What are persistent pesticides?
Persistent pesticides are chemicals that remain in the environment and can accumulate over time in soil, water, and organisms. These pesticides do not easily degrade, which can lead to long-lasting environmental and health impacts. Examples include organochlorine pesticides like DDT and chlordane.
What are pesticides made from?
Pesticides can be made from synthetic chemicals, natural products, or a combination of both. Common synthetic pesticides are derived from chemicals like organophosphates, carbamates, and pyrethroids, while natural pesticides can be sourced from plants (e.g., neem oil) or microbes (e.g., Bacillus thuringiensis).
What is the chemical equation for pesticides?
There isn't a single chemical equation for pesticides, as they can be composed of different active ingredients. Pesticides typically contain chemicals that target specific pests or regulate their growth. Some common types of pesticides include insecticides, herbicides, and fungicides, each with their own unique chemical composition.
What types of pesticides reduce bioaccumulation?
Pesticides that are easily broken down in the environment, have low persistence, volatility, and tendency to accumulate in living organisms are less likely to contribute to bioaccumulation. Examples include microbial pesticides, botanical pesticides, and certain biopesticides that have specific target organisms and low environmental persistence.
How do pesticides contaminate groundwater?
Pesticides can contaminate groundwater when they are applied to fields and leach through the soil into the groundwater. Rainfall or irrigation can help move the pesticides deeper into the ground where they can reach the groundwater. Once in the groundwater, pesticides can persist for a long time and potentially impact drinking water sources.

How spraying pesticides on your lawn could affect communities downstream in your water shed?

How might pesticides get from a garden to nearby river?
By runoff of rain water or irrigation water.
How do pesticides get into ponds?
Rain water washes it off whatever people put it on and gravity leads it to water.
Why would water plants contain DDT?
Some of the pesticides sprayed on farm crops wash off in the rain and get into the waterways. The water plants absorb the pesticides.
What factors influence the effectiveness of a pesticide rain light wind?
The effectiveness of a pesticide can be influenced by factors such as the timing of application in relation to rain, as rain can wash away the pesticide before it has a chance to work. Light can affect pesticide breakdown rates and efficacy, with some pesticides being degraded by sunlight. Wind can also impact the application of pesticides, as it can cause drift and uneven distribution of the pesticide.
What three threats to the health of trees in the US?
Acid rain, herbicides, pesticides, and insects are things that can threaten trees. The one factor that affects all of them, around the world besides deforestation, is acid rain.
What are disadvantages of applying pesticides?
You can be killing millions of living things, no matter where you spray the pesticide there are several things that die. Certain other insects are on a plant when you apply a pesticide, and that could kill them and the bad insect. When it rains, the pesticides are carried away with the rain, going to the ocean, polluting the ocean and also killing coral. THere are still millions of other disadvantages of using pesticides.
Is food better for your health with pesticides or without pesticides?
