Malathion is an insecticide which is not natural. When the malathion is pure it's a colorless liquid. The technical-grade malathion includes greater ninety percent malathion and impurities in a solvent which is a brownish-yellow liquid. Malathion is used to kill insects found on crops and in gardens. Malathion is used to kill mosquitoes and Mediterranean fruit flies in vast areas of land. It is also used to treat lice on humans and fleas on animals.
Hazard identification is being able to recognize the potential of a substance that may cause harm to human health or the environment. There is not any decisive evidence that malathion can cause cancer within humans. Humans such as farmers and pesticide applicators who are regularly exposed to pesticides have a risk of some cancers. Birth defects have not been found in human exposure to malathion. Although, developmental effects were observed in the offspring of animals ...view middle of the document...
Some difficulties that may occur for a human are trouble breathing, a taut chest, cramps, vomiting, and diarrhea. Also, more severe difficulties that may occur for a human are sweating, blurred vision, headaches, lightheaded, losing consciousness, and death. There is a chance of not having any deleterious long-term effects as long as the human who has been exposed to high amounts of malathion is expeditiously given the correct treatment. When humans have had exposure to levels of malathion below those that affect the brain and nerve function there seems to be a few or no health issues at all.
Most humans do not have any exposure to malathion in the air they breathe and whatever they may touch. Although, the humans that are located near the area that's being sprayed will probably be exposed to malathion if they do not take any precautions. The people that have a high chance of being exposed to malathion are farmers, chemical sprayers, and factory workers who create malathion. Humans who live close to landfills where malathion has been dumped are at a risk of being exposed. Then people who use malathion within their homes obviously are at risk of exposure as much as people that go into fields too soon after malathion had been sprayed. Malathion makes its entrance to the environment by being sprayed on to farm crops. When malathion reaches the soil it does not stick and deteriorates quickly by bacteria in soil which does not enter into groundwater. Malathion in water is diminished by the movement and bacteria. The sun light breaks down the malathion in the air.
The risk characterization assessment includes imaging of contaminants, exposure and toxicity to quantify. Then also it assumes the risks of the population, communities and ecosystems from contaminants. The proposed pesticide application program may reduce the population of the mosquitoes and risk of the West Niles Virus by ninety percent. If the program is allowed, the projected number of West Niles Virus cases would decrease from fifty to five which will leave a chance lower than twenty percent for a fatality in each of the five cases.
