What does it mean if pesticides are accumulative?

When pesticides are described as accumulative, it indicates that these substances can build up in the tissues of living organisms over time, including in both animals and humans. This accumulation can result from repeated exposure, leading to higher concentrations of the pesticide in the body than were initially present in the environment. This is particularly concerning because, as these substances accumulate, they may reach toxic levels, potentially causing various health effects or disrupting biological processes.

Understanding this characteristic is important for pest control professionals, as it underscores the need for careful application and monitoring of pesticide use. It highlights the risk associated with long-term exposure to certain chemicals, which may not be immediately evident but can result in significant health impacts over time.
