Preparations containing both organophosphates and pyrethroids are commonly used in insect control. Toxicokinetic interactions between α-Cypermethrin (CM ) and Chlorpyrifos (CPF) were studied in rats. The animals were given a solution of CM or CPF in rapeseed oil at a dose of 10 mg/kg and a mixture of CM and CPF at a dose of 5 mg/kg each by an intragastric tube once a day for 28 days. The concentrations...
In the current study the influence of single compounds and concurrent exposure to popular insecticides: organophosphate (OP) – chlorpyrifos (CPF) and synthetic pyrethroid (PYR ) – α-cypermethrin (CM) on some oxidative stress parameters and cholinesterase (ChE) activity in rats was investigated. Animals received by gavage 10 mg of single compounds or 5 mg of each per kg bw daily in rapeseed oil for...
The aim of this study was (a) to determine the concentration of fluoride and cadmium in urine of 1240 children ( 635 boys, 605 girls) from Gdańsk, aged 7-14; and (b) to examine whether a correlation exists between age and sex of children, the location of the schools, and the urinary levels of fluoride and cadmium. Fluoride was determined potentiometrically using a fluoride-specific electrode. Cadmium...

The aim of this study was: (a) to estimate the concentration of selenium in plasma of 136 residents (59 men and 77 women) of the Gdansk region, northern Poland, aged 19-70; and (b) to compare the obtained results with data corresponding to healtly populations living in different European countries. Selenium in plasma was determined by atomic absorption spectrometry using the hydride generation method...
The fluoride content in drinking water and hen ankle bones of 48 localities in northern and central Poland was determined. The mean fluoride concentration in water was 0.1 - 0.4 mg/1, in bones 0.4 - 0.6 mg/g. An insignificat correlation between the fluoride content in hen bones and drinking water was found in this study. Hen bones are not well suited for use as a bioindicator for assessment of environmental...
