“Ancient Romans killed insect pests by burning sulfur and controlled weeds with salt. In the 1600s, ants were controlled with mixtures of honey and arsenic. By the late nineteenth century, U.S. farmers were using copper acetoarsenite (Paris green),calcium arsenate, nicotine sulfate, and sulfur to control insect pests in field crops” (Delaplane, 1996). DDT was developed as the first modern synthetic insecticides in the 1940s. DDT was initially used to treat malaria, typhus, a...

- When pondering on the fears associated with foods normally digested today, one may invoke up depictions of diet borne disease or famished families in a distant Third World nation. Although conditions such as these are unfortunate, individuals in industrialized countries frequently inquire where their meal originated from and what it entails, but seldom go beyond that thought. Many forget a crucial element that goes in the preparation of produce they just bought, and that is pesticides. Pesticides are chemical compounds typically sprayed on crops to help eliminate bugs by containing an unwanted taste or creating a disease within the bug....

- Agriculture is the most fundamental resource of society. Without it, humans could not live, especially in the ways we do now where people reside in cities. This means that those cities could not exist without large scale agriculture to sustain them. Since agriculture is such a necessity, people have developed methods to gain more from their land. One of the many solutions besides machinery they have developed to produce higher crop yields is through the use of pesticides. However, those pesticides which have resulted in high crop yields have come at price, and that is human health itself.... [tags: public health, epa, depression, suicide]

- Pesticides are an enormous benefit to society when used properly. Crop production is increased, produce is preserved, and infestations and exotic species are controlled. There are over a billion pounds of pesticides used annually in the US with over 20,000 marketed products. Unfortunately, it is estimated that there are 10,000 to 20,000 people diagnosed with acute cholinergic syndrome from pesticide poisonings that occur every year in the United States.

- Putting Aside Pesticides There are 2.5 billion pounds of pesticides being applied to agricultural products each year in the United States. This is ten times more than was applied forty years ago.

- Pesticides: What are they. Pesticides are chemicals that are used to destroy pests. In the agricultural industry, pesticides are classified into two categories, carcinogenic and non-carcinogenic. A carcinogenic pesticide is a substance or agent producing or inciting cancer. Conversely, a non-carcinogenic pesticide is substance that does not produce or incite cancer. Most agricultural pesticides were registered in the 1950’s, with no standard regulations. The most considerable standard prior to the amendments of the Federal Food, Drug, and Cosmetic Act (FFDCA) was, if a revocation of a pesticide occurred, would it have an impact on the prices or availability of food to the consumer....
