The tragic incident in Giaspura, Ludhiana, where 11 people died due to a gas leak, has raised concerns about the dangers of exposure to toxic gases. While four people have been hospitalised, it is reported that they are out of danger. The incident is believed to have been caused by the release of a neurotoxic gas, which affected the nervous system of the victims.
What are Neurotoxins?
Neurotoxins are poisonous substances that can directly affect the nervous system. They can alter the normal activity of the nervous system, disrupting or even killing neurons or nerve cells. These cells are crucial for transmitting and processing signals in the brain and other parts of the nervous system.
Neurotoxic Gases and their Effects
Methane, hydrogen sulphide, carbon monoxide, and carbon dioxide are common neurotoxic gases. While methane and carbon monoxide are odourless gases, hydrogen sulphide has a pungent odour and in higher concentrations, it can be fatal for humans.
The gas leak in Giaspura is suspected to be caused by the release of hydrogen sulphide, which has a distinct rotten egg smell. This gas is often produced by bacterial decomposition of organic matter in wastewater and sewage. To remove gases such as hydrogen sulphide from wastewater, chemical oxidation is done, where oxidants such as hydrogen peroxide are added to the wastewater.
Prevention and Safety Measures
It is important to take preventive measures to avoid such incidents in the future. It is essential to ensure that toxic gases are not released into the environment, and measures must be taken to remove them safely. Some of the safety measures that can be taken are:
- Regular monitoring of gases in industrial areas where such gases are produced or released.
- Proper storage and handling of hazardous materials.
- Adequate ventilation systems to remove toxic gases.
- Personal protective equipment for workers in hazardous areas.
