Arsenic is the highly poisonous inorganic contaminants originating from either earth crust or anthropogenic activities. Arsenic caused both are severe and chronic health effects on the human body, such as respiratory, pulmonary, cardiovascular, gastrointestinal, dermal changes (pigmentation, hyperkeratoses, and ulceration), immunologic, hematological, genotoxic, mutagenetic, hepatic, renal and carcinogenic effect (kazoo T Suzuki et al 2002). According to the United States Environmental Protection Agency (US EPA) maximum arsenic contaminant level (MCL) is now decrease 50 to 10 micrograms per liter. [US EPA. Minor clarification of National Primary Drinking Water Regulation for arsenic] .Due to adverse health effect of arsenic, in the last few
Oxidation 2. Hydrolysis by esterases 3. Transfer of metabolites to glutathione Elimination of metabolites occurs mainly in the urine and feces. Eighty to 90% of most compounds are eliminated within 48 hours. 2 A small proportion of OP compounds and their active forms are eliminated unchanged in urine.
it's recognized as malignant neoplastic disease and chronic exposure to arsenic leads to a good vary of adverse health effects looking onthe physical–chemical conditions of the setting, some arsenic compounds are often simply solubilized in water and brought up by microorganisms, leading to high levels of bioavailability. the foremost notable case wasdetermined in Asian nation and Bangladesh wherever over fifty million individuals were exposed to extremelycontaminated water or food . There are reports of up to a pair of mg/kg of arsenic accumulated in grains and up to ninety two mg/kg of arsenic in straws
Applied by Instrument called Chloronome. Use of Bleaching powder and Hypochlorite (a) Commercially available Calcium hypochlorite (HTH) or perchloron (contains 60% to 70% of Cl2 1 kg HTH for 1 million litre of water is required. (b) Bleaching powder (CaOCl2) Contains 30% of Cl2 They raise pH & hence not used these days Use of Chlorine tablet Single tablet of 0.5g is sufficient for 20 litres of water. Use of Chlorine Dioxide Unaffected by pH. (6 to 10) hence advantageous for treating alkaline water with pH 8 to 10 Types of Chlorination Plain Chlorination Only chlorine treatment to raw water ≈ 0.5 mg/L Pre Chlorination Apply Chlorination before filtration.
Death can be caused with only 3.5g of camphor.3 Santos and Cabot17 described that, camphor is a famous toxin which is responsible for thousands poison cases every year. Nevertheless, it can also contribute to a persist physiologic derangement that leads to some symptoms including nausea, delirium and headache.17To respond research result, the United States Food and Drug Administration set limitations for consumer products to 11% in 1983.3 This suggest that it is important to be careful when using materials that contains camphor. Conclusion In conclusion, it proved by this essay that camphor is a molecule that really changed world. Camphor is widely used in many fields like its medicinal use and insecticide use that have a strongly effect on people’s life. Nevertheless, its discovery and development of synthesis is remarkable in history.
The reason for this is that equines are particularly sensitive to atropine and related tropane alkaloids. Being hindgut fermenters, the alkaloids are absorbed as the contaminated feed passes through the stomach. The mechanism of action of Datura plant after ingestion is that muscarinic receptor antagonists compete with acetylcholine (ACh) for a common binding site on the muscarinic receptors and thus block the action of ACh at muscarinic neuro effector sites on smooth and cardiac muscle, gland cells, in peripheral ganglia and in the central nervous system (CNS). In general they cause little blockade at nicotinic receptor sites (Brown and Taylor, 2001). Datura intoxication produce hyperthermia, tachycardia, painful photophobia and the presence of pronounced amnesia have been reported (Freye and Enno, 2009).
Successful treatment of acute high lethal dose of Acrylamide poisoning Acrylamide has cellular oxidative effects and is classified as 2A carcinogens in human being. Acute or chronic poisonings with this agent happens due to skin, respiratory or oral contacts. Clinical manifestations depend on dose, contact duration and frequency. Management of these patients consists of conservative and palliative therapies for reducing of oxidative effects. Minimal lethal dose of acrylamide is less than 500 mg/kg in adults.
Ethancridine lactate added to the serum or plasma to give a last convergance of 5.2gm every liter. Pretty nearly 90% of the included sum was disposed of with the encouraged proteins, while the rest of which guarantees the complete precipitation of undesirable protein, uprooted by assimilation on charcoal. To sum things up, 1.2% ethancridine lactate arrangement was added to the serum or plasma and the mixture was mixed for 30-40 minutes at 200c and after that the mixture was kept undisturbed for 1-2 hours. After precisely tapping the supernatant the hasten was centrifuged at 5600 g for 30 minutes and the supernatant was pooled. To the supernatant charcoal at the rate of 6g/liter was added to ingest the broke up ethancridine lactate.
It is the most common rice tablet used in Iran to protect stored grains and rice from rodents and pests. A two year epidemiological survey of aluminum phosphide poisoning in Tehran showed that of 340 cases, (68.2%) which were referred in the second year, one hundred (29.4%) of the patients died, most of them were females (59%). There was no significant correlation between sex, age and outcome (8). To determine the causes and mortality of poisoning due to pesticides, a survey was carried out in Loghman-Hakim Hospital Poison Center in
Hence it is required to study in detail the following aspects: • The groundwater reservoir condition • The mode of recharge-discharge relationship • Groundwater movement characteristics with time and space • Determination of the dissolved oxygen in a very effective and scientific way • Oxidation-reduction processes analysed in a more detailed observation Effects: There are various effects found in consuming the arsenic contaminated water. Arsenic is regarded as the slow poison. Slowly it affects the lives who consume it for a long period of time. In West Bengal, Malda, Murshidabad, both 24 Paraganas, Hooghly, Howrah are largely affected by this arsenic contamination. • Various types of skin manifestations • Many arsenic toxicities includes kertosis, malenesia, hyper kertosis, dorsal kertosis, non-pitting edema, lung cancer, liver cancer, kidney failure etc.
