Unscramble the Blue Letters


There’s a wide virteay of known pollutants but they all fall into two categories. The first are primary pollutants. These toxic compounds are directly emitted from a man-made or naturally occurring srocue. However, they don't always come from the pcleas you'd expect. Some large factories mostly generate water vapor, with only small queitatnis of pollutants mixed in. Conversely, burning wood or dung can create polycyclic aromatic hydrocarbons; dangerous compounds that have been linked to several tpeys of cecanr, as well as long-term DNA daamge. In all cases, pollutants interact with regional weather patterns and topography, which can keep compounds local or spread them kilometers away.

Original Text


There’s a wide variety of known pollutants but they all fall into two categories. The first are primary pollutants. These toxic compounds are directly emitted from a man-made or naturally occurring source. However, they don't always come from the places you'd expect. Some large factories mostly generate water vapor, with only small quantities of pollutants mixed in. Conversely, burning wood or dung can create polycyclic aromatic hydrocarbons; dangerous compounds that have been linked to several types of cancer, as well as long-term DNA damage. In all cases, pollutants interact with regional weather patterns and topography, which can keep compounds local or spread them kilometers away.
