Concrete And Hazardous Wastes : An Evaluation Of The Issues And Relevant Waste Wastes

Pollution is one of the most concerning topics to talk about in today's modern world. It acts as a poison for anything that lives and breathes; it could toxify water, air, land, humans, and animals, and is not to be taken lightly.

Pollution is defined as the process of harmful substances being released into the air. Some of these substances include Carbon Monoxide, Sulphur dioxide, Lead and PM2.5. PM2.5 is small particles which are smaller than 25 thousandths of a millimeter. This polluted air will fill your lungs with tiny particles and cause Lung cancer, Asthma and other heart and lung diseases.

Hazardous waste is also an extreme contributor to poor environmental health in an individual’s life. In 2004, almost 5 million people died to exposure of chemicals, especially burning solid fuels that cause air pollution and secondhand smoke (WHO, 2016). Less than a third of countries worldwide do not have regulations on controlling lead paint sale and use, a strong impact on the amount of hazardous waste globally (WHO, 2016).

Environmental pollution is defined as the unfavorable alteration of our surroundings. The main reason for pollution is the result of the everyday lifestyle of the people on earth, this includes explosion, rapid industrialization, deforestation, and many other examples. These changes to the environment can affect the physical, chemical, and the biological characteristics of the earth as well as all living things. When there is industrialization there is urbanization not to far behind. Unhealthy environments have occurred due to the migration of the rural populations into the cities. This has led to overcrowding as well as the establishment of the slums within the city. This has caused the towns surrounding the cities to become full of smoke, fumes, and dirt which lead to foul smells throughout the

Environmental pollution is an enormous problem in the United States. Environmental pollution is a substance that is harmful or poisonous to the environment. Air pollution, water pollution, thermal pollution, and soil pollution are major types of environment pollution. Pollution is linked to some of the most deadly diseases. “Carbon monoxide is an odorless, colorless gas which is poisonous at high levels. CO bonds with hemoglobin more easily than oxygen, so that it reduces the body's ability to deliver oxygen to organs and tissues” (Neidell, 1005). Air pollution is the most harmful out them all because we inhale it every day. "Ozone (03) is a secondary air pollutant formed by nitrogen oxides and volatile organic compounds in the presence of

There are many types of pollution, some examples are ocean and air pollution. Ocean and air pollution are serious issues that has been going on for years. Until today, pollution is still occurring and still considered a threat to the environment and people. Air pollution is when enormous amount of dust and gasses combine. On the other hand, ocean pollution is when marine animals and lifestyle are being affected due to natural and human activities. There are consequences to humans and animals if these types of pollutions are not solved. It can also cause a shorter life span for the majority of the people. Pollution is a critical issue, sadly people are not wised enough to care and act upon this situation.

Pollution of the surrounding environment has accelerated dramatically after the industrial revolution, leaving a legacy faced by modern society. The primary source of such pollutions is the burning of fossil fuels, mining and smelting of metalliferous ores, municipal wastes, agrochemicals and sewage. Migration of contaminants from neighboring contaminated land to a non-contaminated sites as vapors and leachate through the soil or as dust or spread of sewage sludge, further contributes to the contamination of natural ecosystems (Khan 2005). A wide range of materials causing contamination includes heavy metals, inorganic and organic compounds, oil and tars, toxic and explosive gases, combustible and putrescible substances, hazardous wastes and

A.O. Coaker ,C.G.Achi, M.K.C. Sridhor, C.J.Donnett(2015) studied the current institutional solid waste management in a Nigerian private institution of higher learning. Using key informant as interview and personal field observations, the waste generation rate, pattern and characterization was made. It was concluded that if all the organic waste streams from the kitchens ,canteens and animal house are utilized for the bioenergy and organic fertilizer and non-biodegradables can be sold in the secondary market and considerable amount of wealth can be recovered

In order to understand how to build a solid waste facility you first must understand what solid waste is and how it impacts a community. Municipal Solid Waste (MSW) is an array of materials discarded by households, businesses, industries, and agriculture. Solid waste is not always in a solid form and can be semi-solid, liquid, and gaseous wastes. Proper disposal of these solid waste materials include municipal and industrial landfills, industrial surface impoundments, and incinerators. Through many useful disposal options waste can be handled as a reusable energy source such as with an incinerator the waste can be turned into energy. Sewage sludge and agricultural waste being applied to land surfaces as fertilizers or soil conditioners can save on disposal and increase production in farming areas. Building a sustainable waste facility can be done and it can be sustainable if managed correctly with low waste having to be placed into a landfill area.

When a waste cause threat to human health, it is considered as hazardous (RCRA, 1978). According to RCRA of USA all the wastes are solid

Pollution is the introduction of harmful substances or products into the environment. It is a major problem in America and as well as the world. Pollution not only damages the environment, but damages us also. It has cause many problems ranging from lung cancer to the greenhouse effect. It is all among us but we continue to live in our own filth. What is the reason behind this flawed logic? In this paper I will examine the problems and solutions for this issue.

What is waste? Waste is what all humans on earth throw away into their garbage bins or onto the side of the road. Everything that humans use and consume eventually turns into waste and must go somewhere. This process of using the Earth’s natural resources and then throwing them away shortly after will not be sustainable and measures must be taken to help the environment.

Pollution happens when chemicals and other outside substances leech into the ground, air and water. These pollutants contain poisons that adversely affect environments and the living animals inside of them. Although natural well being and security gatherings work to build attention to the threat contamination presents, if contamination proceeds at its present rate, the future impacts could crush to human populaces and the earth.

Although it is generally agreed that enormous quantities of solid waste are generated in Ibadan daily, the exact figures have not been determined, probably owing to the use of diverse methods of calculation. Maclaren International Ltd (1970) found that the average per capita quantity of solid waste generated was 0.37–0.5 kg/day for the traditional areas of the city and 0.53 kg/day for the newer areas. According to Egunjobi (1986), 38 million kg of solid waste was collected in the suburbs of Ibadan in 1986. The suburbs constitute about 21% of the city. On this basis, it can be estimated that 181 million kg of solid waste was generated in the city as a whole in 1986. This gives a per capita waste-generation rate of 0.31 kg/day, using the 1986 estimated population of 1.6 million for the city.
