Evaluation of heavy metal content in plastic bags used as part of food cooking containers: a socio-educational sustainability perspective in Mozambique

Ver documento

Detalhes bibliográficos
Resumo:In Mozambique, rudimentary food preparation practices are still common. A common habit is the use of plastic bags for preparing foods such as tubers, meat and rice, particularly among families with relatively low financial resources. These bags are often used because they are cheap, easy to handle, flexible and offer good thermal insulation. Nevertheless, the practice of using plastic bags in cooking raises serious public health concerns. This is due to the fact that many of these plastics contain heavy metals added during manufacturing to improve their physical and chemical properties. When heated, these metals can migrate into food, posing a significant health risk. Among the most worrying metals are cadmium (Cd), lead (Pb), mercury (Hg), chromium (Cr), zinc (Zn), copper (Cu), nickel (Ni) and arsenic (As).
