What You'll Learn
Household air pollution
Domestic pollution refers to the contamination of water bodies by waste generated from households. This includes waste from kitchens, bathrooms, and laundry facilities, as well as sewage, which can contain harmful bacteria and chemicals.
The use of polluting fuels and technologies also poses safety risks, such as burns and scalds from open fires and unstable stoves. Kerosene, commonly used for cooking and sold in refilled soda bottles, is the leading cause of childhood poisonings. Additionally, fuel collection increases the risk of musculoskeletal damage from carrying heavy loads and the risk of injury or violence, especially in insecure areas.
To address household air pollution, the World Health Organization (WHO) has issued guidelines for indoor air quality, recommending clean fuels and technologies such as solar, electricity, biogas, liquefied petroleum gas (LPG), and natural gas. These alternatives can significantly reduce health-damaging pollutants and protect the health and environment of those affected by household air pollution.

Health risks of domestic pollution
Domestic pollution refers to the contamination of water bodies by waste generated from households, as well as the degradation of the environment caused by human activity in the home. Domestic pollution can also refer specifically to household air pollution, which is generated by the use of inefficient and polluting fuels and technologies in and around the home. This type of pollution contains a range of health-damaging pollutants, including small particles that penetrate deep into the lungs and enter the bloodstream.
Household air pollution is a major cause of health issues worldwide, particularly in rural areas of low-income countries. It is responsible for an estimated 3.2 million deaths per year, including over 237,000 children under the age of five. The leading causes of these deaths are lower respiratory infections, such as pneumonia, and chronic obstructive pulmonary disease (COPD). Exposure to household air pollution almost doubles the risk of childhood lower respiratory infections and is responsible for 44% of all pneumonia deaths in children under five. It also contributes to 22% of all adult deaths from pneumonia.
In addition, household air pollution is a risk factor for acute lower respiratory infections in adults. It is estimated that 23% of all deaths from COPD in adults in low- and middle-income countries are due to exposure to household air pollution. Furthermore, 6% of deaths caused by household air pollution are due to lung cancer, with approximately 11% of lung cancer deaths in adults being attributable to exposure to carcinogens from household air pollution.
Other health issues caused by household air pollution include stroke, ischaemic heart disease, and cardiovascular disease. According to the Global Burden of Disease study, household air pollution and ambient particulate matter pollution are among the top risk factors for the loss of healthy life years. In 2019, household air pollution accounted for the loss of an estimated 86 million healthy life years, with the largest burden falling on women living in low- and middle-income countries.
The use of polluting fuels and technologies in households also poses safety risks. For example, kerosene, often sold in refilled soda bottles, is the leading cause of childhood poisonings. Additionally, fuel collection increases the risk of musculoskeletal damage from carrying heavy loads and the risk of injury or violence, especially in insecure areas. The burden of routinely carrying heavy loads of fuel can cause muscle strains, spinal injuries, fractures, pregnancy complications, and long-term physical strain.
Water pollution caused by domestic sources is also a significant issue. Sewage from households can contain disease-causing bacteria that can travel on any waste product. Harmful chemicals contained in cleaning products also contribute to water pollution, with phosphates in detergents and washing powders being harmful to aquatic life.

Water pollution
Domestic pollution refers to the contamination of water bodies by waste generated from households. Wastewater from the kitchen, bathroom, and laundry facilities is the most common type of domestic pollution. Sewage is a term that refers to wastewater that contains faeces, urine, and laundry waste, among other things.
Domestic sewage is a major source of plant nutrients, mainly nitrates and phosphates. Excess nitrates and phosphates in water promote the growth of algae, sometimes causing unusually dense and rapid growths known as algal blooms. When the algae die, oxygen dissolved in the water declines because microorganisms use oxygen to digest algae during the process of decomposition. Anaerobic organisms then metabolize the organic wastes, releasing gases such as methane and hydrogen sulfide, which are harmful to the aerobic (oxygen-requiring) forms of life. This process, known as eutrophication, results in a nutrient-rich, algae-filled lake or river that is oxygen-deficient and waste-filled.
Another major contributor to water pollution is the use of synthetic cleaners, washing powders, and other household products. Phosphates are found in several detergents and washing powders, and they are used to soften water and clean clothes. However, these washing powders contain a variety of chemicals that are harmful to all aquatic life, including fish and other aquatic organisms.
Additionally, harmful chemicals from cleaning products contribute to water pollution. These chemicals can be released into the environment through improper disposal or use. Furthermore, the decomposition of organic matter in sewage reduces the amount of dissolved oxygen in the water, creating an anaerobic environment that can be harmful to aquatic life.

Solid waste
Domestic pollution is the contamination of water bodies by waste generated from households. Wastewater from the kitchen, bathroom, and laundry facilities is the most common type of domestic waste. Solid waste, a type of domestic waste, refers to any garbage, trash, refuse, or sludge from a wastewater treatment plant discarded by households.
To address these issues, proper waste management is essential for public and environmental health. The Resource Conservation and Recovery Act (RCRA), passed in 1976, provides a framework for hazardous and non-hazardous waste management. Materials regulated by RCRA are known as "solid wastes" and are subject to additional regulation if classified as hazardous. Understanding the definition of solid waste is crucial for generators of hazardous waste to follow the appropriate regulations.
Reducing solid waste through reuse, recycling, and composting can improve public health, conserve energy and natural resources, and reduce pollution and greenhouse gas emissions. Counties and states can implement household hazardous waste programs and provide funding for recycling initiatives to prevent toxic chemicals from harming the environment and human health.

Sewage
Domestic pollution refers to the contamination of water bodies by waste generated from households, including permanent and seasonal inhabitants in a catchment area. Sewage is a type of wastewater that is produced by a community of people and is typically transported through a sewer system. It includes wastewater from residences and commercial, institutional, and public facilities in the locality.
The disposal of sewage is a challenging task, as all options carry risks of causing water pollution. These options include dilution in water bodies, marine outfalls, land disposal, and sewage farms. Sewage overflows and leaks from outdated or poorly maintained infrastructure can result in sewage spilling onto streets and parks and eventually pouring into rivers and streams. This can have severe health consequences, as germs and pathogens in the sewage can cause various illnesses, such as gastroenteritis and ear infections.
To address the issue of sewage pollution, it is crucial to invest in modernizing and upgrading wastewater infrastructure. Additionally, natural areas should be protected and expanded to prevent stormwater from rushing into sewers and causing overflows.
