Article Synopsis
- The study examines lead (Pb) pollution in the Western Indian Ocean, using a 24-year coral record from Lakshadweep to understand historical and current contamination levels and their effects on the environment.
- Results show that lead concentrations in surface seawater nearly doubled from 1990 to 2013, mainly due to anthropogenic sources like aerosol pollution from land.
- The findings reveal significant differences in lead isotope distributions between the western and eastern Indian Ocean, indicating a substantial impact of human activity, which underscores the need for tailored environmental management in the region.
The study investigates the sources of metals in urban road dusts using elemental concentration and Pb isotopic ratios. The elemental concentrations are also utilized to determine the present heavy metal emissions as well as projected emissions till 2045. Bayesian mixing model for source apportionment highlights the significant contributions of both exhaust and non-exhaust sources to the metal-enriched urban road dusts, with each contributing approximately 40 %.
