. Let’s consider the old saying, “If we eat an apple a day it keeps the doctor away!”, with respect to risk assessment. We assume person would consume approximately 7300 kg of apples over a lifetime (80 years). If we assume in any given week, the maximum quantity ingested is 1.75 kg of apples. The typical concentration of Alar (a pesticide used on the apples) residue on the apples is 1.8 ppm (1.8 mg/kg) for all the apples ingested over...

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...
