| Tóm tắt: | This study uses the Environmental Impact Quotient (EIQ)to assess the health and ecological risks caused by fungicides used in chrysanthemum cultivation upstreamof Xuan Huong Lake, DaLatcity. Survey results reveal that 134 farmers use 21 fungicides with 18 active ingredientson a total area of 35.2 hectares. In all,18 fungicides with an EIQ at the level of “unlikely to be hazardous”(EIQ < 25)are used on about 95% of the acreage,and 3 fungicides with an EIQ of “slightly hazardous”(25 < EIQ < 50)are usedon the rest of the area. The Field Use EIQ of fungicide was ratedvery low in only 8.2%of the survey area andmoderate in 48%. Areas with high and very high ratings account for 3% and 41%, respectively. Using fungicides according to the instructions can reduce the Field Use EIQ values in cultivated areas by 38% and return areas with highand moderate ratings to a low rating. Therefore, it is necessary to instructfarmers on thesafe use of fungicides and to recommend thosewith low EIQ values for chrysanthemum cultivation |
