saline solution and buffer solution. In this case, use a buffer solution such as sodium sulphites which serves to change the form of cyanide dissolved into a form that is less toxic. In addition, a buffer solution pH also controls a range of 6, because in this range of cyanide bound to be easier to dissolve. With the combination treatment is expected to be a reduction in the levels of cyanide and exhibited significantly increased levels of protein in cassava flour. Flour has a protein content of best nutritional protein at 3.68 % dry basis. Cyanide reduction was highest in samples with high levels of Rhizopus oligosporus grated 1.5% (w/w) as 72 hours, with a lag of 0.09 (mg/kg) cyanide. Flour with the best nutritional quality is obtained from fermentation with conditions: grated, 12 hours of fermentation as well as using Rhizopus oligosporus 3.5% (w/w).

Optimization of the fermentation time and bacteria cell concentration in the starter culture for cyanide acid removal from wild cassava (Manihot glaziovii)

Cassava is one of the most widespread starchy tuberous roots in Indonesia, being one of the typical plants used in the starch market. However, due to the high cyanide content (338.41 ppm), these roots become a poison if they are unsuitably processed. Therefore, a detoxification process is needed to reduce the cyanide level to the safe level for human consumption (10 ppm). This study was focused on (i) the investigation of the detoxification potential of fermentation with Lactobacillus plantarum (L. plantarum) on the cyanide level of wild cassava tubers (Manihot glaziovii) and (ii) the optimization of the fermentation time and bacteria cell number in the starter culture. The fermentation was performed for different periods of time (12, 24 and 36 h) and various initial bacteria cell number (7x1010, 7x1011, 1.05x1012, and 3.5x1012 L. plantarum cells). The results showed a significant decrease of the cyanide level, 97 % of cyanide degradation being noticed after 36 h of fermentation for an initial bacterial cell number of 3.5x1012 cells. Hence, the strong point of the study consists of a noteworthy reduction of the cyanide content in wild cassava in short periods, whereas the protein content was increased (from 1.5% to 3.5%) in Modified Cassava Flour (MOCAF).

Organic pollutant degradation of tapioca flour industrial waste with photo-fenton reaction

Cassava (Manihot utilissima) is the main raw material of tapioca flour industry. The tapioca industry waste water still contains high enough BOD, COD, and cyanide, above the quality standard of industrial waste water. Photo-Fenton is one of the most effective alternative methods of degrading organic pollutants. This study aims to determine the effect of Photo-Fenton method on the degradation of organic pollutants such as COD and cyanide. For operating conditions of this study use the addition of concentrations of H2O2 and FeSO4.7H2O and different UV light intensity. The analysis of COD concentration using SNI method is spectrophotometric. From the research result, it is found that the concentration of COD and cyanide in tapioca waste can be reduced by using Photo-Fenton method. With initial COD content of 6000 mg/L and cyanide level of 0.67 mg/L. And in the operating conditions of the addition of 5 ml/l of H2O2, Fe2+ 1.25 mg/l, and light intensity of 200 lm, the highest COD and cyanide levels were found to be 900 mg/l for COD and 0.08 mg/l for cyanide. Final levels of COD up to 900 mg/l and cyanide concentrations up to 0.08 mg/l.

