Global distillation
Global distillation
Global distillation (pronunciation: /ˈɡloʊbəl dɪstɪˈleɪʃən/) is a scientific process that involves the volatilization and atmospheric transport of compounds to different parts of the globe. This process is also known as the grasshopper effect.
Etymology
The term "global distillation" is derived from the words "global", meaning worldwide, and "distillation", which refers to the action of purifying a liquid by a process of heating and cooling. The term reflects the process's ability to distribute pollutants around the globe through atmospheric transport.
Process
Global distillation involves several steps. First, pollutants are released into the atmosphere, where they can be transported by wind and air currents. These pollutants can then undergo deposition and revolatilization, allowing them to be transported further. Over time, these pollutants can become globally distributed, leading to their presence in remote areas far from their original source.
Related Terms
- Persistent Organic Pollutants (POPs): These are organic compounds that are resistant to environmental degradation. They can be globally distributed through the process of global distillation.
- Bioaccumulation: This is the accumulation of substances, such as pesticides or other chemicals, in an organism. Bioaccumulation occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost or eliminated by catabolism and excretion.
- Biomagnification: This refers to the process by which the concentration of a substance, such as a heavy metal or pesticide, increases in an organism over time, due to its persistence in the environment and its tendency to bioaccumulate.
