Effects Of Pesticides On Environment

9. How would the soil biota be affected by using traditional chemical pesticides and would this differ from using transgenic methods? Which method would be safer and why?

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.

The purpose of this course is to provide the fundamental knowledge of the effects of environmental chemicals on living systems, and the toxic responses of the human and plant systems. Students will discuss risk, ethics, and social responsibility with regard to environmental toxicology.

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

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

The pesticide industry rose to fame in the period of World War II where numerous chemicals being used in warfare and they were found with capabilities of killing insects. Insects were being used as experiments while testing the chemicals that were being used to kill other humans. In the middle of 1940, because of the poisonous nature of some pesticides, though still effective and good played a very great role towards agriculture, the federal government managed to respond by initiating some few regulatory rules. This paper is aimed at analyzing the Environmental Protection Agency (EPA) regulations that are used in pesticides, it will also provide some threats that pesticides pose on the environment’s well-being, as well as human’s, and will

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”).

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

d)Technological analysis: the particular awareness shown the latest years for the health, and for food gardening comes also from the discovery of the many pesticides and the effect that have on us. Today, the biggest concern in the Us and worldwide seem to be a class of pesticides called organophosphates, which are designed to attack molecules in the nervous systems of insects. We have similar molecules in our bodies. http://news.discovery.com/

In this reference work by the National Institute of Environmental Health Sciences Community Outreach & Education Program, I gathered information mostly about pesticides used in conventional farming techniques. With their concentration on pesticides the EHP gave information about the different effects of pesticides on organic and conventional foods. Providing even

My third main point is against the use of pesticides is organic and biodynamic farming. Organic farming is a method of crop and livestock production that involves much more than choosing not to use pesticides, fertilizers, genetically modified organisms, antibiotics and growth hormones. Yakowski states, “Maintaining the health of the soil is a key organic principle” (16). To continue to have healthy soil farmers need to avoid the use of genetically modified organisms (GMOs). GMOs harm soil quality, disrupt ecosystems, and decrease annual crop yield potential. Yakowski states, “Animals raised on an organic farm, whether chickens or cattle, must be provided with humane living conditions, such as access to the outdoors, adequate space, grazing pastures, and organically produced feed” (17). Keeping these living conditions help the animals to reduce potential illnesses. Synthetic growth regulators, steroids, antibiotics, and hormones are not able to be used for the animals at any time. Yakowski states, “Biodynamic farming incorporates many of the methods used in organic farming. It’s not just about sustainability, but also focuses highly on regeneration of the soil” (19). Farmers use cover crops and companion planting instead of chemical controls which is way better for the environment. Biodynamic farming does not use any chemical preparations. They use things such as manure, fermented herbs such as chamomile and valerian, or minerals such as silica. The crops you obtain from