Homocysteine Lowering with B Vitamins for Stroke Prevention—A History

Early trials of B vitamin therapy to lower plasma total homocysteine (tHcy) reported no reduction of stroke with high doses of folate/B6 and cyanocobalamin 400–1,000 μg daily. In patients with diabetic nephropathy, folate/B6 and cyanocobalamin 1,000 μg daily accelerated the decline of renal function and doubled cardiovascular events. Patients with renal failure have high cyanide levels. The French SUpplementation with FOlate, vitamin B6 and B12 and/or OMega-3 fatty acids (Su.Fol.OM3) trial—with the best renal function of the early trials and the lowest dose of cyanocobalamin (20 μg daily)—reported a 43% reduction of stroke. Then the China Stroke Primary Prevention Trial (CSPPT) reported that folic acid alone reduced stroke and was beneficial even in patients with impaired renal function. Patient-level data from the Vitamin Intervention to Prevent Stroke (VISP) and VITAmins TO Prevent Stroke (VITATOPS) trials and meta-analyses stratified by renal function and dose of cyanocobalamin confirmed that harm from cyanocobalamin among participants with renal impairment obscured the benefit of B vitamins in the early trials. It does seem that B vitamins reduce the risk of stroke. In the era of folate fortification, B12 is the main nutritional determinant of tHcy, and metabolic B12 deficiency is very common and usually missed. Therefore, folate alone is not the optimal way to lower tHcy: the use of folate (and possibly B6) with methylcobalamin or oxocobalamin should be considered.

RECOVERY OF CYANIDE FROM EFFLUENTS USING CARBON DIOXIDE

Cyanidation effluents are treated in order to reduce the cyanide level down to regularity limits. Cyanide recovery is the most desired route for treatment of effluents of high cyanide consuming ores, in particular, due to economic and environmental incentives. In this study, carbon dioxide (CO2) was utilised as an alternative for acidification of cyanide solutions prior to absorption/recovery of hydrogen cyanide (HCN(g)) in alkaline solutions. Kinetic tests have indicated that reaction time is an important parameter for the recovery of cyanide, which reached 89.1% over a period of 90 min. Effects of concentration of cyanide (0.5-1.5 g/L NaCN), flow rate of carbon dioxide (0.38-1.15 L/min. CO2) and time (30-90 min.) on the recovery of cyanide (%) were investigated in detail by a two-level full factorial design (23). The statistical evaluation of the data showed that flow rate of carbon dioxide and time were statistically significant parameters. Efficiency of the process was not affected by the concentration of cyanide. The results demonstrated that high recoveries of cyanide up to 93.1% could be achieved under suitable conditions. Introduction of air (1.15 L/min.) as a carbon dioxide source was found to be inefficient and require longer reaction periods for high recoveries i.e. no recovery at 90 min. vs. 95.4% at 24 h. A separate test performed using a real pregnant leaching solution (PLS) yielded a cyanide recovery of 49.7%. These finding demonstrated that using carbon dioxide can be used for acidification of cyanide solutions for cyanide recovery.

A composable module-type cyanide microfluidic sensor based on polydimethylsiloxane membrane pervaporative sampling with sodium bicarbonate internal-pressure regulation and dual fluorescence/potentiometric monitoring

This paper demonstrates a reliable and safe microfluidic sensor on the monitoring of weak-acid dissociable cyanide (WAD-CN−) from environmental waters. The sensor chip consists of three parts: a pervaporative membrane sampling module, a fluorescence labelling/detection module and a cyanide ion selective-electrode (CN−-ISE) potential detection module. Cyanide pervaporation was achieved by in situ sample acidification to produce hydrogen cyanide (HCN) through a gas-diffusing polydimethylsiloxane (PDMS, 4–5 μm thickness) membrane. HCN was recovered using a lye solution and subsequently split into two streams for the dual fluorescence/potentiometric monitoring. Dual fluorescence and CN−-ISE potential monitoring were performed by applying two indispensable treatment to the split streams with naphthalene-2,3-dicarboxaldehyde (NDA)-glycine (Gly) and total-ionic-strength-adjustment buffer solution (TISAB), respectively. The parameters in the pervaporation process and both detections were optimized. To increase the sensitivity at low concentrations, a sodium bicarbonate solution was introduced into the sample stream as a chemical pressure regulator, which maintained a constant pressure in the channel by continuously producing CO2. To prevent the loss of produced gas, the channels, except for the membrane, were coated by a polyvinylsilazane (PVSZ) polymer solution and cured. Under an HCl donor stream (0.5 mol L−1; 15 μL min−1) and a sodium hydroxide acceptor stream (0.1 mol L−1; 20 μm/min), 65.7% of transmission rate (RSD = 0.86%; n = 3 for 0.1 mg L−1 CN−) was achieved. The pervaporative sampling method effectively minimized the interferences (except organic thiols) from the environmental matrices during the detection of cyanide in both detection modules. The validity and quality of the assay were assessed in terms of the linearity 5–500 μg L−1 (R2 = 0.9992) and limit of detection (cL) 0.015 μg L−1 with the fluorescence method and those are 2.6–1000 μg L−1 (R2 = 0.998), and 1.1 μg L−1 with the CN−-ISE potentiometric detection. The cyanide levels in waste waters were determined using the standard addition method and verified using the EPA method OIA-1677. Furthermore, a microchip electrophoresis (MCE) analysis was performed to investigate the systemic errors from the mercapto-interferences of the samples. The developed microfluidic sensor was applied to monitor WAD-CN− in waste waters. The sensor is a flexible, extensible, and environmentally friendly alternative for WAD-CN− monitoring.

