Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance or energy. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water.
Water pollution is the contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources: sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution is either surface water pollution or groundwater pollution. This form of pollution can lead to many problems, such as the degradation of aquatic ecosystems or spreading water-borne diseases when people use polluted water for drinking or irrigation. Another problem is that water pollution reduces the ecosystem services that the water resource would otherwise provide.
Sphingomonas was defined in 1990 as a group of Gram-negative, rod-shaped, chemoheterotrophic, strictly aerobic bacteria. They possess ubiquinone 10 as their major respiratory quinone, contain glycosphingolipids (GSLs), specifically ceramide, instead of lipopolysaccharide (LPS) in their cell envelopes, and typically produce yellow-pigmented colonies. The GSL serves to protect the bacteria from antibacterial substances. Unlike most Gram-negative bacteria, Sphingomonas carries endotoxins and has a hydrophobic surface characterized by the short nature of the GSL's carbohydrate portion.
A water bottle is a container that is used to hold liquids, mainly water, for the purpose of transporting a drink while travelling or while otherwise away from a supply of potable water.
In Nigeria, there has been a major progress in the improvement of health since 1950. Although lower respiratory infections, neonatal disorders and HIV/AIDS have ranked the topmost causes of deaths in Nigeria, in the case of other diseases such as monkeypox, polio, malaria and tuberculosis, progress has been achieved. Among other threats to health are malnutrition, pollution and road traffic accidents. In 2020, Nigeria had one of the highest cases of COVID-19 in Africa.As a matter of fact,Nigeria had the highest case in West Africa.
Water supply and sanitation sector in Ghana is a sector which is in charge of the supply of healthy water and also improve the sanitation of water bodies in the country Ghana.
Ghana Innovation Marketplace 2009, abbreviated as GIM 2009, is an innovation competition that seeks innovative strategic solutions to Ghana's growing problem of solid waste management. The World Bank Group, in collaboration with the Government of Ghana, and other partners are sponsoring GIM 2009 to recognise and fund social entrepreneurs, small-actors and partner organisations/CSOs in the waste management sector.
Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated water safe to drink. Water contaminated with non-biological agents such as toxic chemicals or heavy metals require additional steps to make the water safe to drink.
Water scarcity in Africa is predicted to reach dangerously high levels by 2025 when it is estimated that about two-thirds of the world's population may suffer from fresh water shortage. The main causes of water scarcity in Africa are physical and economic scarcity, rapid population growth, and climate change. Water scarcity is the lack of fresh water resources to meet the standard water demand. Although Sub-Saharan Africa has a plentiful supply of rainwater, it is seasonal and unevenly distributed, leading to frequent floods and droughts. Additionally, prevalent economic development and poverty issues, compounded with rapid population growth and rural-urban migration have rendered Sub-Saharan Africa as the world's poorest and least developed region.
Agbogbloshie is a nickname of a commercial district on the Korle Lagoon of the Odaw River, near the center of Accra, Ghana's capital city in the Greater Accra region. Near the slum called "Old Fadama", the Agbogbloshie site became known as a destination for externally generated automobile and electronic scrap collected from mostly the western world. It was alleged to be at the center of a legal and illegal exportation network for the environmental dumping of electronic waste (e-waste) from industrialized nations. The Basel Action Network, a small NGO based in Seattle, has referred to Agbogbloshie as a "digital dumping ground", where they allege millions of tons of e-waste are processed each year.
Resource recovery is using wastes as an input material to create valuable products as new outputs. The aim is to reduce the amount of waste generated, thereby reducing the need for landfill space, and optimising the values created from waste. Resource recovery delays the need to use raw materials in the manufacturing process. Materials found in municipal solid waste, construction and demolition waste, commercial waste and industrial wastes can be used to recover resources for the manufacturing of new materials and products. Plastic, paper, aluminium, glass and metal are examples of where value can be found in waste.
Responsibility of water supply in Nigeria is shared between three (3) levels of government – federal, state and local. The federal government is in charge of water resources management; state governments have the primary responsibility for urban water supply; and local governments together with communities are responsible for rural water supply. The responsibility for sanitation is not clearly defined.
Plastic pollution is the accumulation of plastic objects and particles in the Earth's environment that adversely affects humans, wildlife and their habitat. Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. Plastics are inexpensive and durable, making them very adaptable for different uses; as a result, manufacturers choose to use plastic over other materials. However, the chemical structure of most plastics renders them resistant to many natural processes of degradation and as a result they are slow to degrade. Together, these two factors allow large volumes of plastic to enter the environment as mismanaged waste and for it to persist in the ecosystem.
Biodegradable additives are additives that enhance the biodegradation of polymers by allowing microorganisms to utilize the carbon within the polymer chain as a source of energy. Biodegradable additives attract microorganisms to the polymer through quorum sensing after biofilm creation on the plastic product. Additives are generally in masterbatch formation that use carrier resins such as polyethylene (PE), polypropylene (PP), polystyrene (PS) or polyethylene terephthalate (PET).
Trashy Bags Africa is a commercial venture in Accra, Ghana, which turns plastic waste into reusable shopping bags, fashion accessories, school supplies, and other products.
A packet or sachet is a small bag or pouch, made from paper, foil, plastic film or another type of packing material, often used to contain single-use quantities of foods or consumer goods such as ketchup or shampoo. Packets are commonly opened by making a small rip or tear in part of the package, and then squeezing out the contents.
Water in Africa is an important issue encompassing the sources, distribution and economic uses of the water resources on the continent. Overall, Africa has about 9% of the world's fresh water resources and 16% of the world's population. Among its rivers are the Congo, Nile, Zambezi, and Niger, and also has Lake Victoria, considered the world's second largest lake. Yet the continent is the second driest in the world, with millions of Africans still suffering from water shortages throughout the year.
Waste management in South Korea involves waste generation reduction and ensuring maximum recycling of the waste. This includes the appropriate treatment, transport, and disposal of the collected waste. South Korea's Waste Management Law was established in 1986, replacing the Environmental Protection Law (1963) and the Filth and Cleaning Law (1973). This new law aimed to reduce general waste under the waste hierarchy in South Korea. This Waste Management Law imposed a volume-based waste fee system, effective for waste produced by both household and industrial activities.
Menstrual hygiene management (MHM) or menstrual health and hygiene (MHH) refers to access to menstrual hygiene products to absorb or collect the flow of blood during menstruation, privacy to change the materials, and access to facilities to dispose of used menstrual management materials. It can also include the "broader systemic factors that link menstruation with health, well-being, gender equality, education, equity, empowerment, and rights". Menstrual hygiene management can be particularly challenging for girls and women in developing countries, where clean water and toilet facilities are often inadequate. Menstrual waste is largely ignored in schools in developing countries, despite it being a significant problem. Menstruation can be a barrier to education for many girls, as a lack of effective sanitary products restricts girls' involvement in educational and social activities.
