Hello friends Glam thank you to visit Vblagmvn. olives in brine We are two students from the Department of Geology and Hdfmvn of this blog is primarily to help your loved ones to answer the questions in the second place to serve the science of geology and geological beautiful olives in brine Ast.amydvarym us to do in this matter.

The effects of arsenic on human health
Arsenic (Greek olives in brine arsenikon means Arpymnt yellow) for the first time by "Albertus Magnus" was established in 1250 and in 1649 "Young Schroeder" published two ways of preparing olives in brine arsenic. As a result of the heat Rsvpyzyt (arsenic ore) which is called Miss Pickel, of iron sulfide is removed. The elements of heavy metal, which is highly toxic in soil, water and air, some of them are mentioned in the following table. The use of insecticides, olives in brine herbicides containing arsenic mean arsenic in the environment increases, leading to the entry of toxic material olives in brine into the food chain and from there to the human body and endanger human health.
Osteoporosis and bone fragility

The three form a metallic element, trivalent and hexavalent five there. The cytotoxicity of each form of arsenic is rapidly excreted from the body and the degree of aggregation depends on the cellular context. The toxicity of arsenic is rapidly excreted from the body and accumulate in tissues, cell temperature olives in brine dependent. Organic arsenic is less cytotoxicity against inorganic arsenic tend to build bonds with proteins containing SH groups and therefore are more toxic.
But this toxic element olives in brine in many cases, health and human lives are endangered and causes of liver disease, olives in brine skin and lung cancer, and in some cases, including the likes, the continuity of human life thanks olives in brine to wound healing, treatment olives in brine of plague, acute leukemia, malaria, syphilis, rheumatism Trypanvzvmyazys and cited.
According to the WHO standard for arsenic olives in brine in drinking water in 1993, allowance is less than 0.01 mg per liter. But clearly seen that the inorganic arsenic in drinking olives in brine water spreads in different ways, arsenite and arsenate 3 Capacity 5 more capacity can be found in drinking water. Water arsenic poisoning can be caused by the passage of water from the rocks rich in arsenic and arsenic in soil stratum water or industrial waste streams can be achieved. The contaminated olives in brine water by plants and animals, or directly consumed by humans and enter the human food chain and endanger its health. olives in brine For example, the most common liver disease in the Japanese fishing due to arsenic-contaminated fish consumption has occurred.
As a result of disturbances in the synthesis olives in brine of DNA and RNA, which is a result olives in brine of the cancer. Exceptional increase in birth, low birth weight, birth and stillbirth due to anomalous arsenic compounds was observed. Chronic arsenic poisoning after a long period (5 to 20 days) exposure to arsenic poisoning caused immediate symptoms that include nausea, pain in the gastrointestinal tract and diarrhea. Exposure to arsenic, even at low levels (0.05 mg) increased risk of skin cancer, lung, urinary tract, bladder and kidney increases. It also causes skin changes (dark or light spots on the skin) thickness swell or yellowish skin (keratosis), adverse effects on the nervous olives in brine system (tremor and pain in the head) of the other toxic effects of arsenic is.
As breathing vapors olives in brine causes respiratory tract infections such as bronchitis, laryngitis, and swelling of the mucous membranes. As seen in the effects on gastrointestinal symptoms tingling lips, swallowing, pain, thirst, colic, nausea and diarrhea is. Continue to cause anemia and reduces white blood cells and red blood cells caused inhibition of the synthesis of high levels of arsenic can cause weakness in the bone marrow.
Taiwan is the only drinking water arsenic poisoning Rsynkvzys disease (vascular olives in brine damage) has been reported as a result of poor circulation in the hands and feet and continued progression of the disease occurs in the bone-and-black become Gangrene followed which leads to muscle cuts. According to the World Health Organization, the prevalence of the disease, gangrene in China.
The researchers found that 7/7% of the participants olives in brine had type II diabetes after taking into account other risk factors, it was found that the amount of arsenic in urine 26Drsd diabetes than those without diabetes.
These studies showed that more than 20 percent of participants with the highest levels of arsenic (5.16 micrograms per liter) in their urine were 3.6 percent higher than those with the lowest levels of arsenic (3 micrograms per liter) had urine were diagnosed with Type II diabetes.
The researchers concluded that arsenic may be genetic factors that affect insulin sensitivity and other processes involved or cellular damage associated with oxygen, inflammation and cell death that is associated with diabetes, have a role.
Measurement of arsenic in water is done in different ways, the most important of these methods using atomic absorption spectrometry with hydride, using iodometry by silver diethyldithiocarbamate spectrophotometric method Photo Ytv carbamate m. If the amount of arsenic in water was higher than the standard can be found through the