Effects of surface gold mining on surface and groundwater bodies in Bibiani, Ghana

A study of the water sources from Bibiani and its environs was conducted between November, 2009 and April, 2010 to determine whether contamination (of water sources) from (these parameters) physical, chemical and trace metal in Bibiani is as a result of mining or geochemicaland biochemical processes within the environment. This was done by collecting water samples from two streams, two rivers, three boreholes (BHs) and three hand dug wells (HDWs). These were analysed in the laboratory. Levels of Arsenic (As), Iron (Fe), Manganese (Mn), pH, TotalDissolved Solids (TDS), Electrical Conductivity (EC), Temperature, Alkalinity, Hardness, Phosphate (P) and Cyanide (CN) in water sources were determined. Mining related contaminants detected in water samples were As, CN, Mn and Fe. It was observed that surface water pH values were generally higher than that of groundwater samples. As concentrations in surface water samples were higher compared to that of groundwater samples. Also, CN concentration in ground water samples was higher than that of surface water. Ground water contained higher concentration of Mn than surface water; the opposite can be said of Fe concentration in surfacewater which was higher than that of ground water. The study also observed that pH, TDS, EC, total alkalinity, total hardness , Arsenic and total cyanide levels in the HDW and BH samples showed 100% compliance with the WHO and EPA limits while Mn and Fe levels indicated traces of non – compliance. Compared to WHO / EPA guidelines, few water sources had one or moretrace metal (Fe, As and Mn) levels outside acceptable limits for drinking. However, most of the levels were safe for human consumption.Keywords: Surface, gold mining, quality, degradation, Bibiani

Proximate, Anti-Nutrient and Vitamin Composition of Full-Fat and Defatted Seed Flour of Telfairia occidentalis

Studies were conducted to determine the proximate and anti-nutrient composition of full-fat and defatted seed flour of Telfairia occidentalis (fluted pumpkin) using standard procedures. The defatted seed flour (DSF) indicated higher protein content (46.55%) while the full-fat seed flour (FSF) presented a value of 10.20%. The lipid (35.78%), carbohydrate (42.27%), and caloric values (531.90 Kcal/100 g) obtained for FSF were respectively higher than values of similar determinations for DSF. The anti-nutritional analyses of the FSF showed slightly higher oxalate content (44.00 mg/100 g) while cyanide, phytate and tannin levels were higher in DSF. The vitamin A composition of FSF (9.18 mg/100 g) was higher than that of DSF (0.84 mg/100 g) while DSF indicated higher vitamin C (74.44 mg/100g) content. These results revealed that the seed flour of Telfairia occidentalis contains an appreciable amount of nutrients and vitamins. The levels of toxicants in both FSF and DSF samples were low and below toxic levels. The seed flour of Telfairia occidentalis can be exploited as a cheap and valuable source of vegetable protein in fortified food products formulation.

