Environmental Conditions Change The Way That Pesticide Moves And Interacts With An Environment

Excess pesticides can end up in the water supply due to runoff water or seepage through the soil.

Rain washes the pesticides that are used in our Australians households and then become run-off in drains and sewers. They then make their way into nearby water bodies, wether that be creeks, rivers or even oceans and settle within the soil by sticking to small particles, including tiny living organisms like phytoplankton (M. Barwick, 2003, pp. 471-502). Small fish consume these tiny organisms, which may then be eaten by a larger organism and this continues until the top order consumer is reached. The concentration that first began in the phytoplankton and has multiplied sufficiently as it moves along the food chain. The amount of the pesticide has reached a highly toxic level in the top order predator, whether that is birds or even humans. As a result of the biomagnification of pesticides and other chemical the marine environment and the organisms that live within it are heavily affected. The build up of heavy metals, for example, it interferes with the formation of red blood cells, creates liver and kidney implications and forms reproductive defects in many organisms. This hinders an organism’s ability to survive and reproduce and can create a decline in species

The Everglades used to be a very beautiful tourist attraction, but have been largely affected by the existence of pesticides. However, the majority of pesticides is not specifically targeting the pest only but they also affect non-target plants and animals during their application. The Effect of pesticide runoffs on the Everglades is destroying one Florida’s major tourist attractions due to the cultivation of sugar cane just to mention one of those responsible and creates a loss of natural habitat, water pollution, and threatens existence of wildlife. Many pesticides are not easily degradable; they persist in soil, leach to groundwater and surface water and contaminate wide environment.

Leaching of pesticides, herbicides and other Argo-chemicals, these chemicals are the overriding causes of agricultural pollution owing to the numbers of invasive pests, weeds, and diseases. They're highly toxic and have the potential of remaining in the environment for ages. When it rains, these chemicals will leak

Symptoms of pesticide poisoning are often deceptively misdiagnosed as flu or allergies. Other problems associated with the use of chemicals include headaches, nausea, fever, breathing difficulties, high blood pressure, and temporary paralysis. The National Academy of Sciences reports that at least one out of seven people are significantly harmed by pesticide exposure each year (American Defender Network, 1989). Unfortunately, due to the high costs of inspection, tests for pesticide poisoning are rarely performed.

It has been a prime location for studies to be conducted by health organizations to see if there are any links to the pesticide usage occurring along with people living in the vicinity of where it is being used. ARTICLE PESTICDES STUDY (Kehoe) The study correlates a link between certain chemicals that are used in the manufacturing of pesticides and these chemical ORGANOCHLORINES to Alzheimer’s disease along with many autism related defects between children. Children are who we try to keep safe as they are the young and will be our future. Pregnant women living in pesticide applied areas were more likely to have a child with birth defects as the chemicals are absorbed through the air and can reach the fetus via the bloodstream. These are also the most susceptible to these chemicals being used by farmers and the by the produce they

Pesticides are also found in the Great Lakes. These pesticides are made up of dangerous chemicals like toxaphene and chlordane. The rain transports the pesticides from crops to bodies of water like the Great Lakes. They are then absorbed by phytoplankton and it moves up the food chain from there. Pesticides

By using these chemical pesticides on the plants, it causes dissolved oxygen depletion in the water, phytotoxicity to the plants, and poisons the animals (Environmental Effects of Pesticides). From the greediness of crop cultivation, millions of species of fish will disappear. These pesticides do not only get into the ocean by spraying it, they get into the ocean when small particles fly over from the drift of the wind. This is especially common at beaches where people spray chemicals on the grasses nearby to prevent other people from being bitten by insects. Not only do pesticides affect the oceans, but the plants as well. These pesticides cause phytotoxicity refers to plant injury. By using these chemical pesticides, it damages the plants, especially those genetically similar to weeds. They can progressively result in mutations little by little until eventually there will be a period of time where the plants now will be very different. Even though this is what is happening now, Hawthorne, an author from 200 years ago, also thought that scientists were being evil. In “Rappaccini’s Daughter,” when it states “Dost thou deem it misery to be endowed with marvellous gifts, which no power nor strength could avail an enemy?...Wouldst thou, then, have preferred the

This suggests that the roadsides was once beautiful and bloomed with healthy and lively vegetation; however, they are now destroyed due to the use of pesticides. From these examples, it can be shown that even though pesticide is beneficial, its deadly effects outweigh its benefits; in addition, it is a dangerous substances to the environment, organisms, and even human.

