Environmental chemistry is the study of chemical processes occurring in the environment which are impacted by humankind's activities

Environmental chemistry is the study of chemical processes occurring in the environment which are impacted by humankind's activities. These impacts may be felt on a local scale, through the presence of urban cities' air pollutants or toxic substances arising from a chemical waste site, or on a global scale, through depletion of stratospheric ozone or global warming. The term contaminant is often used interchangeably with pollutant, which is a substance that has a detrimental impact on the surrounding environment.

Human impact on the environment. Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse.

The damaging effect on the environment is caused b.There is the danger that in the long run the damage may not be recovered. Other man-made chemicals, apart from CFCs, are eating ozone molecules. Among them are halon gases used in fire extinguishers, aerosols, and refrigerators, and two compounds widely used as solvents: methyl chloroform and carbon tetrachloride. Their combined reaction on the ozone layer is devastating, allowing ultraviolet rays from the sun, known as UV-Bs, to bombard the earth.

nuclear, biological, and chemical environment - Environments in which there is deliberate or accidental .

Coffee and the environment - Is socially responsible coffee helping America take one sip towards a healthier environment? Changes in how coffee plants are grown have resulted in effects on the environment.

Man and the Environment were created to interact with each other on balance basis. Also, pollutants of domestic waste, chemical waste, and animal droppings all cause environmental degradation. Whiles the natural environment is to create a fair decent shelter and to provide food supplements including economic resources of gold, oil, and so on, man on other hand is suppose to care and protect the environment from destruction. Directly or indirectly, the physical environment has inevitably influenced man. During the last 100 years, man has exceeded the powerful natural forces that have shaped the shape of the earth's surface.

In the early 1960s, an interest in women and their connection with the environment was sparked, largely by a book written by Esther Boserup entitled Woman's Role in Economic Development. Starting in the 1980s, policy makers and governments became more mindful of the connection between the environment and gender issues. Changes began to be made regarding natural resource and environmental management with the specific role of women in mind.

About 200 years ago man lived in greater harmony with his environment because industry was not developed. Modern man consumes a far greater amount of oxygen to support fires, power plants and chemical processes. Prehistoric man withdrew from atmosphere only the oxygen he required for respiration. Today the situation is quite different. The carbon dioxide produced by technological processes has greatly changed the carbon dioxide concentration in the atmosphere

Speaking of the natural environment, we use the term ‘ecology’. This word was introduced in 1869 by German biologist Ernst Haeckel (1834-1919) for the science studying the relationship of organisms with their environment. This word came from Greek ‘oikoş’ which means ‘home’.

Speaking of the natural environment, we use the term ‘ecology’. The idea of home includes our whole planet, its population, nature, animals, birds, fish, insects and all other living beings and even the atmosphere around our planet. For a long time ecological problems were considered only in the context of biology.

There are some 30,000 man-made chemicals currently in use. Although the European Union already has strict laws govern-ing their use, we know very little about many of the health risks they pose. So we need a reliable way to assess and reduce their impact on human health while managing their use.
