Pesticides are commonly used in the agricultural activities worldwide, and it is almost impossible to produce the huge amounts of agricultural products without using pesticides in the modern world. Besides the benefits of using pesticides, it is important to notice the dangerous of using them. Pesticides are some chemicals which are toxic to the insects in order to prevent damages from them. In addition, some of the pesticides will pollute the environment, and the most important fact is that pesticides are also a toxic chemical for human. There are numerous types of pesticide can be used in the field, and researches stated that people will be affected if they expose to pesticides without proper protections. Moreover, some pesticides had been …show more content…
The consequences were explained by the researchers. The short-term exposures to pesticides was related to symptoms such as headache, skin problems, and nausea, etc. Other than the subjective symptoms, researchers also discovered some physiological changes by conducting blood tests in order to provide more data in an objective point of view. They found out that short-term exposures (three days working in the farm) had significant effects on some health indicators such as hemoglobin, hematocrit, red blood cell, and monocyte percentage, etc. In addition, increased liver enzyme, blood urea nitrogen, and decrease in plasma protein are some examples of the effects obtained from the blood chemistry tests (Hu, Huang, Huang, Li, Zhang, Yin, Chen, Jin, Cai &Cui, 2015). These changes are all abnormal for the healthy body. Therefore, the tests showed that the short-term exposures had adverse effects on the farmers’ bodies. Moreover, it is reasonable to correlate the causes of the symptoms and the changes of health indicators. Furthermore, the symptoms may act as alerts for the body for the abnormal changes of the body. Another group of researchers found the similar results, and demonstrated the health problems of short-term pesticide exposures. Many pesticides were associated with many acute health problems, and one of them called organophosphate. It was associated with …show more content…
According to Hu et al. (2015), long-term pesticides exposures were associated with abnormalities in renal function, hepatic function, and nervous system, etc. Meanwhile, the authors mentioned that two main health issues were related to long-term exposures, and they were nervous system and hematological system. As the sensory nerves dad been damaged, it might cause peripheral neurotoxicity. Besides, as the increased in the level of white blood cell was measured, the authors stated that it might increase the risk of getting hematopoietic cancers. Long-term pesticide exposures are associated with many serious chronic health problems, and they are life-threatening. Therefore, pesticide exposures should be avoided. Another group of authors stated some similar findings regarding to the chronic health issues of long-term pesticide exposures. Researchers found that neurologic deficits, birth defects, miscarriages, cancer, and memory disorders were some health problems related to the pesticide exposures (Arcury et al., 2006). Both articles described the chronic health problems. Thus, they both mentioned cancers and cognitive system were related to the long-term exposures. Furthermore, an article showed that long-term pesticide exposures were related specifically to bladder cancer. The study found that people with experiences of using pesticides (imazethapyr and imazaquin) had
