Pesticide Study

According to a study by Food News
"people can lower their pesticide exposure by 90 percent by avoiding the top twelve most contaminated fruits and vegetables and eating the least contaminated instead. Eating the 12 most contaminated fruits and vegetables will expose a person to nearly 20 pesticides per day, on average".
What do they say is included in the "dirty dozen"?
