Researchers have developed an improved testing approach for polycyclic aromatic hydrocarbons, or PAHs, which can form in foods cooked at high temperatures.
A 2025 study from the Department of Food Science and Biotechnology at Seoul National University of Science and Technology tested the QuEChERS method on multiple food types. Led by Professor Joon-Goo Lee, the team measured eight specific PAHs and found the highest levels in soybean oil, followed by duck meat and canola oil.

Preliminary research from USC Norris Comprehensive Cancer Center, presented at the American Association for Cancer Research (AACR) annual meeting, found that non-smokers diagnosed with lung cancer before age 50 reported eating more fruits, vegetables and whole grains—and had higher overall Healthy Eating Index scores—than the U.S. population average. The researchers emphasized that the results do not prove diet causes lung cancer and said a possible explanation could involve environmental exposures such as pesticides, a hypothesis that requires direct testing.
A study published in *Nature Health* reports a statistical link between environmental exposure to mixtures of agricultural pesticides and higher cancer risk in Peru. Using modeled pesticide dispersion from 2014 to 2019 and cancer registry data from 2007 to 2020 covering more than 150,000 cases, researchers found that people living in high-exposure areas faced, on average, about a 150% higher likelihood of cancer, with Indigenous and rural farming communities among those most exposed.

Nearly one in 10 homes tested in the UK, Italy and the Netherlands showed benzene levels from gas cooker leaks that surpass safety limits, according to researchers. The cancer-causing chemical in natural gas poses risks akin to secondhand smoke indoors. The findings highlight potential indoor air pollution from slow leaks.
