1. INTRODUCTION: The significance of environmental factors to the health and well-being of human populations’ is increasingly apparent. Environment pollution is a worldwide problem and its potential to influence the health of human populations is great. Pollution reaches its most serious proportions in the densely settled urban-industrial centers of the more developed countries . In poor countries of the world more than 80% polluted water have been used for irrigation with only seventy to eighty percent food and living security in industrial urban and semi urban areas.
. Industry, clustered in urban and semi-urban areas surrounded by densely populated, low-income localities, continues to pollute the environment with impunity. Over the last three decades there has been increasing global concern over the public health impacts attributed to environmental pollution, Human exposure to pollution is believed to be more intense now than at any other time in human existence.
Pollution can be made by human activity and by natural forces as well. Selfish private enterprise and their lack of awareness of public well-being and social costs and natural disasters e.g. volcanic ash from Iceland are the one of the main reason of pollution. British Airways expresses their concern about environment in their general goal 'to be a good neighbor, concerned for the community and the environment. This implies that, businesses now adopted this responsibility as part of their overall business strategy which should match their broader business goals. At present, the adoption of environmental auditing in any economic sector is voluntary but future legislation could well make it mandatory. posit that pollution control program evolves as a nationwide fixed cost-sharing effort relying upon voluntary participation. Interestingly, Goodall refers tourism as the potential to damage the environment.
There is no doubt that excessive levels of pollution are causing a lot of damage to human & animal health, plants & trees including tropical rainforests, as well as the wider environment.

Environmental pollution is tangled with the unsustainable anthropogenic activities, resulting in substantial public health problems.

Environmental health problems are not simply a conglomerate of concerns about Radiological health, water and wastewater treatment, air pollution control, solid waste disposal, occupational health, etc made attempt to detail many of the specific environmental health problems which confront contemporary man.

1.1 Air Pollution The air we breathe is an essential ingredient for our wellbeing and a healthy life.
Unfortunately polluted air is common throughout the world specially in developed countries from 1960s. South of Poland, Ukraine, China, and Pakistan even famous crowded cities and countries are facing air pollution. Polluted air contains one, or more, hazardous substance, pollutant, or contaminant that creates a hazard to general health . The main pollutants found in the air we breathe include, particulate matter, lead, ground-level ozone, heavy metals, sulphur dioxide, benzene, carbon monoxide and nitrogen dioxide. Air pollution in cities causes a shorter lifespan for city dwellers . Holland et al, illustrated that British scientists concluded that particulate and related air pollution at high levels pose hazards to human health.
According to Mishra rapid growth in urban population, increasing industrialization, and rising demands for energy and motor vehicles are the worsening air pollution levels. He added other factors, such as poor environmental regulation, less efficient technology of production, congested roads, and age and poor maintenance of vehicles, also add to the problem. He further added that air pollution is caused of ill health and death by natural and man-made sources, major man-made sources of ambient air pollution include tobacco smoke, combustion of solid fuels for cooking, heating, home cleaning agents, insecticides industries, automobiles, power generation, poor environmental regulation, less efficient technology of production, congested roads, and age and poor maintenance of vehicles. The natural sources include incinerators and waste disposals, forest and agricultural fires. 1.2 Water pollution The water we drink are essential ingredients for our wellbeing and a healthy life.
Unfortunately polluted water and air are common throughout the world. The WHO states that one sixth of the world’s population, approximately 1.1 billion people do not have access to safe water and 2.4 billion lack basic sanitation . Polluted water consists of Industrial discharged effluents, sewage water, rain water pollution and polluted by agriculture or households cause damage to human health or the environment. This water pollution affects the health and quality of soils and vegetation. Some water pollution effects are recognized immediately, whereas others don’t show up for months or years. Estimation indicates that more than fifty countries of the world with an area of twenty million hectares area are treated with polluted or partially treated polluted water including parts of all continents and this poor quality water causes health hazard and death of human being, aquatic life and also disturbs the production of different crops. In fact, the effects of water pollution are said to be the leading cause of death for humans across the globe, moreover, water pollution affects our oceans, lakes, rivers, and drinking water, making it a widespread and global concern. A drinking water contained a fluoride content ranging from 5.26 to 26.32 milligrams per liter and this is too high as compared to the World Health Organization’s standard of 0.6 to 1.7 milligram per liter. According to
Ashraf et al (2010), In present scenario due to industrialization and increased population, the drains of Pakistan carry the industrial and municipal effluents that are ultimately carried that polluted water to the canals and rivers. The untreated -industrial and municipal wastes have created multiple environmental hazards for mankind, irrigation, drinking and sustenance of aquatic life. The drainage water contains heavy metals in addition to biological contaminations. This water pollution infected our food in addition to groundwater contamination when used to irrigate crops.
Pakistani cities are facing tribulations of urban congestion, deteriorating air and water quality and waste management while the rural areas are witnessing rapid deforestation, biodiversity and habitat loss, crop failure, desertification, land degradation, clean drinking water, noise pollution, sanitation . 1.3 Land/ Solid waste Pollution Improper management of solid waste is one of the main causes of environmental pollution
. Land pollution is one of the major forms of environmental catastrophe our world is facing today. As Bulgaria and the Slovak Republic, heavy metal industries have produced wastes that are deposited into landfills without special precautions posit that Approximately half of the population lives in the vicinity of waste sites that do not conform to contemporary standards in Romania. Czech Republic’s coal and uranium mines have produced serious pollution problems, and much of the solid industrial waste containing heavy metals is disposed of, without pretreatment, in open dumps
