Biochemical Oxygen Demand is the amount of dissolve oxygen needed by aerobic biological organisms to break down organic material present in a given water sample as certain temperature over a specific time period.

Vector Borne Diseases are transmitted among their human, animal, or plant hosts by arthropods, usually insects. A broader definition of vector borne disease recognizes that other animals can serve in the role of infectious disease vector by harboring pathogens that cause disease only in susceptible populations.
