Australian scientists have started monitoring air pollution levels of toxic, cancer-causing chemicals as part of a global project, explains an ABC News piece.
The researchers are taking air samples at weather stations in north-west Tasmania, Melbourne and Darwin as part of a push to ban the use of POPs (persistent organic pollutants), which are used in pesticides and manufacturing. The danger of these chemicals is that they do not break down and make their way through the food chains into our bodies in concentrations that can be quite high and potentially deadly.
"They can effect cardiovascular disease, so they can affect the way we breathe and our heart rates etc, so cause heart disease," the article quotes CSIRO's Melita Keywood as saying. "They also cause cancers and they also affect the way we metabolise food."
The results will be sent to the UN and used to develop a global approach to reducing exposure to the potentially deadly chemicals.
