Hill streams of this region inhabit ichthyofauna of broad importance. However, increased anthropogenic activity possess deleterious consequence. The goal of the study conducted from January 2021 to July 2022 was to document and report the ichthyofaunal diversity of the hill streams in the Baksa district of Assam, India, its economic importance as well as potential threats associated with it. A total of 3182 fishes classified into 39 species, 13 families, and 5 orders were documented. Cypriniformes is the dominant order (71.24%), followed by Perciformes (17.76%), Siluriformes (5.97%), Symbranchiformes (3.65%), and Beloniformes (1.38%). These hill streams inhabit endangered, vulnerable, near-threatened, lower-risk-near-threatened species (IUCN, CAMP, and ICAR). Diversity indices indicate that these streams are rich in evenly distributed ichthyofauna. However, the recent spike in riparian deforestation, illegal fishing, and tourism-related plastic garbage possess a serious threat to these hill-stream ecosystems and inhabiting fish fauna. The consequences of riparian deforestation are looming as a severe future issue. Conservation of this ecosystem has become an important call to take on.

The sources of air pollutants include natural phenomena induced dust storms and poisonous gases emission through volcanic eruption, earth quacks and flash floods as well as anthropogenic activities induced dust and greenhouse gases including methane, Carbon monoxide (CO), Carbon dioxide (Co2) and other toxic gases emission through agricultural activities, transportation, mining, weapon testing, industrial processes and energy production activities. Particulate Matters (PM), nitrogen oxides, sulphur dioxide, ozone, black carbon and carbon monoxide are the main pollutants of concern, as they have been found to be linked with high incidence of respiratory diseases, cardiovascular diseases, cancer, mental retardation and neurological disorders in both human and animals. The impacts of indoor air pollutants like toxic dust particles, CO, CO2, Methane and Volatile Organic Compounds (VOCs) on human health vary depending on the level and duration of exposure but it can have devastating and long-lasting impacts on human health by causing acute respiratory diseases (ARD), chronic respiratory diseases (CRD), chronic obstructive respiratory diseases (COPD), neurological disorders, Alzheimer, mental retardation and cardiovascular diseases. The short-lived climate pollutants (SLCPs) such as tropospheric ozone, hydrofluorocarbons (HFCs), and black carbon have been reported to have devasting impacts on global climate regime, ecosystem services and threaten food and human livelihood security. To mitigate adverse impacts of air pollutants on global environment and food security, it is important to reduce emissions of major air pollutants including SLCPs through adoption of clean energy sources, implementing emission standards, increase green cover and promoting sustainable occupational and lifestyle practices. Continued research and public education efforts are essential to protect public health and the environment from the detrimental impacts of air pollutants at regional and global scale.
