For people who feel NIOH study is the final report on Endosulfan

In response to claims connecting Endosulfan with human disorders in Kerala and Dakshina Kannada, six committees and expert groups including representatives from health, environment and agriculture departments were set up by the Govt of Kerala, Govt of India and the Govt of Karnataka to investigate into the reported linkage of Endosulfan with the various incidences of adverse health effects. Each committee has concluded that none of the alleged victims were proven to be affected by Endosulfan. The findings of these committees have been methodically dismissed and barely presented in the media. 

Many NGOs have produced reports linking Endosulfan to adverse health problems including cancer, infertility, birth defects and neurotic disorder. These reports were based on the National Institute of Occupational Health (NIOH) report which is proved to have been flawed. Despite this, international conventions and regulatory authorities worldwide have referenced this report while reviewing Endosulfan in both, the Rotterdam and Stockholm conventions. Recently, the National Human Rights Commission has also demanded a nationwide ban on Endosulfan based on this faulty report. Media, polity and other vested interests are also pressuring the government into discontinuing the studies on Endosulfan as they are already aware of what the results would be.

NIOH Errors: The NIOH report of 2002 titled ‘Report of the investigations of unusual illnesses allegedly produced by Endosulfan exposure in Padre village, of Kasargode district (N. Kerala),’ had fundamental inconsistencies as was observed by scientists and experts. 

Chemical residue analyses are performed on a sophisticated analytical instrument known as Gas Chromatography (GC) fitted with an Electron Capture Detector (ECD). Each GC-ECD has a lower limit for the minimum amount of a chemical that it can detect. This is expressed as Instrument Detection Limit (IDL). For the study under question, the NIOH had used GC-ECD (HP Model 6890) with the minimum IDL of 1 part per billion (1 ppb) for Endosulfan. In other words, the instrument used by the NIOH could not detect Endosulfan residues lower than 1 ppb. Yet, the NIOH report carries residue findings as low as 0.4 ppb and 0.5 ppb. Simply put, the residue levels reported by the NIOH fall below the minimum detection limit of the instrument used. These findings are scientifically indemonstrable, and are false and incorrect claims. 

Since, the raw data recorded by the NIOH for generating Endosulfan residue data in water, soil and blood samples were fundamentally flawed, its subsequent analysis is even more peculiar. For instance, the table no. 4 in the report shows the total Endosulfan (ppb) in six samples as 0.030 ± 0.18. Annexure -8 shows β Endosulfan residues as 0.0005± 0.001. It may be observed here is that the standard deviation goes beyond the mean (average) by up to 500 per cent. 

Modern GC-ECDs are fitted with computers that process the data gathered from the detectors into chromatograms and finally produce an easy-to-view report. Normal practices of a residue-testing laboratory require that copies of chromatograms of analysed samples are retained and stored in the laboratory/computer for future reference in case of any dispute. Therefore, letters were sent to NIOH under Right to Information Act (RTI Act) seeking copies of chromatograms relevant to this study. NIOH did not respond to requests for parting with raw data until the intervention of the Chief Information Commissioner. The case was heard at the Information Commission and it took three hearings and two orders by the Chief Information Commissioner for NIOH’s appellate authority to finally handover the 1,700 pages of raw data. The varying and inconsistent excuses given by the NIOH while refusing required information under the RTI Act were revealing signs of a cover-up. On examining the data, experts learned that the analysis conducted by NIOH had sure laboratory failings. The conclusions drawn did not corroborate with the raw data and the complete analysis is now being believed to be forged.

HIL workers at Kerala Endosulfan plant seek probe into NIOH study

Over 300 workers from the Hindustan Insecticides Limited plant manufacturing Endosulfan near Kochi at Kerala organised a rally today to oppose the unscientific approach adopted by environmental NGOs to seek ban on Endosulfan.

The workers demanded that their own experience and the farmers’ experience be taken into consideration as they work with the pesticide Endosulfan. Endosulfan was manufactured and used for more than 50 years across the world and continues to be in use in many countries without any ill effects to humans or environment. Endosulfan has proved to be harmless to beneficial insects and pollinating agents such as honey bees etc. It is among the top five insecticides in the world. In relation to Endosulfan’s use inside India the workers argued that Endosulfan would have shown its harmful effects elsewhere in India as it is extensively used across the country on crops such as cotton, sugarcane, spices, vegetables, fruits, etc. Millions of Indian farmers have been using Endosulfan for over 35 years and continue to use it as it has been cost effective and safe.

Speaking during the dharna, one of the workers’ representatives pointed out that Kerala had stopped use of Endosulfan in 2002 and it is strange that the harmful effects were brought to light only recently. Endosulfan was sprayed across 10000 acres of Cashew crops throughout Kerala, prior to the ban - had Endosulfan been the cause of physical problems inside Kasargod, the Kerala state should have witnessed similar cases elsewhere as well.

The workers’ representatives added that studies conducted by Kerala Sasthra Sahitya Parishad, Achuthan Commission, Kerala Agriculture University, IMA, Dubey Committee have concluded of no linkage between use of Endosulfan and the reports of health problems to the use of Endosulfan on the health problems reported at the Kasargod district of Kerala. All these studies have been conducted as recently as in the last eight years. It is their demand that, rather than ensuing a new study on the pesticide Endosulfan, it will be relevant to seek an independent investigation into the flaws observed in the study which was released by the National Institute of Occupational Health (NIOH).

The NIOH study was adopted by NGOs for propaganda against the generic pesticide Endosulfan since year 2002. To prove this point, the workers demanded that their blood samples be tested to validate against the published findings in NIOH report. The workers also made observations that the campaign against Endosulfan led by environmental NGOs like Thanal is suspect on their motives in the backdrop of studies conducted by other bodies. Based on unscientific approach, the demands made by local NGOs should not be taken into account for considering such a serious decision affecting our country’s agriculture and food security.

There are over 6000 workers employed in the manufacturing of Endosulfan in various plants of India and 400 of these workers are employed in the HIL plant.
