Effects and impacts as a result of exposure to mercury

Effects and impacts as a result of exposure to mercury
The reason why the mercury is one of the health problems due to mercury memliliki affinity ( holding capacity ) specific to the brain and nerve tissue so that exposure and intake of these substances can cause damage at the site tersebut.Terapi pengekatan ( chelating agent is a type of chemical that has a special affinity to the metal ) is necessary because the chelating has a "pull " stronger on the brain and nervous tissue than metilmerkuri.Oleh Therefore , if the poisoning successfully detected early , treatment can be conducted successfully .
The effect and impact caused by exposure to mercury is
1 ) Effect Physiology
The effects of mercury toxicity , especially in the CNS and kidneys where mercury accumulates . Duration , intensity and track as well as the form of mercury exposure affects the system what is effected . The main organs affected by the chronic exposure to mercury and organomerkuri element is the CNS , being the salt of mercury causes damage to the kidneys .
Being on acute poisoning inhaled mercury element have no effect on the respiratory system , is being ingested mercury salts have no effect on cardiovascular pencernaan.Sistem channel is a secondary effect .
2 ) Effects of Neurology
Central nervous system is the primary result of pemejanan element Hg vapor and MeHg . Senyawaini shape penetrate blood brain barrier and can cause irreversible brain damage .
MeHg ingestiakan slow CNS symptoms that may not manives after several months of exposure , and the first symptoms are often non -specific , such as malaes , blurred vision , ataupendengaran lost .
3 ) Effects On Kidney
After the inorganic salt or ingested phenylmercury accumulation will occur that will result in kidney tubular epithelial permiabelitas rise . Exposure to mercury vapor or mercury salts can result in nephrotic syndrome or protein noble , akuta tubular necrosis and renal failure occurs .
4 ) Effect On Growth
A study of MeHg levels in the blood of newborns in comparison with the mother's blood has a significant connection . Babies born to mothers in eating foods containing mercury can suffer brain damage MeHg manifestations :
a) Mental Retardation
b ) Deaf
c ) shrinkage of the visual field
d ) Microcephaly
e ) Ataxia
f ) Blind
g ) Swallowing disorders
5 ) Other Securities
Effects on the respiratory and digestive systems of food poisoning can occur at akut.Inhalasi of elemental mercury can lead to severe damage of the lung tissue , the outopsi found dilatation of the right ventricle resulting in failure of the respiratory system in children Hg.Gastritis steam inhalation and ulcers on the mucosa intestine can occur as a result of ingestion of inorganic salts . Liver damage has also been reported in salt poisoning mercury.Kenaikan or drop in blood pressure has been linked with exposure elemental mercury.Aberasi chromosome found in some workers with mercury

In Mercury Pollution in Water and Environment

In Mercury Pollution in Water and Environment
The use of mercury in industries often cause environmental pollution , either through waste water and air through the ventilation system . Mercury discharged into the river , beach , or body of water around the industry - the industry can then contaminate fish and other water creatures and plants including algae air.Selanjutnya small fish and other water creatures may be eaten by fish or other aquatic animals and larger animals or enter through the gills .
Shells can also mengumpulkanmerkuri in rumahnya.Ikan - fish and animals are then consumed by humans so that humans can collect his preformance mercury . Several studies have shown that all fish are not directly contaminated with mercury during its growth still contains mercury in the body at low concentrations , ie from 0.005 to 0.075 ppm .

        
Toxicity and Biological Methylation
Poisoning has occurred and is often quite serious poisoning because it can lead to death and disability seumuur living in the tables below shows the five mercury poisoning that claimed quite a lot and going on until 1968 . Poisoning - poisoning is mainly caused by the consumption of mercury-contaminated fish or consumption of grain treated with mercury .

