Pest is any living organism that interferes the production, processing, storage, transport or marketing of food, agricultural commodities, wood and wood products or animal feedstuffs. It can also be used as plant growth regulator, defoliant, agent for thinning fruit or preventing the premature fall of fruit and used as substances that are applied to crops either before or after harvest to protect the commodity from deterioration during storage and transport. 
These 4 are the EPA(envprotection agency) approved pesticides
The Poison Information Centre in NIOH has reported the OP compound were responsible for the maximum number of poisoning amongst all the other agricultural pesticide.
Pesticides can be found everywhere in our environments such as homes, workplaces,
Another concept in toxicology that applies to the understanding of human health effects is associated to the exposure is potency. Not all pesticides are equally potent or have the capacity to create the same level of health threat.  Pesticide toxicity in human is also affected by other factors such as age, gender and health status of the individual as well as the intensity and frequency of pesticide used. In comparison to adults, children tend to have greater risk of poisoning.
Chronic exposure to these chemicals may cause symptoms of mild cognitive dysfunction and hormonal imbalances. Ultimately, these toxins are stored in the fatty body tissues and in brain cells. It is recirculated in blood before being released. This may lead to many chronic illnesses.
Skin: If pesticides are spilled on the skin, immediately wash with soap and water.Clothes: Contaminated clothes are removed and washed separately. Eyes: If contact with eyes, wash with copious amounts of water.Symptoms of poisoning are monitored by specific treatment (antidote) of pesticide poisoning.The basic mgt include airway protection, skin decontamination, gastrointestinal decontamination, and convulsion treatment.
When studying pesticides it is important to recognize two key characteristics. Firstly, most of them are persistent, which means they do not break down into safer constituent parts but rather remain intact over long time. Secondly, they are readily accessible to the human body. Persistent organochloride pesticides are the most prominent example as these chemicals are not readily broken down in the environment and it tends to accumulate in human body. The effects of pesticides on human health are greatly determined by the amount of pesticide accumulated, the potential toxicity, the duration and frequency of exposure of the pesticide. Studies also demonstrated specific chronic pesticide effects may appear in older people due to long latency period between exposure and disease.

“ Pesticide is any substance or its mixture thatis used for preventing, destroying or controlling any pest, which includes vectors of human or animal disease as well as unwanted species of plants or animals that causes harm. ”
A pesticide must be lethal to the targeted pests, but not toman.On the basis of pest control, ( against insectpest), (killing and controlling weeds) while (prevent, destroy, repel or mitigate rodents).In terms of chemical composition: Anthranilic diamide, carbamate, pyrethroids, organochloride, organophospate and neonicotinoid Anilide 4-Hydroxycoumarins
Did you know that only 5% ofpesticides sprayed actually reachtheir target? And the rest of it go to:- The food we eat The water we drink The air we breath So, how do they act on our body??
CLASS IA is extremely hazardous and demarcated in red CLASS IB is highly hazardous and symbolized by an yellow trianglePesticide Acute toxicity --- Classification CLASS II is moderately hazardous of WHO and marked by a blue triangle CLASS III is slightly hazardous CLASS IV is unlikely to cause acute hazard in normal use

1. DEATH-- Pesticides have been associated with a number of illnesses. 2. RISK-- Fleming et al (2003) discovered thatfarmers were at greater risk of accidental mortality. 3. CANCER-- Both male and female workers hadhigher risk of cancers of the nervous, lymphatic and hematopoietic systems.
