title: The lead, cadmium and mercury concentrations in muscle, liver and kidney from Finnish pigs and cattle during 1987-1988.
abstract: The lead, cadmium and mercury concentrations in muscle, liver and kidney from Finnish pigs and cattle were determined. The average wet weight lead concentrations in pig muscle, liver and kidney were 15 micrograms/kg, 38 micrograms/kg and 40 micrograms/kg, respectively. The corresponding concentrations for cattle were 13 micrograms/kg, 57 micrograms/kg and 110 micrograms/kg. The average wet weight cadmium concentrations were 1.5 micrograms/kg, 28 micrograms/kg and 170 micrograms/kg (pigs) and 1.3 micrograms/kg, 61 micrograms/kg and 350 micrograms/kg (cattle). The corresponding mercury concentrations were 11 micrograms/kg, 12 micrograms/kg and 14 micrograms/kg (pigs) and 11 micrograms/kg, 12 micrograms/kg and 15 micrograms/kg (cattle). The average concentrations were at or above the detection limit of the metal in question. According to the results obtained by the National Veterinary Institute, the cadmium concentration in pigs and cattle has decreased during the period 1973-1988. The provisional tolerable daily intake of lead/person (60 kg), recommended by GEMS/Food, is 0.43 mg. According to the results for lead levels in these products in Finland, a daily intake of 29 kg pig muscle, 33 kg cattle muscle, 11 kg pig liver, 8 kg cattle liver, 11 kg pig kidney or 4 kg cattle kidney would be required to reach this norm. The corresponding provisional tolerable daily intake of cadmium/person (60 kg) is 0.06 mg and is equivalent to 40 kg pig muscle, 46 kg cattle muscle, 2 kg pig liver, 1 kg cattle liver, 0.4 kg pig kidney and 0.2 kg cattle kidney. The validity of the methods was tested four times a year using spiked check samples.
