10) You are hired as a consulting engineer to a small chemical plant. The plant needs to produce 10,000 liters per day of a liquid with a maximum contaminant concentration of 100 mg/l. There are four suppliers of liquid that can be mixed together to produce the final fluid. Each source sells liquid at a different cost and with different contaminant concentrations. Each supplier has a maximum volume that can be supplied per day. You need to determine how much...

Question #1 (from Mihelcic). Assume an adult female who weighs 50 kg drinks 2 L of water every day and the absorption factor for the chemical of concern is 75 percent. The concentration of the chemical in the drinking water is 55 ppb. Determine the dose in mg/kg-day. Question #2 (from Mihelcic). Determine if exposure by oral ingestion to the chemicals xylene, toluene, arsenic, and hexavalent chromium poses a noncarcinogenic health risk. The chemical-specific reference doses (mg/kg-day) obtained from IRIS...

A regional STP handles wastewater from 22,000 people where the per capita flow is assumed to be 380 L/person/day. This STP comprises (in series) a primary settler, a trickling filter, two facultative ponds, and a mature constructed wetland. The table below gives typical values (all in mg/L) for the overflow stream after the primary settler (APS) and for the final treated effluent (FTE). Parameter APS FTE Suspended solids 120 2 Biochemical oxygen demand 130 3 Total nitrogen (as N) 30...

Post-op Pain Management: Day of Surgery (1/2) History of Present Problem: Sheila Dalton is a 52-ver-old woman who has a history of chronic low back pain and COPD. She had a posterior spinal fusion of L4S1 today. She had an estimated blood loss (EBL) 675 ml during surgery and received 2500 mL of Lactated Ringers (LR) Paimis currently controlled at 2 10 and increases with movement. She was started on a hydromorphone patient-controlled analgesia (PCA) with IV bolus dose of...

Lab 8: Exercises EXERCISE 8.1 GM is a 20 y/o male who was admitted to the ICU for severe closed head injury and multiple fractures resulting from a fighting engagement at the bar on his birthday. According to his friends, his Ht is 178 cm. His measured Wt at admission is 76 kg. His lab values were normal except for low Hgb and Hct due to bleeding (which was well controlled). He was unconscious, thus was tube fed for one...

diabetes in this article
Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
