Evidence of aluminium accumulation in aluminium welders.
Using atomic absorption spectrometry the aluminium concentrations in blood and urine and in two iliac bone biopsies obtained from welders with long term exposure to fumes containing aluminium were measured. The urinary excretion of two workers who had welded for 20 and 21 years varied between 107 and 351 micrograms Al/l, more than 10 times the concentration found in persons without occupational...
متن کاملAluminium accumulation and immunosuppressive effect in recipients of kidney transplants.
Aluminium that has accumulated in the body is thought to have a generalised cytotoxic effect. A prospective study of aluminium accumulation in bone-that is, subclinical aluminium toxicity--was carried out in 94 recipients of kidney allografts, who were followed up for three years. Subclinical aluminium toxicity was found in 66 patients. A significantly smaller proportion of patients with alumin...
متن کاملDoes oral aluminium cause toxicity? Do oral aluminium phosphate binders cause accumulation of aluminium to toxic levels?
Background We wished to determine the risk of Al toxicity in HD patients receiving Alucaps but never exposed to contaminated dialysate water. Methods HD patients only treated with Reverse Osmosis(RO) treated dialysis water with either current or past exposure to Alucaps were given standardised DFO tests. Post-DFO serum Al level >3.0μmol/L was defined to indicate toxic loads based on previous bo...
متن کاملDo oral aluminium phosphate binders cause accumulation of aluminium to toxic levels?
BACKGROUND Aluminium (Al) toxicity was frequent in the 1980s in patients ingesting Al containing phosphate binders (Alucaps) whilst having HD using water potentially contaminated with Al. The aim of this study was to determine the risk of Al toxicity in HD patients receiving Alucaps but never exposed to contaminated dialysate water. METHODS HD patients only treated with Reverse Osmosis(RO) tr...
متن کاملAccumulation of Aluminium and Physiological Status of Tree Foliage in the Vicinity of a Large Aluminium Smelter
A pollution gradient was observed in tree foliage sampled in the vicinity of a large aluminium production facility in Patagonia (Argentina). Leaves of Eucalyptus rostrata, and Populus hybridus and different needle ages of Pinus spec. were collected and concentrations of aluminium (Al) and sulphur (S) as well as physiological parameters (chlorophyll and lipid oxidation products) were analyzed. A...
