Chemical pesticides are widely used in Cameroon for agricultural production. In 2015, more than 600 pesticide products were approved for use in various foodstuffs. Much misuse of these chemicals by farmers has been documented in rural and urban settings. This pilot study aims to contribute to the improvement of the health of the population and the environmental preservation by identifying pesti...
Occupational exposure to pesticides in agricultural applications may cause acute and long-term health effects to farmers, and thus research on factors that reduce exposure is useful. However, studies on the relevance and effectiveness of training are limited. The association of previous training in the form of intensive seminars relating to pesticide use (e.g., use of spraying equipment, applic...
SWATCATCH is a distributed model combined with databases within a GIS as the POPPIE system to predict pesticide concentrations in rivers at the catchment outlet. The model was evaluated against a dataset of pesticide concentrations in rivers of England and Wales. More than 2000 individual analyses in each of the years 1995 and 1997 covered approximately 150 catchment-pesticide combinations draw...
OBJECTIVE This study was conducted to describe the national magnitude and characteristics of acute pesticide poisoning among workers and customers in retail establishments. METHODS Analyses included retail employees 15-64 years of age and customers with acute pesticide poisoning identified from the Sentinel Event Notification System for Occupational Risks-Pesticides (SENSOR-Pesticides) and Ca...
Transport of pesticides by surface runoff during rainfall events is a major process contributing to pesticide contamination in rivers. This study presents an empirical regression model that describes pesticide loading over time in the Sacramento and San Joaquin Rivers. The empirical model is physically based, but uses highly aggregated parameters, allowing the prediction of pesticide loading wi...
The paper analyses trends in consumption, productivity and the determinants of pesticide use in Bangladesh over a 33 year period (1977-2009), including a discussion on the scope to expand Integrated Pest Management (IPM) practices. Pesticide use grew at an alarming rate of 10.0% per year (p<0.01) although the corresponding response in yield growth of major crops has been minimal (<1.0% per year...
The study aims to provide a comprehensive trend of pesticide poisoning cases in the Philippines as well as pesticide exposures, and risk factors related to the adverse effects of pesticide. Records were gathered from the National Poison Control and Management Center (NPCMC), the Philippine General Hospital, De La Salle Medical Center, and other hospitals, and reviewed research studies conducted...
The aim of our study was to investigate the amount of 110 pesticide residues in cereals and foodstuff from Poland as a part of official control. A total of 89 samples were collected in 2009-10. In 84.2% of the samples no residues were found: 15.8% of samples contained pesticide residues below the maximum residue limit. Pirimiphos-methyl was the most frequently found pesticide. The results show ...
Different wipe materials and wetting agents have been traditionally used to collect pesticide residues from indoor surfaces in human exposure assessments. Such methods were developed to estimate human pesticide exposure through skin contact. From an environmental point of view, wiping methods may be also applied to predict the runoff potential of pesticides on urban impervious surfaces. Since l...
The benefits of global pesticide use come at the cost of their widespread occurrence in the environment. An array of abiotic and biotic transformations effectively removes pesticides from the environment, but may give rise to potentially hazardous transformation products. Despite a large body of pesticide degradation data from regulatory testing and decades of pesticide research, it remains dif...
