Pesticides Environmental Effects

Pesticides, a substance used for destroying organisms that are harmful to cultivated plants, are extremely damaging to the environment, and can be detrimental to human health. Pesticides are typically used on farms, and over 1 billion tons of pesticides are used each year. Pesticides can lead to air pollution, after pesticides are sprayed on plants, winds can pick up the chemicals, leading the chemicals to remain in the air, which can potentially harm wildlife. A solution suggested that opposes the harmful chemicals is the use electromagnetic waves to repel small rodents. These electromagnetic devices claim to affect the nervous system of small rodents, which allows them to stay away from said area. A new solution is to combine ultrasonic waves with electromagnetic waves to repel pests, the ultrasonic waves will produce a frequency that cannot be heard by humans, but bugs will hear as a warning. The electromagnetic waves will be used to affect the nervous system of the bugs, but since their nervous system isn 't in affected the same way as small rodents, which is what the electromagnetic waves are usually used for, the ultrasonic waves will be combined to create a …show more content…
Hall invented Ultrasonic Pest control, “A device for generating and radiating ultrasonic sound waves for the control of pests such as rodents [and] insects” (Lester B. Hall, 1984). The sound generator consists of a plurality of transducers placed in two groups working in two frequency ranges in a manner providing a complex output in the form of a unsystematic pattern of frequencies and volume peaking in the ultrasonic frequency range (Lester B. Hall, 1984). In short, Ultrasonic pest control works by using high frequency sound waves that chase away unwanted pests (Barb Ogg, 2010). The waves emitted by the ultrasonic pest control device are a “high frequency waves which are not audible to human ears. But, they can be heard by rodents and insects.” (Mayuri Kulkarni,
