An environmental scientist studying mercury levels in Floridas wetlands finds that mercury concentration in fish increases by 15% each year due to bioaccumulation. If the initial concentration is 0.2 ppm, after how many full years will the concentration exceed 1.0 ppm?

**How Mercury in Florida’s Wetlands Is Creeping into Fish—and Why It Matters** Recent findings from an environmental scientist studying mercury levels in Florida’s wetlands reveal a steady rise in contamination: fish are absorbing mercury at 15% more each year due to bioaccumulation. This trend is stirring attention across the U.S., particularly among communities dependent on local fish for food, conservation advocates, and public health researchers. As urban expansion and climate shifts reshape ecosystems, understanding how pollutants like mercury build up in aquatic food chains becomes critical for protecting both wildlife and human health. Multiple studies confirm that even low environmental concentrations of mercury can magnify significantly as it moves up the food chain. Unlike some pollutants that dissipate, mercury persists and accumulates—especially in predatory fish—posing subtle but ongoing risks. The scientist’s recent analysis shows that with an initial mercury concentration of 0.2 ppm, annual increases of 15% push levels well past the 1.0 ppm threshold within just a decade. This pattern underscores a growing concern about long-term exposure and ecosystem stability. **How Mercury Accumulates: The Science Behind the Numbers**
