Residual characteristics of pesticide in banana from international pesticide residue monitoring data

Abstract

This study was designed to use the safety management data for residual pesticides in imported banana based on the investigation of pesticide residue detection of agricultural products with different origins in the Republic of Korea. From the USA, EU, UK, Japan and Korea from 2007 to 2018, the results of banana residue pesticides were summarized into detected pesticides, number of inspections, number of pesticide detection cases, and the amount of detected pesticide residue. A total of 109 pesticides were detected for the pesticide residue and pesticide detection rate was 4.58% in 206,894 cases. The detection rate was ranged within 10.62-24.62% for chlorpyrifos, imazalil, methyl-bromide, azoxystrobin, carbendazim, pretilachlor and thiabendazole. Among them, chlorpyrifos was detected most often followed by imazalil, azoxystrobin, thiabendazole, bifenthrin and carbendazim. According to the results of monitoring data for bananas in EU, Japan, USA, UK and Korea, the kinds of detected pesticides were 85, 57, 23, 18 and 8, respectively. Azoxystrobin, bifenthrin and chloropyrifos were found in monitoring data of all countries. Fourteen and twelve pesticides were detected in bananas from Costa Rica and Ecuador, respectively. Imazalil and thiabendazole were detected in 16 and 11 origins, respectively. Myclobutanil and iprodione were detected in four and two countries, respectively. In bananas from Costa Rica, azoxystrobin and bifenthrin were detected 11.8 and 9.8%, respectively, and the detection rate of azoxystrobin was 19% in bananas from Colombia. Chlorpyrifos was detected 22.7, 13.3 and 10.8% in bananas from Belize, Colombia and Costa Rica respectively. Myclobutanil was detected in bananas from Colombia and Costa Rica with the rate of 17.9 and 10.4%, respectively.

Comparison of the plant uptake factor of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) from the three different concentrations of PFOA and PFOS in soil to spinach and Welsh onion

“…Especially, PFOA, PFOS and those related compounds have been listed on persistent organic pollutants (POPs) in Stockholm Convention [17,18,29,31,32]. Although the POPs had been banned to produce and use in commercial products, there were frequently detected in environment, crops and wildlife as well as in human [2,14,20,[24][25][26]28,30]. To know the current exposure level of PFOA and PFOS in human, many scientists reported the exposure assessment and scenarios from air, water, food and living environment [1,4,13,37,38].…”

Potential of Baeyer-Villiger monooxygenases as an enzyme for polyethylene decomposition

“…이로 인하여 PE의 생분해가 비교적 어려운 것으로 알려져 있 으며, 분해되는 데 걸리는 시간은 HDPE의 경우 약 100년, LDPE의 경우 최소 500년 이상으로 알려져 있다 [9]. 이는 다른 환경 위해요인들과 더불어 토양에 오랫동안 잔류가 가능함을 나 타낸다 [10][11][12].…”
