harmful affects then positive affects on
human heath and environmental vitality
Quick Fact:Only 5 percent of pesticides reach targeted weeds, the rest runs off into water or into the air where it can drift from 12 feet to 14.5 miles away
The pesticide is absorbed by the soil
The pesticides chemical structure changes
There are three main transformation processes
Pesticide is transported most commonly by mass flow and diffusion
4. Plant Uptake
The process of pesticide being taken into the plant, where it now resides inside the plants internal structure
- children have more rapid breathing
- metabolic rates
- greater surface to body mass ratios
- thinner skins
- spend more time in contact with the ground
- more frequently place their fingers in their mouths
Quick Fact:Children whose homes and gardens are treated with pesticides have 6.5 times greater risk of leukemia than children living in untreated environments.
- especially those with asthma, lupus erythematosus, vacuities, dermatitis and chemical sensitivities
- pets, wildlife of all kinds and their habitat
Main risks for adults
Main risks for children
cancer: leukemia and brain cancer
asthma and allergies
polyneuritis with numbness and pain in lower limbs.
gangrene (tissue death) of the extremities
Animals may develop
abnormal thyroid function
decreased hatching success
demasculinization and feminization of males
alteration of immune function
