Atrazine

Part one: My group did Atrazine and I came to quickly discover that it wasn’t just an herbicide farmer’s used. There was so much more to the story and it was more than a controversial topic, it involved a major feud between two sides. The company Syngenta, who primarily produces atrazine, and a now well-known scientist, Dr. Hayes. With Syngenta being the primary producer of the product it’s a no brainer that they would suffer if it were to be taken off the market. Dr. Hayes has published research

Stueve, T., and Gallipeau, S. 2010. Atrazine induces complete feminization and chemical castration in male African clawed frogs (Xenopus laevis). Proceedings of the National Academy of Sciences 107: 4612-4617. The authors have assigned key words described throughout this article including amphibian decline, endocrine disruption, pesticide and sex reversal. The larger or global context for the research conducted in this article is that the pesticide Atrazine is widely utilized across the entire

Atrazine is one of the most widely use herbicides in the United States since it was discovered in 1958. Atrazine plays a significant role in food production in the US and in feeding countries around the world, but it’s also been linked to negative health outcomes and the chemical persists in the environment for a long time. Atrazine is a commonly detected pesticide in drinking water and has caused widespread water contamination in Europe. The water-borne herbicide in contaminated drinking water has

Atrazine is a herbicide of the triazene class. It is used to prevent pre and postemergence broadleaf weeds in crops such as maize and sugarcane and on turf, such as golf courses and residential lawns. Also, made in a lab and not naturally. How is Atrazine used? It is sprayed on plants, grass, and weeds. Why is it used? It is used to kill weeds and unwanted plants that are in places people don’t want them to be. Also, used heavily by farmers on crops. What happens when it enters the environment

Schneider-Paolantonio, focused on Ecology and the effects of human interference on the environment and its organisms. During recitation, we examined the effects of atrazine, a pesticide, on African clawed frog populations. Atrazine is the most commonly dispersed pesticide in the world, and contaminate ground and surface water that spreads through other habitats. Atrazine caused the genetically male frogs to become demasculinized and to mature as feminized adults. While their chromosomes (ZZ) stayed the same, their

water source contaminated with Atrazine from a run off site and soil contamination. According to the EPA “The Maximum Contamination Level Goal for atrazine is 0.003 mg/L or 3 ppb” (Agency, Basic Information about Atrazine in Drinking Water, 2013). However, individual states are allowed to enforce more stringent guidelines. People who drink water that has been contaminated with high amounts of Atrazine can develop cardiovascular and reproduction problems. “Atrazine has been shown to cause changes

herbicides that can be harmful to soil and agriculture farms. For example, Atrazine – a weed killer managed on agricultural farms – has been used since 1959. This weed killer gets sprayed over corn fields or soybean fields and then “it poisons from within” (Steingraber pg. 157). Atrazine can also inhibit the growth of nearby prairie groups when ingested, or we could look at the study done on lab rats that show when atrazine is exposed at an early age, it modifies the development of the mammary glands

creation of tumors, it has also been correlated with breast cancer in female farm workers. In the other hand, leukemia has been correlated to three different pesticides – atrazine, 2,4-dichlorophenoxyacetic acid and captan (Berry et al. 2012). Also, particularly in African American males, there is a correlation between atrazine or captan with prostate cancer. Unfortunately, there is more research on the effect of pesticides and cancer on farm owners than on farmworkers (Zham et al. 1993). However

In the United States, starting from the first breast cancer case in 1930s to today, a woman's lifetime risk of breast cancer increases to one eighth (Gray et al.). Continuously increasing breast cancer rate has caused a lot of concerns among not only ordinary people but also scientists. For decades, scientists have been working on the causes of breast cancer in order to find the corresponding methods of treatment. However, only about 25% of the breast cancer cases got explained (Brody et al.); till
