an organic domain/matrix, in which they move into that organic environment because it
is much more compatible with them.
b. In regards to synthetic organics: chemicals interact with soil organic matter and slow
or arrest their movement.
i. The lower the water solubility, usually the stronger the interaction, the slower the
chemical movement.
What is partitioning? - Answer✔️✔️-When the chemical will distribute between the
organic and aqueous phases.; The organic colloid behaves like an organic solvent.
Understand the basic relationship between the water solubility of organic chemicals and
the strength of interaction with organic colloids. - Answer✔️✔️-Organic chemicals tend to
partition into the organic domain/sediments. Examples of this are pesticides, DDT, and
Toxaphene. (Persistence).
Understand basically how hydrophobic organic compounds accumulate in organisms. -
Answer✔️✔️-a. These chemicals are highly hydrophobic, so they don't like to be in
aqueous environment; it will accumulate in the fatty tissues of organisms. It will avoid
blood.
b. The "affinity" for carbon-based environments can lead to bioaccumulation, particularly
of poorly water soluble organic contaminants.
c. Lipid Tissue in organisms is principally composed of carbon and hydrogen.
Triglycerides are the most common. They are the main ingredient of fatty, or adipose
tissue, and are stored in fat droplets inside of adipose cells.
d. Hydrophobic organic compounds "prefer" the environment of the lipid tissues
(lipophilic).
