“…In some cases, just a dilution step can be enough, as can be exemplified by fluorine determination 32,34 in water without pretreatment for further analysis by ICP-QQQ. 32,34 Moreover, the analysis of crude oil, 44 drug substances, 22 polyglycerol, 154 seaweed, 23 and urine 8 samples can be performed employing only a preliminary dilution with a suitable solvent (for fluorine, 22 chlorine, 22,44 bromine, 22 and iodine 8,22,23,109 determination by ICP-MS). On the other hand, only a filtration step using specific membranes can be required for further iodine determination in milk, 85 urine, 85 and water 49 by ICP-MS.…”

“…Hence, the use of an internal standard (IS) has been a well-documented strategy to overcome instrument instability and non-spectral interferences, as well as to increase the precision of the measurements. 77 Internal standards have mainly been used for bromine and iodine determination, and several elements have been evaluated for this purpose, such as Te 8,23,37,46,47,51,52,54,65,72,76,78 and Sb 72,75,76 for iodine determination. On the other hand, Cs, 50,56,68,79 , In [80][81][82][83] Sb, 75,84 Sc, 84 Te, 65 and Y 46,47 have been applied for bromine determination.…”

“…67 Tellurium seems to be a good alternative when determining bromine and iodine by ICP-MS, due to its stability in both NH 4 OH and TMAH solutions, as it has a similar m/z value and ionization energy to iodine. 8,23,51,52,65 In this way, this element has been the IS of choice in the majority of studies regarding iodine determination. 8,52,65 However, it was reported that the sample pH had an influence on both 126 Te and 127 I signals, which can be overcome by mixing the sample and IS solutions online during the determination step.…”

Rationale In this review, works published in the past 25 years for fluorine, chlorine, bromine, and iodine determination in several matrices by inductively coupled plasma mass spectrometry (ICP‐MS) were covered. Usually, the determination of halogens has been performed by ICP‐MS using a previous sample preparation step or, more recently, by direct analysis of solid or liquid samples. Methods Methods based on combustion, extraction, pyrohydrolysis, sample dilution in organic or aqueous medium, and wet digestion, among others, are discussed. Moreover, the recent applications of methods based on laser ablation (LA) and electrothermal vaporization (ETV) coupled to ICP‐MS are discussed. Results The main challenge for methods using sample preparation has been to obtain a final solution compatible with ICP‐MS, as well as to overcome problems related to analyte losses and contamination. Interferences due to the presence of dissolved organic compounds in solution, enhancement or suppression of ionization of analytes, and related matrix effects have been of concern when using ICP‐MS. For the determination of halogens by ICP‐MS using LA and ETV systems, some limitations related to the difficulty of calibration are pointed out, impairing the widespread use of this approach. Conclusions A critical view is presented for further halogen determination by ICP‐MS, mainly for matrices considered difficult to digest using conventional protocols.

“…A SES score has been calculated based on the education level, major professional occupation and income [17] [18]. Thus, two levels were adopted for each Open Journal of Epidemiology of its variables with partial scores of 0 and 1 respectively (education level ≤ primary versus education level > primary), (non-remunerated versus remunerated), (income < guaranteed inter-professional minimum wage (GIMW) versus income ≥ GIMW (GIMW is ≈ US$80 in 2014)).…”

Aims: Diabetes is a major public health problem in low and middle-income countries. This study 1) estimated prevalence and factors associated with hyperglycemia in Benin, and 2) assessed the treatment quality of diabetes. Methodology: A cross-sectional research was conducted with two components. The First component has included 4954 subjects aged (18-69) randomly selected in Mono/Couffo and Donga regions. Data were collected according to WHO's STEPS approach. Capillary blood glucose was measured using the automat Cardiocheck  PA. The Second component considered Public Health Centers (PHCs) within the study regions. Health system established for diabetes control, healthcare practices and the level of involvement of the Public Healthcare Providers and community actors in the management of diabetes have been explored. Findings: A total of 4775 subjects participated in the first component with a predominance of women (56.8%), rural residence and aged (<45 years). Prevalence of hyperglycemia was 9.2%. Age ≥ 30 years, Fon ethnic groups and related, obesity, hypercholesterolemia, and inadequate intake of fruits and vegetables were positively associated with hyperglycemia. The second component has underscored a mismatch of facilities, processes and quality healthcare. Conclusion: Diabetes prevalence goes increasingly in Benin when its management is inadequate in PHCs. Prevention and control actions should be strengthened.
