This paper presents some of the properties of commercially manufactured laminated flooring having magnesium oxide substrate. Laminated flooring samples with thin veneer of walnut wood and linoleum were tested for their bending characteristics, internal bonding strength, thickness swelling, and surface roughness. The highest modulus of elasticity value of 583,000 psi was found for the samples lo...

A married couple presented with an illness typical of allergic alveolitis. A careful search of their home revealed a leak in the central heating system with a heavy fungal growth on wet flooring and linoleum. Two species of Penicillium, P chrysogenum and P cyclopium, were isolated from floorboards, linoleum, and settle plates. Antibodies against both these fungi were demonstrated in the serum o...

Moderate levels of dioctyl phthalate, hydrogen chloride and carbon monoxide are features of ambient air in production of linoleum, polyvinylchloride decorative filv and in other modern plastic materials production shops. The workers were diagnosed as having latent signs of neurotoxicity--vegetative dysfunction with prevalent parasympathetic tone and inactive polyneuropathy shown by electroneuro...
