She also highlighted the problem of pests becoming resistant to pesticides.

The book has 40 contributors, mainly academics from a wide range of disciplines.
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]

Leaching is affected by the soil, the pesticide, and rainfall and irrigation.

[22] There can be acute effects immediately after exposure or chronic effects after continuous low-level, or occasional exposure. [23] Maximum residue limits for pesticides in foodstuffs and animal feed are set by many nations. [24]
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
