“…Studies have increasingly focused on the techniques for monitoring and measuring methomyl, such as the inspection measurement method (Fernandes et al 2011, Mirmohseni & Houjaghan 2013, as well as techniques for removal (Micó et al 2010, El-Geundi et al 2012. Further, the toxicological effects and the complex changes in soil and its residues in aquacultural products (Hu et al 2010, Kim et al 2013, and the combined effect of its toxicity with other pesti -cides (Meng et al 2014c, Meng et al 2016 have also been studied. The present study evaluated the degradation dynamics of methomyl using orthogonal experimental analysis of environmental factors.…”

Methomyl is a highly effective broad-spectrum carbamate pesticide that is widely used in the control of pests and diseases in crops. However, few studies have assessed the degradation of methomyl residues in aquaculture environments. In this study, the effects of pH, temperature, illumination, and aerobic/anaerobic conditions in pond water were analyzed to study the degradation pattern of methomyl. The pesticide residues in all treatments were extracted per solid-phase extraction technique and analyzed using liquid chromatography-mass spectrometry. The results showed that the degradation process of methomyl satisfied the first-order kinetics reaction, and the half-life and percent degradation of methomyl ranged from 6.19−49.33 d and 21−97%, respectively. Simultaneous variance analysis indicated that all the tested experimental factors had a significant effect on the results, with pH being the most significant. We conclude that methomyl was used frequently in summer, and that high water temperature and long illumination contribute to the degradation of methomyl. We provide theoretical guidance for the safer use of methomyl in production by further reducing the risk from methomyl residues and further ensuring the safety of products from aquaculture.

Assessment of Handler Exposure to Pesticides from Stretcher-Type Power Sprayers in Orchards

et al. 2020

The production and export volume of fruits from China are among the top three in the world. Pesticides are applied to orchards more than 10 times a year to control pests, and stretcher-type power sprayers are widely used to apply chemical pesticides. However, an assessment of pesticide-handler exposure to pesticides in this scenario has not been reported in China. The test pesticide, 30% SYP-9625 concentrate diluted 3000 times, was sprayed on apple orchards in Beijing China. Experiments were conducted to assess dermal and inhalation exposure using standard whole-body dosimetry and air-sampling methodologies. The dermal deposition was the main route of exposure in this study. The dermal unit exposure (UE) of handlers was 350 mg·kg−1 a.i. of SYP-9625. The hands accounted for 59% of the total exposure and were the most exposed body part. Inhalation UE was 0.720 mg·kg−1 a.i. of SYP-9625 and was negligible compared with dermal exposure. We found that use of protective garments while using stretcher-type powers sprayers reduced dermal pesticide exposure. These results can be used as a reference for the handler’s safety in pesticide management and orchard mechanical management.
