School Pesticide Exposure
A study published in JAMA July 2005 found that pesticide exposure at school produce acute illness in both the children and school employees. The authors recommended that integrated pest management programs are used in schools and that practices to reduce effect from spray drift, and spray buffer zones around schools are adopted.

Pesticides and Children
Health risks associated with pesticides include cancer and acute and chronic injuries to the respiratory, reproductive, immune and endocrine systems. Children are at particular risk as their dose per body weight is usually much higher and they consume more fruit and fruit juices than adults.
v Infants and young children breath more rapidly than adults
v Behavioural characteristics of children
o1st years young child spends time close to the ground and can be exposed to toxicants in dust, soil and carpets, as well as pesticide vapours in low lying layers of air
oChildren play on the floor, grass, playground - lead based paint dust, cleaning product residues, horticultural chemicals (fertilisers, herbicides, pesticides)
ohand to mouth behaviours
vDeveloping metabolic systems lead to decreased ability to detoxify and excrete toxins.
vChildren absorb nutrients from the gastrointestinal tract differently from adults and depends on differing requirements Ex high calcium absorption for bone growth. Lead is absorbed more readily from the gut than adults, and where an adult will absorb 10% of ingested lead, young children will absorb 50%.
vImmature protective mechanisms – immune system, blood-brain barrier.
Acute effects of exposure include eye and throat irritation, skin rashes, nausea, vomiting, diarrhea, headaches, flu-like symptoms, upper respiratory distress and in extreme cases death.
Chronic effects that appear long after exposure include an increased risk of some types of cancer, reproductive impairment and neurological damage.
