“…The mean concentration of Cadmium in both fish species is comparable to the WHO/FAO maximum permissible limit of 0.2 mg/kg for food samples. However, the concentration is very much comparable with the recent study with the concentration from 0.17 -0.32 mg/kg (Akoto et al, 2014). Though the levels seem to be lower than the acceptable levels by WHO/FAO, due to bioaccumulation of cadmium in fish could not be tolerated and the consumers might raise alarm if they were actually aware of its potential health risks.…”

“…The level of MRLs exceeded may pose a danger to human health and equally polluting environmental in Nigeria. Akoto et al (2013) also found out in their study that, the degree of pesticides residue contamination in maize and cowpea sampled in Ejura town exceeded the European Union MRLs. Their findings however show that, maize was highly contaminated with total of 0.087mgkg -1 and 0.075mgkg -1 for organochlorine, organophosphates and pyrethroid pesticides, respectively.…”

“…The high levels of pesticide toxicants found in the country are 240-650 µg/m 3 (1040 µg/m 3 ) for endosulfans and hexachlorobenzene from 120 to 2890 µg/m3 (mean 790 µg/m 3 ). However, at southern Nigeria, it reported lower level of Chlordane and endosulfans (AKOTO et al, 2013). In places such as in Lake-Gerio and River Benue (In Adamawa state, Nigeria) where insecticides never been used for control of vectors, even surface water samples contained pesticide toxicant.…”

“…The residues enters natural water from direct application for control of aquatic weeds, trash fish, aquatic insects, percolation and run-off from agricultural production fields, drift from agro-allied industrial waste water and discharge from waste waters from clean-up equipment's used for pesticide formulation and application (OKENIYIA et al, 2009). Akoto et al (2013) found in their studies that high level of chlorinated pesticides was as a result of extensive use of Lindane in fishing and Aldrin in cultivated fields close to these lakes, rivers and wells around. Osibanjo (2002) postulated that, the occurrence of OCP in major rivers in Nigeria which serves as a source of drinking water to the vast majority of population in the country and also for domestic and industrial purposes.…”

Pesticide helps to enhance agricultural production, however, it significantly affect both socio and environmental entities of a country. In Nigeria, pesticide is widely used, thus its traces have been detected in water, soil and air. Several studies have already indicated that most of the environmental ecology (air, water, and soil) in Nigeria has been contaminated by persistent organic pesticides like organochlorine and organophosphate. Other reasons of high pesticide residues present in Nigeria environment is due to inappropriate dosage applied of pesticides that leaves behind excess. However, its residues are found above safety levels in the air, water, and soil across the nation. Based on previous analysis, it is indicated that 125,000-130,000 metric ton pesticides are being applied annually in Nigeria. Despite banned of some pesticides such as dichlorodiphenyltrichloroethane-and -Hexachlorocyclohexane, they are still being used by farmers in their agricultural production. Many of the Class 1 (high extremely toxic) pesticides are still being used in developing countries like Nigeria. Hence, there is need to sensitize and educate the general public especially the end-users (farmers) particularly on management practices of pesticides. Considering these entire hazardous situations, in this article the history of pesticide used in Nigeria has been reviewed in detail. The article also discussed the effects of pesticide use in Nigerian waters, soil and on crops. The risk of residual pesticide on agricultural workers, pesticide residue risk preventive measures by the Federal Government of Nigeria, banned and restricted pesticides in Nigeria, Nigerian Government and its efforts to eliminate persistent organic pesticides in use are also reviewed in details.

ResumoInseticidas ajudam a aumentar a produção agrícola, no entanto, afetam significativamente a sociedade e o ambiente do país. Na Nigéria, os inseticidas são amplamente utilizados, assim, seus resíduos foram detectados na água, solo e ar. Vários estudos já indicaram que a maior parte dos aspetos ecológicos ambientais (ar, água e solo) na Nigéria tenham sido contaminados por pesticidas orgânicos persistentes como os organoclorados (OCL) e organofosforados (OP). Outro motivo relacionado com a ocorrência de resíduos elevados de inseticidas presentes no meio ambiente na Nigéria é devido às dosagens inadequadas aplicadas de pesticidas que são aplicados em excesso. No entanto, seus resíduos são

Improved analysis of propamocarb and cymoxanil for the investigation of residue behavior in two vegetables with different cultivation conditions

BACKGROUND A modified quick, easy, cheap, effective, rugged and safe (QuEChERS) method was developed for the simultaneous determination of highly water‐soluble propamocarb and hydrophobic cymoxanil in potato tuber and tomato fruit. Residue behaviors of the fungicides in open field or greenhouse were investigated for the safety evaluation of these two pesticides, and the effects of cultivation conditions, fungicide exposure and fruit size of tomato on residue level are discussed. RESULTS Vegetable samples were extracted with ammonia–acetonitrile, further purified with multiwall carbon nanotubes and analyzed using high‐performance liquid chromatography tandem mass spectrometry. The method was validated with fortified samples at different concentration levels (0.05–2.0 mg kg−1). Average recoveries ranged from 84 to 111% with relative standard deviations between 0.3 and 5.5%. Limits of quantification (LOQs) were set at the lowest spiking level of 0.05 mg kg−1. In tomato and cherry tomato, initial residue level of cymoxanil was below LOQ at recommended good agricultural practices. Propamocarb residues were affected by the cultivation conditions, with highest levels of 0.52 and 0.72 mg kg−1in open field and greenhouse, respectively. In addition, residues of propamocarb in cherry tomatoes were found to be present at 1.25 mg kg−1. CONCLUSIONS The field trial results showed that propamocarb and cymoxanil residues in potato tubers were below LOQ due to the tubers not being exposed to sprayed pesticides. The unexpected high residue levels in cherry tomato seem to indicate that cherry tomato with small size presents certain accumulative effects of propamocarb. © 2020 Society of Chemical Industry
