Study links increased black carbon pollution to increase in cases of lung adenocarcinoma worldwide

Green Car Congress

NOVEMBER 28, 2021

An international team of scientists, led by NTU Singapore, has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. This study, done in collaboration between NTU and the Chinese University of Hong Kong, showed that a 0.1 Black carbon is a pollutant that is classified as under PM 2.5.
