The objective of this study was to assess Lebanese population exposure to trace elements (TEs) via white pita consumption. A survey of white pita consumption was achieved among one thousand Lebanese individuals, grouped into adults (above 15 years old, men, and women) and young people (6–9 and 10–14 years old). The most consumed pita brands, labeled B1, B2, and B3, were selected. Levels of TEs (i.e., As, Cd, Co, Cr, Hg, Ni, and Pb) in B1, B2, B3 pitas were measured. The highest contents of TEs in pitas were: Ni (1292 µg/kg) and Co (91 µg/kg) in B1; As (400 µg/kg) and Cd (< 15 µg/kg) in B2; Cr (363 µg/kg), Pb (260 µg/kg), and Hg (0.89 µg/kg) in B3. The pita brand B3 was the source of the highest TEs exposure, except for Ni for which it was B1. Daily exposures to TEs due to the fact of pita consumption were compared to safety levels. There were no safety concerns for Hg, Cd, Cr or Co (except the 95th percentile of 6–9 years old). An excess of the Ni tolerable daily intake was observed for the most exposed populations. The very low margins of exposure for As and Pb suggest a worrying risk for the Lebanese population.

This study was undertaken to estimate the contribution of meat and meat products consumption to the daily intakes of trace elements (Fe, Zn, Cu, Se), heme iron, and selected B vitamins (thiamine, riboflavin, niacin) in Italy. Meat and meat products were selected on the basis of their consumption frequency reported by the most recent nationwide dietary individual survey carried out in Italy (INN-CA study). The daily intakes of total iron and heme iron were 1.65 and 1.13 mg/person/day. Zinc intake was 3.65 mg/person/day. Beef made the main contribution to iron, heme iron, and zinc daily intakes. Copper daily intake was 107.3 mug/person/day, with meat products provided the highest contribution (40 mug/person/day). Daily intake of selenium (7.14 mug/person/day) was provided mainly by poultry consumption. Thiamine intake was 228 mug/person/day, and meat products were the main source (110 mug/person/day). Riboflavin intake was 136 mug/person/day, with both beef and meat products as the main contributors (40 mug/person/day). Niacin intake was 7.53 mg/person/day, and poultry was the main source (2.28 mg/person/day). Meat and meat products were a valuable source of micronutrients, supplying 47, 48, and 24% of zinc, niacin, and thiamin daily requirements, respectively, and over 10% of iron, copper, selenium, and riboflavin daily average requirement values of the italian RDAs calculated for the population involved in the survey (INN-CA study).

New Perspective

Building on Fielding’s idea of escalator regions as places where young people migrate (often temporarily) to get rapid career advancement, this paper proposes a new perspective on 'escalator migration' as it applies to frontier or remote regions in particular. Life events, their timing and iterations have changed in the thirty years since Fielding first coined the term ‘escalator region’, with delayed adulthood, multiple career working lives, population ageing and different dynamics between men and women in the work and family sphere. The object of this paper is to examine recent migration trends to Australia's Northern Territory for evidence of new or emerging 'escalator migrants'.

Infant’s feeding patterns are important for development and growth; therefore babies are very sensitive to toxic elements, mainly through their food, so in the present study, the concentrations and daily intake of some Toxic Elements (TEs); Lead (Pb), Arsenic (As), Cadmium (Cd), Mercury (Hg) and Aluminum (Al) were measured in different and random 60 dried infant foods {30 infant formula (0-6 months) and 30 milk-cereal based infant formula (6 months)} which obtained from various supermarkets and pharmacies. The analysis was done using Inductive Coupled Plasma - Mass Spectrometer (ICP-MS). It could be determined the lead, arsenic, cadmium, mercury and aluminum by mean values of 0.424±0.006, 0.205±0.003, 0.014±0.0001, 0.298±0.007and 0.464±0.029 mg/Kg in the examined infant milk formula samples and a ranged minimum to maximum concentrations of 0.114-0.177, 0.155-0.293, 0.014-0.015, 0.282-0.310 and 0.287-0.437 mg/kg, respectively in the examined milk-cereal based infant formula. Present study indicates that, the greater level of contamination of examined infant formula samples with toxic elements (lead and mercury) surpasses the maximum limit and Provisional Tolerable Daily Intake (PTDI) of these elements. Mercury is over PTDI (0.0005 mg/kg bw/day) in all milk-cereal based infant formula samples, also arsenic in all examined samples of this type of formula was exceed the maximum limit (0.05 mg/kg) of Indian standard. This investigation shows such types of infant formula need more amendment to set limit of more toxic metals for this sensitive group of population.

