What is chemical fate?
Chemical fate describes where a chemical goes when it gets out into the environment and how it might be chemically transformed in the process. Other chemicals are more likely to end up in lakes, rivers, groundwater, and oceans.
What is fate and transport?
Fate and transport analysis is defined as the study of how chemicals degrade and where chemicals travel in the environment when they are released intentionally or unintentionally.
What is environmental fate?
Environmental fate describes where a chemical or PPP will end up after it is used and released into the environment. Given the complexity of ecosystems, the possible environment fate of a chemical can be difficult to envisage.
Why is it important to understand the environmental fate of an organic chemical?
Environmental Fate and Behavior In order to assess the occurrence and the extent of exposure of a chemical in the environment and possibly its effect on the environment and living organisms, it is necessary to evaluate the chemical’s fate and its behavior in specific environmental compartments.
Why is fate and transport important?
ERT’s environmental scientists and engineers have significant experience in fate and transport of hazardous materials in the subsurface. Fate and transport models estimate the movement and chemical alteration of contaminants as they move through air, soil or water.
What is environmental fate and Behaviour?
Environmental fate and behaviour considers how substances behave in soil, surface water, sediment, groundwater and air. Key elements to assessing pesticides in the environment are: What the active substance breaks down into (referred to here as metabolites)
What is the fate of pollutants?
The fate of pollutants in the environment depends upon the ‘compartment’ in which they occur: air, water, soil, sediment (the ‘mud’ at the bottom of water bodies), or living organisms.
What is fate model?
Fate models can be integrated with, or loosely-coupled to, multi-pathway exposure models that describe the transfer of chemicals from the environment into the food and water ingested by humans, and water and soil that directly contacts the human skin.
What is the purpose of fate?
Traditional usage defines fate as a power or agency that predetermines and orders the course of events. Fate defines events as ordered or “inevitable” and unavoidable. This is a concept based on the belief that there is a fixed natural order to the universe, and in some conceptions, the cosmos.
