Harmful Effects of Pesticides on Water Bodies

Chemical Runoff

Pesticides sprayed on fields can wash into water bodies through rain or irrigation, contaminating the water with toxic chemicals that disrupt the delicate balance of aquatic ecosystems.

Aquatic Toxicity

Pesticides like herbicides, insecticides, and fungicides can be highly toxic to aquatic organisms, affecting fish, amphibians, and other aquatic life, leading to population decline and imbalances.

Bioaccumulation

Toxic pesticides accumulate in organisms over time, concentrating as they move up the food chain. This process magnifies the harm, potentially affecting animals and humans who consume contaminated aquatic life.

Algae Blooms

Pesticide runoff can trigger excessive nutrient levels in water bodies, leading to harmful algae blooms. These blooms deplete oxygen levels, harming aquatic creatures and disrupting the ecosystem.

Food Chains

Pesticides can eliminate certain aquatic species that form the foundation of food chains. This disrupts the entire ecosystem, leading to cascading effects on other organisms.
