Factors Affecting Poison and Blood Chemical Levels of Farmers in KhamSakaesaeng District, NakhonRatchasima.

Abstract

This study has objectives to evaluate the rate of system toxicity from the chemical residues
in the blood of farmers locating in Khamsaengsaeng District, NakhonRatchasima Province, and determine
the factors affecting the toxicity of the blood chemicals of farmers. A Questionnaire was used as an
instrument for collecting data from 400 farmers between October to December 2016 Statistics used
for data analyses were descriptive statistics presenting with frequency, percentage, mean, standard
deviation, and multivariable logistic regression. The results of chemical residues in farmer’s blood

found that most chemical substances caused the most toxic symptoms were the musculoskeletal
system 30.60%, followed by the nervous system 22.00% and the respiratory system 19.4%.
In the musculoskeletal system and tender, most symptom found was fatigue 30.9%. Nervous system
found was headache 45.9% and respiratory tract system was irritation and neck spasms 38.2%.
With the toxicity of chemicals in the farmer’s blood, the results from multivariable logistic regression
showed statistically signi cant at p-value <0.05 of spray duration (ORadj = 1.91, 95% CI = 1.15-2.41,
p-value <0.001), some weed species (ORadj = 4.15, 95% CI = 1.47-11.70, p-value = 0.006),
and chemical use behavior (ORadj = 0.45, 95% CI = 0.32-0.65, p-value <0.001). In conclusion,
toxicity in farmer’s blood chemicals still a major problem. All sectors must seriously collaborate
and work together to reduce chemical residues in both agricultural related work and in vegetables which
may alleviate public health in general population.
