 | This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |

Risks of Urban Fishing
Article body edit
Pollution in urban waterways produces a risk for fishers when their purpose for fishing is consumption.[1] Throughout multiple rivers in the United States, carcinogens and hazardous chemicals such as mercury, dieldrin, and polychlorinated biphenyls have been found in native fish populations including the striped bass and the longnose gar.[2] Due to the chemical composure of PCBs, it takes years to breakdown and particles persist in the food chain long after their initial introduction into the ecosystem. Heavy consumption of the affected fish over the span of many years can lead to fertility issues and pregnancy abnormalities.[3] While the Clean Water Act has led to improved efforts to regulate contaminants in waterways, the water must have a recognized purpose for mandatory testing.[4] Some of the challenges presented by pollutants entering aquatic ecosystems can be lessened by finding an alternative to or limiting the use of pesticides that can enter an ecosystem through run-off and finding alternatives to reduce the amount of single use plastics that can pose hazards to aquatic life.[5]
