POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre-  existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.  

EYE

  Although the material is not thought to be an irritant, direct contact with the eye may produce transient discomfort characterized by tearing or conjunctival redness (as with windburn).  

SKIN

  Skin contact with the material may be harmful; systemic effects may resultfollowing absorption.  The material is not thought to be a skin irritant (as classified using animal models). Temporary discomfort, however, may result from prolonged dermal exposures. Good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  

INHALED

  The material is not thought to produce respiratory irritation (as classified using animal models). Nevertheless inhalation of the material, especially for prolonged periods, may produce respiratory discomfort and occasionally, distress.  

CHRONIC HEALTH EFFECTS

  There is ample evidence that this material can be regarded as being able to cause cancer in humans based on experiments and other information.  

  Primary routes of exposure are by skin contact/absorption and  inhalation of metal fumes on overheating. Excessive fumes of copper and zinc  oxide can cause metal fume fever with symptoms similar to those of influenza,  often appearing after a latent period of up to 10 hours. The symptoms will  normally disappear after 24 hours with rest. Even short exposures to cadmium  oxide fume can lead to pulmonary oedema and may be fatal.  WARNING: Available studies indicate that occupational exposure to cadmium in  some form (possibly the oxide), increases the risk of prostrate cancer in  man. In addition, one of these studies suggests an increased risk of  respiratory tract cancer.            [ILO Encyclopaedia]  Excessive inhalation of fumes or dust can produce inflammation of  respiratory tract and lung tissue, causing bronchitis, pneumonitis, etc.  Chronic exposure can produce kidney damage and emphysema.