The chemical pesticides used in farming affect the quality of water because of run off which then go into lakes or rivers. In chapter four, Carson concentrates on the water pollution caused by pesticides. The pollution can be unsafe for use and causes fish to die. An example used is a study done by the United States Fish and Wildlife Service in 1960 that showed that “our waters have become almost universally contaminated with insecticides.” (pg.41) The pesticides are especially threatening to groundwater which is an important source of drinking water for humans. Consequently, the chemicals in pesticides can cause cancer and other harm effects on our health. Another issue is that the pesticides in water and can mix with other chemicals and become a new chemical. Therefore, it can lead to the creation of an unknown chemical with harmful

"It is not possible to add pesticides to water anywhere without threatening the purity of water everywhere. Seldom if ever does Nature operate in closed and separate compartments, and she has not done so in distributing the earth's water supply" (Carson 42).

Everyday pesticides are dumped into our environment. Over time most of the pesticides make thier way to a source of water, whether it's groundwater or a body of water. According to Lewis Regenstein author of "America the Poisoned" two thirds of the nation's lakes have serious pollution problems. 80% of 3,700 urban lakes in the United States are destroyed. More than 94 million residents could use these lakes for recreational use or for a source of water (169). Cincinnati's drinking water contains about 700 chemicals. 90% of them did not exist 20 years ago. The main sources of most of these chemical pollutants are municipal sewage, industrial discharges, and runoffs from farming areas. There are also several other chemicals in America's drinking water. Although hazardous, there are approximately 60 chemicals that are mixed into water in the process of treating it. Unlike rivers or lakes, underground supplies are not processed at treatment plants before being used by humans. "More than one hundred million of our citizens depend in a whole or in part on underground as sources of drinking water (Beck qtd. in Regenstein 172). Once groundwater becomes contaminated, there is usually no way to clean it.

The chemicals that are sprayed on the ground, even household weed killers, have a tendency to wash into local streams and rivers with the first rain. This has caused many incidents of fish, numerous miles down a river, to be found dead due to the toxins in the water. Carson states that the best way to eliminate a pest problem is to use natural predators, which are non-toxic, and a better long-term solution then pesticides, since many pests will become immune to most chemicals.

Fruitvale’s water supply has and had been contaminated by the no bug pesticide released into the earth years past, but it’s only a matter of time before the contamination reaches Fruitvale’s municipal water well. The pesticide was proven to be the cause of the contamination. It does not decompose as expected in the ocean and soil. To make matters worse, it is still located in the very ground we are standing on right now. If we continue to ignore this existing problem, the no bug pesticide will sure enough contaminate our own water that we drink in a matter of years and is likely to make us sick. It already has with 4.9 ppb of the pesticide located in the lawns with 5 ppb being the maximum amount before it is illegal and not drinkable. Of the multiple options, option A would be the

One concern about pesticides and herbicide usage is the amount of residues left on the end product of crops sprayed with the chemicals, and their effects on human health. (Williamson, 2007, p. 184). However, these effects are closely tested and levels are strictly regulated to ensure there is no danger from possible pesticide residues. Since 1910, many rules, regulations, and agencies have been formed to monitor the safety of the pesticides and herbicides used in conventional farming. These chemicals must meet specific safety standards in order to be registered for use, and regulations on levels of each product safe for use are also put in place. (Tafel et al.,2007, p.184). All pesticides are rigorously examined to ensure they have no significant effects on human health, or the environment. The residues in the food chain are closely monitored, and regularly tested, to ensure they are below legal limits. In a recent survey of residues
