Human Urine Can Help Curb Pollution

A Spanish researcher has said that human and animal urine can also absorb carbon dioxide (CO2) and can help lower pollution.

Absorbing CO2 and other greenhouse gases in cities would require millions of tonnes of some naturally occurring substance. Urine is produced in large quantities and is close to the pollution hubs of large cities.

Air Pollution and Cancer Incidence: a Danish Cohort Study
Air pollution is on the increase and so are the associated risks. A recently published study links air pollution near residence and cancer.

"For every molecule of urea in urine, one mole (a unit to measure the quantity of a substance) of ammonium bicarbonate is produced along with one mole of ammonia that could be used to absorb one mole of atmospheric CO2," said study author Manuel Jimenez Aguilar, the Journal of Hazardous Materials reports.

After absorbing CO2, another unit of ammonium bicarbonate is produced, which is in use in China as a nitrogen fertilizer for the last 30 years.
