Sulfur dioxide irritates the respiratory tract and increases the risk of tract infections. Sulfur dioxide emissions in the United States in 1975 were officially estimated at 33 million tons per year. From a simple thermodynamic point of view, the preference for the formation of the dication [Li2(SO2)8]2 + over two monocations [Li(SO2)4]+ may be explained by the high lattice enthalpy of the dication–dianion salt (Figure 8). Terms of Service apply. Acid rain can: 1. cause deforestation 2. acidify waterways to the detriment of aquatic life 3. corrode building materials and paints. For general enquiries, feedback, complaints and compliments: Help us improve the content on our website or tell us what is working really well. Our weather conditions and low sulfur content of fuels reduce the potential for acid rain. Download the sulfur dioxide poster (PDF, . The recommended air quality standards for sulfur dioxide are: These standards are designed to protect sensitive individuals, such as children and asthmatics. Born–Fajans–Haber cycle for the dissociation of the dication [Li2(SO2)8]2 + into two [Li(SO2)4]+ cations. Acid rain can: In Queensland, there is less heavy industry than in Europe or North America, where the potential for forming acid rain from sulfur dioxide emissions is higher. The goal of the Clean Air Act Amendments of 1977 was to reduce that to 28 million tons per year by 1990 (Bauman and Crenshaw, 1977). Sulfur dioxide affects the respiratory system, particularly lung function, and can irritate the eyes. The sample (shown by the path of the blue dot) is drawn into the analyser by means of the vacuum pump, firstly through a filter to remove particles, and then through a scrubber to remove interfering gases, such as hydrocarbons. Because the hydration reaction of sulfuric acid is highly exothermic, dilution should always be performed by adding the acid to the water rather than the water to the acid. Reactants. ... Sulfuric Acid - H 2 SO 4. Products. Sulfur dioxide (SO2) is a colourless gas with a sharp, irritating odour. Enthalpies are given in kJ mol–1.76,82, Arthur L. Kohl, Richard B. Nielsen, in Gas Purification (Fifth Edition), 1997. Sulfur dioxide and water do not react to form sulfuric acid at a rate fast enough for an industrial process (Davenport & King, 2006).

Emission of fluorescence (light-producing) photons at higher wavelengths (around 350nm) follows this absorption of UV radiation by the molecule. The measured fluorescence is directly proportional to the concentration of sulfur dioxide in the sample. Go to the live air data service to check current levels of sulfur dioxide in the monitoring network. Cupric Sulfate - CuSO 4.

The goal of the Clean Air Act Amendments of 1990 is to achieve 8.9 million tons per year total emissions by 2001 (Public Law 101-549, 1990). 547 KB) Significant concentrations of sulfur dioxide are only measured in Queensland near large industrial sources. In Queensland, there is less heavy industry than in Europe or North America, where the potential for forming acid rain from sulfur dioxide emissions is higher.
