Academic Papers: Pesticide Essay

The newer organophosphate pesticides that to a degree have replaced organochlorines, such as parathion and TEPP (tetraethyl pyrophosphate), are less persistent so they do not accumulate in food chains.

Sample essay on advantages and disadvantages of pesticide …

In conclusion, pesticides do as much harm as good, so we need to find alternative solutions for the control of pests, such as orgnic growth of crops or the production of pesticides with less consequences for human health and the environment. Also countries should have a stonger regulation for the use of pesticides, so that they control the consequences for human health, and the environment of pesticides and the quantity of pesticide use in each crop.

Organic And Pesticide Essays 1 - 30 Anti Essays

Even if the organic food you're eating is from a farm which uses little to no pesticides at all, there is another problem: getting rid of pesticides doesn't mean your food is free from harmful things. Between 1990 and 2001, over 10,000 people fell ill due to foods contaminated with pathogens like E. coli, and many have organic foods to blame. That's because organic foods tend to have higher levels of potential pathogens. One study, for example, found E. coli in produce from almost 10% of organic farms samples, but only 2% of conventional ones. The same study also found Salmonella only in samples from organic farms, though at a low prevalence rate. The reason for the higher pathogen prevalence is likely due to the use of manure instead of artificial fertilizers, as many pathogens are spread through fecal contamination. Conventional farms often use manure, too, but they use irradiation and a full array of non-organic anti-microbial agents as well, and without those, organic foods run a higher risk of containing something that will make a person sick.

What makes organic farming different, then? It's not the use of pesticides, it's the origin of the pesticides used. Organic pesticides are those that are derived from natural sources and processed lightly if at all before use. This is different than the current pesticides used by conventional agriculture, which are generally synthetic. It has been assumed for years that pesticides that occur naturally (in certain plants, for example) are somehow better for us and the environment than those that have been created by man. As more research is done into their toxicity, however, this simply isn't true, either. Many natural pesticides have been found to be potential - or serious - health risks.

Pesticides - Essay by - Anti Essays

The Environmental Research Center of the University of California, Davis, worked with the agriculture community to develop activities to verify the accuracy of bioassays used by the state government to monitor farmworkers for pesticide toxicity. The university researchers discovered that the commercial bioassays in use were very inaccurate, often underestimating the level of acetylcholinesterase by as much as 40% (Matsumura F, personal communication). Furthermore, the various assays used to assess the degree of pesticide poisoning in various municipalities employed completely different units of measurement, making meaningful comparisons difficult. By working with the state regulatory agency, a new, more reliable test was developed and deployed to bring the fulfillment of the legal requirement in line with the public health intent of the law ().

Finally, China’s State Environmental Protection Administration (SEPA) estimated that use of contaminated water, excess fertilizer, solid waste, pesticides, and other pollutants has damaged about 10% (12.3 million hectares) of China’s arable land (; ). Because only about 13% of China’s land area is suitable for farming, pollution damage combined with loss of arable land due to industrial use and urbanization are endangering China’s food security. Also, China’s growing livestock-farming industry produces 2.7 billion tons of waste annually (). About 97% of the 20,000 medium- to large-sized livestock farms do not have waste treatment facilities, so waste is discharged directly into the environment, polluting the air, water, and soil ().

Some specific examples of the environmental challenges facing China include indoor and outdoor air pollution; contamination of land from use of water that contains industrial waste, untreated human and animal sewage, and excessive use of fertilizers and pesticides; deforestation; loss of agricultural land; and sustainability. The has estimated that 20 of the 30 cities with the most polluted air are in China and that outdoor air pollution from industrial, vehicular, and energy-generating sources causes 350,000–400,000 deaths each year. Water pollution results from unregulated industrial growth, rapid expansion of urban areas with insufficient infrastructure for water treatment, intense use of fertilizers, and irrigation of farmland with water containing untreated sewage and industrial waste. The also estimated that 60,000 people each year die prematurely from waterborne infectious diseases. The Chinese Academy of Agricultural Sciences has estimated that pesticide exposure affects the health of 100,000 people annually (), and this may be a significant underestimation of the actual exposure, because approximately one-half of the fruits and vegetables tested from two provinces had levels of carbamate and organophosphate pesticides in excess of government standards [; ]. Such pesticide exposures are reported to have caused reproductive abnormalities among male farmworkers (, ). Furthermore, an estimated 12 million tons of grain are contaminated annually with heavy metals, at a cost to the country of US $2.5 billion ().

Pesticide use cause and effect essay

Yes, organic farming practices use less synthetic pesticides which have been found to be ecologically damaging. But factory organic farms use their own barrage of chemicals that are still ecologically damaging, and refuse to endorse technologies that might reduce or eliminate the use of these all together. Take, for example, organic farming's adamant stance against genetically modified organisms (GMOs).

Pesticide essay. 5 types of essays

So was I, when I first learned this from a guy I was dating. His family owns a farm in rural Ohio. He was grumbling about how everyone praised the local organic farms for being so environmentally-conscientious, even though they sprayed their crops with pesticides all the time while his family farm got no credit for being pesticide-free (they're not organic because they use a non-organic herbicide once a year). I didn't believe him at first, so I looked into it: turns out that there are over 20 chemicals commonly used in the growing and processing of organic crops that are approved by the US Organic Standards. And, shockingly, the actual volume usage of pesticides on organic farms is not recorded by the government. Why the government isn't keeping watch on organic pesticide and fungicide use is a damn good question, especially considering that many organic pesticides that are also used by conventional farmers are used more intensively than synthetic ones due to their lower levels of effectiveness. According to the , the top two organic fungicides, copper and sulfur, were used at a rate of 4 and 34 pounds per acre in 1971 . In contrast, the synthetic fungicides only required a rate of 1.6 lbs per acre, less than half the amount of the organic alternatives.
