피나물 중 Bocalid 및 Pyraclostrobin의 토양처리시 잔류특성 및 안전성 평가 = Residue Characteristics and Risk Assessment of Pesticides (Boscalid and Pyraclostrobin) in Hylomecon Vernalis

다국어 초록 (Multilingual Abstract)

Hylomecon vernalis is widely distributed in mountainous region in korea and used as folk madicine. Due to minor cultivation area, the pesticides available for Hylomecon vernalis are highly limited. This study aimed to determine residue characteristics of soil-treated boscalid and pyraclostrobin in Hylomecon vernalis and to evaluate the risks from intake of the residual pesticides in the crop.
The pesticides were treated in soil with two levels, and samples were collected 57 days after seeding. The samples were extracted using the QuEChERS extraction kit (MgSO4 4 g, NaCl 1 g). The quantitative methods for boscalid and pyraclostrobin were validated using linearity, recovery, and CV (coefficient of variation). Risk assessment of pesticides was performed using Korea national nutrition statistics 2019.
The residual levels of boscalid were 0.02∼0.05 mg/ kg (6 Kg/ 10a) and 0.05∼0.08 mg/kg (12 Kg/ 10a), respectively. The residual concentrations of pyraclostrobin were below the LOQ. The amounts of pesticides were less than Maximum Residue Limits specified by the Korean Ministry of Food and Drug Safety. The maximum hazard index of boscalid in chwinamul and amaranth for consumers were 0.0075% and 0.1525%, respectively and it indicates that the risk of the pesticides from the crop is considered to be low.
