Abstract:
The chemical has wide range in the environment which has contaminate our earth’s land, water and air. This chemical also shows impact environment and human health. Among this containments many comes from the industry and commercial area like roads, parking, oil and chemical spills and storm drains like non point sources. The waste water treatment plants and sewage system also produces chemical containments in the environment. In the ecosystem food chain some containment entered by breakdown and accumulating. The containment accumulated by fish or any other wildlife has been eaten by human and thus it enters into the food chain system. The environmental pollution refers to unwanted or undesirable change in the chemical, physical and biological characters of water, air and soil. It has harmful for living organisms. The noise, heat or light are the chemical substance or energy form of pollution. A contaminate are enters into the body of human by four main route like inhalation, injection, ingestion and absorbed by the skin and eyes. A contaminate substance occurs by absorption via respiratory tract, and it absorbed into blood stream and distributed into throughout of body. The chemicals inhaled into the body in the form of vapors, mists, fumes, fine dust and as aerosols. The symptoms of this chemicals occur through inhalation include eyes, nose and throat irritation. It also shows the symptoms like coughing, headache, dizziness, difficulty in breathing, confusion and collapse. The mixture of many chemical species occurs in air borne particulate so it is not single particle of pollutant. It has solid core with liquid coating shows the complex mixture of aerosols contain liquid small drops and dry solid fragments and solid mixture. It has different in size, shape and chemical composition. It found in earth’s crust from, organic compounds, element of carbon, inorganic ion and metallic compounds. The air quality regulatory the air borne particle defined by his diameter. In the environment many pollutants has affect on human health and also cause different environmental problems like global warming, climate change and acid rain formation. The common surface water and ground water pollutants on lands are organic matter, bacteria, industrial waste, hydrocarbons, agrochemicals, pesticides and household products. The pollutants on the earth occur everywhere it can found in water that we drinks, it occur in air that we breathe and it also found in the food that we can it, these pollutant takes toll on our health. In the year 2015 pollution estimated about nine millions deaths worldwide , the malaria, tuberculosis and AIDS like diseases combined together but pollution has shows three time more deaths. This type of dangerous effect of chemicals condiments occur on the human health
