Following a large marine oil spill, managers must decide among booms, skimmers, dispersants, sorbents, biological agents, and physical shoreline cleaning. The oil is spreading toward a sensitive coastline, wildlife is already being affected, and some of the petroleum is beginning to weather. Based on the lecture, which strategy best reflects the fact that oil-spill response usually requires different methods for different functions?

Two regions receive similar atmospheric inputs of sulfuric and nitric acids. Region X contains lakes surrounded by deep soils rich in limestone, while Region Y contains lakes surrounded by shallow soils with little limestone. After years of acid deposition, Region Y shows a much stronger decline in lake pH. Which interpretation is most consistent with the lecture?

A farmer repeatedly applies a broad-spectrum insecticide to control one crop pest. After several seasons, the target insect becomes harder to control, natural predators are less abundant, and previously minor pest species begin causing significant crop damage. Pesticide residues are also detected in nearby surface water. Which explanation best accounts for this combination of observations?

An agricultural watershed contributes nitrogen and phosphorus to a slow-turnover lake for many years. Algal growth increases, sunlight penetration decreases, dead organic material accumulates, and microbial decomposition intensifies. Fish kills later occur even though the original pollutants were nutrients rather than directly toxic chemicals. Which chain of events best explains the fish mortality?

A wastewater discharge containing large amounts of biodegradable organic matter enters a flowing stream. Downstream, bacterial decomposition increases sharply. Dissolved oxygen begins to fall, sensitive fish disappear, and organisms tolerant of low-oxygen conditions become more common. Farther downstream, dissolved oxygen gradually rises and normal aquatic communities begin returning. Which interpretation best explains this sequence?

A city lies in a valley surrounded by mountains. During a calm, sunny period, a warm air layer develops above cooler surface air. Motor vehicles continue emitting nitrogen oxides and hydrocarbons throughout the morning, and pollutant concentrations near the ground rise sharply. Based on the processes presented in the lecture, which explanation best integrates the meteorological and chemical causes of the pollution episode?
