Abstract

A disastrous sudden blackening of the river Kameng in Arunachal Pradesh, known as the river Jiya Bharali in Assam, was studied to find its cause and effects. The water of the river suddenly turned turbid and black on October 29, 2021, causing a large-scale death of fish for several days creating panic among the surrounding people. Samples of water and sediment were collected from different locations of the river and were analysed. The results indicate an increase in TSS consisting of aluminosilicates and oxides of Fe, Mn, Co, Ni, etc., mixed with water due to landslides. Coloured metal oxides were found to cause the blackening while toxicity and suffocation due to excess of suspended microscopic particles may have led to the death of fish. Preventive and curative measures for the disaster have been suggested.

2021 年 10 月卡门河/吉亚巴拉利河突然变黑的原因和影响

对阿鲁纳恰尔邦卡蒙河（在阿萨姆邦被称为吉亚巴拉利河）突然变黑的灾难性事件进行了研究，以找出其原因和影响。2021 年 10 月 29 日，河水突然变得浑浊发黑，导致鱼类大量死亡，并持续数日，引起了周围居民的恐慌。我们从河流的不同位置采集了水和沉积物样本，并对其进行了分析。结果表明，由于山体滑坡，由铝硅酸盐和铁、锰、钴、镍等氧化物组成的总悬浮物与水混合后有所增加。结果发现，有色金属氧化物是导致水体变黑的原因，而悬浮微粒过多可能导致鱼类中毒和窒息死亡。针对这一灾害提出了预防和治疗措施。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
