Respondents 4 to 11 and 17 to 23 are some of such industrial units established in Cuddalore SIPCOT area at different points of time.

IT is seen from the materials on record that the residents of the Cuddalore SIPCOT area themselves have formed SIPCOT Area Community Environmental Monitors (SACEM) and brought out several reports in respect of the pollution in SIPCOT area. One such report titled 'Gas Trouble' Air quality in SIPCOT, Cuddalore was published by 'The Hindu' on 21.9.2004, under the caption 'villages in Cuddalore industrial estate toxic hot spot' stating that twenty thousand residents of 10 villages and several hamlets around the over two decade old SIPCOT industrial estate near Cuddalore town are exposed to high levels of 22 Volatile Organic Compounds (VOCs) including eight cancer causing ones, mostly released by factories in the complex. According to the said report, the levels of some of the chemicals in the SIPCOT area were at least 1,000 times higher than those prevailing in South Africa, Thailand and the Philippines. The report also justified the villagers' demands for continuous air monitoring, including for toxic gases, an aggressive air pollution elimination programme, long-term health monitoring, specialised health care facilities for residents and a ban on the setting up or expansion of any polluting facility in the complex.