Although the mechanisms of mercury poisoning in the body is not clear , but some things about the toxicity of mercury can be explained as follows :
1 ) All the components of sufficient quantities of toxic mercury in the body .
2 ) Each component has different characteristics of mercury in their toxicity , accumulation or distribution collection and retention time in the body .
3 ) biological transformation can occur in the environment or in the body where the mercury component is converted from one form into another form .
4 ) The effect of mercury in the body because it can inhibit the alleged action of the enzyme and cause cell damage due to the ability of mercury to be bound by sulfur -containing groups in the molecules present in the enzyme and the cell wall . This situation resulted in inhibition of enzyme activity and chemical reactions are catalyzed by enzymes in the body . The properties of the membrane of the cell wall will be damaged due to the binding of mercury so that normal activities will be disrupted .
5 ) Damage to the body caused by mercury is usually permanent , and has yet to be cured .
People - people who have potential exposure to mercury .
According to the Ministry of Health of Health , 1996 , people who have potential exposure to mercury ( Hg ) are:
1 ) Workers maker of chlorine and soda coustic
2 ) Factory worker batrey , fluorescent lamps , mercury lamps .
3 ) Metelurgis
4 ) miner and processor of HGS , gold , silver , copper and zinc
5 ) factory paint and pigment
6 ) Painters
7 ) Rollers paper
8 ) factory workers as well as spraying of pesticides and fungicides / user
9 ) Pharmaceutical Company
10 ) Plumbers
11 ) cosmetic products
12 ) Dental oersonel
13 ) Electroplators
14 ) Plant explosives
15 ) wool factory workers and tanners
16 ) machine operator sharpener
17 ) Ink Factory
18 ) Workers in hazardous waste site
19 ) Officers laboratory .
Fetuses , infants and children have a high risk for acquiring impact MeHG.MeHG Exposure can cross the placenta , nervous system sensitive to Hg poisoning . Due to high levels of MeHg in breast milk so nursing infants may be exposed . The workers were using mercury or mercury-containing products , and their family members may have a higher risk to mercury exposure , fetuses and children are at highest risk of exposure to the effects of methyl Hg .

Intestinal worms ( Ascariasis )

