“…In general, the fluoride levels in legume beans depends on several factors such as genetic variations (type of legumes), geographical locations, fluoride content and pH of soil and surrounding water bodies, climatic conditions and environmental factors [48]. The comparison of amount of fluoride in fava beans, green gram, white lupin, and three types of kidney beans are shown as a bar graph in Figure 2.…”

ABSTRACT. The most widely used legume beans food in Ethiopia are fava beans (Vicia faba), green gram (Vigna radiata), white lupin (Lupinus albus), and three types of kidney beans (Phaseolus vulgaris). These legume crops are grown in various regions of Ethiopia and can absorb significant amounts of fluoride from air, water, and soil. This study examined the fluoride content of legume beans collected from four different regions of Ethiopia by ion selective electrode potentiometry. Fluoride concentrations in this study were found to range from 1.9 to 22.8 mg/kg. Fava bean sample from Asella was found to contain higher fluoride (22.8 mg/kg) than in the fava beans from other sites and other beans from any site. Fluoride levels (13.0 mg/kg) in kidney bean from Migira was in the middle of the range while the fluoride levels (2.5 mg/kg) in the white lupin and green gram (1.9 mg/kg) were found in the lower end of the range. This study indicates that daily consumption of 100 g of fava and kidney beans may results in health problem while that of green gram and white lupin are safe for human health (will not exceed 3 mg/day set by Food and Nutrition Board of USA).

Water Purification: Adsorption over Metal‐Organic Frameworks

et al. 2016

View full text Add to dashboard Cite

Water pollution relating to human beings' health is a universal problem across community society. Highly efficient, economically feasible and easily achievable approaches are long-sought-after for water purification. Adsorption processes with porous materials (e.g. zeolites, activated carbon, silica gel, metal-organic frameworks (MOFs)) have drawn much attention in this field during past decades. In it, MOFs with numerous active sites, uniform porosity and tailorable structure diversity are arising to be one of the most promising adsorbents for water purification. During the adsorption processes, influence factors that determine or affect the usability and performances of MOFs are mainly focused on the stability of MOFs, their affinity for contaminants and the conducting conditions (pH, initial concentration of the contaminants). In this review, we will systematically present the performances of MOFs (mainly focused on MOF crystals, MOF nanomaterial or MOF composites will be beyond the scope of this review) for contaminants purification (inorganic and organic contaminants) in water and give a detailed discussion about the connection among their performances, conducting condition factors and potential interaction mechanisms (e.g. electrostatic interactions, coordination or p-p interaction). We hope this review will be beneficial to the design, regeneration and reuse of MOF adsorbents and promote the development of MOFs for water purification.

In the retrospective cohort study based on record linkage, the authors studied a cohort of persons born in 1900-1930 (n = 144,627), who had lived in the same rural location at least from 1967 to 1980. Estimates for fluoride concentrations (median, 0.1 mg/liter; maximum, 2.4 mg/liter) in well water in each member of the cohort were obtained by a weighted median smoothing method based on ground water measurements. Information on hip fractures was obtained from the Hospital Discharge Registry for 1981-1994. No association was observed between hip fractures and estimated fluoride concentration in the well water in either men or women when all age groups were analyzed together. However, the association was modified by age and sex so that among younger women, those aged 50-64 years, higher fluoride levels increased the risk of hip fractures. Among older men and women and younger men, no consistent association was seen. The adjusted rate ratio was 2.09 (95% confidence interval: 1.16, 3.76) for younger women who were the most exposed (>1.5 mg/liter) when compared with those who were the least exposed (< or =0.1 mg/liter). The results suggest that fluoride increases the risk of hip fractures only among women.
