Sulfur dioxide (SO2) can cause acid rain. Name one other pollutant that can cause acid rain. Describe the effects of acid rain on the environment. State three methods to reduce atmospheric SO2 pollution. Scientists in China measured the concentration of sulfur dioxide (SO2) in the atmosphere and sulfur in plant tissues from 1990 until 2005. They did not record any measurements between 1990 and 1996. Their results are shown in . 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 1990 1996 1997 1998 1999 2000 time / year atmospheric SO2 / µg m–3 plant tissue sulfur / % 2001 2002 2003 2004 2005 2006 plant tissue S atmospheric SO2 Key: Describe the trends in the concentrations of sulfur found in the atmosphere and in the plant tissues as shown in . You will gain credit for using the data in the graph to support your answer. Suggest why the concentration of sulfur in the plant tissues was calculated as a percentage of the dry mass of the plant tissue.
