| 中文摘要: |
| 为探究除草剂在实验室和农业实际使用过程中挥发性有机化合物(VOCs)的排放规律,本研究分别测算了除草剂施用引起的VOCs排放潜力(EP)和实际排放量(AE),深入探究了除草剂VOCs的实际排放及其气象环境响应关系,确定了实际排放比(AER)。结果表明:7个典型农药品种的EP为6.57%~64.37%,中位数为14.10%,全部受试品种平均值为27.80%;不同农药制剂品种的平均AER在47.366%~71.584%之间。AER值与温度呈显著正相关,与相对湿度和大气压强呈显著负相关。研究表明,除草剂施用过程中VOCs的排放潜力与实际排放量存在剂型差异,且表现出明显的气象环境响应机制。 |

| As there appears to be a notable lack of research on the volatile organic compounds(VOCs)pollution of herbicides, we aimed to assess the occurrence of herbicide VOCs in the laboratory and during the agricultural process in China that have not been previously investigated. For this purpose, we discuss the estimation of VOCs emission potentials(EP)and actual emissions(AE)posed by herbicide applications in depth exploration of the actual VOCs emissions and meteorological factor response relationship of herbicides in agricultural production applications. The results showed that the EP of seven herbicide samples ranged from 6.57% to 64.37%, with a median of 14.10% and a mean of 27.80%. The average actual emission ratio(AER)for the different formulations ranged from 47.366% to 71.584%. AER value was significantly positively correlated with temperature, but significantly negatively correlated with relative humidity and atmospheric pressure. This study indicated that the formulation differences between the potential and actual emissions of VOCs existed during herbicide application, and the change responded to the driving mechanism of significant meteorological and environmental factors. |
