Bioaccumulation in organisms
Toxicokinetics of pesticides in arthropods
Cause
Secondary
Through topic interactions
Parasitic
Predaions
Primary
Exposure
To
Crop protection products
Herbicides
Insecticides
Pesticides
Fungicides
By
Oral
Drinking contaminated water
Feeding
Treated plants
Contaminated Nectar
Other ways of being exposed
Skin
Cuticule
Respiratory
Effects
It can cause
Damage tissue
Reduce
Fitness/displacement capacities
Probably result in death because they are more easily prayed.
It can also affect the predators that hunt this arthropods.
Biomagnification of the problem
It depends of
The bioavailability of the pesticides
The absorption that each species has
Different sensitivity to pesticides is caused by
The species of the arthropods
Between the same species
Weight
Age
The stage that it is in their lifespan
Resistance and detoxification
Resistance mechanisms
Target-size mutations
Transgenerational changes
Such as
Upregulation of detoxification genes
Avoidance
Specific gut microorganisms
Detoxication capacity is affected by
Health status
Its inmunity
Age
Co-exposition to other hazards
Concepts
Bioaccumulation
It is the accumulation of a substance because they enter an organism faster that they can dispose it.
Trophic transfer
It is the transfer of substances from different trophic levels.
Trophic transfers effects
Parasites
Disruption of reproduction
At the moment of the insertion of their eggs
Predators
Pesticide induce mortality
around 30-40% increase
Altered behaviour
Hunting ability
Slower movement
blockage of nicotinic acetycholine receptor
High trophic levels
Secondary poisoning in small vertebrates
Mainly in small mammals and birds
