A new study released by Toxics Link, ‘Dirty Trail: Detergent to Water Bodies’, has found alarming levels of the toxic chemical nonylphenol in detergents as well as in river water in India. The detergent samples were taken from the local markets of Delhi and water from six rivers i.e. Garh Ganga and Hindon in Uttar Pradesh, Krishnan in Andhra Pradesh, Tapti in Gujarat, Bandi in Rajasthan, Mahanadi in Odisha and Ambazari lake in Nagpur.
Pointing towards the danger nonylphenol, the stady states, it is “a xenobiotic and an endocrine disrupting chemical is used largely in the production of nonylphenol ethoxylates (NPE)”, which is “extensively used as a surfactant and in other industrial applications as well as in day to day consumer products.”
Pointing out that NPE “generally breaks down to Nonylphenol in natural environmental conditions and enters into the ecosystem”, and also enters into “the food chain, where it bio-accumulates and can pose serious environmental and health risks”, the study says, “USA, the European Union and China have “acknowledged the menace of this chemical and have put restrictions on its use in various industrial processes and have shifted towards safer alternatives.”
While these countries phased out nonylphenol’s use from detergent in these countries long time ago, India has prohibited the use of nonylphenol in cosmetic products (2009), but there is “no regulation on its use in surfactants or other consumer products”, the study says, adding, “Further, there is no public information available on the possible impacts of the chemical and to minimize the risks associated with it.”
The study states, concerns have been raised about nonylphenol’s potential to cause carcinogenic effects on the human body. It says, “Since the chemical has been classified as an endocrine disrupting chemical (EDC) and is found to be having a number of reproductive and hormonal effects on the exposed humans, it has been detected in human breast milk, blood, and urine and is associated with reproductive and developmental effects in rodents.”
It states, “Studies have established the linkage of nonylphenol with cancer”, adding, “It can enhance the progression of cancer. A study has concluded that the presence of nonylphenol induces the cells and increases the chances of colon cancer.”Pointing out that the “World Health Organization in its risk assessment of nonylphenol.”
Some key findings of the study are:
Nonylphenol is known to be an endocrine disrupting chemical which is hazardous to the environment and human health besides also posing a threat to aquatic life and other fauna. The chemical has also been found to have a number of adverse reproductive and hormonal effects on human beings and can cause carcinogenic effects on the human body.
Considering its harmful effects, nonylphenol has been highly regulated by many countries globally. The United States, European Union and even China have phased out nonylphenol from detergent completely. Further Denmark has completely banned the use of nonylphenol ethoxylates (NPEs) in textile and leather industries and the EU has restricted the use of NPEs in products and product formulations to 0.01% in textile and other industries.
Moreover efforts are being made to restrict the use of the chemical in drinking water. Canada has set the standard of nonylphenol at 1.0 microgram per liter (µg/L) in freshwater while the US Environmental Protection Agency (EPA) has established water quality criteria for nonylphenol at 6.6 µg/L for acute exposures and 1.7 µg/L for chronic exposures.
“Despite Nonylphenol being a toxic chemical it was found in very high concentration in all the detergents samples that were tested. It is also a matter of grave concern that high concentration of Nonylphenol in river water samples can cause irreversible harm to aquatic organisms,” said Piyush Mohapatra, senior programme coordinator, Toxics Link.
In the Toxics Link study the concentration of nonylphenol was found to be as much as eight times more than the prescribed BIS standard for phenolic compounds and over 100 times as compared to the US EPA safety standard for water quality criteria.
The study has proposed the following recommendations:
