While there are natural sources for all of these species‚ the concentrations of chlorine and bromine have increased markedly in recent years due to the release of large

air pollutant that is released is sulphur dioxide and nitrogen oxides. This is because when coal and fuels obtained from crude oil are burned‚ sulpur and nitrogen is released into the atmosphere‚ which is eventually joint with the oxygen in the air to produce sulfur dioxide and nitrogen oxide. When these gases are emitted in sufficient quantities‚ it reacts with the water and oxygen in the atmosphere to produce sulfuric acid and nitric acid which will mix with rainwater in clouds and form acidic solutions

Alternate Nostril Breathing Versus Normal Breathing After conducting a mini “study” of whether alternate nostril breathing helps people with sleep issues as opposed to normal breathing at bed time‚ it was concluded that‚ yes‚ alternate nostril breathing at bed time does help to relax a person and put them in a more sound sleep than normal breathing. In the personal study conducted‚ three nights were done under normal breathing circumstances and three nights with the alternate nostril breathing

nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels‚ such as coal‚ natural gas‚ and oil‚ and from certain kinds of manufacturing. Sulfur dioxide and nitrogen oxides react with water and other chemicals in the air to form sulfuric acid‚ nitric acid‚ and other pollutants. These acid pollutants reach high into the atmosphere‚ travel with the wind for hundreds of miles‚ and eventually

nitrogen oxides (NOx) are released into the atmosphere‚ undergo chemical transformations and are absorbed by water droplets in clouds. The term "acid rain" is used more generally to include all forms of acid deposition. That Acid rain is one of the most dangerous man-made disasters which forms environmental threats is a fact that makes each individual concerns about its stages‚ causes and effects. The first stage of acid rain formation is produced when sulfur dioxide (SO2) and nitrogen oxides (NOx)

such as nitrogen and sulfur oxides‚ that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. The acid deposition is occurs in two way which is wet deposition and dry deposition. It can have harmful effects on plants‚ aquatic animals‚ and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide‚ which react in the atmosphere

What are the major differences between gestational hypertension‚ preeclampsia and eclampsia? Pregnancy-induced hypertension is a rise in blood pressure‚ without proteinuria‚ during the second half of pregnancy. Pre-eclampsia is a multisystem disorder‚ unique to pregnancy‚ that is usually associated with raised blood pressure and proteinuria. It rarely presents before 20 weeks’ gestation. Eclampsia is one or more convulsions in association with the syndrome of pre-eclampsia. (Duley‚ L. (2008)
