Air pollutants

<p dir=”ltr” style=”text-align: justify;”>The line graph compares the amount of emissions released into the air from three different sources, between 1990 and 2005.</p>
<p dir=”ltr” style=”text-align: justify;”>Overall, the total number of air pollutants gradually declined over the period shown. While the figures for industry and households decreased over the period, the figures for transport saw an increase.</p>
<p dir=”ltr” style=”text-align: justify;”>In 1990, a total of nearly 8 million tonnes of air contaminants were emitted from the three mentioned sources, with the largest figure belonging to industry, at 6 million tonnes. The amount of pollutants due to transport and households were the same, at approximately 1 million tonnes each.</p>
<p dir=”ltr” style=”text-align: justify;”>The total number of pollutants discharged into the air gradually reduced over the next fifteen years, with the total figure declining to about 5 million tonnes by 2005. In addition, air pollutants from industrial activity also decreased over time, from just under 6 million tonnes in 1990 to about 2 million tonnes in 2005. Despite the figures for households and transport being equal at the beginning of the period, the quantity of air pollutants from transport saw a small increase to 3 million tonnes by 2005, while air pollutants from households experienced a drop to a negligible amount.</p>
