[7] All levels of government work together to help protect Canadians and the environment from any risks posed by pesticides and to ensure that pest control products do what they claim to on ...
Therefore, a pesticide with low toxicity and high exposure could pose a similar risk as a pesticide with high toxicity and low exposure. [35] Built-in safety factors are designed to take into account the potential variability of response, both within the same species (e.g., adults versus children) and between species (e.g., animals versus humans).
Many newer pesticides are derived from plants or naturally occurring substances (e.g.—nicotine, pyrethrum and insect juvenile hormone analogues), but the toxophore or active component may be altered to provide increased biological activity or stability. Applications of pesticides must reach their intended targets.

Pesticides can accumulate in bodies of water to levels that kill off zooplankton, the main source of food for young fish. [92] Pesticides can also kill off insects on which some fish feed, causing the fish to travel farther in search of food and exposing them to greater risk from predators. [90]
Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. [ 17 ]
