The organophosphate Azinphos-methyl has a 96-hour LC50 value of 3 ppb for rainbow trout. In an unfortunate incident, 200 g of this pesticide was sprayed on a field, and a subsequent heavy rainfall washed 35% of it into a nearby lake having a surface area of 30,000 m2 and an average depth of 0.5 m. Would the pesticide concentration in the lake water have been sufficient to kill a significant fraction of the rainbow trout in the lake?

Figure 1.16 seems at first to be simply a description of thephysical and chemical properties of a lake. Outline how livingorganisms participate in determining the physical and chemical(i.e., temperature and O2) patterns. Consider organisms livingboth in the lake and on the land surrounding the lake. Consideralso a research report that shows that dense populations of algaesometimes change the temperature structure of lakes by raisingthe thermocline and thereby increasing the thickness of the deep,cold layer; how could algal populations do this, and what couldbe the consequences for deep-water animals?

Environmentally conscious Susan has been told that a newelectric car will only generate 6 ounces of greenhouse gases (GHG) permile, but that a standard internal combustion car is double that at 12ounces per mile. However, the nature of electric cars is such that the new technology and electric batteries generate 30,000 lbs. of GHG to manu-facture and another 10,000 lbs. to recycle. A standard car generates only 14,000 lbs. of GHG to manufacture, and recycling with established tech-nology is only 1,000 lbs. Susan is interested in taking a systems approach that considers the life-cycle impact of her decision. How many miles mustshe drive the electric car for it to be the preferable decision in terms ofreducing greenhouse gases?

A biologics production process uses a series of vats to make pharmaceuticalproducts. Each vat contains a mixture of compounds and live organisms (e.g., bacteria) andmust be strictly controlled in terms of temperature, acidity, and other factors. Storage tanksare used between production steps. If a storage tank is full, the upstream batch is held in asteady state before it can be transferred to the storage tank. This is an example of which ofthe following?a. Balkingb. Blockingc. Renegingd. Starving
