| An electronic cleaner produces negative ions that are attracted to the pollutants. |
| Since permissible limits in India are as high as to accommodate these pollutants, they cannot be booked under pollution control rules. |
| Finally, pollutants can change the nutrient balance of a waterbody, making it over-rich, a process known as eutrophication. |
