Risk Assessment of Malathion

The ppm dosage was observed to decrease the weight and brain cholinesterase American Cyanamid Co. However, the Agency for Toxic Substances and Disease Registry,feels that Malathion can be rapidly degraded to harmless substances in the environment, and controlled use of the same possess very trivial risks to the environment and human health.

The pesticide can also delete genes from a DNA molecule. This is the loss that may occur if the risk occurs. Risks to workers and residents were low, with exposures likely to be a small fraction of the acceptable daily intake. Research by the department of preventive medicine shows that new-born babies exposed to malathion on the second trisemester of pregnancy are commonly observed to have gastrointestinal problems Department of Preventative Medicine, The extent of exposure of workers and residents was not estimated.

Since workers were usually engaged in spraying for a large proportion of the day, this demonstrates the need for respiratory protective equipment. There may be a risk to certain beneficial organisms and aquatic life.

Spraying could possibly be done at night so that the pesticide is given enough time to degrade before people go out for their daily activities. Malathion under certain conditions if not used in a pure form or when disposed off into chlorinated water may breakdown into malaoxon which is several times toxic than Malathion.

They noted that the effects were nasal and eye irritatation. Proper sensitization of the general population on how to reduce chances of exposure should suffice in taking care of the possible minimal exposure that may occur.

The proposal is to use the pesticide Malathion in order to control the problem of mosquitoes that could possibly infect the people with the West Nile Virus. Human exposure and exposure to animals and aquatic life in the environment would be trivial APHIS, Exposure can cause rapid severe poisoning with headache, sweating, nausea and vomiting, loss of coordination and death.

The following is my analysis and evaluation of this pesticide. The exception could be if the victim directly ingested the pesticide.

Based on the information that the City of Genericville is facing an epidemic of West Nile Virus Fever, and that an effective solution in the form of Malathion is available to control the mosquito population without significant risk to the environment including human, plant, bird, animal and aquatic lifeI support a vote for using Malathion in pest control programs.

Reduced out-door activities and closure of houses during the spraying program could reduce exposure greatly. This should greatly reduce respiratory exposure.

Malathion Risk Assessment

Most were involved with workers who were engaged in the manufacturing, formulating or applying malathion ATSDR In the yearthe EPA begun to classify Malathion as a suggestive evidence for carcinogenicity, but sufficient evidence for the same does not exist from long-term studies.

This paper describes a simulated application of the OPs concerned fenthion and malathion with measurements of potential exposure through inhalation, dermal contact and deposition of pesticides on surfaces. Last modified on Thursday, 11 July There are some cases where people have attempted suicide.

Hence, Malathion use for the general public had to be registered, although it did not have a significant risk on human health APHIS, Populations living near areas of heavy malathion are at an increased risk for exposure through dermal contact with contaminated plants, inhaling of the mist from the applied insecticide, or by ingesting water or food borne residues.

It is applied by truck-mounted or aircraft mounted sprayers at a maximum rate of 0. Dermal contact is the main type of exposure. Oral administration of technical grade malathion to rats in the long term is observed to increase cases of neoplastic hepatocellular lesions after an 18 months dosing.

As use of Malathion as an insecticide is in very low doses, there is no significant risk that it can cause cancer.

There is very little chance that an individual could get exposed to 16mg of malathion in a single day. The use of malathion by ground application and aerial spraying is generally the preferred method to eliminate adult mosquitoes associated with the West Nile Virus.

Dose response analysis Malathion has low toxicity, however; its ingestion leads to metabolization of malaoxon which is more toxic. Malathion can be applied by spraying trucks or aircraft-mounted sprayers.

The pesticide can also affect animals such as birds and aquatic animals that feed on insects. Plasma and red blood cell cholinesterase activity as indications of the threshold of incipient toxicity of ethyl-p- nitrophenyl thionobenzenephosphorate EPN and malathion in human beings.Method of risk assessment differs depending on the subject of analysis.

Hazard identification Malathion is an organophosphate insecticide that easily degrades in the environment. Malathion is not only harmful to pesticides and mosquitoes but it can also kill beneficial, harmless insects.

Risk Assessment A risk assessment is something that is produced to help carry out a risk assessment of what might cause harm to the service users and what needs to be carried out in order to avoid the risks from taking place.

It is something by law that is expected for all the workplace to carry out. Malathion Risk Assessment Based on surveillance and monitoring Genercville, the wetlands have become a breeding ground for mosquitoes. The proposal is to use the pesticide Malathion in order to control the problem of mosquitoes that could possibly infect the people with the West Nile Virus.

While there has been no proof that Malathion causes cancer, studies have found increased incidences of some cancers in individuals regularly exposed to Malathion such as farmers and chemical applicators (Department of Health and Human Services, ).
