Pesticide Mixtures Induce Immunotoxicity: Potentiation of Apoptosis and Oxidative Stress
… the following concentrations were chosen for the pesticide mixture studies: 70μM lindane (Lind), 50μM malathion (Mal) and 55μM PBO. In the AlamarBlue cytotoxicity assay, individual pesticide and mixtures of malathion/PBO (MP) and malathion/lindane (ML) prompted cytotoxicity with varying …

Immunotoxicity of Pesticide Mixtures and the Role of Oxidative Stress
The immunotoxic effects of multiple pesticide exposure were evaluated. C57BL/6 mouse thymocytes were exposed to lindane, malathion, and permethrin, either separately or in mixtures of two pesticides, in concentrations ranging from 37.5 uM to 1mM. These exposures caused both apoptotic and necrotic …

Pesticides and Pesticide Mixtures Induce Neurotoxicity: Potentiation of Apoptosis and Oxidative Stress
… (zinc-ethylene-bis-dithiocarbamate) are used as pesticides on a variety of crops worldwide and pose potential health risks to humans and animals. Both endosulfan and zineb are known to affect nervous system. Because the dopaminergic system continues to develop postnatally, we hypothesized that …

Determining The Occurrence, Fate, And Effects Of Pesticide Mixtures Using The Aquatic Amphipod Hyalella Azteca
… rarely occur as single compounds but, rather, as mixtures. In aquatic ecosystems, mixtures of these compounds are often complex, sometimes containing dozens of compounds across a number of different chemical classes. Non-target aquatic organisms are frequently exposed to varying levels of …

Bulk deposition of pesticide mixtures in a Canadian prairie city and the influence of soil temperature fluctuations on 17β-estradiol mineralization
Tests were conducted for 71 pesticides in weekly bulk (wet + dry) deposition samples collected from May 25 to September 21 over two years at two sites in the City of Winnipeg, Canada. Twenty-one pesticides and their metabolites were detected in this study and 99% of samples collected contained …

Effects of Atrazine and Metolachlor on Snails, Tadpoles, and Their Trematode Parasites
The widespread use and subsequent release of pesticides into aquatic environments have sparked concerns about how organisms within these aquatic systems are affected by pesticide pollution. While many studies have examined the effects of pesticides on individual organisms, in a series of …
