Soil is the final depot of most environmental contaminants, including pesticides. Soil may be contaminated by pesticides as a result of direct application or drift during spray activities. Soil contamination with pesticide residues may affect the quality of food crops, animal products, and soil micro-organisms which may in turn negatively affect human health and the environment. Objectives. The main objective of the current study was to determine the soil residues of commonly used pesticides in rain-fed crops grown by the Nuba Mountains Cotton Corporation (NMCC) in South Kordofan state of Western Sudan. Methods. Four locations (representing the four directions around the state capital Kadugli) were chosen for sample collection: Alefain (East Kadugli), Elmashaish (West Kadugli), Ed Dalling uncultivated area (North Kadugli) and Lagawa (Southwest Kadugli). Nine soil samples were randomly taken from each location representing areas under cotton, sorghum, and uncultivated land covered with natural vegetation. Soil samples were analyzed by gas chromatography (GC) equipped with electron capture detector (ECD) and GC-mass spectrometry (MS). Results. The results generally indicated that organophosphate levels were greater than organochlorine and pyrethroids with heptachlor, malathion, and dimethoate present in all samples analyzed, while the level of p,p-dichlorodiphenyltrichloroethane (DDT) was below the detection limit. Endosulfan α and β isomers were detected in some samples. Dimethoate had the highest level (22.02 mg/kg), while β endosulfan was found at the lowest level (0.015 mg/kg). Generally, samples collected from cotton soils showed higher residue levels compared to sorghum soil with average concentrations of 307.25 mg/kg versus 58.63 mg/kg, respectively. Almashaish showed the highest residues levels followed by Alefain, Lagawa, and Ed Dalling with total residues of 57.56 mg/kg, 26.34 mg/kg, 22.63 mg/kg, and 17.07 mg/kg, respectively. Conclusions. The current study sheds light on the residue levels of some of the commonly used pesticides in the cotton rain-fed scheme in South Kordofan State, western Sudan. The study calls for regular residue monitoring in various environmental components in the area and suggests possible management measures. Competing Interests.

Ethiopia is the second most populous nation in Africa with around 80% of the population still depending on agriculture which intensively uses pesticides. A number of studies have examined pesticide-related health and environmental risks in Ethiopia. However, most of these studies have been small in scale and it is therefore challenging to get a general overview of the extent of health risks and level of environmental contamination in the country.</p><p><strong>Objectives: </strong>The aim of the present study was to synthesize and summarize contemporary knowledge on pesticide-related risks and relevant gaps in Ethiopia.</p><p><strong>Methods: </strong>An electronic database search and gathering of grey literature were done to collect information on the risks of pesticide use in Ethiopia.

In addition, there have been frequent reports of health and environmental hazards in association with cut-flower farms. There is also evidence of direct use of DDT (dichlorodiphenyltrichloroethane) on food crops and detection of DDT residues in surface water, soil and human breast milk. Those reported risks might be due to lack of knowledge among farm workers, negligence of farm owners, absence of post-registration monitoring systems and poor implementation of both national and international regulations in Ethiopia due to poor institutional capacity.</p><p><strong>Conclusions: </strong>The health and environmental risks of inappropriate use of pesticides requires action by all concerned bodies.

A total of 236 households were surveyed, including waste collectors and cleaners, waste pickers, and 20 students and ten teachers from Woldia secondary and preparatory schools. A purposive sampling technique (made up of municipal officers, scavengers (waste pickers), waste collectors and cleaners and a simple random sampling technique (of teachers, students and <i>kebeles</i> of the study area) was employed, then proportional allocation was made for each randomly selected <i>kebeles</i> based on population size to determine the sample. Finally, survey questionnaire, interview, focus group discussion and observation were used as data collecting tools.

Additionally, shortage of storage materials, lack of alternative waste disposal options, household attitudes, and lack of awareness were the major challenges for low performance of solid waste management practices of the local government and households. The focus group individuals and interviewed participants indicated that solid waste management practices were poor.</p><p><strong>Conclusions: </strong>The present study revealed that solid waste management practices in Woldia town remain inadequate. Therefore, efforts by the municipality and other stakeholders are needed to mitigate the problem of waste management and disposal practices.</p><p><strong>Participant consent: </strong>Obtained.</p><p><strong>Ethics approval: </strong>The study was approved by the Institutional Research Ethics Review committee (IRERC) of Woldia University.</p><p><strong>Competing interests: </strong>The authors declare no competing financial interests.</p>","PeriodicalId":52138,"journal":{"name":"Journal of Health and Pollution","volume":"11 30","pages":"210605"},"PeriodicalIF":2.4,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8276726/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39189848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
