Summary
Biomass and coal cofiring retrofits may increase air pollution and premature deaths. Targeted pollution control in high-risk regions can mitigate these health risks and promote a fair energy transition.
Area of Science:
- Environmental Science
- Public Health
- Energy Policy
Background:
- Coal power plants are being retrofitted with biomass cofiring for low-carbon energy goals.
- This retrofitting approach (Biomass and Coal Cofiring Retrofit - BCCR) may introduce environmental and health risks, exacerbating regional inequalities.
Purpose of the Study:
- To develop a comprehensive framework for evaluating the risks associated with BCCR in China.
- To quantify the potential increases in air pollutants and related health impacts.
- To analyze regional disparities in health risks.
Main Methods:
- Utilized a comprehensive framework to assess BCCR risks.
- Modeled projected increases in SO2, PM2.5, and NOx emissions.
- Estimated nationwide premature mortalities linked to PM2.5 concentrations.
- Analyzed disparities in health risks across different provincial groups.
Main Results:
- Average increases in SO2, PM2.5, and NOx emissions are projected at 27.9%, 38.04%, and 42.79% respectively.
- Nationwide premature mortalities from PM2.5 are expected to rise by 23.53% on average by 2030.
- Provinces with the highest health risks face risks 19 times greater than those with the lowest.
Conclusions:
- Implementing targeted pollution control strategies in high-risk areas is economical and effective.
- Such strategies can reduce overall pollutant emissions and lessen regional health disparities.
- Stringent pollution control measures are recommended for BCCR in necessary regions to ensure a just clean energy transition.

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
