- Pesticides are the chemical substances that are designed to kill pests. Many pesticides can put adverse affect on human health. To determine risk, one must consider both the toxicity and hazard of the pesticide and the likelihood of exposure. A low level of exposure to a very toxic pesticide may be no more dangerous than a high level of exposure to a relatively low toxicity pesticide, for example.
- Pesticides can lead to short-term health effects that are known as acute effects, as well as chronic adverse effects that can take months or years to show effect after exposure. Some acute health effects are rashes , blisters on the body ,stinging eyes, blindness, nausea, dizziness, diarrhea and death. Examples of known chronic effects are cancers, birth defects, reproductive harm, immune toxicity, neurological and developmental toxicity, and disruption of the endocrine system.
- Some people are more prone to impacts of pesticides than others. Effects of pesticides can be seen in every age group. But infants and young children are more susceptible to the toxic effects of pesticides than adults . Occupation can also make a difference as Farmers and pesticide applicators are more vulnerable to the affects because they more exposure to pesticides.
Acute (Immediate) Health Effect
Acute health effects are seen in people after immediate exposure from pesticide symptoms may include
- Irritation of the nose, throat, and skin
- Burning sensation in skin
- Itching, rashes and blisters.
- Nausea, dizziness and diarrhea
- Sometimes difficulty in breathing
- Severe reactions are seen in people who are suffering with asthma. Some pesticides cause more severe reactions mainly pyrethrin/pyrethroid, organophosphate and carbamate pesticides.
- As symptoms of pesticide poisoning mimic symptoms of other conditions like cold or the flu. Due to this reason, pesticide poisonings are often misdiagnosed and under-reported. Immediate symptoms of poisoning are not severe enough that an individual have to take medical attention, or a doctor might not even think to ask about pesticide exposure. Still immediate consultation of doctor is required if you have any doubt that you may have been poisoned by pesticides.
Chronic (Long-term) Health Effects
Chronic health effects of pesticide poisoning occur after long term exposure of pesticides. These include
- Cancer and other tumors
- Brain and nervous system damage
- Birth defects
- Infertility and other reproductive problems
- Can cause damage to the internal organs like lungs, liver, kidneys and other body organs.
Cancer
Many studies shows that effects of pesticide exposure has increased the risk of cancer. Body parts that are involved include kidney, pancrease , liver , lung and skin. Increased risk of cancer have been found in the farmers who apply these chemicals in the farms Exposure to insecticides within the home and herbicides outside is associated with blood cancers in children.
Neurological
Researchs have shown that pesticide exposure to people have worsened neurological disorders outcome.
Reproductive effects
Pesticide exposure To Pregnant ladies can lead to birth defects, fetal death and also put adverse effect on fetal growth. It has also been associated with bad health and genetic effects. It was also noted that new born when at some point exposed to pesticides had a low birth weight and developmental defects.
Fertility
A number of pesticides affect fertility in males. Pesticide exposure in males reduced fertility in males, genetic alterations in sperm, a reduced number of sperm, damage to germinal epithelium and altered hormone function.
Others
Some studies have found that pesticide exposure can also lead to many kind of skin conditions like dermatitis.
Poisoning can leads to respiratory problems.
People who are exposed to pesticides are at greater risk of diabetes.
Children are More Vulnerable to Pesticide Exposure
- Children are more susceptible to infection because their organs, nervous systems and immune systems are still developing. Metabolism system is also not that much developed in so children are not able to detoxify properly and excrete the harmful toxins and pesticides . Exposure during growing period can also increase the severity of symptoms in children.
- Moreover children have a higher respiratory rate and more exposure to airborne pesticides is there at a faster rate than adults. Children also consume proportionately more food and water — and pesticide residues — than adults. Children have more contact with grounds and playgrounds so their chances of exposure to pesticides poisoning increases.
Health Effects of Certain Classes of Pesticides
- Organophosphates & Carbamate- These pesticides affect the nervous system and brain. So in this poisoning impairment of signal transmission occur. Symptoms of this poisoning include nausea, headaches, nausea, vomiting, pain in chest pain, muscle pain and confusion. In severe poisoning cases convulsions, difficulty breathing, involuntary urination, coma and death may occur.
- Soil Fumigants:These pesticideswhen applied to soil, forming a gas that is toxic to nematodes, fungi, bacteria, insects and plants in the soil. Because of the gases, they move from the soil into the air and affect people living or working nearby. These commonly affect the respiratory system in the people and leads to symptoms like headache, sunken eyes, infections in lungs etc.
- Pyrethroids: These are the chemicals compounds that are similar to botanical compounds but have been designed to be more persistent. They are also toxic to the nervous system. Symptoms of pyrethroid poisoning include salivation, tremors, headache, fatigue ,itchy skin and involuntary twitching etc.
Route of Exposure
- People can be exposed to pesticide poisoning by a number of different routes of exposure include: occupation, air-borne and in their food.
- There are concerns that pesticides used to control pests on food crops are dangerous to people who consume those foods. These concerns are one reason for the organic food movement. Many food crops, including fruits and vegetables, contain pesticide residues after being washed or peeled.
The Final word
- Exposure to pesticides can affect the health of people and can lead to severe health risks. So proper preventions must be taken while doing work in farms . Also people should be use vegetables, fruits after proper washing or cleaning. Extra care should be given towards children.
