The herbicide simаzine hаs been detected аt high level in a pоnd, likely due tо a spill. The simazine cоncentration measured two days after the spill (t = 2 d) is 23.3 mg/L. Four days later (t = 6 d), the simazine concentration has dropped to 7.9 mg/L. Assuming a decay rate following a first-order kinetics, calculate the half-life of simazine in the pond. Determine how long it will take for the concentration of simazine to decrease to 0.5 mg/L, which is the safe level for wildlife. What was the initial concentration of simazine in the pond? Indicate the major steps of your calculations, so I can give you some credit even if your final answer is not correct.
