Gallium highly reactive (rubidium and caesium) nor highly toxic (mercury) and can therefore be used in metal-in-glass high-temperature thermometers. It is also notable for having one of the largest liquid ranges for a metal, and for having (unlike mercury) a low vapor pressure at high temperatures. Gallium's boiling point, 2673 K, is more than eight times higher than its melting point on the absolute scale, the greatest ratio between melting point and boiling point of any element. Unlike mercury, liquid gallium metal wets glass and skin, along with most other materials (with the exceptions of quartz, graphite, and Teflon), making it
Toxic colonialism term may also be applied to exploitation of Native American reservations, where differing environment regulations allow the land to be more easily used for dump sites. It is important to distinguish the difference between toxic colonialism and environmental racism. Toxic colonialism is the practice of targeting poor communities of color in developing nations for waste disposal and/or experimentation with risky technologies. Environmental racism is the inequitable distribution of environmental hazards based on race. In other words, toxic colonialism can be seen as “micro” as it focuses on a specific area or group of people. Environmental racism can be seen as