Evaluation of Cyanide Levels in Two Cassava Varieties (<i>Mariwa</i> and <i>Nyakatanegi</i>) Grown in Bar-agulu, Siaya County, Kenya

Mannihot esculenta Crantz (Cassava) is the second highest producer of carbohydrates after sugarcane. However, some varieties have high levels of cyanogenic glycosides and therefore are potentially toxic for human consumption. Nyakatanegi is one of the local varieties cultivated in Bar-agulu village in Siaya County (Kenya) and has been severally in the recent past reported to cause fatal cyanide toxicity. The other variety which is rarely associated with cassava poisoning is Mariwa. The objective of the current study was to determine cyanide levels in the two cassava varieties (Mariwa and Nyakatanegi) which are locally cultivated in Siaya County. The study was based on three laboratory assays: the picrate paper, picrate in solution and titration. Whole root cassava tubers were collected from a farmer in Bar-agulu village, Siaya County, packaged separately and transported to Mount Kenya University Pharmaceutical Chemistry Laboratory for analysis. Voucher specimens were authenticated in the cassava laboratories at Jomo Kenyatta University of Agriculture and Technology. It was observed that all the cortex samples of Nyakatanegi variety had the highest concentrations of cyanide giving 400 ppm for the picrate paper assay, 14.10 mg/Kg for the picrate in solution and 63 mg/Kg for the titration assays. On the other hand, the cortex samples of Mariwa reported cyanide concentrations of 30 ppm, 11.20 mg/Kg and 27.20 mg/Kg for the picrate paper, picrate in solution and titration assays respectively. The results showed higher amounts of cyanide in the tested cassava varieties than the WHO recommended levels (10 mg/Kg) especially the Nyakatanegi variety. Based on these results, sensitization campaigns are necessary to minimize cases of cyanide poisoning following cassava consumption.

Human health risk assessment of cyanide levels in water and tuber crops from Kenyasi, a mining community in the Brong Ahafo Region of Ghana

BackgroundCyanide is among the most harmful substances on Earth and it is harmful to humans and most aquatic life even at low concentrations. Free, total cyanide levels and other physicochemical parameters were determined in fish, cassava, cocoyam, dam and borehole water samples collected from Kenyasi, Ghana. A total of sixteen (16) water samples, five (5) fish samples, twenty (20) cassava and cocoyam tubers were collected from the study area. Free and total cyanide levels were determined using Skalar San++ Automated Wet Chemistry Analyser with Continuous Flow method.ResultsThe mean free cyanide levels in fish, cassava, cocoyam, dam and borehole water samples were 63.09, 33.26, 15.44, 0.16 and 0.18 mg/L, respectively, while the mean total cyanide levels were 93.60, 43.47, 29.62, 21.70 and 25.09 mg/L in fish, cassava, cocoyam, dam and borehole water samples, respectively. The mean pH value in fish, cassava, cocoyam, dam and borehole water samples were 6.90, 6.46, 6.82, 5.84 and 6.59, respectively. The mean conductivity was 153.64, 156.83, 76.03, 207.39 and 205.99 in fish, cassava, cocoyam, dam and borehole water samples, respectively. Results of two-way Analysis of Variance test showed that the variation in free cyanide levels was significant (p < 0.05) in the fish, cassava, cocoyam, dam and borehole water samples. Moreover, the hazard index results via ingestion and dermal contact with children are >1, including fish ingestion by an adult. This signifies adverse non-carcinogenic risk. The persistent intake of cassava and cocoyam can probably induce adverse health effects.ConclusionsFrom the results, it can be concluded that fish, cassava and water samples at Dam 4, Dam 7 and BH1 were not safe for consumption since they recorded values higher than the set limits. Therefore, people are advised not to feed on the cassava product, fish and consume water samples located close to Dam 4, Dam 7 and BH1.

