“…These include: abamectin, chlordane, dieldrin, endosulfan and aldrin. Similar studies in developing countries reveals heavy use of pesticides in farming with much use of organochlorine pesticides as revealed in a number of previous studies [12]; [13]; [14].…”

Pesticides and fertilizers use in parts of Rivers Niger and Kaduna catchments, north central, Nigeria was investigated. Contamination of the rivers and their resources due to unsustainable use of pesticides and fertilizers by local farmers are a major problem in the study area. Also, data from the study of pesticides and fertilizer use remain scanty and therefore needed. The objective is to find the opportunity for all stakeholders to improve on the overall environmental performance. Extensive field survey was conducted using various participatory appraisals techniques involving key stakeholders in the area. Collated data were analysed using descriptive statistical methods (frequency percentage). The results of findings identify unsustainable use of fertilizers and pesticides by farmers in the study area. It further shows respondents in the study area applied high rate of fertilizers and pesticides during farming activities which obviously improved crop yield but in turn lead to water quality degradation. Virtually, majority of the farmers have little or no measures towards ensuring protection of water and biota from the potential danger of pesticides and fertilizers use in the study area. These attitudes discovered could lead to water quality degradation, biodiversity disruption and subsequent negative impact on economic development in the study area. In view of the above, it is recommended that visible and effective environmental management policies in respect of agrochemicals use in the study area be put in place to guarantee cleaner and healthier environment for all.

“…For example, in the KwaZulu Natal Province within South Africa, Buah‐Kwofie et al. ( 2019 ) reported high concentrations of DDT, DDD and DDE in the 5.1–19 ng/g in spinach, peanut, onion, and lettuce samples while Nuapia et al, 2018 recorded concentrations between 61.05 and 125.87 µg/kg in cabbage samples from open markets in Johannesburg, South Africa and Kinshasa, Democratic Republic of Congo (Nuapia et al, 2016 ). In Togo, the concentrations were up to 643 ng/kg in cabbage and 527 and 681 ng/kg in tomato and lettuce samples, respectively (Kolani et al., 2016 ).…”

“…Organochlorine pesticide residues are persistent and continuous application of such pesticides can lead to higher pesticide residue levels in the soil and subsequent uptake by plants which possibly will ensue in pesticide residue levels causing health hazards to be manifested (Taiwo, 2019 ). Elsewhere within South Africa, some of the organochlorines have been found to be associated with cancer risks, notably aldrin and dieldrin in vegetables of the KwaZulu natal Province (Buah‐Kwofie et al., 2019 ), DDT and hexachlorobenzene in vegetables around Johannesburg markets (Nuapia et al, 2016 ). Across Africa, the presence of pesticides in vegetables has been found to be of potential health risk to consumers in Togo (Kolani et al., 2016 ) and the DR Congo (Nuapia et al, 2016 ) while in Burkina Faso, the vegetables had no risk to the consumers (Lehmann et al, 2017 ).…”

Food safety has become a primary public concern worldwide, due to pesticide residues in food resulting from direct application of pesticides to crops. Pesticides are mainly applied in the farming industry to control vectors that reduce the quantity and quality of farm produce.The pesticides are sprayed directly on the crops/vegetables and the soil surface. Some pesticide residues are persistent and can remain on the surface of the crops and/or absorbed from soil into the plant system. Consumption of farm produce, therefore, becomes the primary source of exposure of the general population to pesticides. The pesticide metabolites in the human body have been linked to a wide variety of health effects, ranging from acute to chronic toxicity; such as cancer, endocrine disruption, and neurological effects (Taiwo, 2019).

“…GC–MS/MS was widely used in multi-analysis, working in SRM, MRM, and SIM modes. Buah-kwofie et al [ 78 ] analyzed OCP residues from vegetable samples by two-dimensional gas chromatography/time-of-flight-mass spectrometry (GC × GC–TOF-MS). In addition, GC–microeletron captutre detection (µECD) was used in several studies to analyze OCPs, OPPs, and PYRs in food samples of different classes (milk, fish, and vegetables).…”

Background: Pesticide residues are a threat to the health of the global population, not only to farmers, applicators, and other pesticide professionals. Humans are exposed through various routes such as food, skin, and inhalation. This study summarizes the different methods to assess and/or estimate human exposure to pesticide residues of the global population. Methods: A systematic search was carried out on Scopus and web of science databases of studies on human exposure to pesticide residues since 2019. Results: The methods to estimate human health risk can be categorized as direct (determining the exposure through specific biomarkers in human matrices) or indirect (determining the levels in the environment and food and estimating the occurrence). The role that analytical techniques play was analyzed. In both cases, the application of generic solvent extraction and solid-phase extraction (SPE) clean-up, followed by liquid or gas chromatography coupled to mass spectrometry, is decisive. Advances within the analytical techniques have played an unquestionable role. Conclusions: All these studies have contributed to an important advance in the knowledge of analytical techniques for the detection of pesticide levels and the subsequent assessment of nonoccupational human exposure.
