Twenty five minerals and trace elements were determined by flame atomic absorption spectrometry and inductively coupled plasma mass spectrometry in 64 pooled foods prepared 鈥渁s consumed鈥? representing 96.5% of the total diet in Yaound茅, Cameroon. High element contents (in mg kg^鈭?) of some food samples are highlighted. 鈥淒ried spices for local sauce鈥?(raw/toasted) highly contained calcium (7720), iron (143), magnesium (1970), potassium (20,100), copper (12.6), manganese (109), aluminium (120), and lead (14.3). 鈥淒ried and smoked fish and shrimps鈥?(boiled) contained high levels of calcium (21,200), potassium (7300), zinc (43.6), aluminium (27.8), and arsenic (1.14). 鈥淕arden huckleberry and amaranth鈥?(boiled/washed fresh leaves) contained high levels of calcium (3580), manganese (15.9) and barium (19.4). 鈥淪quash beans and sesame鈥?(boiled) provided magnesium (1240), and zinc (29.5). 鈥淪helled groundnut鈥?(soaked/grilled/boiled) contained high levels of magnesium (1040), zinc (31.5), and copper (8.32). Selenium was found only in fish as mackerel (0.467) and sea bass (0.450). No food product exceeded the maximum levels set for lead, mercury and cadmium by the current European regulation. These results will be used for dietary exposure and health risk assessment.
