How We Use Chlorine

Monday, January 24th, 2011

The chemical element chlorine is a halogen that is used to make a wide range of products that many of us use every day. Chlorine is pronounced as KLOR-een or as KLOR-in and it has many uses in the world today. It is used in commercial manufacturing of chlorides, polymers, pesticides, chlorinated solvents, refrigerants and synthetic rubbers. In many cases chlorine is put together with other elements to help create different sorts of products that we all use.  It can be used in liquid form and as a compressed gas.

Chlorine is not found naturally in water such as streams, lakes, rivers, ponds and oceans.  However, one of the main uses of chlorine is using it to disinfect water in pools, sewage and even drinking water.  Chlorine is added to drinking water to kill harmful bacteria. If you want to sanitize water then using chlorine is the most effective way of doing it.  Chlorine is the most commonly used drinking water disinfectant and it is also commonly used as an antiseptic.

Governments will often use chlorine to disinfect water for use by the general public as it kills the microorganisms that can cause diseases. It can kill potentially fatal diseases like legionnaire’s disease that is common in water sources. Chlorine is added to drinking water as either a gas or after having been already dissolved in water. Adding a toxic gas to water might sound incredibly dangerous to your health but small doses of chlorine are harmless.

When it comes to swimming pools and spas, chlorine is by far the most used of all the swimming pool chemicals available. Chlorine is used to disinfect swimming pools to prevent algae and bacteria from building up in the water. Most swimming pool chemicals that contain chlorine also include a mix of acids and alkalines.  People who use chlorine-based laundry bleach and swimming pool chemicals are not exposed to chlorine itself.  There is a danger of being exposed to chlorine gas if you make these mistakes with swimming pool chemicals. Individuals may also be exposed to it if swimming pool chemicals are accidentally mixed with acids or too much sodium hypochlorite is added to the water over a short period of time.  If enough acid is added to lower the pH of the hypochlorite solution to below 4, chlorine gas will be released.

Algae are adapted to a given environment, just as other organisms are.  Algae often makes natural toxins, that are released when the algae dies and starts breaking down in the water. Algae can be smelly and unsightly as well as being toxic to humans, pets, and livestock.  The algae can support the greater biomass of the next trophic level only because they can reproduce as fast as they are eaten.  There are a number of different types of algae, these are called brown, red and blue green algae. They are named after the different colours they are. Blue-green algae can be suspended at various depths in the water, and their location depends on a number of factors.  Most algae love a warm environment with shallow, undisturbed water that will get a lot of light from the sun.  Blue-green algae can become a nuisance species when adequate nutrients and favorable environmental conditions are present.

Is swimming pool chemical Simazine dangerous?

Sunday, May 31st, 2009

The chemical Simazine, which is used in products to clean swimming pools and stop the growth of Algae is recieving calls to be made illegal. Simazine has been banned in the United States since 1994 after it showed it had links to causing cancer, but is still used in Australia. A report from the Australian pesticides and veterinary medicines authority (APAVM) makes claims that the levels of the chemical are far higher than the recommended allowed daily intake (ADI) health limit.

While the report didnt show that children exposed to the chemical have any lasting health problems, supporters of the ban are claiming with the levels over the ADI, the effects in later life for children could be dangerous. William Bliss, whose company Wobelea manufacturers products that contain the chemical Simazine, claim that people are over reacting. ‘For arguments sake, you would have to drink all the water in an Olympic pool, say 500,000 litres, to get anywhere near a toxic dose’.’

The investigation will determine if any new information has come to light reguarding the effects of the chemical, but while this is happening products containing Simazine will still be made available, which has angered campaigners. The chemical is banned in the United states and not used at all in European countries, which asks the question why are questionable swimmming pool chemicals still used in Australia? If the product is banned then the Australian government has said that it will move to ban the chemical and pull products containing the drug from the public domain.

Last month in Tasmania, there was panic in the local area after traces of this chemical and Altrazine were found in the supplies of drinking water. Though the levels of the chemicals found in the water sources has been said to be minute, there should not be any in drinking water sources at all.
