The using of asbestos material is banned in several countries, because of several cases have founded people sick because of asbestos effect. Since asbestos related disease has been identified by medical profession in the late 1920s, workers compensation cases were filed and resolved in secrecy, with a flood of litigation starting in the United States in the 1970s. Mainly in individually brought cases for terminal cases of asbestosis and cancers. Some countries that already banned using of asbestos material as follows: International law Australia Brazil Canada France India Italy Japan South Korea New Zealand United Kingdom United States And some diseases have known causes by asbestos as below: Asbestosis - A lung disease first found in textile workers, asbestosis is a scarring of the lung tissue from an acid produced by the body's attempt to dissolve the fibers. The scarring may eventually become so severe that the lungs can no longer function. The latency period ...

POPs is pertinent organic chemicals, mean many chemicals include on this cathegory. General people will don't know this chemical because this kind of chemical is not include in the study, I mean cathegorized chemical in such kind like that. In lecture usually only familiar with kind of chemical like organic or unorganic chemicals, or include on metal or non metal this cathegorized is just for differentiate when study about metal characteristic. So POPs will be a new knowledge for general student if they never read this knowledge, they will don't understand this. POPs chemical is forbiden include on other chemical or use in industry to help the process, because this pollutant will retain in the human body if can enter the body through many kind of ways. This pertinent chemicals pollutant then can make disseases of disturbance body organ work like kidney, lung, hearth, brain, pancreas and many others body organ. Stockholm convension about POPs have been perform three tim...

Today I follow a workshop of POPs that part of Stockholm covention in Jakarta arrange by Ministry of environtment. POPs is not about music or trending model, this is a Persistent organic pollutants (POPs) that are chemical substances that persist in the environment, bioaccumulate through the food web, and pose a risk of causing adverse effects to human health and the environment. This group of priority pollutants consists of pesticides (such as DDT), industrial chemicals (such as polychlorinated biphenyls, PCBs) and unintentional by-products of industrial processes (such as dioxins and furans).  Persistent Organic Pollutants are transported across international boundaries far from their sources, even to regions where they have never been used or produced. The ecosystems and indigenous people of the Arctic are particularly at risk because of the long-range environmental transportation and bio-magnification of these substances. Consequently, persistent organic pollutants pose a th...

We know that Sulfur Dioxide is poisonouos gasses but why this substance can found in food. Is this good to eat? Sulfur dioxide is one of sulfite, a preservative whose name might be more familiar, that is why this substance can be available inside the food usually preservative food. A small amount of sulfite can wreak health havoc of you're sensitive to it. If we have asthma, sulfite sensitivity or sulfite allergy, eating dried fruits might cause serious health problems, including breathing problems. Dried fruits are among the food highest in sulfites, with raisins and prunes containing between 500 to 2000 ppm, compare to wine that may contain sulfites only 20 to 350 ppm. As the regulation of US Food and Drug Administration mandates that foods containing more than 10 ppm of sulfites must list this information on the food label. Each countries have different standard of sulfite contain in food, Australian government limits sulfite in food to 3000 ppm, while British government...

Legislation about asbestos in each country already settle, and each country have their own regulation about using asbestos. To enforce of the compliance to the regulation, some country using many aid like OHS enforcement and safety officer. The Asbestos-related Claims (Management of Commonwealth Liabilities) Act 2005 provides for Comcare to assume and manage the common law asbestos-related conditions liabilities of the Australian Government and, with certain exceptions, its agencies and controlled companies. Type of enforcement to comply with this regulation through several ways such as follows. There are a range of enforcement actions that may be applied by Comcare when OHS legislative obligations are not met by duty holders. All employers, employees and other parties who have duties under the Occupational Health and Safety Act 1991 (OHS Act) are subject to the compliance, enforcement and penalty provisions of the OHS Act. The maximum penalty for criminal breaches of the OH...

The ability of atoms of an element to lone electrons is measured by the various ionization potentials characterizing that element. Conversly, the ability to gain electrons is measured by the electrons afinity or the electronegativity. It would follow, therefore, that ionic linkages resulting from electron transfer about occur most commonly between elements with comparatively low ionization potentials and elements with comparatively high electron affinities.

Electroplating is a process that convert a metal solution into the solid in other metal surface using direct electric current. The solution is made can conduct electric current, if the solution can't conduct electric current can add some acid or base solution that can conduct electric current. Metal solution will exist in positive ion form which transfer to the negative pole of the electrode because every charge molecule will go into the opposite of the electrode. For example in Chrome Plating Process , the chemical use chromic acid will can dissolve in water. To make this solution more conduct of electric current, into the solution add with sulfuric acid. The composition of chromium bath will vary depend on the goal of end product will formed. For Bright Plating use this formulation: The basic formulation of 100:1 chromic acid/sulphuric acid proportions: Chromic acid crystals = 33 oz. (936 grams)  Sulphuric acid fluid = .33 oz. (9.36 millilitre)  Distilled...
