A cost-effective way of arsenic sensing and removal

IANS  |  Kolkata 

A Kolkata-based company in partnership with the and Research has come up with a cost-effective and user-friendly detection and removal sensor that is capable of sensing soluble (3).

"It is very different from the present day's available sensors, it is very easy to use, very cost effective and anyone can use it to detect easily," said Sanjib Parial, MD of the manufacturing company.

The product 'Arsenic Sensor and Removal Media' was unveiled on Wednesday.

"In the currently available media, the solution is provided with a newly synthesised polymer adopting green synthetic protocols," he said.

As per WHO, soluble inorganic arsenic is acutely toxic. Intake of inorganic arsenic over a long period can lead to chronic arsenic poisoning (arsenicosis), diabetes, cardiovascular diseases and cancer.

The arsenic sensing and removal mechanisms had were not cost effective.

"The arsenic sensor is capable of sensing soluble arsenic (3), it is so soluble that it is very problematic to detect and remove it" said Parial.

"The sensor can sense up to parts per billion (ppb) level, which would be very useful. There are many techniques which sense parts per million (ppm), so ppm to ppb will make a lot of difference in sensitivity," exclaims IISER

The only country which mines arsenic is Arsenic pollution is a big problem in Bengal and neighbouring states.

"They are mining for a commercial enterprise, therefore, they can implement solutions at the company level but our arsenic is coming in the drinking water," said Thirumalachari Ramasami, former to the government of India,

"At this stage, we are quite far away, in fact, the whole world is far away," Ramasami told IANS when asked about the effective management of this

According to WHO, the permissible limit of arsenic in groundwater is 0.1 mg per litre. In the permissible arsenic level in drinking water was recently revised from 0.05 mg/l to 0.01 mg/l by the

In Bengal Malda, Murshidabad and have higher levels of arsenic concentration.

"For instance in district level of arsenic concentration is around 2.5ppm to 3ppm of arsenic in the water," mentioned Raja Shunmugam, of IISER.
