Question - Chlordecone is a persistent organic pollutant that was used as an insecticide. Lake Carvin is a lake in the mountainous area of Virginia that is stocked with recreational fish such as blue gill and trout. An industrial facility on the lakeshore developed an undetected leak that resulted in chlordecone being dumped into the lake at a rate of 0.5 tonnes per day. Lake Carvin's volume is 1.2 x 10⁷ m³ and the average water inflow is 7.8 x 10⁴ m³ d^-1. Assume that 15% of the water in the lake is lost to evaporation and the remaining 85% is lost as outflow.

Question -

1) What is the steady state pollution concentration? Show your work for all steps in your calculation.

2) The LD₅₀ of chlordecone for trout and blue gill fish is 0.022 to 0.095 ppm, respectively. Would you expect a fish kill to take place in this lake? Why or why not? What effects may this have on the ecosystem?
