我们收集某地区一年内农药中毒报告资料646份农药中毒者中,男性235例,女性411例。生产性中毒28例,非生产性中毒618例。生产性中毒以男性占绝大多数,男女之比为1:1.9。中毒者中年龄最大为74岁,最小为5岁。中毒死亡162人,均为非生产性中毒,死亡率为25.1％。农药中毒患者死亡率以“30岁～”年龄组最高,该人群为农村主要劳动力,施药机会多,同时又处在处理婚姻问题、组建家庭、操劳家务的阶段,往往因家庭纠纷、夫妻不和或经济问题等原因而自寻短见者较多所致。 为了掌握农药中毒时间规律,为农药中毒防治工作提供科学依据,我们应用圆形分布法计算平均角度a和角标准差S,通过三角函数代换原理,估计农
Among the 646 pesticide poisoning cases we collected in one year of pesticide poisoning in our region, 235 were men and 411 were women. 28 cases of productive poisoning, 618 cases of non-productive poisoning. Productive poisoning accounted for the vast majority of men, male to female ratio was 1: 1.9. The highest age of poisoning is 74 years old, the minimum is 5 years old. 162 were poisoned, all of which were non-productive and had a mortality rate of 25.1%. The mortality rate of patients with pesticide poisoning is the highest in the “30-year-old” age group. The population is the major labor force in the rural areas. There are many opportunities for pesticide application. At the same time, they are at the stage of handling marital problems, setting up families and doing housework, often because of family disputes, And or because of economic problems and other reasons, see more shortsighted. In order to grasp the regularity of pesticide poisoning, provide a scientific basis for the prevention and control of pesticide poisoning, we use the circular distribution method to calculate the average angle a and the standard deviation S, through the trigonometric function substitution principle,
