BACKGROUND Pesticide self-poisoning causes one third of global suicides. Sri Lanka halved its suicide rate by banning WHO Class I organophosphorus (OP) insecticides and then endosulfan. However, poisoning with Class II toxicity OPs, particularly dimethoate and fenthion, remains a problem. We aimed to determine the effect and feasibility of a ban of the two insecticides in one Sri Lankan distric...
Background: Agrochemicals are widely used in many parts of the world posing direct and indirect threats to organisms. Xenobiotic-related disease susceptibility is a common phenomenon and a proposed cause of amphibian declines and malformations. For example, parasitic infections combined with pesticides generally pose greater risk to both tadpoles and adult frogs than either factor alone. Here, ...
Research has documented the effects of tankmixing glyphosate with numerous insecticides on cotton growth and yield; however, no information is available concerning the addition of a residual herbicide such as an aqueous capsule suspension (ACS) formulation of pendimethalin to glyphosate plus an insecticide. Mixtures such as this are important as producers continue to search for costs savings in...
In utero and lactational exposure to organophosphate dimethoate exerted toxic impact on the reproductive system of male mice. Pregnant mice were exposed to 4, 8, and 16 mg/kg of the pesticide, the sublethal doses (2.5, 5, and 10% of Lethal Dose(50) [LD(50)]), via gavaging from gestation day (GD) 6 to postnatal day (PND) 21. The effects on the male reproductive system were evaluated at two stage...
This chapter provides a review and evaluation of the literature pertinent to joint toxic action of the mixture and its components. 2.1 Mixture of Concern Toxicological data or PBPK models were not available for the complete mixture of concern. Toxicological and mechanistic data, but no PBPK models, were available for all of the binary mixtures, but were limited. For some binary mixtures, few or...
Pollinators in agricultural landscapes can be exposed to mixtures of pesticides and environmental pollutants. Existing mixture toxicity modelling approaches, such as the models of concentration addition and independent action and the mechanistic DEBtox framework have been previously shown as valuable tools for understanding and ultimately predicting joint toxicity. Here we apply these mixture m...
