Assessment of the Pesticide Residue Occurrence in Fruit from the South-Eastern Region of Poland During 2010-2011 Seasons

This paper presents surveys on residue levels of fungicides and insecticides applied according to the raspberry protection program. The field trials were conducted in 2013–2014 on a plantation of raspberry of the Laszka variety dessert raspberry very popular in Poland. Laboratory samples were collected starting from a day of the first fruit picking to the end of harvest. The highest mean residue levels were found for boscalid and pyraclostrobin (2.395 mg/kg and 0.732 mg/kg, respectively), in both cases they were at a level of about 24% of their maximum residue levels (MRLs); and for cypermethrin (0.235 mg/kg; i.e. close to 50% of its MRL). The long-term dietary intakes of those substances by Polish adult consumers were also at low levels of 0.52, 0.22, and 0.04% of acceptable daily intake (ADI), respectively. Therefore, the results obtained indicated that even on day zero of picking ripe raspberries, the pesticide residues not only were well below their corresponding MRLs, but also their daily intakes did not even approach 1% of the ADI. In 2013, pesticide residues in ripe fruit evolved according to a pattern different than in a subsequent year; while in 2014 they changed at a constant exponential rate.

“…For example, in 2010-12, 42% of the surveyed samples of raspberries contained pesticide residues; moreover, 4% of them exceeded the MRL . The situation was similar in other years (Sadło et al 2007;Słowik-Borowiec et al 2012). As apparent from other sources (Gnusowski et al 2010), residues of some pesticides appeared also in fruit and leaves of raspberries produced using organic methods.…”

“…However, presence of residues of their active ingredients (AIs), required for the crop protection, is harmful to the health of consumers (Nolan et al 1984;Fenske et al 1990; Lee et al 2004;Piechowicz et al 2012;Piechowicz 2013). Regular research proves that raspberries may contain different and, very frequently, high residue levels of fungicides and insecticides (Sadło et al 2007;Słowik-Borowiec et al 2012;Szpyrka et al 2015).…”

Dynamics of difenoconazole and propiconazole residues on pomegranate over 2 years under field conditions

Residue dynamics of difenoconazole and propiconazole on pomegranate was studied after application at the recommended and double doses of 125 and 250 g active ingredient (a.i.) ha(-1) during August-October 2012. The study was repeated during the same period in 2013. QuEChERS method, in conjunction with gas chromatography (GC), was used for analysis of the fungicides after carrying out the method validation. The recoveries of the fungicides from pomegranate and soil were between 80.3 and 96.2 %; the limit of detection (LOD) and limit of quantification (LOQ) were 0.016 and 0.05 mg kg(-1), respectively. The uncertainties of measurement were between 9.7 and 16.3 %. The initial residue deposits of difenoconazole were 0.875 and 1.205 mg kg(-1) from treatment at the recommended dose and 1.54 and 1.672 mg kg(-1) from treatment at the double dose from the first- and second-year studies. Propiconazole residues were 0.663 and 0.864 mg kg(-1) from recommended dose treatments and 1.474 and 2.045 mg kg(-1) from double dose treatments from the first- and second-year studies. The half-lives of degradation of difenoconazole were 6.4-8.4 days and propiconazole 7.9-8.5 days over the 2 years. Residues of difenoconazole and propiconazole remained on the pomegranate fruit surface and did not move to the edible part (aril). The pre-harvest intervals (PHIs), the time required for the residues to reduce below their respective EU maximum residue limits (MRLs), were 25.4 and 30.8 days for difenoconazole and 33.3 and 43.8 days for propiconazole from treatments at the recommended and double doses, respectively. Keeping in view consumer safety, the longer PHI from the two studies has been selected.
