Captan And Methoxychlor

In our rapidly growing world, human populations have sky rocketed within the past two generations. It is because of this that food must be harvested and provide sufficient nutrients at an unnatural rate. This is where modern science has stepped in, allowing farmers and agricultural workers to reliably yield a successful crop season. The spray on pesticides that eliminate any threat of unwanted parasites, insects, or other organisms that may inhibit the growth of the crops are a product of chemistry combined with agriculture. Two pesticides that are commonly found are captan and methoxychlor. Captan is used for a couple various circumstances, but is primarily used in the protection of fruits and vegetables from insects, rats, and will even help
As for methoxychlor, the US EPA has restricted its uses because of its toxicity. Originally used as a pesticide, methoxychlor had been researched and found to be detrimental to aquatic life, especially because of its ability to travel long distances. For this reason, monitoring pesticide levels in runoff and aquatic ecosystems is important to ensure their health. Captan is classed as a Group 2B carcinogenic, which means exposure can possibly lead to cancer. It has also been seen to cause dermatitis and conjunctivitis in humans. Ingestion of captan can cause vomiting and diarrhea. External exposure can cause irritation. Exposure to methoxychlor has been known to have hindering effects on the reproductive system, largely due to the estrogenic effects. Individuals who encounter this pesticide can come into contact in several different ways, which include, soil, water,
Everest. It was very surprising that we found such high levels of captan and methoxychlor. It has been hypothesized that these pesticides got there because of wind currents from china blew particles into the clouds, which eventually disposed of the pesticides when coming into contact with the peak. The environmental effects that captan has have been analyzed closely and concluded with the following: Trout, Salmon, and other fish similar have a very low tolerance for captan, rated at 56 ppb where as for fish such as blue gill (found virtually everywhere) their tolerance was over double, registering at 141 ppb. Fish are highly sensitive to this substance, and if exposed for three days or more, death will ensue. Captan does have a good half-life ranging between 2-10 days in most soils. The plants that it is sprayed on are able to retain much more, after two days of exposure leaf surfaces showed 800-ppm, 450-ppm after 13 days, 150-ppm after a month, and at 40 days was below the readable level2. These two pesticides are very bad for aquatic species and should be carefully applied. Their ability to travel in winds to very far places adds to the danger of their use, as without a stable aquatic ecosystem, the world would not be nearly as
