“…This is due to the presence of matrix impurities that co-elute with the analyte of interest, and interfere with the signal of the detector, resulting in signal enhancement or suppression [ 38 ]. The matrix effect has been well documented in pesticide residue analysis using GC-ECD [ 39 , 40 , 41 ]. In case of signal enhancement, recoveries above 100% will be obtained in a spiking experiment.…”

(1) Background: Halogenated pesticides are abundantly used in Cameroon, but there is no information on the health risk of consumers from exposure to their residues in foods. (2) Methods: Residues of 20 halogenated pesticides were determined in 11 agricultural products collected in the 3 largest cities of Cameroon using QuEChERS extraction and gas chromatography with electron capture detector (GC-ECD), and health risk from dietary exposure was assessed. (3) Results: Organochlorines pesticides aldrin, p,p’-dichlorodiphenyl-trichloroethane (DDT) and β-hexachlorocyclohexane (β-HCH) found in 85.0%, 81.9% and 72.5% of samples, respectively, were the most frequently detected. The highest average concentrations of residues were 1.12, 0.74 and 0.39 mg/kg for methoxychlor, alachlor and β-HCH, respectively, found in chilli pepper. Chili pepper (58.9%), cowpea (56.8%), black beans (56.5%) and kidney beans (54.0%) exhibited the highest residue occurrences. Levels above the European Union maximum residue limits (MRLs) were found for all the 20 pesticides, in 40.1% of the positive analyses, and the food samples contained 14 pesticides banned in Cameroon. Chronic, acute, cumulative and carcinogenic risk assessments revealed that lifetime consumption of maize, black beans, kidney beans, groundnuts and chili pepper contaminated with aldrin, dieldrin, endrin, HCB, heptachlor, o,p’-DDT, p,p’-DDD, p,p’-DDT, p,p’-DDE and β-HCH, could pose health risks. (4) Conclusion: These results show that there is an urgent need of pesticide usage regulation, effective application of pesticide bans and management of obsolete pesticide stocks in Cameroon.

“…Pesticides improve and stabilize agriculture by controlling of weeds, fungi, and harmful insects. Nevertheless, it is suggested that farmers use at least pesticides with less toxicity and half-life, such as systematic pesticides [7,8].…”

Pesticides are usually used as an effective tool to control pests in agriculture; however, these chemicals may be a threat to nontarget organisms, especially aquatic organisms, because aquatic environments are the last station of pollutants. The present study evaluated the toxicity of a commercial formulation of neonicotinoid (acetamiprid 20% SP) as a systematic pesticide on the survival, hematology, and histology of the grass carp (Ctenopharyngodon idella). For these purposes, 105 fingerlings of the grass carp with an average body weight of 30 ± 2 g were exposed to 0, 50, 100, 150, and 200 mg·L−1 of acetamiprid for 96 h. According to the data, a clear mortality was observed as the concentration of acetamiprid elevated ( P < 0.01 ). The LC50 96 h of acetamiprid was 121.146 mg·L−1. The hematological parameters in fish changed, following exposure to acetamiprid ( P < 0.05 ). Also, a strong correlation was found between acetamiprid concentrations and stress bioindicators such as glucose, total protein, albumin, and cholesterol ( P < 0.01 ). There was not significant tissue damage in the control group (0 mg·L−1 of acetamiprid); however, acetamiprid led to tissues lesions such as hypertrophy, hyperplasia, uplifting of gill filaments, necrosis of gill epithelial cells, pyknosis and karyorrhexis of liver cells, and hemorrhage and necrosis of liver cell. Finally, acetamiprid-exposed fish exhibited some clinical signs including unbalanced swimming near the water surface, increasing operculum movement, and deaths with open-mouthed. The results of the present study clearly showed the survival-reducing effects of acetamiprid in C. Idella, which may return to tissue damage and stress induced by the pesticide. The results of the present study can be used as a base for future studies and environmental management.

“…Analytical methods for the detection of dicarboximide fungicides have been developed, such as gas chromatography–mass spectrometry (GC-MS), 8–10 gas chromatography systems equipped with electron capture detectors (GC-EDC), 11 and liquid chromatography–mass spectrometry (LC-MS). 12 In comparison, the advantages of the simpler immunoassays are significant, such as speed, cost-effectiveness, simple sample pretreatment, and the capability of high-throughput screening.…”
