Essay on The Use of Imidazolinone Herbicides in Rice Fields

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

What has been brought to light in recent years is the effects of these chemicals on the body’s immune response. By introducing these toxic chemicals into the body, the potency of the immune system is compromised. More commonly than not, the body’s magnificent defense system will kick in and destroy foreign invaders but all it can take is an overwhelming amount of chemicals to slow or even shut down the body’s response systems. A large amount of these types of chemicals introduced into the body at one time would be considered acute toxicity and could even cause death. Additionally, a small amount of these poisonous substances brought into the body over a long period would be considered chronic toxicity and can have detrimental effects on the body’s natural response (Hoernschemeyer 55-57). This information is startling enough to want to make a change from conventionally grown food to pesticide-free organic

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

Conduct studies on food, air, water and soil to determine how they are altered when coming into contact with medicines, garden chemicals and industrial chemicals

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

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

This article talks about what a pesticide is and how it affects people. This is relevant to my research topic because I will be using pesticides on plants to measure the growth. In order to do this, I will need to know what a pesticide is and what it does. A unique feature of this article is that it includes videos explaining the topic, and links at the bottom of the page to look further into pesticides. A strength is that the article is very specific and on-point. However, it doesn't show much more than just what a pesticide is. There is no bias in this source.

The purpose of this article is to explain an investigation attempting to correlate negative behavioral effects observed in adult male fighting fish, Betta splendens, with exposure to waterborne phytoestrogens. The phytoestrogens the B. splendens were exposed to were genistein, equol, β-sitosterol, and 17 β-estradiol. Behavioral effects of exposure were analyzed by monitoring spontaneous swimming movements, amount of time it took to react to an alleged intruder, amount of aggression toward that alleged intruder, likelihood of building a nest whilst among a female B. splendens and the area of said nest. This study was conducted given there has been no research done on the behavioral biomarkers resulting from waterborne phytoestrogens as an environmental contaminant to aquatic species, even though these animals are the highest probability of experiencing phytoestrogen exposure in their natural habitats. Additionally, when considering phytoestrogens’ ability to cause reproductive and developmental malfunction in fishes, waterborne phytoestrogen’s presence in sewage treatment plants’ liquid waste, runoff from agricultural areas utilizing manure and wood pulp mills ' liquid waste is concerning.

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

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

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.

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

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
