“…However, pesticide exposure was related to a variety of human health effects. [1][2][3] Nowadays, great attention has been focused on chiral pollutants, the biological transformation and environmental fate of which can be stereoselective. 4,5 The enantiomers of the chiral pesticides show different activities in biological systems because of their differential interaction with enzymes or other naturally occurring chiral molecules.…”

Influence of lactic acid bacteria on stereoselective degradation of theta‐cypermethrin

et al. 2017

The purpose of this study was to investigate the influence of four kinds of Lactic acid bacteria (LAB) on stereoselective degradation of theta-cypermethrin (CYP), including Lactobacillus plantarum, Lactobacillus casei, Lactobacillus delbrueckii, and Streptococcus thermophilus. An effective analytical method for (±)-theta-CYP in medium was developed by high-performance liquid chromatography with cellulose tris-(3,5-dimethylphenylcarbamate) chiral stationary phase. theta-Cypermethrin was spiked to LAB medium with different inoculation rates and sampled at 0, 2, 8, 24, 36, 48, 72, 120, 168, and 240 hours. The results showed that LAB influenced the half-lives and enantiomer fractions of theta-CYP enantiomers, which lead a closer degradation rate between the 2 stereoisomers, and no obvious difference was found among 4 LABs. Besides, the stereoselective degradation of theta-CYP was closely related to pH. The lower the pH (pH of 3, 5, 7, and 9), the lower the enantiomer fraction (from 4.88 to 6.69). At pH of 3, 7, and 9, significant differences of half-lives between enantiomers were observed. (-)-theta-Cypermethrin decreased faster than (+)-theta-CYP under pH of 3, while opposite results were indicated under pH of 7 and 9. Moreover, the acidic condition contributed to the higher chiral configuration stability of (±)-theta-CYP. (+)-Enantiomer was influenced by pH in a greater degree than (-)-enantiomer.

“…Apparently, the traders are not sufficiently informed on the risks associated with inhalation of grain dusts and organic and inorganic chemical agents in pesticides/rodenticides often used in foodstuff warehouses. Some of these pesticides have been detected in grains/vegetables [2, 3] and are oftentimes misused due to nonadherence to caution, which might be common among illiterates. In fact, there is a correlation between high levels of occupational exposure to pesticides and low educational levels [4], probably due to their inability to read and adhere to hazard warnings found on each pack.…”

Background. Foodstuff traders operating from warehouses (FTFW) are potentially exposed to dangerous rodenticides/pesticides that may have adverse effects on cardiopulmonary function. Methods. Fifty consenting male foodstuff traders, comprising 15 traders (21–63 years) operating outside warehouses and 35 FTFW (20–64 years), were randomly recruited at Ogbete Market, Enugu, in a cross-sectional observational study of spirometric and electrocardiographic parameters. Seventeen FTFW (21–57 years) participated in focus group discussions. Qualitative and quantitative data were analysed thematically and with independent t-test and Pearson correlation coefficient at p < 0.05, respectively. Results. Most FTFW experienced respiratory symptoms, especially dry cough (97.1%) and wheezing (31.4%) with significant reductions in forced vital capacity (FVC) (t = −2.654; p = 0.011), forced expiratory volume in one second (FEV1) (t = −2.240; p = 0.030), maximum expiratory flow rate (FEF200–1200) (t = −1.148; p = −0.047), and forced end-expiratory flow (FEF75–85) (t = −1.11; p = 0.007). The maximum mid-expiratory flow (FEF25–75) was marginally decreased (p > 0.05) with a significantly prolonged (p < 0.05) QTc interval. Conclusion. Allergic response was evident in the FTFW. Significant decrease in FVC may negatively impact lung flow rates and explains the marginal decrease in FEF25–75, which implies a relative limitation in airflow of peripheral/distal airways and elastic recoil of the lungs. This is consistent with obstructive pulmonary disease; a significant decrease in FEF75–85/FEV1 supports this conclusion. Significant decrease in FEF200–1200 indicates abnormalities in the large airways/larynx just as significantly prolonged ventricular repolarization suggests cardiac arrhythmias.

“…During agricultural production, spraying of chemical pesticides to control and prevent the negative effects of pests and insects is a necessary measure to increase crop yields, which equates to preventing approximately 30% of economic losses. Nonetheless, these pesticides are often toxic and leave residues that are difficult to degrade, especially when they are used excessively or in an unregulated manner (Lozowicka et al, 2014). Currently, various levels of pesticide residues are found in agricultural produce worldwide (Dalvie & London, 2009;Jardim & Caldas, 2012;Łozowicka et al, 2012;Wang et al, 2013;Szpyrka et al, 2015), which creates a bottleneck in the international trade of food commodities.…”

Summary In agriculture, pesticide residues have always posed a major safety hazard to human health. With the development of agricultural production and improvements in science and technology, additional methods for degradation of pesticide residues have emerged. Amongst them, ozone treatment recently became a popular method owing to its outstanding technical advantages. This review is an in‐depth analysis of the mechanisms by which ozone treatment degrades pesticide residues. The main mechanism involves direct oxidation by oxygen atoms, and indirect oxidation driven by hydroxyl radicals. The effects of ozone treatment on pesticide residues in food with respect to the ozone concentration, duration of ozone treatment, type of food, variety of pesticides, level of pesticide residues and environmental factors have been discussed. Furthermore, the impact of ozone treatment on the quality of food is highlighted. Low levels of ozone result in minor changes to the visual and sensory characteristics of food. In addition, this article discusses several restrictions surrounding the current application of ozone treatment for the degradation of pesticide residues. More specifically, the most crucial issue is the potential toxicity of ozonation byproducts generated by the process, which is also the current focus of research on ozone treatment for the degradation of pesticide residues. After weighing the advantages and disadvantages of ozone treatment, it is recommended as a method of degrading pesticide residues.
