Effects Of Pesticides On The Environment

Some research studies show that these chemicals are also the cause of birth defects in children. With the increase in the use of these chemicals, there will be an increase in birth defects. According to research done by the University of California, pregnant mothers who live within a mile away from crops that are sprayed with pesticides are more likely to develop autism in their babies. If the use of pesticides continues to grow, one day the human race with completely diminish.

Pesticides and preservatives are not only harmful to human beings, but they are also harmful to our environment and ecosystems. Pesticides used in organic farming may run-off and contaminate nearby bodies of water. If enough contaminated run-off from pesticides and artificial fertilizers get into water, it is able to poison animals and fish that live there. According to Raloff, recent studies have demonstrated that exposure to hormones has a substantial effect on the gender and reproductive capacity of fish, throwing off the natural cycle, (1). This is not only harmful to the animals that live there, but if enough fish are dying because of poisoned run-off, the fish industry could suffer and it will affect humans as well. The same chemicals that poison bodies of water could seep into our groundwater and affect the well water we drink and use daily. This does not happen with organic farming, because no chemicals are ever sprayed on the fields and there is much more run off because of tilling practices.

To understand pesticides, we must look at the facts about them. According to the EPA, pesticides are chemicals specifically designed and sold to prevent, destroy, or repel pests from garden, greenhouses, fields, and orchards (Learn About Chemicals Around Your House). Charlotte Gerber’s article, How Do Pesticides Kill Bugs, explained that pesticides targets insects and kills them by attacking the nervous system and then when the muscles are over-stimulated, this will lead to paralysis and death. The effect of the organophosphates that cause that in pesticides was discovered in the 1930's during World War II. They were used in the creation of nerve gas, which was used in chemical warfare. When used in lethal dosages for humans, organophosphates cause extreme excitability, convulsions, paralysis and in most cases, death (Gerber). According to Effects of Pesticides on Human Health, The World Health Organization estimates that there are 3 million cases of pesticide poisoning each year and up to 220,000 deaths, primarily in developing countries (Lah and Glibert 2011). Children, and any other young and developing organisms, are particularly vulnerable to the harmful effects of pesticides. Even very low levels of exposure during development may have adverse health effects. Exposure can even lead to neurological health effects such as memory loss, loss of

This analysis of case studies from Los Alamos National Laboratory, and the case study to predict the effects of pesticides on aquatic systems and the waterfowl that uses them. Comparing the two processes of these case studies, along with analysis of the assessments. Describing the case study on the effects of pesticides in aquatic ecosystem, the risk assessment correlated to observed field studies and evaluate the importance of this type of correlation in general for all risk assessment efforts. Breaking down the ecological and social

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

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

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

Pesticides are chemicals used to kill organisms that kills crops or reduce crop quality. While pesticides give farmers some level of peace of mind, they have negative effects on their surrounding ecosystems. Pesticides do not discriminate between organisms it kills, consequently, it harms organisms that are beneficial to the environment such as bees. An essential service that bees carry out is pollination. In its search for nectar bee inadvertently fertilize female plants and as a result bees contribute to the food supply. One can

America the Beautiful! So why are we destroying it everyday with the use of pesticides? It has been proven that pesticides have affects on it's surrounding, although made to improve earths resources, they typically take there negative effect on the environment in time. Pesticides affect more than the environment; they also affect the animals and humans living in the environment. There are alternative, to this major problem but, we as the caretakers of earth must act fast. In the following paper I'm going to share with you what pesticides are. I'll tell you why they are not safe to use and some of the affects of pesticides. Last, I will talk about some new alternatives there are

It is also shown that pesticides are partly responsible for the rising cancer rates and birth defects among children (“Pesticides”).

Can there be side effects from consuming chemicals on our fruits and vegetables now or later down the road? According to an 18-month study of sperm samples from 155 men who ate fruits and veggies with pesticides on them had a 49 % lower total sperm count and 32% fewer sperm that were shaped normally. Compared that to the group of men who ate the pesticide-free produce these men had normal shaped sperm and count. The more pesticides a man had exposure to the more sperm he had that were deformed. Oaklander, (2015). To me, this looks like an example of side effects of eating chemicals on our fruits and veggies. According to the American Academy of Pediatrics, Children are especially at risk as the child's diet is the dominant source of exposure to pesticides Bauers, (2014, May 12). I have my own suspicions about how exposure to these chemicals could affect the children of this generation. I have found no sources to back this up except for my personal experience working with children. What if some of the mental, physical, and learning disabilities that the children of this generation are suffering from are from exposure to the chemicals that they are eating on their fruits and vegetables. I have noticed that when the parents of these children take them off of the conventional fruits and veggies and start having them eating the organic varieties. Some of the symptoms of their disabilities disappear, On the other hand, if they get off of the organic varieties and back onto the conventional varieties of the symptoms come back full

Environmental conditions change the way that pesticide moves and interacts with an environment. Rainfall, temperature, and wind can all move pesticides out of their target zone. These environmental factors can also impact the escape of pesticide through volatilization. Volatilization is a means of major pesticide loss and its rate of loss can often exceeds that of degradation, runoff, or leaching (van der Werf, 1996). For example, in an Oregon study, soil samples 64km from any agriculture were found to have DDT residues, and in Saskatchewan, Canada, 20% of 2, 4-D iso-octyl ester volatilized in 24 hours (Pimentel, 1995). Once in the atmosphere, pesticide residues can spread anywhere, even

  I will start by stating a crucial fact that has changes the life of nature as it was once known. “Since the mid-1940’s over 200 basic chemicals have been created for the use in killing insects, weeds, rodents, and other organisms” (Carson 43). The use of these chemicals have spread quickly. One of these chemical pesticides is dichlorodiphenyltrichloroethane, better known as DDT. DDT was first discovered in 1874 and used during WWII, to kill lice. After being used during the war it began to be used in the agricultural world as an insecticide. The problem with this was that although the agriculture industry was benefiting, it was benefitting at a cost to the environment.

Pesticides are extremely popular in modern agriculture to maintain crop health and minimize financial losses. In Asia, where agriculture is one of the main sources of income for the increasing population, pesticides are a necessity to be able to produce a crop yield year-round at a relatively low cost. Because of the low governmental regulation towards environmental policy, low quality/high toxicity pesticides are used without any regard for their effects on health and the environment. The improper usage of pesticides has contributed to the pollution of surface water, groundwater, and soil, as well posed a threat to the health of local communities. This paper describes the impact that pesticide use has on the environment in Southeast Asia, as well as the societal complications that arises with regulation. **

There are many positive effects of using pesticides and the environment is getting the direct or indirect results of pesticide application.
