Eye and skin irritation tests using deep sea water-extracted minerals

Nasal, eye, and skin irritation in dockyard painters.

OBJECTIVES To determine whether the risk of irritant symptoms in painters is related to their exposure to paint. METHODS The prevalences of skin, eye and nasal symptoms were compared in 260 United Kingdom and 109 Chinese dockyard painters, 539 British community controls, and 255 Chinese dockyard controls, relative to their exposure to paints. RESULTS Painters showed an excess of irritant sy...

Skin irritation and corrosion.

Combined in vitro tests as an alternative to in vivo eye irritation tests.

Accurate methods that test the eye irritation potential of chemicals, which do not involve the use of animals, are needed to meet new regulatory standards. We evaluated the applicability and predictive capacity of five in vitro tests for eye irritation: the Hen's Egg Test-Chorioallantoic Membrane (HET-CAM) assay; the Chorioallantoic Membrane-Trypan Blue Staining (CAM-TBS) assay; the Fluorescein...

Nominally anhydrous minerals and Earth’s deep water cycle

Deep reservoirs of water incorporated as hydroxyl into solid silicate minerals of the Earth’s interior may contain the majority of the planet’s hydrogen and have acted as buffers to maintain ocean volume and continental freeboard over geologic time. Two tenths of one weight percent H2O in subducted oceanic crustal material and subsequently released to the hydrosphere from mid-ocean ridge basalt...

Khaki Drill and Skin Irritation

Sir,?The following facts may possibly be of interest to your readers and of use in cases similar to my own. For several years I suffered from an irritating skin disease which, without pathological examination of scrapings, was diagnosed variously as " tinea" or "lichen." Various doctors prescribed various ointments ?chrysarobin, benzoic, resorcin, salicylic, etc., etc., and iodine liniment, all...
