These studies are critical to the human risk assessment for crop protection
products. Their purpose is to fully evaluate the nature of the residue, in terms
of parent active substance and metabolites, that may occur in foodstuffs intended
for human or animal consumption. The data are used to define the residue to
be determined in residue field trials or livestock feeding studies.
The rotational or succeeding crop metabolism study is specifically aimed at
investigating the nature of the residue (if any) that may occur in crops grown
in the same soil following a crop that has been treated with the active substance.
Studies offered include:
- Plant metabolism and rotational crop metabolism. We have experience with
many crops including:
- Cereals: wheat, barley, maize, rice
- Fruit: apple, orange, grapefruit, grape, olive, strawberry, melon, tomato,
cucumber, aubergine (egg plant)
- Leafy crops: cabbage, lettuce and other vegetables
- Roots and tubers: potato, sugar beet, carrot, turnip
- Pulses and oilseeds: oilseed rape, soya bean, cotton, pea, bean
- Livestock metabolism: species include lactating and beef cattle, lactating
goats, pigs, sheep and laying hens
- Nature of the residue resulting from processing
- Identification of metabolites
We can offer to synthesise radiolabelled test substances that are always required
for plant and livestock metabolism studies.