Effectiveness of Traditional Processing Techniques in Reducing Cyanide Levels in Selected Cassava Varieties in Zombo District, Uganda

The root tubers of cassava (Manihot esculenta Crantz) contain varying amounts of cyanogenic glucosides which liberate toxic hydrogen cyanide with the resultant effect of poisoning especially the highly cyanogenic cultivars. These include some of the local and improved cassava varieties grown in Zombo district, Uganda among others. Therefore, this study explored the effectiveness of some traditional processing techniques used singly and in combination to reduce cyanide levels in highly toxic root tubers of selected local (Nyar-anderiano, Nyar-papoga, Nyar-udota, Nyar-pamitu, Bisimwenge, Nyar-matia) and improved (NASE 3, NASE 9, NASE 14, NASE 19, TME 14 and TME 204) cassava varieties grown in Zombo District, Uganda. The processed and the fresh cassava tubers were analysed for Hydrogen cyanide (HCN) by the standard titration method. The results indicated that heap fermentation followed by sun-drying reduced the cyanide levels in all the selected improved varieties to WHO safe levels for consumption (below 10mg/kg) in the dried chips. Mixed processing methods combining soaking, fermentation and sun-drying reduced the cyanide concentrations in the local varieties (Nyar-udota, Nyar-anderiano) and improved variety (NASE 19) to World Health Organisation (WHO) safe levels. None of the processing techniques used singly reduced the HCN levels in the root tubers of the selected cassava varieties to safe levels. Hence mixed strategies combining several traditional cassava processing techniques should be adopted to detoxify the selected cassava varieties of cyanogens. The local cassava varieties (Bisimwenge, Nya-matia, Nya-pamitu, Nya-papoga) would require modifications of the combined traditional processing techniques or other more complex processes to detoxify them of HCN before human consumption.

Effect of different processing methods on nutritional composition of &lt;i&gt;Leucaena leucocephala&lt;/i&gt; (Lam De Wit) leaves as inclusion in Fish Feed

The potentials of Leucaena leucocephala leaf-meal as a supplementary protein in fish feed as evaluated. Leucaena leaves were subjected to two processing methods (sundrying and boiling) to determine the effect of these treatments on proximate composition and anti-nutritional factors. Five samples of Leucaena leaves were analyzed, sundried for 24 hours (SD 1 ), sundried for 48 hours (SD 2 ), sundried for 72 hours (SD 3 ), soaked in boiled water for five minutes at 100°C (SB 5 ) and unprocessed (SU). The tests were carried out in triplicate for each treatment. Data obtained were subjected to one way analysis of variance. Sun-drying (SD 1 , SD 2 , SD 3 ) led to a significant (P≤0.05) increase in crude protein, ash, phosphorus, potassium, magnesium and sodium when compared with the soaked in boiled water (100°C) for 5 minutes (SB 5 ) treatment. The sample soaked in boiled water for 5 minutes (SB 5 ) gave 73, 90, 81, 97 and 36 % reduction in the levels of phytate, cyanide, tannin, saponin and mimosine respectively, which was better than the sundried treatments. Key Words : Leucaena leucocephala , anti-nutritional factors, nutritional composition, supplementary protein, mimosine, fish feed.

Does diathermy smoke contaminate processed salvaged blood in cardiac surgery?

A cell salvage device is used in cardiac surgery with the aim of reducing allogeneic blood transfusion. Suction of blood from the operating field used for the device is often accompanied by diathermy smoke. There is limited published research to know if this blood is then contaminated with clinically significant levels of harmful chemicals from this smoke. Postoperative cardiac surgery patients are already physiologically vulnerable, making the optimization of salvaged blood worth considering. Ten patients who had cardiac surgery using a cell salvage device from a single institution had samples taken from the processed blood just prior to transfusion. Samples were tested for carbon monoxide (CO), cyanide and benzene. Results were compared to preoperative co-oximetry results and normal adult laboratory reference ranges. Demographic data about the patients was collected, including the type of operation, gender, age, body mass index, smoking status and amount of salvaged blood collected and processed. Primary surgery was coronary artery bypass grafting (CABG) in three patients, mitral valve repair or replacement in three patients and one each of aortic valve replacement (AVR)/CABG, AVR/plication of the aorta, CABG/external wrapping of the aorta and valve-sparing root replacement. None were smokers. Neither the blood CO level prior to surgery nor in the processed salvaged blood was above the normal limit of 2% for non-smokers. There was no processed blood benzene found. Cyanide levels in the processed blood ranged from 1.8 to 44.1 μmol/l (where <8 μmol/l is considered within the normal adult laboratory limit). Despite the obvious limitations of the current study, it shows that cyanide levels can be found many times the normal level in processed salvaged blood. Whilst the total dose of cyanide is small, the potential impact may be clinically significant due to cyanide's effect on mitochondrial metabolism in the heart and brain.

