“…For epidemiological research and risk management, good knowledge of the exposure situation is needed. Presented examples included seasonal variations in air concentrations of 27 organochlorine pesticides (OCPs) and 25 current-use pesticides (CUPs) [ 72 ], the water concentrations of 53 pesticides in catchments across three agricultural areas of South Africa [ 73 ], and in-depth studies on personal exposure using silicon wristbands for children and guardians during spraying season [ 74 , 75 ]. From concurrently sampled air and soil samples, it was concluded that, except for chlorpyrifos, soil ingestion generally represented a minor exposure pathway compared to inhalation (i.e., <5%) [ 76 ].…”

Despite the fact that several cases of unsafe pesticide use among farmers in different parts of Africa have been documented, there is limited evidence regarding which specific interventions are effective in reducing pesticide exposure and associated risks to human health and ecology. The overall goal of the African Pesticide Intervention Project (APsent) study is to better understand ongoing research and public health activities related to interventions in Africa through the implementation of suitable target-specific situations or use contexts. A systematic review of the scientific literature on pesticide intervention studies with a focus on Africa was conducted. This was followed by a qualitative survey among stakeholders involved in pesticide research or management in the African region to learn about barriers to and promoters of successful interventions. The project was concluded with an international workshop in November 2021, where a broad range of topics relevant to occupational and environmental health risks were discussed such as acute poisoning, street pesticides, switching to alternatives, or disposal of empty pesticide containers. Key areas of improvement identified were training on pesticide usage techniques, research on the effectiveness of interventions targeted at exposure reduction and/or behavioral changes, awareness raising, implementation of adequate policies, and enforcement of regulations and processes.

“…A few of the reviewed studies point out the health risks of herbicides (e.g., glyphosate [ 35 ]) and fungicides (e.g., mancozeb [ 24 ]). Most studies focused on the one-exposure one-disease approach, taking into account only single effects of pesticides, while several studies investigating use [ 66 , 67 , 68 ], environmental occurrence [ 56 , 69 , 70 , 71 , 72 ], and human exposure [ 49 , 73 , 74 , 75 ] showed that exposure happens from multiple pesticides over time, which could potentially result in cumulative and synergistic environmental [ 21 ] and public health effects [ 24 , 35 ]. The missing research on multiple pesticides could be due to the challenges with analyzing these pesticides in local laboratories [ 76 , 77 ] and knowledge gaps with data analysis techniques [ 35 ].…”

On the African continent, ongoing agriculture intensification is accompanied by the increasing use of pesticides, associated with environmental and public health concerns. Using a systematic literature review, we aimed to map current geographical research hotspots and gaps around environmental and public health risks research of agriculture pesticides in Sub-Saharan Africa (SSA). Studies were included that collected primary data on past and current-used agricultural pesticides and assessed their environmental occurrence, related knowledge, attitude and practice, human exposure, and environmental or public health risks between 2006 and 2021. We identified 391 articles covering 469 study sites in 37 countries in SSA. Five geographical research hotspots were identified: two in South Africa, two in East Africa, and one in West Africa. Despite its ban for agricultural use, organochlorine was the most studied pesticide group (60%; 86% of studies included DDT). Current-used pesticides in agriculture were studied in 54% of the study sites (including insecticides (92%), herbicides (44%), and fungicides (35%)). Environmental samples were collected in 67% of the studies (e.g., water, aquatic species, sediment, agricultural produce, and air). In 38% of the studies, human subjects were investigated. Only few studies had a longitudinal design or assessed pesticide’s environmental risks; human biomarkers; dose-response in human subjects, including children and women; and interventions to reduce pesticide exposure. We established a research database that can help stakeholders to address research gaps, foster research collaboration between environmental and health dimensions, and work towards sustainable and safe agriculture systems in SSA.

“…Also, such samplers allow time-averaged concentrations (TWA) determination in locations where active samplers would not be practical over long periods due to a lack of electricity supply. As a result of their simplicity and practicality, passive samplers more frequently are transformed into wearable devices such as badges, brooches, and diffusion tubes for screening ambient pollutants such as PAHs, phthalates [19,26,39,41,45], flame retardants [34,39,41,46], and pesticides [33,38]. Table 2 summarizes various applications reported in the literature after 2020 with active and passive samplers in exposure studies.…”
