Study links Black Carbon with premature deaths:
A team of researchers conducted a Study on black carbon and its impacts on health.
- Black Carbon has a significant adverse effect on human health and can lead to a premature death.
- The Indo-Gangetic plain is exposed to Black Carbon (BC) with serious implications on regional climate and human health.
- Mortality rises linearly with an increase in air pollutants level and shows adverse impact at higher levels.
Relevance and significance of the study:
- The inclusion of BC as a potential health hazard inspires and provides a background for more epidemiological studies to provide evidence of health effects of air pollutants from different parts of India.
- This will help government and policy-makers for better planning to mitigate the adversity associated with changing climate-air pollution-health nexus.
What is black Carbon? What are the concerns?
Black carbon results from the incomplete combustion of fossil fuels and biomass. BC is produced both naturally and by human activities as a result of the incomplete combustion of fossil fuels, biofuels, and biomass.
- Primary sources include emissions from diesel engines, cook stoves, wood burning and forest fires.
- It is a short-lived pollutant that is the second-largest contributor to warming the planet behind carbon dioxide (CO2).
Despite similar names, carbon black should not be confused with black carbon. What is Carbon Black? Click here ( Read very briefly from an exam point of view. Preferably the time to save time)
