Enlarging or increasing by successive addition.

Augmenting, gaining, or giving force, by successive additions; as, a cumulative argument, i. e., one whose force increases as the statement proceeds.

Changes that increase by multiplying ranges of negative-neutral-positive values on a pyramid structure, like the trunk-limb-branches of a tree.

increasing by successive addition; "the benefits are cumulative"; "the eventual accumulative effect of these substances"

injuries that develop gradually over periods of weeks, months, or years as a result of repeated stress.

Often the effects of repeated exposures to chemicals are greater than single exposures. The cumulative effect is what occurs from repeated exposures over time. This can include exposures to one chemical over time, or exposures to multiple chemicals in a short amount of time.

Additive or increased effect or response of an organism to repeated pesticide exposure (repeat doses may be in different forms).

Additional exposure rather than repeated exposure. For example, a one-hour exposure of HD followed within a few hours by another exposure of one hour, had the same effect as a single exposure lasting for two hours.
