Reaction, allergic atmospheric

Dipped Goods. Gloves with and without cloth support are a typical example. Unsupported appUcations involve specialty medical gloves and weather balloons. Eor CR to compete with less expensive natural mbber, it must provide added value. Natural mbber medical examination gloves contain proteins that can cause an allergic reaction in both patients and medical personnel. Polychloroprene gloves avoid the problem for those individuals, but are too expensive for general use. Natural mbber weather balloons have less lift than CR balloons and are rapidly attacked by ozone in the upper atmosphere. 

Ethylenediamine (1,2-diaminoethane), once described as God s gift to the coordination chemist , is commercially available either as the anhydrous amine (m.p. 8.5 °C) or the monohydrate (m.p. 10 °C). Both forms are clear fuming liquids at room temperature and these readily absorb carbon dioxde from the atmosphere. The vapor can cause an asthmatic allergic reaction after repetitious exposure. 

Skin sensitization An immunologically modulated cutaneous reaction to a substance or chemical by an animal. Response by humans to skin sensitization is observed in the form of erythema, edema, papules, pruritis, bullae, and vesicles, as with allergic contact dermatitis Smog Extensive atmospheric contamination by aerosols the term is derived from combining the terms smoke and fog ... 

Seasonal allergic rhinitis and/or conjunctivitis, more commonly known as hayfever, are allergic hypersensitivity reactions in the nasal mucosa and the conjunctiva of the eye associated with the presence of pollens in the atmosphere in the summer months. 

Absorption route Can enter the body by inhalation or mgestion. Evaporation negligible at20 C. but harmful atmospheric concentrations can build up rapidly in aerosol form. Immediate efiecis Irritates the eyes, skin and respiratory tract. Dermatitis and allergic reactions (eczema and asthma) are common. Headache, drowsiness, lowering of pulse rate and body temperature. ...
