Question

how can i calculate part a 

Concentrations of toxaphene in fish may impair human health and fish-eating birds (such as bald eagles) that feed on the fish. (a) If the log of the octanol-water partition coefficient (log Kow) for toxaphene is assumed to be equal to 4.21, what is the expected concentration of toxaphene in fish? (Assume that the equilibrium aqueous phase toxaphene concentration is 100 ng/L.) (b) If it is assumed that an average person drinks 2 L untreated water daily and consumes 30 g of contaminated fish, what route of exposure (drinking water or eating fish) results in the greatest risk from toxaphene in 1 year? (c) What route of exposure is greatest for a higher-risk group that is assumed to consume 100 g fish per day? Support all of your answers with calculations. Assume the following correlation applies to toxaphene and our problem's specific fish: log BCF = 0.85 * log Kow - 0.07
