A new study has found that 6 out of every 10 people on Earth still do not have access to flush toilets or other adequate sanitation.

The new estimates used what the authors regarded as a more realistic definition from the standpoint of global health, since untreated sewage is a major cause of disease.
They refined the definition of "improved sanitation" by discounting sewage systems lacking access to sewage treatment.
They concluded that about 60 percent of the world's population does not have access to improved sanitation, up from the previous estimate of 38 percent.
The study has been published in ACS' journal Environmental Science and Technology.
