Recommended: Effects of pesticides on agriculture

Pesticides are such types of compounds which kill pests such as insects, fungi and unwanted plants such as weeds. They are used to kill mosquitoes which are used in public health, and in to kill pests that destroys crops in agriculture. Their nature is that these pesticides are quite poisonous to different species and humans also. They must be disposed of properly and quite safely.

Pesticides are the one of those poisonous substances that is spread into the environment to kill living beings intentionally. Substances included that kill weeds (herbicides), fungus (fungicides), insects (pesticides), rodents (rodenticides), and many others. to manage such specific pest problems these usage of poisonous pesticides has become common throughout the world. Pesticides are used everywhere like in parks, buildings, schools, forests, homes and roads as well as in agricultural fields. Pesticides can be used anywhere right from the can of bug spray which is used under the sinks normally in kitchens to the crops which are speeded in acres of farmlands therefore it is too difficult to find those areas where pesticides are not being used. Other than that pesticides can be found in the air we breathe in, the water we drink and the food we have.

• Organophosphate Pesticides

Such types of pesticides affect the nervous system badly by disrupting the enzyme that regulates acetylcholine, it’s basically a compound that occurs throughout the nervous system and in which it works and functions as a neurotransmitter. Many of the organophosphates are pesticides. They were introduced in the early 19th century, but their effects on insects similarly effecting on humans, were basically introduced in 1932. Some are very poisonous (they were used in World...

5) Thin Layer Chromatography (TLC):

TLC is a quite simple and a quick procedure but an inexpensive procedure. TLC gives the chemist a quick answer as to how many parts are included in a mixture. TLC is also used to support the identity of a compound in a mixture when the Rf of a known compound (preferably both run on the same TLC plate).is compared with the Rf of a compound

6) Low Pressure Liquid Chromatography (LPLC):

Low pressure system is such a method which is used for the purification of recombinant proteins and work with those columns which are pre-packed.

7) Spectroscopy

Spectroscopy is the method which is used for the absorption as well as emitting, or scattering of radiation which are electromagnetic either qualitatively or quantitatively.The matter can be solid, liquid, gasses , atoms, molecules, atomic or molecular ions.

    What is a pesticide?A pesticide is a chemical substance used to kill pests, especially insects. A pesticide is also refered to as a biocide. Most pesticides are applied in spray form but occasionaly you will see pesticides that are in powder or pellet form. Pesticides are used on a variety of things, anything from crops like corn, barley, and wheat, to plants like petunias, marigolds, and rhodadendrons, which are usually found in small gardens greenhouses, and even in your backyard.

  • Spectroscopy Essay

    1076 Words  | 3 Pages

    Atomic Absorption (AA) Spectroscopy is a quantitative analysis technique that uses the absorption of light through a flame and gaseous chemicals. AA Spectroscopy can be used for a multitude of purposes, most notably finding the concentration of one or a few elements in a compound. AA Spectroscopy can work in two different ways using an open flame and gaseous chemicals or a graphite furnace. Flame AA Spectroscopy works by taking a compound or element and disassociating it into an aqueous solution. The solution is then blown through an incredibly small nozzle which nebulizes the liquid into a very fine mist. The nebulized liquid is then blown through a flame with a very small beam of light passing through it. This light beam detects different elements in the flame and uses the known light absorbance of the element to determine the concentration of the element in the solution. The other form of AA Spectroscopy uses a graphite furnace to heat up and incinerate a sample. A solid compound is placed in the furnace which then heats up to 2000-3000 C effectively atomizing the compound and in the process turning the rest into ash. The light beam is then shot through the furnace as the solid is being heated and subsequently atomized and the machine records the absorbance rate much like the Flame AA Spectroscopy would. The difference between flame and furnace spectroscopy is in the atomization of the sample; because the Flame Spectroscopy uses pressure to atomize the compound, much of the compound is lost when sprayed

  • The Magnificence Of Nature In The Silent Spring, By Rachel Carson

    1358 Words  | 3 Pages

    The author describes each chapter with a surreal narration. It begins with “A Fable for Tomorrow”, which starkly declares a bleak future of every U.S village if they erred to use pesticides. “The Obligation to Endure” describes the lack of public awareness and how it would become grievous. She justly reasons that if the public might suffer from long-term misfortunes due to insecticides usage, they have a right to know the facts. Felicitous “Elixirs of Death” describes the nature of insecticides in three apt words. Chemical structures of common biocides are explained in an uncomplicated fashion. A series of three successive chapters is dedicated to Earth and its components. These chapters include the closely inter-connected ecological cycles, existing in the water, mantle and soil horizons. Pesticide dispersal in soil followed by its access into the ground water table and the waterways is an inconceivable process. The book promulgates the escape of biocides from their place of application, and their integration into natural bodies. All her chapters thereafter revolve around the various short-term and long-term effects of biocides on the biosphere. Rachel Carson had stated countless dire cases wherein complete ecosystems faced annihilation. The influx of detrimental chemicals extended their reach over animals and plants, and were causing human mortalities as well. Humans are a part of

    However Spectroscopy is not a recent development, as it has been utilized for many years since Isaac Newton made the first advances in 1666. Spectroscopy is the study of light as a function of wavelength that has been emitted, reflected or scattered from a solid, liquid, or gas. Fundamentals of Spectroscopy Spectroscopy is the distribution of electromagnetic energy as a function of wavelength. Spectrum is basically white light dispersed by a prism to produce a rainbow of colours; the rainbow is the spectrum of sunlight refracted through raindrops. All objects with temperatures above absolute zero emit electromagnetic radiation by virtue of their warmth alone; this radiation is emitted at increasingly shorter wavelengths as temperature is increased.

  • Argumentative Essay On Pesticides

    864 Words  | 2 Pages

    As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should

  • Pesticides Essay

    1456 Words  | 3 Pages

    Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.
