An 84 kg University of Toledo groundskeeper who is spraying a 100 mg/L solution of the insecticide dieldrin (MW = 381; logP = 4.56) on some trees exposes 100 cm“ of his skin to the solution over a 4 hr period. Dieldrin has a half-life of about 6 months, a volume of distribution of about 40 L/kg, and a dermal permeability of about 3 x 10° cm/sec. (a) Estimate the absorption rate during the exposure period assuming the blood concentration is much lower than the skin concentration (i.e., take the blood level to be zero in the skin absorption equation). (b) Estimate how it takes after exposure begins for the groundskeeper's plasma dieldrin levels to reach 1 ng/L. (c) Estimate the maximum plasma dieldrin concentration in ng/L that will occur in this groundskeeper due to this exposure. (d) Estimate how long it will take after exposure ends for the groundskeeper's plasma dieldrin levels to drop back down to 1 ng/L. %3Darrow_forwardWhat is the Ksp of Zn3(PO4)2 (MW = 320.8 g/mol) if its solubility in water at 25 °C is 4.9 x 10-5 g/L? format for the scientifc notation 1.0 x 10^-1arrow_forward
- An environmental chemist working for the Environmental Protection Agency (EPA) was directed to collect razor clams from a heavily-contaminated river superfund site and analyze them for their Ca+ content using graphite furnace atomic absorption spectrometry (GFAAS). The chemist dried the clams at 95 °C overnight and ground them in a scientific blender, resulting in approximately 50 g of homogenized dry weight. A representative 91.79 mg sample was taken from the approximately 50 g of dry material and dissolved in 100.0 ml. of 0.1 M HCI to create a sample solution. Using the method of standard additions, the chemist prepared five standard solutions in 100.0 ml volumetric flasks, cach containing 5.00 ml. aliquots of the sample solution. Varying amounts of a 85.0 ppb (ug/L) Cd+ standard were added to each of the flasks, which were then brought to volume with 0.1 M HCI. The Cd content of the solutions was then analyzed using GFAAS, resulting in the absorbance data given in the table.

It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu.
