Insights

Cooking fumes, specifically fine particulate matter (PM2.5), pose health risks to cooks. Studies show PM2.5 levels during frying exceed safe limits, indicating a significant non-cancer risk for those exposed.

Area of Science:

  • Environmental Health
  • Occupational Health
  • Air Pollution Science

Background:

  • Particulate matter (PM) is a major indoor and outdoor air pollutant linked to adverse health outcomes.
  • Cooking activities, particularly frying, are significant sources of indoor PM emissions.
  • Assessing the health risks associated with cooking-related PM exposure is crucial for public health.

Purpose of the Study:

  • To measure and estimate PM2.5 levels during potato and meat frying.
  • To assess the non-carcinogenic health risks associated with PM2.5 exposure for cooks.
  • To compare PM2.5 levels and associated risks using different cooking oils.

Main Methods:

  • Quantification of PM2.5 concentrations (μg/m³) during potato and meat frying at 150-240 °C using sunflower and frying oils.
  • Calculation of Hazard Quotients (HQ) to evaluate non-carcinogenic risk.
  • Analysis of PM2.5 levels and HQ values based on mean and range.

Main Results:

  • PM2.5 levels during potato frying ranged from 20-210 μg/m³ (mean 50.28) with sunflower oil and 20-180 μg/m³ (mean 46.94) with frying oil.
  • PM2.5 levels during meat frying ranged from 20-320 μg/m³ (mean 73.61) with sunflower oil and 20-280 μg/m³ (mean 68.9) with frying oil.
  • Mean Hazard Quotients exceeded the acceptable limit of 1 for both potato and meat frying, indicating health risks.

Conclusions:

  • Cooking activities, especially frying, generate PM2.5 levels that pose a non-cancer health risk to cooks.
  • The use of different oils (sunflower vs. frying oil) did not significantly alter the risk levels.
  • Implementing mitigation strategies is recommended to reduce cook exposure to harmful PM2.5 emissions.
