FAQs on Causes of Domestic Sewage & Industrial Effluents Video Lecture - Biology Class 12 - NEET

1. What are the main causes of domestic sewage?
Ans. The main causes of domestic sewage include the disposal of wastewater from residential areas, such as from toilets, kitchen sinks, laundry activities, and bathing. Additionally, improper maintenance and malfunctioning of septic tanks can also contribute to domestic sewage.
2. What are the main causes of industrial effluents?
Ans. Industrial effluents are primarily caused by the discharge of wastewater from various industrial activities. These activities can include manufacturing processes, chemical production, mining, and power generation. Improper waste management practices and inadequate treatment of industrial wastewater can contribute to the release of harmful effluents.
3. How do domestic sewage and industrial effluents impact the environment?
Ans. Domestic sewage and industrial effluents can have detrimental effects on the environment. They can contaminate water bodies, affecting the quality of water and endangering aquatic life. Nutrient enrichment from sewage can lead to eutrophication, causing excessive algae growth and depletion of oxygen. Toxic chemicals from industrial effluents can also harm ecosystems and pose risks to human health.
4. What are the health risks associated with exposure to domestic sewage and industrial effluents?
Ans. Exposure to domestic sewage and industrial effluents can pose various health risks. Contaminated water can transmit waterborne diseases, such as cholera, typhoid, and hepatitis. Industrial effluents containing hazardous chemicals can cause acute and chronic health problems, including skin irritations, respiratory issues, and even cancer, depending on the specific contaminants present.
5. How can the impacts of domestic sewage and industrial effluents be mitigated?
Ans. The impacts of domestic sewage and industrial effluents can be mitigated through proper wastewater management and treatment. Implementing effective sewage treatment systems, such as centralized wastewater treatment plants or individual septic tanks, can significantly reduce pollution levels. Industrial effluents can be treated using various techniques, such as biological treatment, chemical precipitation, or filtration, to remove harmful substances before discharge. Strict regulations and enforcement, along with public awareness and education, are also crucial in preventing and reducing pollution from domestic and industrial sources.
