However, the cause of leakage from the chemical factory is still unknown as per the study.

To note, seven people, including three children, had died after inhaling fumes seeping from the pipeline of a chemical factory in Biswan of Sitapur. The deceased, hailing from Kanpur, were those sleeping inside a carpet factory adjacent to the chemical factory.

Chief minister Yogi Adityanath had taken note of the accident and instructed officials to monitor the situation.

The report said as per toxicology analysis it was confirmed that the leaked chemical was Lindane (gamma-hexachlorocyclohexane). The toxicological analysis revealed the presence of Lindane in excessive quantities in water (0.461– 0.500 μg/L) and soil (1.030–2.100 μg/L) in the area.

“A case search from house-to-house was conducted and calculated the attack rate (AR) and case-fatality rate (CFR) based on gender and age. At the leakage site, we conducted an environmental investigation and sent the substances for forensic analysis,” said the report.

“We detected 23 cases and seven deaths among 2,942 inhabitants. The case’s median age was 42 years (range, 2-64 years). AR was also discovered to be greater in males than in women. It was also found that all 23 case-patients who were sleeping or visiting the chemical leakage site had symptoms, and all seven cases who were sleeping within 150 metres of the leakage site died,” the report said.
