Smog

Thermal inversions

• increase the rate of smog formation

• trap high concentrations of pollution as ground level

• result in increased levels of acid deposition

• reduce the negative effects of VOC's

Scientists have discovered that Volatile Organic Compounds (VOCs) emitted from trees can contribute to photochemical smog formation. Data in the table above were collected in 2006 and 2014 in Berlin, Germany. Isoprene is a VOC released by some tree species. Impact factor refers to the percentage of ozone attributed to the isoprene. Which of the following claims is best supported by the data shown in the table?

• Ozone levels are not a serious air quality concern in Berlin.

• Ozone levels in Berlin were consistently higher in 2014 than in 2006.

• Isoprene’s contribution to ozone levels in Berlin was greatest in July of both years.

• Isoprene levels were negatively correlated with maximum temperature.

Data in the table above were collected in 2006 and 2014 in Berlin, Germany. Isoprene is a VOC released by some tree species. Impact factor refers to the percentage of ozone attributed to the isoprene. Which of the following best describes the relationship between variables in the data table?

• Impact factor causes a change in temperature maximum.

• Isoprene levels vary depending on traffic and urbanization.

• Ozone maximum is correlated to average and maximum temperature.

• Changes in average temperature are linked to changes in land use in Berlin.
