Human Price

Page history last edited by Michael 13 years, 6 months ago
 
The Human Price (chapter 12)
  1. Humans used insecticides
  2. The pesticides were the human fault
  3. Pesticides affected the humans as well
  4. Those exposed are affected
  5. This chapter is about the affect of public health. These pesticides affect not only animals, but people also. Most people use to worry about small pox and other diseases. Now the people are worrying about the diseases you can get from the DDT.
  6. effects of pesticides, insecticides, and other chemicals on human beings
    7. Exposure to chemicals can cuase acute poisoning.

    8. Storage of chlorinated hydrocarbons group in the fatty tissues and affect the whole body.

    9. Fat-soluble insecticides get stored in cells, which cause interference with vital and necessary functions of oxidation and energy production.

    10. Chlorinated hydrocarbon insecticides affect the liver, leading it to be defenseless against the poisons hat enter it.

    11. Organic insecticides affect the central nervous system causing abnormal sensations, tremors, convulsions, memory loss, insomnia, and depression.

    12. Acute poisoning of DDT causes tiredness, paralysis, heaviness, limb aching, mental incompetence, and joint pains.

    13. Methoxychlor damages the kidneys and has long-lasting effects damage or the nervous system.

    14. Dieldrin causes memory loss, insomnia, and nightmares to mania.

    15. Lindane causes negative effects on the central nervous system.

    16. Ginger paralysis was from triorthocresyt phosphate which caused paralysis.

    17 Malathion causes severe muscle weakness and the destruction of sheaths of sciatic and spinal nerves.

    18. There are many human health aspects described in this chapter. The liver, kidneys, central nervous system, and skin tissue of the body are explained to be affected by numerous types of chemicals, pesticides, and insecticides. Many people that have been in contact with these chemicals may experience many side-effects and develop new disease that may lead them to never fully recovering or even death.

Acute toxicity of a pesticide refers to the effects from a single exposure or repeated exposure over a short time, such as an accident during mixing or applying pesticides. Various signs and symptoms are associated with acute poisonings. -http://ianrpubs.unl.edu/pesticides/ec2505.htm#pt

 

  • Examples of chronic poisoning effects
  • Carcinogenicity--ability to produce cancer or to assist carcinogenic chemicals.
  • Mutagenicity--ability to cause genetic changes.
  • Teratogenicity--ability to cause birth defects.
  • Oncogenicity--ability to induce tumor growth (not necessarily cancers).
  • Liver damage--death of liver cells, jaundice (yellowing of the skin), fibrosis and cirrhosis.
  • Reproductive disorders--such as reduced sperm count, sterility, and miscarriage.
  • Nerve damage--including accumulative effects on cholinesterase depression associated with organophosphate insecticides.
  • Allergenic sensitization--development of allergies to pesticides or chemicals used in formulation of pesticides

  • Pesticide exposure can cause both short-term (acute) and long-term (chronic) health problems for animals and humans. Studies have shown strong associations between chemical pesticides and health problems, including fertility problems, birth defects, brain tumors, breast cancer, prostate cancer, brain cancer, childhood leukemia, non-Hodgkin's lymphoma. Children and young animals are especially vulnerable to the toxic effects of pesticides. Their bodies, brains, nervous, immune and reproductive systems are developing and their detoxification systems are either immature or not yet functional.

    The World Health Organization estimates that 200,000 people are killed worldwide each year as a direct result of pesticide poisoning. In 1990, that number was 30,000. They also estimate that 3 million people are poisoned each year, a large number of them are children. A study in England and Wales showed that 50% of pesticide poisoning involved children under the age of http://www.veganpeace.com/organic/Pictures/pesticides

     

    There are many types of synthetic pesticides. The main classes consist of carbamates, organophosphates , organochlorines and pyrethroids. Carbamates and organophosphates affect the central nervous system. Organochlorines affect the reproductive, nervous, endocrine and immune system. The effects of pyrethroids are still unclear. Increasingly more insects and plants are becoming resistant to certain types of pesticides. Because of these so called superbugs and superweeds, farmers have to either increase the amount of pesticides they apply or use more toxic pesticides.

    Regular farmers rely heavily on synthetic pesticides. The chemicals these pesticides contain are dangerous to the environment and to our health. They destroy wildlife, pose risks to the people that apply them as well as bystanders and leave chemical residues in our food.

    Pesticides which are sprayed can become airborne and eventually end up in soil or water. Pesticides that are applied directly to the soil can be washed off into water or can percolate through the soil into the groundwater, a major source of our drinking water. These pesticides are broken down or degraded by the action of sunlight, water, other chemicals or microorganisms. This degradation process often leads to the formation of less harmful residue, but can sometimes produce more toxic products. It is also possible for a pesticide to become resistant to degradation by any means and therefore remain unchanged in the environment for long periods of time. These are called persistent pesticides.

    The properties of a pesticide determine its behavior. Pesticides that evaporate easily have the greatest potential to go into the atmosphere. Pesticides that are very soluble in water will seep easily through the soil and are potential groundwater contaminants. They also tend to stay in the water longer and harm fish and other organisms. Pesticides that are insoluble in water usually stick to the soil and settle to the bottoms of bodies of water.

    Pesticides can be stored in living organisms and accumulate over time. The levels of a pesticide which accumulates in a fish for instance can be hundreds of thousands of times greater than the level of the pesticide in the water where the animal lives. This type of accumulation is called bioaccumulation. The higher a given species is on the food chain, the greater it is at risk to be harmed by pesticides. An example of this problem is the population decline of fish-eating birds by both reproductive failure and the thinning of the eggshells as a result of organochlorine pesticides. Humans which eat animal-based food are also at risk to be exposed to bioaccumulated pesticides.
