Black carbon (BC) is produced due to the incomplete combustion of fossil fuels and rapidly accelerates the globe. The study of the source apportionment exploration of BC is inaccurate due to lacking observational limitations and uncertainties in emission inventories. In the present work, we measured BC mass concentrations using a 7-wavelength Aethalometer (AE-33). In this study, BC mass concentration was ranging from 2 to 13.43 μgm⁻³ and was minimum during monsoon (3.23 ± 0.38 μgm^-3) and maximum in the winter season (11.68 ± 2.55μgm⁻³). The annual mean BC mass concentration and PM2.5 were reported as 6.60 ± 3.50 μgm⁻³ and 119.07 ± 43.44 μgm^-3, respectively. In overall study, the BC aerosol was contributing 6.92% (winter), 5.09% (summer), 3.79% (monsoon) and 5.25% (post-monsoon) to the total mass concentration of PM2.5. Backward Trajectories have shown that the airborne particulate matter comes from different directions in different seasons. Correlation analysis has found a strong relationship between BC and PM2.5 (r = 0.89, r² = 0.80). However, an inverse relationship was noticed between BC and temperature(r = −0.92), wind speed (r = −0.61), precipitation (r = −0.60) and humidity (r = −0.52) during the observational period. Apart from describing BC's atmospheric impacts, the health risk assessment of BC during various seasons over Jamshedpur city is also illustrated in detail.

黑碳 (BC) 是由于化石燃料的不完全燃烧而产生的，并在全球范围内迅速加速。由于缺乏观测限制和排放清单的不确定性，对 BC 源分配探索的研究是不准确的。在目前的工作中，我们使用 7 波长风化计 (AE-33) 测量了 BC 质量浓度。在本研究中，BC 质量浓度范围为 2 至 13.43 μgm ^-3并且在季风期间最小（3.23 ± 0.38 μgm ^{-3 ）}，在冬季最大（11.68 ± 2.55 μgm ^-3）。年平均 BC 质量浓度和 PM2.5 报告为 6.60 ± 3.50 μgm ^-3和 119.07 ± 43.44 μgm ^-3，分别。在总体研究中，BC 气溶胶对 PM2.5 的总质量浓度贡献了 6.92%（冬季）、5.09%（夏季）、3.79%（季风）和 5.25%（季风后）。后向轨迹表明，空气中颗粒物在不同季节来自不同方向。相关性分析发现 BC 与 PM2.5 之间存在很强的相关性（r  = 0.89，r ²  = 0.80）。然而，BC与温度（r  =-0.92）、风速（r  =-0.61）、降水（r  =-0.60）和湿度（r = -0.52) 在观察期内。除了描述不列颠哥伦比亚省的大气影响外，还详细说明了不列颠哥伦比亚省在詹谢普尔市不同季节的健康风险评估。
