A person (70kg) eating locally caught fish from water contaminated with 100ppb TCE and 100ppb aniline. The bioconcentration value for TCE and aniline in fish is the same at 1.06mg TCE (or aniline) per kg fish, respectively. Fish is only exposed to these contaminants in its environment. About 54g of fish is consumed in 350days/yr for 30years. Assume bioavailability value of 1. The potency factor for TCE is 1.1 × 10$# kg.day/mg and reference dose is 1.00 × 10$% mg/kg.day. Whereas the potency factor for aniline is 5.7 × 10$* kg.day/mg and reference dose (based on drinking water) is 1.60 × 10$& µg/L. Unlike aniline, TCE is not a carcinogenic compound. There are 70yrs in a lifetime and 365day/yr. a) Using chronic daily intake calculation, determine the non-cancer risk (number of people in one million) for the above case. b) Calculate the cancer risk (number of people in million) for the above case.

Lake Pekko has a pentachlorophenol (C6HCl5O) content of 42.8 μg/L, according to measurements. A lipid content of 30,600 μg/kg was found in an investigation of Matsu fish. What is this fish's bioconcentration factor (in L/kg)?
The organophosphate Azinphos-methyl has a96-hour LC50 value of 3 ppb for rainbow trout. Inan unfortunate incident, 200 g of this pesticidewas sprayed on a field, and a subsequent heavyrainfall washed 35% of it into a nearby lakehaving a surface area of 30,000 m2and anaverage depth of 0.5 m. Would the pesticideconcentration in the lake water have beensufficient to kill a significant fraction of therainbow trout in the lake?
In biological systems, buffers are important because they facilitate changes in pH to enhance biological activities of proteins and nucleic acids. True False
The glass electrode used in commercial pH meters gives an electrical response proportional to the concentration of hydrogen ion. To convert these responses to a pH reading, the electrode must be calibrated against standard solutions of known H+ concentration. Determine the weight in grams of sodium dihydrogen phosphate (NaH2PO4 · H2O; FW 138) and disodium hydrogen phosphate (Na2HPO4 ; FW 142) needed to prepare 1 L of a standard buffer at pH 7.00 with a total phosphate concentration of 0.100 M . See Problem 24 for the pKa values of phosphoric acid.
