Environmental persistent free radicals (EPFRs) are receiving growing concerns owing to their potentially adverse impacts on human health. Road dust is one important source of air pollution in most cities and may pose significant health risks. Characteristics of EPFRs in urban road dusts and its formation mechanism(s) are still rarely studied. Here, we evaluated occurrence and size distributions of...... hiện toàn bộ
A review of the iodine status of UK pregnant women and its implications for the offspringEnvironmental Geochemistry and Health - Tập 37 - Trang 619-629 - 2015
Sarah C. Bath, Margaret P. Rayman
Iodine, as a component of the thyroid hormones, is crucial for brain development and is therefore especially important during pregnancy when the brain is developing most rapidly. While randomised controlled trials of pregnant women in regions of severe iodine deficiency have shown that prenatal iodine deficiency causes impaired cognition, less is known of the effects in regions of mild deficiency....... hiện toàn bộ
The dangerous link between coal dust exposure and DNA damage: unraveling the role of some of the chemical agents and oxidative stressEnvironmental Geochemistry and Health - Tập 45 - Trang 7081-7097 - 2023

Exposure to coal mining dust poses a substantial health hazard to individuals due to the complex mixture of components released during the extraction process. This study aimed to assess the oxidative potential of residual coal mining dust on human lymphocyte DNA and telomeres and to perform a chemical characterization of coal dust and urine samples. The study included 150 individuals exposed to co...... hiện toàn bộ
Temporal and spatial variations of PM2.5 organic and elemental carbon in Central IndiaEnvironmental Geochemistry and Health - Tập 40 - Trang 2205-2222 - 2018
Rakesh Kumar Sahu, Shamsh Pervez, Judith C. Chow, John G. Watson, Suresh Tiwari, Abhilash S. Panicker, Rajan K. Chakrabarty, Yasmeen Fatima Pervez
This study describes spatiotemporal patterns from October 2015 to September 2016 for PM2.5 mass and carbon measurements in rural (Kosmarra), urban (Raipur), and industrial (Bhilai) environments, in Chhattisgarh, Central India. Twenty-four-hour samples were acquired once every other week at the rural and industrial sites. Twelve-hour daytime and nighttime samples were acquired either a once a week ...... hiện toàn bộ
Determinants of blood and saliva lead concentrations in adult gardeners on urban agricultural sitesEnvironmental Geochemistry and Health - Tập 44 - Trang 3493-3513 - 2021
Lindsay Bramwell, Jackie Morton, Anne-Helen Harding, Nan Lin, Jane Entwistle
Soil Pb concentrations at urban agriculture sites (UAS) commonly exceed recommended safe levels. There is a lack of evidence regarding uptake of Pb by gardeners using such sites for food crops. Our study aimed to elucidate whether gardening in soil with raised Pb levels results in Pb body burdens of concern to health, and to assess confounding factors influencing Pb body burden. Our cross-sectiona...... hiện toàn bộ
The investigation of metal concentrations in street dust samples in Aqaba city, JordanEnvironmental Geochemistry and Health - Tập 29 - Trang 197-207 - 2007
Omar Ali Al-Khashman
The concentrations of metals (Fe, Zn, Cu, Cr, Pb, Cd, Ni, Mn and Co) in 140 street dust samples were collected from Aqaba city, Jordan. These samples were determined using flame atomic absorption spectrophotometry after digestion with aqua regia. The highest levels of metal concentrations were found in the samples from heavy traffic. While the lowest levels of metal ions were noted in the street d...... hiện toàn bộ
