The main affect of the activity of cement in the environment are emissions of dust and gases. The particulate pollutants can enter the dry, wet soil or hidden deposits and can undermine their physico-chemical properties (Laj and Sellegri, 2003). Therefore, contamination of cement powder has a negative effect on the physico-chemical properties and soil biological activity.  Cement production is a major
roduction The environment serves us three purposes: it’s our living space, our supply depot and our waste repository. But through human existence and activity, the environment is gradually “falling apart.” This essay aims to highlight how air pollution and climate change go hand in hand and how they both influence the global natural environment, society and all of society’s systems.. Air pollution refers to the release of harmful substances into the Earth’s atmosphere, which in turn, has detrimental effects on the natural environment. The air pollution triggers a change in climate, which will be discussed in the next paragraph. Nature and extent of the issue Air pollution has a threatening effect on the ozone layer-which is an invisible layer of gasses that protects the surface of the Earth from harmful ultra-violet radiation. The ozone layer is therefore thinning and
These are both inorganic and organic. The bulk of dewatered and digested sludge can be used as organic fertilizer or it may be burnt to produce energy. 2.4 Classification of MSW : It is classified as hazardous and non-hazardous. 1..Hazardoous waste : It is waste generated during production or other activities by the society. Hazardous waste posses a potential hazardous to human health or environment when not well managed.
How is Air pollution caused? Air pollutants mainly occur as a result of gaseous discharges from industry and motor vehicles. (1) It can be caused from both human and natural activities. Regular events that contaminate the air incorporate woodland fires, volcanic ejections, wind breakdown, soil dispersal,
Some of the things people do cause harm to the health. We cause pollution when we make our water, land, and air dirty. In this topic, you will learn what pollution is, what are different types of pollution, and how does it affect health. Pollution is anything that makes the earth dirty and unhealthy. Water, air,and land are all affected by pollution.There are different types of pollution categorized based on the part of the environment which they affect or result which the particular pollution causes.
Introduction Pollution is an unwanted change in the environment caused by the introduction of harmful materials or the production of harmful conditions (Botkin & Keller, 2014). Urban air pollution is basically the collection of pollutants created by cities (http://en.cyberdodo.com/files/cyberdodo-and-urban-pollution/1.html). Air quality in cities is the result of a complex interaction between natural and anthropogenic environmental conditions. Air pollution in cities is a serious environmental problem especially in the developing countries. The air pollution path of the urban atmosphere consists of emission and transmission of air pollutants resulting in the ambient air pollution (Mayer, 1999).
There are many problems that society faces and one problem, such as air pollution threatens societies and entire world. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossils fuels and manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and its consequences that the world must face.
ENVIRONMENTAL POLLUTION IN PAKISTAN – CASE STUDY POLLUTION: The mixture of harmful substances within air, water or soil is called pollution. Pollution can occur naturally as well as by man-made substances, naturally pollution can occur through volcanic eruptions. As the result of human activities, pollution may occur by spilling of oil, disposal of industrial waste, smoke caused by vehicles so on. Pollution is basically caused by pollutants. POLLUTANTS: Pollutants are those harmful substances that result in pollution in the environment.
A condition in which in which the quality of air is affected by the presence of chemical, biological or physical substances in the air is called air pollution. The definition of air pollution suggested that air pollution is consists of gases, liquids and solid particles, these substances when present in adequate levels for a significant time and also under specific conditions, tend to affect the human health, human welfare and also cause the damage to environmental sustainability. Air pollution causes ozone depletion, creates smog, acid rain, and other hazardous environmental phenomena. According to---, air pollution can be defined as the presences of harmful chemicals and compounds including biological origin, in the air that they become a serious health risk. In the broader sense the term air pollutants mean those chemicals that have toxic health effects and does not present in the air naturally but they released into the air by through some human activities directly or indirectly.
Hazardous waste: It is waste that is dangerous or potentially harmful to our health and environment. It includes most paints, chemicals, tires, batteries, light bulbs, electrical appliances, fluorescent lamps, aerosol spray cans, and fertilizers. These wastes are those that potentially threaten the health of people. It is as a result of this that in many countries disposal of this hazardous waste is supervised by the appropriate authority. Municipal waste: This waste refers to the everyday waste from items discarded by the public.
