What is oxidative stress which is damaging the Sundarbans in India?
- Oxidative stress is a condition that occurs when pollutants, such as heavy metals and acidic components in the air, cause an imbalance between the production of reactive oxygenated species (ROS) and the ability of the mangrove ecosystem to neutralize them.
- ROS are highly reactive molecules that can damage cellular structures, including proteins, lipids, and DNA. When the production of ROS exceeds the antioxidant capacity of the mangrove cells, oxidative stress occurs, leading to cellular damage and potentially compromising the health and resilience of the ecosystem.
In the context of the Sundarbans mangrove ecosystem, oxidative stress induced by air pollutants like black carbon and heavy metals from Kolkata and the Indo-Gangetic Plain poses a significant threat to the delicate balance of this vital ecosystem.
