Asbestos can be found naturally in the air outdoors and in some drinkable water, including water from natural sources.

Cultural heritage collections contain many materials known to be hazardous to the environment and to human health. Some hazardous substances may be an integral part of the object (such as a toxic paint pigment or a naturally radioactive mineral sample), applied as a treatment after the object was made (such as a pesticide) or the result of material degradation (such as the exudation of ...
