Citaat:What happens to permethrin in the environment?
If permethrin gets into the soil, it is broken down by microorganisms. Sunlight may also break down permethrin on the soil surface and on the surface of water. Permethrin does not mix well with water. When permethrin gets into surface water like lakes or streams, it sticks very strongly to sediment and can stay there for more than a year. Since permethrin sticks to sediment and does not mix well with water, it won't usually contaminate groundwater. Permethrin does not evaporate very easily when it is applied to surfaces. Permethrin was applied indoors near a window in an experiment where it was exposed to daylight. After 20 days, 60% of the permethrin that was applied was still on the surface.
If permethrin is applied to plants, it may stay on the leaves for between 1 and 3 weeks. Scientists applied permethrin to soil and then planted sugar beets, wheat, lettuce and cotton in the soil. Scientists found trace amounts of the permethrin residue in the edible parts of the plants at 30 and 120 days after planting. Trace amounts of permethrin have been found in foods including bananas, collard greens, squash and watermelon. However, less than 1% of the more than 1,700 food samples tested had detectable levels of permethrin.
Can permethrin affect birds, fish, or other wildlife?
Permethrin is highly toxic to fish and other animals that live in either salt water or fresh water. Permethrin is low in toxicity to birds, but some aerosol products made with permethrin may also contain other ingredients that can harm birds if they inhale it. Permethrin is highly toxic to bees and other beneficial insects.

Het is giftig voor alle insecten, dus ook de insecten die we hard nodig hebben en die het al niet te best hebben. Daarnaast is het ook schadelijk voor ander waterleven en ook katten zijn kwetsbaar.Citaat:What happens to permethrin in the environment?
