i don't know, but as @GameOfJones has said Bicarbonate of soda removes a lot of them (something like 66- 99% of pesticides) & because it's slightly abrasive, helps with general cleaning
Arm & Hammer recommends 1 teaspoon per 2 cups of cold water, and swishing your produce in the solution before allowing the produce to soak for 12–15 minutes
however
The USDA consistently studies the levels of pesticide residues on produce in its Pesticide Data Program, but analysis of the data shows that even though pesticides are often detected, the levels are below what would be harmful to consumers. One way of avoiding higher pesticide exposure is to buy organic or locally from farmers markets'
'As an alkaline compound, baking soda will start to break down more delicate fruit and vegetable skins and surfaces after the recommended 12–15 minutes, and can even soften beans and other pulses under longer exposure. This means “sturdy items with smooth skin will hold up the best (apples, pears, some melons and squash, etc.),” says House. Beyond that, studies have shown that while washing produce in a baking soda solution can reduce pesticide residues by 66.7–98.9%, washing in tap water alone can reduce by 26.7–62.9%. Knowing that the levels of pesticide residues are almost negligible anyway, the advantage added by baking soda becomes minuscule'
i think quickly rinsing & washing is probably where you can make the most difference without spoiling your F&V & without too much effort.
plus if you buy British produce it shouldn't have wax coating, so that's one less thing.
