51. Adatorwovor R, et al. (2015). National Health and Nutrition Examination Survey (NHANES) We examined dietary calcium and phosphorus intakes across gender and older adult age groups and found that the mean intakes for calcium were lower and for phosphorus were higher than the recommended dietary allowances, resulting in overall lower calcium-to-phosphorus ratios. age | diet Calcium | Phosphorus Study subjects United States Calcium | Phosphorus Details

53. Padhi BK, et al. (2017). Burning of household fuels could be a major source of endotoxin in homes; we measured endotoxin levels in different size fractions of particulate matter (PM10, PM2.5, and PM1) in homes using LPG (propane) vs. biomass fuel (complex mixtures), and estimated the deposition of particle-bound endotoxin in the respiratory tract.

55. Sunyer J, et al. (2008). The aim of the present study is to assess the association between Hexachlorobenzene and other organochlorines compounds, and urinary porphyrin excretion during childhood, at an age with a more valid assessment of porphyrins than at birth, and without the confounding effect of other determinants occurring at adulthood.

57. Fessler MB, et al. (2017). Agricultural Lung Health Study (ALHS) | National Health and Nutrition Examination Survey (NHANES) We report an association between house dust endotoxin and leukocyte count in a national survey, and the finding was replicated in a farming population; peripheral leukocyte count may be influenced by residential endotoxin exposure in diverse settings.

58. Senofonte, et al. (2000). Hair samples of school children from several urban areas of Rome (Italy) were analyzed to determine the content of 19 minor and trace elements with the aim of assessing reference values (and these values are compared with data from other countries); significant differences were found for certain elements depending on age and sex. age | sex Elements Children | Study subjects Bulgaria|Canada|

59. Blaurock-Busch E, et al. (2011). We assessed a spectrum of trace elements and heavy metals in hair and urine of both autistic and control groups to focus on the participants' past and present exposure.

60. Park HS, et al. (2007). Hair samples of children from metropolitan and small cities in Korea were analyzed for 23 trace elements with the aim of assessing reference values; there was no significant difference in levels between metropolitan and small cities, but there were positive correlations between age and levels of zinc, calcium, sodium, phosphorus, manganese, lithium, and negative correlations for chromium, vanadium, and uranium. age Elements | Minerals Children Korea, Republic of hair Aluminum | Arsenic | Barium | Bismuth | Cadmium | Calcium | Chromium | Cobalt | Copper | Iron | Lead | Lithium | Magnesium | Manganese | Mercury | Molybdenum | Phosphorus | Potassium | Selenium | Sodium | Uranium | Vanadium | Zinc Details
61. Solomon GM, et al. (2006). We assessed potential human exposure to mold spores and endotoxin in New Orleans after the flooding of the city; unlike mold spores, the airborne endotoxin concentrations did not vary with flooded status or between indoor and outdoor environments.

62. Mendy A, et al. (2018). National Health and Nutrition Examination Survey (NHANES) In a population-based sample of U.S. adults, endotoxin levels in homes were associated with a self-reported history of CBE diagnosis and chronic bronchitis symptoms, with stronger associations among people sensitized to inhalant allergens.

63. Wang Z, et al. (2012). We examined the difference in airborne bioaerosol levels in residential indoor environments measured using a robotic personal sampling surrogate (PIPER Mk IV) and a stationary sampler equipped with identical sampling equipment. PIPER, which is designed to simulate resuspension of the dust from flooring by young children, measured significantly higher endotoxin concentrations compared to the stationary sampler.

66. Rubio-Andrade M, et al. (2011). A follow-up study on lead exposure in children living in a smelter community in northern Mexico indicates that blood lead levels have significantly decreased. This could be explained by environmental interventions by authorities and the smelter companies, normal changes in hygienic habits as children age, and lead redistribution from blood to hard tissues.
