2. How Do Pesticides Impact the Environment?

Pesticides pose significant risks to the environment through several key pathways:

2.1. Water Contamination

Pesticides can contaminate surface and groundwater through runoff and leaching. This pollution harms aquatic life and can make water unsafe for human consumption. The U.S. Geological Survey (USGS) has found pesticides in over 90% of water and fish samples from streams across the country.

2.2. Soil Contamination

Pesticides can persist in the soil, affecting beneficial microorganisms and soil fertility. This can disrupt the natural nutrient cycle and reduce the soil’s ability to support plant growth. Studies have shown that heavy pesticide use can lead to a decline in beneficial soil microorganisms.

2.3. Air Contamination

Pesticides can volatilize and drift from treated areas, contaminating the air and affecting non-target vegetation. This drift can spread pesticides over long distances, impacting ecosystems far from the application site. Research indicates that a significant percentage of applied pesticides can volatilize into the atmosphere.

2.4. Harm to Non-Target Organisms

Pesticides are often toxic to a wide range of organisms beyond the intended pests, including beneficial insects, birds, fish, and other wildlife. This can disrupt ecosystems and reduce biodiversity. The EPA has documented numerous cases of pesticide-related harm to non-target species.

3. What Specific Types of Pesticides Are Most Commonly Used and What Are Their Known Environmental Impacts?

Commonly used pesticides include insecticides, herbicides, and fungicides, each with distinct environmental impacts:

3.1. Insecticides

Insecticides like organophosphates and neonicotinoids are used to control insect pests but can harm beneficial insects such as bees and butterflies. Neonicotinoids, in particular, have been linked to declines in bee populations, which are crucial for pollination. According to the Xerces Society, neonicotinoids are a leading cause of pollinator decline.

3.2. Herbicides

Herbicides like glyphosate are used to control weeds but can also harm non-target plants and aquatic life. Glyphosate, the active ingredient in Roundup, has been shown to have toxic effects on fish and disrupt aquatic ecosystems. Studies have indicated that glyphosate can cause physiological stress in fish.

3.3. Fungicides