Minerals And Trace Elements

Background: Contamination of soil and agricultural products by heavy metals resulting from rapid industrial development has caused major concern. Dietary exposure to heavy metals has been associated with toxic and adverse health effects. The main threats to human health from heavy metals are associated with exposure to Pb, Cd and Hg. The aim of this study was to monitor the presence of heavy metals, minerals and trace elements in cereals consumed by Dhaka city residents. Methods: One hundred and sixty cereal samples were collected for eight (08) composited samples and analyzed for the determination of sixteen elements. Heavy metals were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and other elements were determined by Atomic Absorption Spectrometry (AAS). Results: The average concentrations of elements in cereals fall within the safe limit except for Pb, Cr, Na and Mg, which exceeded the safe limits. The daily intake of Cd (23.0 μg), Hg (63.0 μg) and As (13.6 μg) through cereals was below the risk level except for Pb (634.0 μg) and Cr (263.1 μg). The dietary intake of Na (1860.0 mg), Mg (347.0 mg) and Mn (4600.0 μg) exceeded the toxic level while K (829 mg) was below the RDA. Conclusion: As the main meal of average Bangladeshi people is boiled rice served with some vegetables, our findings indicate that the residents of Dhaka city are at risk from Pb and Cr contamination and their dietary need for some important minerals and trace elements is not fulfilled by cereals.

Migrant Domestic Workers

Persistent economic inequality between men and women, combined with differences in gender expectations and growing inequalities among women globally, has resulted in families “outsourcing” childcare by employing migrant domestic workers (MDWs). While studies have addressed the intimacy and complexity of “mothering” in such contexts, the agentic position of child-recipients of such care have seldom been explored. This article increases our understanding of care-relationships by examining their triangularity among children, MDWs, and mothers in Hong Kong. Drawing on in-depth interviews with young people who grew up with MDWs, alongside interviews with MDWs themselves, this article describes processes through which care work transforms into what Lynch describes as “love labor” in these relational contexts. In these contexts, commodified care from MDWs can develop, through a process of mutual trilateral negotiations, into intimate love-laboring relationships that, in turn, reflect larger dynamics of familial transformation that are endemic to “global cities.”

Food is a major source of minerals for humans. The main objective of this study was to determine the intake level of 10 essential macro- (Na, K, Ca, and Mg) and trace elements (Cu, Zn, Mn, Fe, Cr, and Se) with major food groups among young adults. Dietary intake of elements was evaluated using the 24-h dietary recall technique in combination with F-AAS and ICP-OES methods. A very high intake of sodium and a very low intake of calcium, combined with inappropriate sodium/potassium ratio, may be harmful to the health of the population. Dietary intake of trace elements was within the range of reference values in the subjects, with cereals being the major source of a majority of those elements, while meat (38% for Na), vegetables (25% for K), and milk products (75% for Ca) were the main contributors to the daily dietary intake of macroelements. PCA revealed several visible trends in the datasetAmong men, the intake of Zn, Cr Na and K was significantly correlated with the consumption of meat and vegetables, whereas Mg, Se, Fe and Cu with cereals and water and beverages. Among women, the intake of Mg was significantly correlated with the consumption of meat and vegetables.

Breast-fed infants in Bangladeshi villages were weighed at 1, 2, 6, 9 and 12 months. The concentrations of zinc and copper in the breast milk were measured and the daily intake of these elements calculated. Breast milk Zn concentration decreased over the year but was comparable with that found in developed countries. The calculated daily intake decreased from 17·7 to 8·0 μmol (10–30% of recommended dietary allowances (RDA); National Academy of Sciences, 1980). Breast milk Cu concentration also fell over the year and was lower than that reported from developed countries. Calculated daily Cu intake was 1·95–2·63 μmol (RDA 7·81–15·63 μmol). Deficiencies of trace elements may therefore be a problem in poorly nourished communities where breast feeding is continued for several years with only small amounts of additional food. Breast milk may not be adequate as the only source of infant nutrition after the first few months of life in Bangladesh.
