基于PCA和TOPSIS的植保无人机施药过程中施用人员的暴露量评估
Assessment of Applicators'Exposure during Pesticide Application with Plant Protection Drones based on PCA and TOPSIS
摘要
Abstract
[Objective]Pesticide applicators are still inevitably exposed to pesticides although agricultural drones have greatly reduced the exposure during the application.To provide rational recommendations to improve their applying methods and habits,so as to achieve the goal of reducing their physical exposure to pesticide and thereby lowering the risk of exposure,we carried out a comprehensive evaluation about the exposure levels of each part of the protective clothing worn by applicators during pesticide application by the plant protection drones.[Methods]The nested design was adopted in this study,with crops corn and rice as the first level factors,the applicators drone pilots and ground crew as the second level factors,and the parts of the protective clothing as the third level factors,and 11 parts of the protective clothing as 11 research levels.In the research,the coefficient of variation was used to determine the body parts where exposure in most easily controlled,the correlation coefficient was used to determine the correlation between the exposure levels and body parts;the principal component analysis and TOPSIS was used to conduct comprehensive evaluation of applicators,and hierarchical clustering method for clustering.[Results]The coefficient of variation is the greatest in the back and lower legs,making them the body parts where exposure is easiest to control.The average exposure in the forearm and upper arm is the greatest,while the coefficient of variation is relatively low,indicating the exposure is more difficult to control;there is an extremely significant correlation in the unit exposure level among the upper arm,forearm,back and lower leg of applicators.When principal component analysis and TOPSIS method were respectively applied to comprehensively evaluate the unit exposure of each part of the body of applicators,the unit exposure of 12 applicators ranks completely the same.It has a statistical significance when the hierarchical clustering method was applied for clustering and the results were divided into three categories.[Conclusion]In this case,applicators with high-risks need to pay attention to a whole-body protection,those with medium-risks should pay attention to the protection for the head,neck,forearms,chest,thighs and hands,while those with low-risks only need to keep their current application habits.关键词
