Which Foods Contain the Most Pesticides?
Pesticides are often necessary to keep crops safe, but many consumers have been increasingly concerned about the amount of pesticides and herbicides that remain on the food they purchase. Some foods are more susceptible to exposure to pesticides than others. A team of researchers at Nadrich & Cohen looked at data from the U.S. Food and Drug Administration to see which foods have the most pesticide and herbicide residue. The study looks at both domestic and imported foods.
The visualization utilizes horizontal bar charts to show the percentage of samples that contained pesticide residue. It also uses the same horizontal bars to visualize the percentage of the samples that violated federal standards.
The following are the foods that rank highest for most herbicide/pesticide residue for both domestic and imported foods:
- Raspberry fruit/juice: 95.8%
- Peach fruit/juice: 92.9%
- Cucumbers: 85.2%
- Hot peppers: 85.1%
- Celery: 83.9%
- Potatoes: 83.3%
- Spinach: 82.2%
- Pear fruit/juice: 81.8%
- Kale: 80.1%
- Cilantro: 77.8%
In terms of domestic foods, 100% of samples of these foods had pesticide and/or herbicide residue: orange juice/fruit, cherry fruit/juice, broccoli, spinach, raspberry fruit/juice, hot peppers, apricot fruit/juice, peach fruit/juice, rice/rice products, and cucumbers.
These are the foods that have the lowest rate of herbicide/pesticide residue for domestic and imported foods:
- Cauliflower: 6%
- Asparagus: 7.2%
- Cranberry fruit/juice: 23.1%
- Mushrooms and truffles: 26.1%
- Oats and oat products: 26.7%
- Edible seeds and seed products: 27.8%
- Corn and corn products: 32.2%
For domestic foods, none of the samples had herbicide or pesticide residue: cabbage, cauliflower, radishes, red beets, and asparagus.

Visualizing the Cost Per Ounce of the World’s Most Valuable Metals
The team at Kylar Mack shows us just how valuable the world’s most precious metals are with this illustrated chart visualizing the cost per ounce of the most expensive metals and alloys. A metal is naturally occurring, and many appear on the periodic table of elements whereas an alloy combines two elements.
On this illustrated chart, we can truly visualize the comparative value of these metals because the team stacked money representative of the value beside an image of each metal. The chart is a great example of the power of visual data. Our eye is immediately drawn to the vast stacks of cash beside the most valuable metal, Californium. These stacks tower above ever other metal on the chart making it clear that not all metals are created equal.

Californium’s value is a shocking $765,436,299 per ounce! That’s significantly higher than the second-most popular metal, a non-synthetic called Iridium, which is valued at $4,700. The key to the value difference lies in the fact that Californium is a synthetic substance. It’s created in a nuclear reactor and only two plants in the world have the capability of engineering it. As for Iridium, it’s naturally occurring but hard to mine and access. It’s found deep under the Earth’s crust, often attached to asteroids. Through this chart, we can learn more about different metals as well as why they’re so highly valued. Many are needed for key electronics and aerospace parts.
