Scientists Use Algae to Fight Against Endosulfan Pollution

PALAKKAD: As many as eight samples of endosulfan have been collected by the expert team and it was informed that by October 20, one of the eight samples will be sent to Salim Ali Institute in Hyderabad to get it tested. The remaining samples will behanded over to agencies that will come up with suitable technologies to detoxify and dispose it.

“Once we get the test results from Salim Ali Institute, we will invite expression of interest from agencies like Ramki, Meridy etc for detoxifying and disposing the endosulfan.

We will give samples of endosulfan to these agencies to assess its chemical combination to come up with a demonstration of what they are supposed to do for disposing it. We will have the test results from SAI as reference to assess the authenticity of the technology they put forward,” said Dr Muhammad Asheel, assistant nodal officer of Endosulfan Rehabilitation Cell.

He also said that the deal would be fixed by taking into account the cost, environmental impact and feasibility of technology. “Once we select an agency, the endosulfan will be handed over to them for disposal under the strict monitoring of government officials,” said Asheel.

HRPFY claims that they had a technology for disposing endosulfan. In what appears as promising, Human Rights Protection Foundation Udupi (HRPFU), a social organisation, has come out with a claim that they had developed an eco-friendly and less expensive technology for neutralising the existing stock of endosulfan.

This new technology developed by the HRPFU is absolutely natural and as part of the organisation’s social commitment they won’t charge for this technology, claimed HRPFU. The added advantage of this new technology is that it could be used to purify the soil, water and the environment which were polluted of endosulfan.

“The whole idea behind this method in simple statement is, using organisms in nature for neutralising endosulfan,” said Dr Ravindranath Shanbhag.

He also said there are certain species or algae in nature which can biodegrade endosulfan to endodiol which is not harmful.

“The algae named Anabaena PCC7120 and Anabaena flos-aquae can contribute in detoxification pathways of endosulfan in the soil environment. The other algae like Fusarium ventricosum and Pandoraea species are found to degrade about 90% of one litre endosulfan in 15 days.

“These algae can be used for the detoxification of endosulfan in contaminated soils, waste dumps and water bodies,” added Dr Ravindranath Shanbhag.