Oral and intramuscular application of cyanogenic glycoside amygdalin did not induce changes in haematological profile of male rabbits

Amygdalin is a cyanogenic glycoside initially obtained from the seeds of bitter almonds. It is composed of one molecule of benzaldehyde, two molecules of glucose and one molecule of hydrocyanic acid. Various ways of amygdalin application play a different role in recipient organism. Intravenous infusion of amygdalin produced neither cyanidemia nor signs of toxicity, but oral administration resulted in significant blood cyanide levels. The present in vivo study was designed to reveal whether amygdalin is able to cause changes in the haematological profile and thus alter the physiological functions, using rabbits as a biological model. Adult male rabbits (n = 20) were randomly divided into five groups: the control group without any amygdalin administration, two experimental groups received a daily intramuscular injection of amygdalin at a dose 0.6 and 3.0 mg.kg-1 b.w. and other two groups were fed by crushed apricot seeds at dose 60 and 300 mg. kg-1 b.w., mixed with commercial feed over the period of 14 days. After two weeks, haematological parameters in whole blood were analysed (WBC - total white blood cell count, LYM - lymphocytes count, MID - medium size cell count, GRA - granulocytes count, RBC - red blood cell count, HGB - haemoglobin, HCT - haematocrit, MCV - mean corpuscular volume, MCH - mean corpuscular hemoglobin, MCHC - mean corpuscular hemoglobin concentration, RDWc - red cell distribution width, PLT - platelet count, PCT - platelet percentage, MPV - mean platelet volume, PDWc - platelet distribution width) using haematology analyser Abacus junior VET. Our findings indicate that intramuscular and oral application of amygdalin for two weeks did not significantly affect the haematology parameters in experimental animals. In this study, no obvious beneficial or negative effects of amygdalin administration on the blood of male rabbits were observed.

Nutritional Composition and Acute Toxicity Potentials of Archontophoenix tukeri and Adonidia merrilli Kernels

Archontophoenix tukeri and Adonidia merrilli are exotic species widely grown in Nigeria as ornamental palms. In this study, the kernels of A. tukeri and A. merrilli were subjected to amino acids, fatty acids, proximate, anti-nutrients and mineral element analyses, in addition to acute toxicity evaluation. Glutamic acid (11.30 and 5.33 g/100 g) and leucine (5.9 and 4.2 g/100 g) were the most abundant essential and non-essential amino acids; the fatty acids profile revealed three major fatty acids: palmitic acid (20.14 and 11.27%), oleic acid (61.83 and 25.78%) and linoleic acid (13.05 and 55.26%); low linolenic acid levels were also observed (˂1%) with 75.87 and 81.98% total unsaturated fatty acids in A. tukeri and A. merrilli respectively. Carbohydrate (85.73% and 90.15%) and oxalate contents (1927.2 and 2072.4 mg/100 g) were relatively high, while low levels of cyanide (12.05 and 65.45 mg/100 g), phytates (6.32 and 2.53 mg/100 g) and tannins (35.36 and 20.16 mg/100 g) were observed. A. tukeri indicated higher Ca, Cu, Fe, Zn, Mg, Mn and Na contents. The anti-nutrient-mineral ratios were computed and compared with critical values. Acute toxicity of A. tukeri and A. merrilli was 866.03 mg/Kg. These palms contain vital nutritional components, and with proper processing could serve as potential products for both human and animal nutrition.
