Asthma due to aluminium soldering flux.
copper as a material for electric cables. A previous survey of respiratory complaints after the use of this particular flux had failed to show any objective change in lung function, and the present cases are the first to be reported. Both subjects have been investigated by means of serial spirometry, peak flow rates, and body plethysmography following inhalation of small amounts of flux fumes; ...
متن کاملOccupational dermatitis from soldering flux.
The aim of this study was to determine the specific agent responsible for eczema on the forearms of 2 electronic assemblers who cleaned out a flux-spraying unit once a week. Soldering flux can be a source of skin irritation as well as allergy. Patch test with dried flux residue (as is) and rosin in dilution series of 20%, 10%, and 1% in olive oil was performed. Readings were taken on day 2 and ...
متن کاملUpper airway irritation and small airways hyperreactivity due to exposure to potassium aluminium tetrafluoride flux: an extended case report.
OBJECTIVES 22 workers, exposed to potassium aluminium tetrafluoride used as flux for soldering aluminium, were studied as clinical outpatients for symptoms of irritation of the nose, eye, skin, and airways. METHODS 16 volunteered for spirometry with methacholine provocation test including a test for small airways function by volume of trapped gas (VTG). RESULTS Median (range) latency time b...
متن کاملOccupational asthma due to a widely used soft solder flux not containing colophony.
A 19 year old woman presented with symptoms suggestive of occupational asthma. The causative agent was thought to be a soft solder flux, which did not contain colophony. The diagnosis was established by specific inhalation challenge tests, which demonstrated both late asthmatic reactions and short-lived increases in airway responsiveness.
متن کاملDecoherence of flux qubits due to 1/f flux noise.
We have investigated decoherence in Josephson-junction flux qubits. Based on the measurements of decoherence at various bias conditions, we discriminate contributions of different noise sources. We present a Gaussian decay function extracted from the echo signal as evidence of dephasing due to 1/f flux noise whose spectral density is evaluated to be about (10(-6)Phi0)2/Hz at 1 Hz. We also demon...
