Background Epithermal instrumental neutron activation analysis (EINAA) technique is used for the determination and estimation of the concentration levels of micronutrients such as Sodium (Na), Magnesium (Mg), Potassium (K), Calcium (Ca), Manganese (Mn), Copper (Cu) and Iodine (I) in breastmilk. Aim To examine the concentration of seven micro elements in the breastmilk of lactating mother who were exclusively breastfeeding. Methods This study employed quantitative experimental research where 27 lactating mothers voluntarily participated in the study from two health facilities in the Cape Coast Metropolitan area. Data was collected over a period of four weeks. A three millimetre (3mm) thick of flexible boron was used to cut off thermal neutrons in order to assess epithermal neutrons. This was done to create an activation energy which examines the amount of the 7 micro nutrients in the breastmilk. The standard reference materials used were the International Atomic Energy Agency (IAEA)-336; IAEA-407, IAEA-350 and National Institute of Standard and Technology (NIST) USA SRM 1577b. The Relative standardization method was used in the quantification of the elements. Results The study achieved about 94.7% accuracy. The estimated health risk calculated showed that the concentrations of chlorine (Cl) and iodine (I) were high in the order I > Cl with all very far above the maximum Upper Limit (UL) of the daily Recommended Dietary Allowance (RDA) for all life stages except for children below 8 years. Conclusion Mn is found in very high quantities in the diet consumed by the parents of babies. These children could be exposed to metabolic disorders or unexplained diseases in future without knowing their origin.

Background: Breast milk contains various micronutrients which nourishes a baby with nutrition, and therefore the endorsement for exclusive breastfeeding during the first six months after birth. Such micronutrients, if in excess, can have adverse effects on the baby. Objective: The levels of seven micronutrients in breast milk obtained from 27 lactating mothers in the Cape Coast Metropolitan area have been determined using Epithermal Neutron Activation Analysis (ENAA). This technique was used because it is suitable for performing both qualitative and quantitative multi-nutritional analyses on samples, and offers accuracies and sensitivities superior to those attainable by other methods. Materials and Methods: During the analysis, a- 3 mm thick flexible boron was used to cut-off thermal neutrons so as to assess epithermal neutrons, thereby creating an activation energy which measured the levels of micronutrients in the breast milk. The standard reference materials used were the International Atomic Energy Agency (IAEA)-336; IAEA-407, IAEA-350 and National Institute of Standard and Technology (NIST) USA SRM 1577b. The Relative standardization method was used in the quantification of the micronutrients, with an accuracy of about 94.7 %. The micronutrients are Sodium (Na), Magnesium (Mg), Potassium (K), Calcium (Ca), Manganese (Mn), Copper (Cu) and Iodine (I). Results: Except for iodine which had levels below the recommended dietary allowance (RDA), the remaining micronutrients had levels above the upper limit of the RDA, with Manganese being the highest. Conclusion: The levels recorded are directly linked to the food intake of the mothers, and therefore the need for pregnant and lactating mothers to be mindful about what they eat. Children could be exposed to metabolic disorders and diseases as a result of such high levels.

“…However, algae stand out because they are one of the best bioindicators of marine pollution [10] and they could be used as bioremediation treatments in contaminated environments [11][12][13], as support of other non-biological treatment methods like sorption by biochar, activated carbon, nanomaterials, among others [14,15]. Nevertheless, this is not the only application in which algae are used; they are also applied in biofuel production [16], as replacement of the traditional NPK fertilizer [17], and in improvements in aquaculture [18].…”

Toxic and Trace Elements in Seaweeds from a North Atlantic Ocean Region (Tenerife, Canary Islands)

et al. 2022

Canary Islands is a North Atlantic Ocean archipelago in the Macaronesian region that stand out for its great algae diversity and its climatic conditions. However, even in this low industrialised area, human activities tend to increase the marine pollution. Asparagopsis spp. and Liagora spp. algae are red algae frequent in the Canary Islands’ coasts. Therefore, they could be used as bio-indicators of marine pollution for trace elements. A total of 30 samples of both algae’s species from Tenerife’s southern coast, specifically in Playa Grande, Porís de Abona, in Arico (Tenerife, Spain) were used to determine trace element content (Mn, B, Ba, Cu, Cd, Co, Fe, Li, Mo, Ni, Pb, Sr, V, Zn, Al, Cr) through inductively coupled plasma atomic emission spectroscopy (ICP—OES). Highest Fe concentrations were found in Liagora spp. concentrations (1190 ± 1545 mg/kg dw) and Al (288 ± 157 mg/kg dw) was more significant in Asparagopsis spp. High concentrations of B were also registered in both species 80.2 ± 34.2 mg/kg dw and 77.9 ± 34.2 mg/kg dw, respectively. The recorded concentrations show a high contamination scenario in the collected area. Porís is known by its marine diversity and by its higher pollution levels, compared with other locations of Tenerife, due to the currents present on the Canary Island and its singular north orientation, actions must be taken to reduce pollution.
