“…However, the corresponding back trajectory (Figure 7) highlights an air mass arriving at 3800 m which is completely derived from the ground level (black line) of Uttar Pradesh and, in particular, from the Assam region, touching the regions on the banks of the Brahmaputra several times. As previously mentioned, this area is highly polluted, and the city of Guwahati (highlighted by a yellow-black asterisk in Figure 6) is one of the most polluted Indian cities and is often the subject of study due to the high rate of black carbon emission into the atmosphere [35,43].…”

In January 2016, a measurement campaign was carried out by the China Meteorological Administration, the Beijing Research Institute of Telemetry, and the Physics Department of the University of Naples “Federico II” in the Yulong Naxi Autonomous County (China) at 3200 m above sea level to evaluate the air quality in the high mountains with the lidar technique. Here we report on an interesting event that occurred on 16 January between 12.00 and 00.00 UTC, when a striking aerosol stratification was observed on the site. Aerosol transport events are studied starting from lidar characterization of different aerosol masses. From lidar signals at 355 and 532 nm, integrated on 30 min, the aerosol characterization is done in terms of aerosol depolarization ratio with a spatial resolution of 60 m and color ratio; these parameters allow for highlighting a phenomenon of aerosol transport from the Tibetan plateau planetary boundary layer and from northern India. The initial layer is composed of a mixture of aerosols characterized by average values of the aerosol depolarization ratio and the color ratio of (30 ± 2)% and (0.9 ± 0.2), respectively, indicating a large non-spherical aerosol composition. Then, the deposition of this aerosol load ensues, and aerosols with such features are progressively observed at lower altitudes.

“…In India, the use of naphthalene is very common as there is no public information and awareness regarding the possible impact of naphthalene. Few notable works on PAHs contamination have been carried out in soils of Guwahati, Assam (Das et al, 2016) and in Bharalu tributary of the Brahmaputra River (Hussain et al, 2014). Various other cases of naphthalene ingestion have been reported in India (Annamalai et al, 2012; Chauhan et al, 2014; Kundra et al, 2015).…”

Exposure to large concentrations of organic PAH (polycyclic aromatic hydrocarbon) compound naphthalene can potentially accumulate inside the body, damage the cells and causes serious health issues. The current understanding of naphthalene exposure to many food fish species is limited. For a comprehensive understanding of naphthalene toxicity to fish health, dose dependent exposure was carried out in Anabas testudineus, an important food fish of Asia. Fish were exposed to sublethal concentrations of naphthalene (4.2, 4.4, 4.6, 4.8 and 5 mg L−1) for a period of 72 h. Activity analysis of lipid peroxidation and antioxidant enzymes in liver and muscles of the Anabas testudineus showed a marked increase in the lipid peroxidation activity in almost all the experimental groups. In contrast, the enzymatic activity of antioxidants like catalase, glutathione peroxidase and non‐enzymatic antioxidant glutathione decreased in both liver and muscle tissue. The results imply that increasing doses of naphthalene induced lipid peroxidation and the decreasing levels of antioxidants were incapable of reducing the stress exerted by naphthalene. This study is beneficial for evaluating the effect of LMW (Low molecular weight) naphthalene on fish and highlights the specific biomarker response signifying PAHs toxicity in fish.
