Pesticide	toxicity also depends rate absorption distribution within body metabolism elimination compounds body.commonly used pesticides like organophosphates carbamates act inhibiting acetylcholinesterase activity prevents breakdown acetylcholine neural synapse.excess acetylcholine lead symptoms like muscle cramps tremors confusion dizziness nausea.studies show farm workers ethiopia kenya zimbabwe decreased concentrations plasma acetylcholinesterase enzyme responsible breaking acetylcholine acting synapses throughout nervous system.studies ethiopia observed reduced respiratory function among farm workers spray crops pesticides.
Pesticide	numerous exposure pathways farm workers increase risk pesticide poisoning including dermal absorption walking fields applying products well inhalation exposure.measuring exposure pesticides multiple approaches measuring persons exposure pesticides provides estimate individuals internal dose.two broad approaches include measuring biomarkers markers biological effect.former involves taking direct measurement parent compound metabolites various types media urine blood serum.biomarkers may include direct measurement compound body it’s biotransformed metabolism.
Pesticide	suitable biomarkers may include metabolites parent compound they’ve biotransformed metabolism.toxicokinetic data provide detailed information quickly compound metabolized eliminated body provide insights timing exposure.markers biological effect provide estimation exposure based cellular activities related mechanism action.example many studies investigating exposure pesticides often involve quantification acetylcholinesterase enzyme neural synapse determine magnitude inhibitory effect organophosphate carbamate pesticides.another method quantifying exposure involves measuring molecular level amount pesticide interacting site action.methods commonly used occupational exposures mechanism action better understood described guidelines published “biological monitoring chemical exposure workplace.better understanding pesticides elicit toxic effects needed method exposure assessment applied occupational exposure agricultural workers.
Pesticide	alternative methods assess exposure include questionnaires discern participants whether experiencing symptoms associated pesticide poisoning.selfreported symptoms may include headaches dizziness nausea joint pain respiratory symptoms.challenges assessing pesticide exposure multiple challenges exist assessing exposure pesticides general population many others specific occupational exposures agricultural workers.beyond farm workers estimating exposure family members children presents additional challenges may occur “takehome” exposure pesticide residues collected clothing equipment belonging parent farm workers inadvertently brought home.children may also exposed pesticides prenatally mothers exposed pesticides pregnancy.
Pesticide	characterizing children’s exposure resulting drift airborne spray application pesticides similarly challenging yet well documented developing countries.critical development periods fetus newborn children nonworking populations vulnerable effects pesticides may increased risk developing neurocognitive effects impaired development.while measuring biomarkers markers biological effects may provide accurate estimates exposure collecting data field often impractical many methods sensitive enough detect lowlevel concentrations.rapid cholinesterase test kits exist collect blood samples field.conducting large scale assessments agricultural workers remote regions developing countries makes implementation kits challenge.cholinesterase assay useful clinical tool assess individual exposure acute toxicity.
Pesticide	however considerable variability baseline enzyme activity among individuals makes difficult compare field measurements cholinesterase activity reference dose determine health risk associated exposure.another challenge researchers face deriving reference dose identifying health endpoints relevant exposure.epidemiological research needed identify critical health endpoints particularly among populations occupationally exposed.prevention minimizing harmful exposure pesticides achieved proper use personal protective equipment adequate reentry times recently sprayed areas effective product labeling hazardous substances per fifra regulations.training highrisk populations including agricultural workers proper use storage pesticides reduce incidence acute pesticide poisoning potential chronic health effects associated exposure.
Pesticide	continued research human toxic health effects pesticides serves basis relevant policies enforceable standards health protective populations.environmental effects pesticide use raises number environmental concerns.over sprayed insecticides herbicides reach destination target species including nontarget species air water soil.pesticide drift occurs pesticides suspended air particles carried wind areas potentially contaminating them.pesticides one causes water pollution pesticides persistent organic pollutants contribute soil flower pollen nectar contamination.furthermore pesticide use adversely impact neighboring agricultural activity pests drift harm nearby crops pesticide used them.in addition pesticide use reduces biodiversity contributes pollinator decline destroys habitat especially birds threatens endangered species.
Pesticide	pests develop resistance pesticide pesticide resistance necessitating new pesticide.alternatively greater dose pesticide used counteract resistance although cause worsening ambient pollution problem.the stockholm convention persistent organic pollutants listed dangerous persistent organic chemicals mostly obsolete organochlorine pesticides.since chlorinated hydrocarbon pesticides dissolve fats excreted organisms tend retain almost indefinitely.biological magnification process whereby chlorinated hydrocarbons pesticides concentrated level food chain.among marine animals pesticide concentrations higher carnivorous fishes even fisheating birds mammals top ecological pyramid.
Pesticide	global distillation process whereby pesticides transported warmer colder regions earth particular poles mountain tops.pesticides evaporate atmosphere relatively high temperature carried considerable distances thousands kilometers wind area lower temperature condense carried back ground rain snow.in order reduce negative impacts desirable pesticides degradable least quickly deactivated environment.loss activity toxicity pesticides due innate chemical properties compounds environmental processes conditions.example presence halogens within chemical structure often slows degradation aerobic environment.adsorption soil may retard pesticide movement also may reduce bioavailability microbial degraders.
Pesticide	economics one study human health environmental costs due pesticides united states estimated .billion offset billion increased agricultural production.additional costs include registration process cost purchasing pesticides typically borne agrichemical companies farmers respectively.registration process take several years complete different types field tests cost – million single pesticide.beginning st century united states spent approximately billion pesticides annually.resistance use pesticides inherently entails risk resistance developing.
Pesticide	various techniques procedures pesticide application slow development resistance natural features target population surrounding environment.alternatives alternatives pesticides available include methods cultivation use biological pest controls pheromones microbial pesticides genetic engineering methods interfering insect breeding.application composted yard waste also used way controlling pests.methods becoming increasingly popular often safer traditional chemical pesticides.addition epa registering reducedrisk conventional pesticides increasing numbers.cultivation practices include polyculture growing multiple types plants crop rotation planting crops areas pests damage live timing planting according pests least problematic use trap crops attract pests away real crop.
Pesticide	trap crops successfully controlled pests commercial agricultural systems reducing pesticide usage however many systems trap crops fail reduce pest densities commercial scale even trap crop works controlled experiments.release organisms fight pest another example alternative pesticide use.organisms include natural predators parasites pests.biological pesticides based entomopathogenic fungi bacteria viruses causing disease pest species also used.interfering insects reproduction accomplished sterilizing males target species releasing mate females produce offspring.technique first used screwworm fly since used medfly tsetse fly gypsy moth.however costly timeconsuming approach works types insects.
