طور باحثون نهجاً محسناً لاختبار الهيدروكربونات العطرية متعددة الحلقات (PAHs)، والتي يمكن أن تتكون في الأطعمة المطهية في درجات حرارة عالية.
اختبرت دراسة أجريت عام 2025 في قسم علوم وتكنولوجيا الأغذية بجامعة سيول الوطنية للعلوم والتكنولوجيا طريقة "QuEChERS" على أنواع متعددة من الأطعمة. وقام الفريق، بقيادة البروفيسور جون-غو لي، بقياس ثمانية أنواع محددة من الهيدروكربونات العطرية متعددة الحلقات، ووجد أن أعلى مستوياتها كانت في زيت فول الصويا، يليه لحم البط وزيت الكانولا.

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.
New research from the University of Notre Dame shows how PFAS chemicals move through the Great Lakes ecosystem and into people. The peer-reviewed study, published this spring, analyzed 42 years of data from nearly 2,500 samples across the food web.

Researchers have found that hydrogen radicals generated by intense ultraviolet light can degrade PFAS forever chemicals. The discovery, led by a team at Aarhus University, points to a potential path for destroying these persistent pollutants rather than merely removing them from water.
A major analysis of more than 5,000 pregnancies has detected an average of 45 chemicals in maternal urine samples, with several tied to shorter pregnancies and lower birth weights. The findings, published in JAMA Network Open, suggest that some replacement substances may carry similar concerns to the chemicals they replaced.
