“…Since the deviation from the certificate value was less than 10% for all elements, the NAA method used in this case had good precision. This finding means that the NAA method can be used for analyzing samples and providing a valid value [24][25]. Furthermore, Table 1 also showed that the experimental values for all tested elements did not significantly differ from the certified values, indicating that the NAA used in this experiment was highly accurate.…”

“…NIST SRM 695 was chosen to determine the method's precision and accuracy because the reference material contained the certificate value of all analyzed elements. The relative error, expressed as the percentage of the standard deviation of the mean of three determinations [24], was below 10% for all elements. The Relative Standard Deviation (RSD) was given as the percentage deviation from the certified value material [25].…”

Assessment of Multi-Nutrients and Heavy Metals in Inorganic Fertilizers Widely Used by Indonesian Farmers Using NAA

2022

This research aims to determine the concentration of multi-nutrients and heavy metals and investigate the correlation among them in the seven inorganic fertilizers in Indonesia. Sample analysis was carried out using the NAA method. The highest concentrations of macro-nutrients were K (36.54 %) and Cl (18.09%) found in the KCl sample, while Ca (23.01%) was observed in the TSP sample. In the case of micro-nutrients, the highest concentrations of Se (0.36 mg/kg), Ti (597 mg/kg), Br (1.84%), and Ni (2.46 mg/kg) detected in the NPK sample. Meanwhile, the highest concentrations of Co (19.57 mg/kg) and Na (1.40%) were measured in the ZA sample, while Mg, with the highest concentration of 1.78%, was found in the KMgS sample. The micro-nutrients with the highest concentration detected in the TSP sample were Cr (45.96 mg/kg), Zn (342.6 mg/kg), and Mn (1331 mg/kg). Non-essential elements such as U, V, La, Sb, Sm, Th, Hf, Sr, Cs, Tb, Sc, Rb, Ta, and Eu were also detected in the fertilizer samples with the highest concentrations in the TSP sample. Statistical tests of multi-nutrient and heavy metals concentrations indicated that multi-nutrient and heavy metals in fertilizers are complex.

“…Os autores salientaram que o risco de interferência nas concentrações de elementos nos fungos liquenizados oriundo do substrato das cascas de árvore, pode ser reduzido com a aplicação do biomonitoramento ativo e foi concluído que tanto as cascas como os fungos liquenizados apresentaram potencialidade para atuar como biomonitores da poluição atmosférica na região de estudo e auxiliar na caracterização de fontes de emissão poluidoras (BOUHILA et al, 2021).…”

“…O uso das cascas de árvore tem se tornado cada vez mais popular em trabalhos de biomonitoramento passivo da poluição atmosférica (HOFMAN et al, 2017;MOREIRA et al, 2018). Apesar de não ser capaz de acumular poluentes atmosféricos tão facilmente como os fungos liquenizados, musgos e plantas epífitas, o principal fator favorável ao uso das cascas no biomonitoramento passivo é sua ampla disponibilidade (PACHECO et al, 2001;CHRABĄSZCZ e MRÓZ, 2017;BOUHILA et al, 2021). Contudo, nas publicações sobre o uso de cascas de árvores no biomonitoramento ativo ainda são bastante escassas.…”

Instrumental neutron activation analysis (INAA) of zinc concentrations in scalp hair and fingernails samples of Algerian females with breast cancer

et al. 2021

View full text Add to dashboard Cite

In the present work, zinc levels were measured in scalp hair and fingernails in order to identify potential risk factors for breast cancer. The samples were collected from 40 Algerian breast cancer female patients and from 20 normal subjects matching the same age range. The concentration of zinc was analyzed using Instrumental neutron activation analysis technique (INAA). In scalp hair samples it was found in the range 119–792 μg/g for the normal subjects and in the range 82–806 μg/g for the patients, with an increase rate of 10.9%. The range of concentration of zinc in fingernails was found between 89 and 247 μg/g for normal subjects and between 75 and 276 μg/g for the patients with an increase rate of 2.5%. The influence of age on zinc concentration was also investigated. The obtained results show some consistency with those obtained by other groups.
