Our food supply is slowly accumulating a variety of non-biodegradable pesticides. The studies I’ve read show that traces can be found in a surprising amount of foods. There are reasons for the accumulation and a few different compounds that make up these pesticides. It’s scary to think about how much we’re ingesting on a daily basis, but I’d like to see the conversation move beyond, “Should I be eating this?” to “What can we do to prevent it?”.
How Non Biodegradable Pesticides come into the Food Chain?
Pesticides: Pesticides stay in the environment for years after use. They accumulate in soil and water and are transported to plants of all types through irrigation and fertilizers. They also enter our bodies when we breathe in contaminated air or eat contaminated food.
Heavy metals: Heavy metals like lead, mercury, and cadmium are often released from industrial processes such as mining and smelting. They enter the environment through point source pollution or non-point source pollution. Point source pollutants come from a known source (for example, a factory), while non-point source pollutants come from an unknown source (such as run-off from a field).
Once these chemicals are introduced into the environment, they move up the food chain, which means that animals that eat other animals eventually eat them too. This is why many fish contain high levels of heavy metal contaminants such as mercury.
Minimize the use of toxic pesticides
In an effort to minimize the use of these toxic pesticides, farmers are beginning to investigate alternative methods, such as biological control. In this method, beneficial insects are able to control the population of harmful insects in a controlled environment. This can be a very effective way to reduce the number of pesticides needed and still protect the crops.
However, there are drawbacks to using this method as well. One major drawback is that it requires large amounts of land space for the production of beneficial insects. The second drawback is that it is difficult to scale up this method since it relies on small areas being planted with non-biodegradable pesticides.
While there are some drawbacks to using non-biodegradable pesticides in agriculture, there are also many benefits. These include reduced soil erosion, decreased water contamination, and a decrease in chemical residue in food products. The amount of chemical residue found in fruits and vegetables has decreased dramatically over the last decade.
Unfortunately, there are some serious drawbacks associated with using non-biodegradable pesticides as well. Some of these include increased soil acidification and an increase in the number of insect pests that can attack crops.
