In some cases, respiratory sensitization can produce a
severe asthma attack
. As the allergy develops, the reaction can become worse with each exposure. Eventually, even a short exposure to a low concentration of the pesticide can cause a very severe reaction.
What are the bad effects of using chemical pesticides?
Pesticides can cause short-term adverse health effects, called acute effects, as well as chronic adverse effects that can occur months or years after exposure. Examples of acute health effects include
stinging eyes, rashes, blisters, blindness, nausea, dizziness, diarrhea and death
.
What are effects of pesticides?
Any harmful effects that occur from small doses repeated over a period of time are termed “chronic effects.” Suspected chronic effects from exposure to certain pesticides include birth defects, toxicity to a fetus,
production of benign or malignant tumors, genetic changes, blood disorders, nerve disorders, endocrine

How can chemical pesticides enter the human body?
Pesticides can enter the human body by three common ways:
through the skin (contact), the mouth (ingestion), and the lungs (inhalation)
(Figure 2). The state of the chemical, i.e., solid, liquid, or gas, affects the chances of pesticide penetration into the body [25].

sometimes make them poisonous to humans
. Most serious insecticide poisonings result from the organophosphate and carbamate types of insecticides, particularly when used in suicide attempts and, when accidental, in occupational settings.
How long do pesticides stay in your body?
Pesticide half-lives can be lumped into three groups in order to estimate persistence. These are low (less than 16 day half-life), moderate (16 to 59 days), and high
(over 60 days)
. Pesticides with shorter half-lives tend to build up less because they are much less likely to persist in the environment.
What are the harmful effects of chemical pesticides Class 12?