Intestinal worms ( Ascariasis )
Ascaris lumbricoides worms known as stomach disease is called Ascariasis , usually it can infect several channels associated with the gastrointestinal tract such as the pancreatic duct and bile duct . It also can infect the appendix as well . Usual treatment is done if the gastrointestinal tract is still in use that are crippling worms obat2an like pyrantel pamoate . Pyrantel pamoate will cause interference with the movement of the worm so easily removed through the anus . It can also be used piperazine And ideally combined with the hope laxantif like minyak2 telur2 also issued along with the adult worm worms .
I. Definition
Ascariasis is a disease caused by Ascaris lumbricoides pleh . Presvalensi disease is still quite high because his Cacina cause of this disease in the tropics , is cosmopolitan . ( everywhere ) . Transmission through the worm attached to the vegetables and the food is not clean contaminated worm eggs .
III . environmental component in disease transmission
Ascaris ( intestinal worms ) spread throughout the world , with the greatest frequency is in the humid tropical countries where prevalence rates sometimes reach above 50 % . The prevalence and intensity of infection are highest in children between the ages of 3 and 8 years . In the United States , Ascaris commonly found among immigrants from developing countries . Transmission occurs by swallowing the eggs are fertile of soil contaminated with human feces or from the raw product contaminated with soil containing worm eggs . Transmission does not occur directly from person to person or from fresh feces to people . Transmission occurs most frequently around the house , where the children , in the absence of sanitary latrine facilities , contaminating the area ; infections in children mostly due to ingesting contaminated soil . Contaminated soil helminth eggs can be carried away because it attaches to the foot or footwear into the house , transmission can also occur through the dust .
Eggs reach the ground through the feces , and developing ( embrionasi ) ; at summer temperatures they become infective after 2-3 weeks and then remain infective for several months or several years in soil under suitable conditions . Embrionasi eggs hatch in the intestinal lumen ingested , the larvae penetrate the intestinal wall and reach the lungs through the circulatory system . The larvae grow and develop in the lungs ; 9-10 days after infection they enter the alveoli , trachea and swallowed penetrate to reach the small intestine 14-20 days after infection , in the small intestine they grow into adults , mate and begin laying eggs 45-60 days after ingesting eggs terembrionasi .
IV . period of communicability
Fertile adult female worms live in the intestines . Normal lifespan of adult worms was 12 months ; could be more than a maximum of 24 months , female worms can produce more than 200,000 eggs a day . In conditions in which eggs can survive in the soil for many years .
WAYS Pembrantasan Ascaris LUMBRICOIDE ( CACINGGELANG )
A. Preventive measures :
1 . Educate the public to use the toilet facilities that meet the health requirements .
2 . Provide adequate facilities for proper sewage disposal and prevent contamination of the soil in the area immediately adjacent to the home , especially where children play .
3 . In rural areas , create a public latrine construction in such a way so as to prevent the spread of Ascaris eggs by running water, wind , and others . Compost made ​​from human excrement for use as fertilizer may not kill all the eggs .
4 . Push behave hygienic habits in children , for example, teach them to wash their hands before eating and handling food .
5 . In endemic areas , keeping the food is always closed so as not exposed to dust and dirt . The food that has fallen to the floor should not be eaten unless they have been washed or heated .
B. Treatment
specific : mebendazole ( Vermox ® ) and albendazole ( Zentel ® ) ( also effective against Trichuris trichiura and hookworm , trichuriasis and hookworm see ) . Both of these drugs are contraindicated during pregnancy for granted . Deviations Papers worms Disease ( Ascariasis ) migration of ascaris worms have been reported after administration of mebendazole therapy ; but it may also occur with other drugs or therapies migration irregularities may also occur spontaneously in severe infections . Pyrantel pamoate ( Antiminth ® , Combantrin ® ) is also effective in a single dose given ( these drugs may also be used for hookworm , but not for T. trichiura ) .
C. Control of patient , contacts and the immediate environment :
1 . Report to local health authority : official report is usually not done , Class 5 ( see petenteng Reporting) .
2 . Concurrent disinfection : the sewerage sanitary latrines .
3 . Investigation of contacts and source of infection : search and find other people who need diberpengobatan . Note the polluted environment is the source of infection , especially around the homes of people .
4 . Epidemic measures : do the prevalence survey in highly endemic areas , provide public education on environmental sanitation and personal hygiene and provide treatment facilities

Epidemiological causal Primary and secondary causes in the process of disease incidence .

Epidemiological causal Primary and secondary causes in the process of disease incidence .
Causal cause of primary
This element is considered as a causal factor causal elements that cause the disease can be divided into five major groups , namely :

    
biological causes elements : all elements of the cause of the group classified as living organisms including microorganisms that can cause disruption of Patience .
    
cause of nutritional elements : all elements of causes including goals . nutritional substances that can cause disturbances of Patience
    
cause of the chemical elements : all elements in the form of chemical compounds that can cause disruption of Patience
    
Causative agent of physics : all elements yng can cause disease through physical processes
    
Causative agent psikhis : all elements related to the incidence of mental illness and social disruption
Secondary causes of Causal
Secondary ØPenyebab an enhancer in the incidence of different causes of disease incidence of each disease generally greatly influenced by the various elements that interact with the elements of the cause and participate in the process of cause and effect

    
Elements of host ( Host )
Elements of host ( humans ) can be divided into two main groups namely nature , the nature of which are closely related to humans as biological beings and human nature as social beings

    
Humans as biological beings ,
        
Age , sex , race and ancestry
        
The anatomical shape of the body
        
Physiological function and physiology of the body
        
The state of immunity and the body's reaction to the various elements of the outside or from within the body itself
        
The ability of the host to cause the interaction between biological and nutritional status in general health status

    
Environmental Elements
        
Elements of the environment plays a fairly important in determining the interaction process between the host with the causative agent in the disease process
        
Broadly speaking ingkungan elements can be divided into 3 parts , namely the biological environment , the physical environment and the social environment
