Pesticide residues in livestock generally accumulate by two ways. Either pesticides are applied to animals through insecticide-impregnated ear tag, spray, self treatment back rubber, dust bags, injectable or through pesticides spray on agricultural crops and fodder (Poppenga, 1999). Pesticide use has a positive and dramatic effect on agricultural production through protection of crops against insects, pests and diseases (Kaeew et al., 1996). Also for all pesticides to be effective against the pests, they must be biologically active, or toxic. Because pesticides are toxic, they are also potentially hazardous to humans, fauna, animals and environment in general (Vega et al., 2005). At the same time, the livestock reared on pesticides contaminated soils, crops, and fodders may accumulate considerable residues in edible tissues. For example the accumulation of dieldrin residues in sheep from ingestion of contaminated soils was studied and it was concluded that dieldrin concentration in the fats of sheep that consume dieldrin contaminated soil fall within 10 days of removal from the source of contamination. However, dieldrin accumulates in the wool of sheep that consume dieldrin contaminated soils (Paton and Petterson, 1997).
In Pakistan, pesticides are pre-dominantly used in the provinces of Punjab and Sindh. Some pesticides are biodegradable while others persist in the soils for longer times (Tariq et al., 2006). Pesticide residues have been detected in the vegetables in Karachi (Perveen et al., 2005), in fruits and vegetable in Islamabad (Tahir et al., 2001) and in various tissues of fish in the local lakes (Saqib et al., 2005). Futhermore, pesticide residues also accumulate on cropland soil (Jabbar et al., 1993). Animals can accumulate these substances from contaminated feed and water. Also, due to the lipophilic nature of these pesticides, milk and other fat-rich substances are the key items for their accumulation (John et al.

- Seven percent of all the people involved in agriculture suffer from pesticide poisoning each year. Floristry depends on the use of pesticides to kill and control pests. The floriculture industry grows constantly, all the while, poisoning their workers by relying heavily on pesticides. Harming human health is not the only thing pesticides do. The use of pesticides also harms the environment. Neurological disorders, cancer, reproductive problems, pesticide poisoning and the loss of some animal species are some of the main problems associated with the use of pesticides....

- The Destructive Use of Pesticides in Agriculture When I was a child, I can remember my parents taking me into the apple orchard and picking apples. I couldn't wait to eat them until I got home, so I would have one for a snack right in the middle of the field. Today, when I take my children apple picking, I cannot let the children eat an apple out of fear of what pesticides could be on the apple and the harmful affects they can cause. Instead I have to take them home and scrub them before they can even take a bite.... [tags: Papers]

- The Use of Fertilisers and Pesticides in Agriculture Agriculture today dominates the majority of all land uses. As a result it has a fundamental role in maintaining the countryside and protecting the environment. The development of the use of fertilisers and pesticides has dramatically increased the efficiency of food production and has in fact more than quadrupled food production in the last century. They also have reduced the cost and increased the variety of foods available.... [tags: Papers]

- ... (2012). Physics and Chemistry: Encyclopedia of Earth. Acetylcholine (ACh) is one of the most prevalent neurotransmitters found within an animal's nervous system. It functions in both the peripheral and central nervous systems and is highly active in the somatic nervous system as well. ACh can elicit an inhibitory effect of lowering the heart rate but primarily behaves in an excitatory manner, contracting skeletal muscle. Disruptions or inadequate production of ACh have shown to be associated with dementia and irregular sleep rhythms.⁵ Looking more closely at the biology, acetylcholine is released by a neuron which then diffuses across the synaptic cleft, or gap between neurons, and bi...

- Vertical Farming - Turning Agriculture Upside-Down Food is one of the essentials of life, it is not something that we can choose to eat or not; but rather something we need in order to produce energy and survive. Not only is food essential but also sparse. Until the introduction of large scale agriculture food was something which people needed to forage and hunt. Lack of food has been a source for wars, famine, and starvation; all things we as human beings should strive to avoid. Here are some facts about what to expect by 2050.... [tags: Agriculture]

- Life is easy for the modern persons. The threat of starvation is not imminent. The days of hunting and gathering are over for the vast majority of citizens thriving in developed nations. If one is hungry they need only go to one of the many supermarkets to purchase food. The day to day has been simplified in so many ways that it is not hard to understand why the base step to that simplicity would be overlooked. Why question a good thing. Why should the public know what their food consists of. With the microwave dinners, pre-cooked deli meals, and the myriad of other processed foods many simply do not take the time to start from the bottom up with their edibles.... [tags: Health ]

- Effects of Corn Monoculture on Soils: Models for Change in American Agriculture According to writer and environmentalist Vandana Shiva, "the crucial characteristic of monocultures is that they do not merely displace alternatives, they destroy their own basis"(1993, p.50). If the self-destruction of a monoculture is really so simple, it seems that continuous cropping agriculture should long have been abandoned for a more suitable method. Unfortunately, the problem is far more complex. This paper will focus on the effects of corn monoculture on soils in general, the development of the monoculture in the United States and the effects this had on soil in this country....

- Effects of Agriculture on the Environment Introduction: Agriculture has changed dramatically, especially since the end of World War II. Food and fibre productivity rose due to new technologies, mechanization, increased chemical use, specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre. Humans, like all other species, exploit their surroundings for the resources they need to survive.... [tags: Agricultural Environment Nature Essays]

- Pesticides: What are they. Pesticides are chemicals that are used to destroy pests. In the agricultural industry, pesticides are classified into two categories, carcinogenic and non-carcinogenic. A carcinogenic pesticide is a substance or agent producing or inciting cancer. Conversely, a non-carcinogenic pesticide is substance that does not produce or incite cancer. Most agricultural pesticides were registered in the 1950’s, with no standard regulations. The most considerable standard prior to the amendments of the Federal Food, Drug, and Cosmetic Act (FFDCA) was, if a revocation of a pesticide occurred, would it have an impact on the prices or availability of food to the consumer....
