The correct answer is D) All of the above.
The Musi River is a major river in the Indian state of Telangana. It is a tributary of the Krishna River. The Musi River is one of the most polluted rivers in India. The main sources of pollution in the Musi River are industrial discharge, urban sewage, and agricultural runoff.
Industrial discharge is a major source of pollution in the Musi River. Many industries located along the banks of the river discharge their wastewater directly into the river without any treatment. This wastewater contains a variety of pollutants, including heavy metals, organic chemicals, and pathogens. These pollutants can cause a variety of problems, including fish kills, algae blooms, and human health problems.
Urban sewage is another major source of pollution in the Musi River. Many cities and towns located along the banks of the river do not have adequate sewage treatment facilities. This untreated sewage is discharged directly into the river. This sewage contains a variety of pollutants, including human waste, detergents, and other chemicals. These pollutants can cause a variety of problems, including fish kills, algae blooms, and human health problems.
Agricultural runoff is also a major source of pollution in the Musi River. Farmers often use fertilizers and pesticides to grow their crops. These chemicals can wash off of the fields and into the river during heavy rains. These chemicals can cause a variety of problems, including fish kills, algae blooms, and human health problems.
The pollution in the Musi River has a number of negative impacts on the environment and human health. The pollution can kill fish and other aquatic life. It can also make the water unsafe for drinking, bathing, and irrigation. The pollution can also cause a variety of human health problems, including respiratory problems, skin problems, and cancer.
The government of Telangana has taken some steps to address the pollution in the Musi River. However, more needs to be done to clean up the river and protect the environment and human health.
