Investigadores han desarrollado un enfoque de análisis mejorado para los hidrocarburos aromáticos policíclicos (HAP), los cuales pueden formarse en alimentos cocinados a altas temperaturas.

Un estudio de 2025 del Departamento de Ciencia y Biotecnología de los Alimentos de la Universidad Nacional de Ciencia y Tecnología de Seúl evaluó el método QuEChERS en diversos tipos de alimentos. Dirigido por el profesor Joon-Goo Lee, el equipo midió ocho HAP específicos y encontró los niveles más altos en el aceite de soja, seguido por la carne de pato y el aceite de canola.

Study of young lung cancer patients finds unexpectedly high diet-quality scores; researchers probe possible pesticide exposure

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.

Study maps pesticide mixtures in Peru and finds higher cancer risk in high-exposure areas

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.

Benzene leaks from gas cookers exceed safety limits in European homes

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.
