“…The impact of pesticide residues can be minimised by preventive measures such as rational use of pesticides, washing and proper processing of food products, practicing organic farming, use of natural pesticides and bio-pesticides, and strict implementation and amendment of pesticide-related laws (Grewal et al 2017).…”

Abstract A study to investigate commonly grown vegetables, commonly used pesticides, and pesticide use practices was conducted in Kabale District, in south-western Uganda. This is because indiscriminate pesticide use and poor application practices can leave pesticide residues in food rendering it unsafe for consumption. The study revealed extensive pesticide application in Brassica oleracea; var. capitata (cabbage), Brassica oleracea; var. botrytis (cauliflower), Solanum lycopersicum, (tomato) and Beta vulgaris (beet root). Information obtained using interviews revealed that 16.5% traders sell pesticides and 70% farmers spray pesticides on vegetables. Only 18% of farmers could interpret instructions correctly on a given pesticide container label. All farmers (100%) had never attended any pesticide use training. Cypermethrin, dimethoate, dichlorvos, metalaxyl, profenofos, malathion and mancozeb were common pesticides used in spraying vegetables however 42% of the farmers mixed different pesticides for use. Limited knowledge about pesticide application, inability to interpret instructions, non-observation of waiting period before harvesting, mixing pesticides and lack of training on pesticide use for farmers are potential risks to food safety. There is need to address knowledge gaps on safer pesticide application in order to attain safe agricultural productivity for sustainable food security, human health and community development in Kabale District, Uganda.

“…According to Romanian national legislation (which includes the official monitoring program), many plants/ vegetables and their derived products are subjected to pesticide and heavy metals analysis, the maximum residues limits (MRL) being regulated by European Regulation (EU) 396/2005, Commission Regulation No 1881/2016, Codex Stan 193 FAO/1995, and GB 2762/2017 [7,10,14,27,32]. In some cases, from unknown reasons (failure to comply with good agriculture practice or others), the crops might be involuntary contaminated with pesticide residues and heavy metals [13,16,17,20,34,36,44]. Of great importance is that a large amount of plant products (which are part of food supplements) are not checked/ monitored, regarding possible residues and this can lead to serious risks for human health [3,4,6,15,25,41,42].…”

Taking into consideration, that peppermint tea is frequently used in phytotherapy due to its wide range of therapeutic effects, ten samples of peppermint leaves were analysed in order to assess the level of pesticide residues and heavy metals. Pesticide residues were under the detection limit for six samples. However, in four peppermint samples we have determined λcyhalothrin (42-45 µg/kg), chlorpyrifos-ethyl (20-43 µg/kg), and cyfluthrin (78 ± 21 µg/kg), in concentrations below the maximum residues limits. In order to evaluate the negative impact of pesticides on patients health, a sample was spiked with the most common pesticide residues used in agricultural practice, by accumulation in the herbal product (diphenylamine 195.8 ± 16 µg/kg, chlorpropham 108.6 ± 12.4 µg/kg, hexachlorobenzene 76.7 ± 6 µg/kg, tolclofos-methyl 111.4 ± 39 µg/kg, cyfluthrin 472.7 ± 39.7 µg/kg). Moreover, we have observed that pesticide residues had a high transfer rate in infusion (diphenylamine 71.5%, chlorpropham 158.4%, chlordane-gamma 63%, tolclofos-methyl 61.5%). From the point of view of the heavy metals content, the sample shown concentrations over allowed limits (cadmium 98 µg/kg, copper 7140 µg/kg, lead 1500 µg/kg, mercury 170 µg/kg), some being transferable in infusion (nickel 123.3 %, copper 28%). Rezumat În acest studiu au fost analizate zece probe de frunze de mentă în scopul evaluării nivelului de reziduuri de pesticide şi metale grele. Reziduurile de pesticide au fost sub limita de detecţie pentru şase probe, iar în patru probe de mentă au fost determinate λ-cihalotrin (42-45 µg/kg), clorpirifos-etil (20-43 µg/kg), şi ciflutrin (78 ± 21 µg/kg), în concentrații sub limitele maximale. Pentru a evalua impactul negativ al pesticidelor asupra sănătății pacienților, o probă a fost fortificată cu cele m ai frecvent folosite pesticide în practica agricolă, constatându-se o acumulare în produsul vegetal (difenilamină 195,8 ± 16 µg/kg, clorprofam 108,6 ± 12,4 µg/kg, hexaclorbenzen 76,7 ± 6 µg/kg, tolclofos-metil 111,4 ± 39 µg/kg, ciflutrin 472,7 ± 39,7 µg/kg). Am constatat faptul că reziduurile de pesticide prezintă o rată de transfer crescută în infuzie (difenilamină 71,5%, clorprofam 158,4%, clordane-gamma 63%, tolclofos-metil 61,5%). Din punct de vedere al conținutului de metale grele, proba prezintă concentrații peste limitele permise (cadmiu 98 µg/kg, cupru 7140 µg/kg, plumb 1500 µg/kg, mercur 170 µg/kg), unele fiind transferabile în infuzie (nichel 123,3%, cupru 28%).

“…Pesticide residues, caused by conventional usage routes like customarily spraying or mixing them with soil, undoubtedly have received considerable attention in recent years because of their high toxicity to the ecosystem and human health [1,2]. To solve this problem, some remedial measures, including natural degradation [3], biotreatment [4], ion exchange [5], and electrochemical and physical methods [6], have been proposed.…”

To alleviate the adverse effects of pesticide residues on the environment, development of a more safe, economical, and reliable usage approach of pesticides is critically urgent. In the present study, a novel pesticide carrier LA-NSM (lauric acid-modified Nitraria seed meal) with controlled release property was prepared through grafting esterification of lauric acid onto Nitraria seed meal substrates. The structure of the obtained samples was characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, and contact angle measurements. The results indicated that LA-NSM products had a well-defined hydrophobic surface and irregular holes for efficient loading of pesticide molecules. Deltamethrin (DEL), a representative insoluble pyrethroid insecticide in water, was deliberately selected as the index pesticide to evaluate the loading and releasing efficiency of LA-NSM. The loading capacity of LA-NSM for DEL can reach about 1068 mg/g. pH, humidity of soil, and temperature had a significant influence on controlled release performance of LA-NSM@DEL. Moreover, the releasing kinetics of LA-NSM@DEL composites could be fitted well with the Higuchi model. Overall, the highly hydrophobic property, excellent loading, and controlled release ability of LA-NSM made it a promising candidate in agricultural applications.
