[Cadmium content of vegetable foods in the effective range of a lead smelting plant].

In the effective range of a lead smelting plant, the repercussions of cadmium emissions (mainly past) on vegetables, fruit, soil and drinking water as well as of immissions were investigated by means of atomic absorption spectrometry. As compared to the "normal" cadmium level, the cadmium contents in vegetables and fruit were some 2- to 85-fold higher; and those in soils, some 70- to 230-fold. The mean contents in vegetables ranged from 0.4 to 25.5 p.p.m. (on a dry-weight basis); those in fruit, from 0.09 to 1.17 p.p.m. Cadmium concentrations varying from 6.8 to 22.8 p.p.m. were found in soil samples. The drinking water contained 0.009 p.p.m. of cadmium. The mean cadmium contents in the atmosphere and the sedimentary dust were 0.007 mg/m3 and 0.550 mg/m2/30d, respectively. In the territory investigated, the total human uptake of cadmium supplied by vegetables, fruit, potatoes, drinking water and air is 3.3-32.6 microgram/d. The following cadmium levels were found in human organ samples obtained at necropsy: right and left renal cortex, 33.99 and 35.98 p.p.m., respectively; liver, 3.14 p.p.m.; lungs, 0.63 p.p.m.; pancreas, 1.47 p.p.m.; brain stem, 0.16 p.p.m.

[Bone fluorosis without occupational exposure in chronic renal insufficiency].

Report on a 70-year-old male with bone fluorosis which was ascertained radiologically, by section and fluor analysis in the bone ash. With empty professional anamnesis as cause was found the presence of a chronic renal insufficiency with simultaneously increased fluor content of drinking water. The decreased renal excretion of fluoride might have led to the pathological development in the bones. It is referred to the significance of extra-medical fluor load and the knowledge of the renal function when halogen is therapeutically used.

[Evaluation of the cadmium content in sedimented and floating dust as factors in contamination of the biosphere].

In a territory being 3.500 km2, the cadmium deposits from the atmosphere were determined at 63 sites in 52 towns and communities. These determinations yielded a mean value ranging from 0.13 to 0.15 mg/m2 . 30 d. On the contrary, the mean value (-x) was 0.33 mg/m2. 30 d in the region of heavy-metal-emitting industries. The mean cadmium content in the aerosol was between 0.003 and 0.004 microgram m-3 and, respectively, 0.016 microgram m-3 in case of cadmium emission. It was calculated that the mean proportion of cadmium in the sedimentary dust was between 13 and 16 p.p.m. The cadmium burden, as estimated as cadmium sediment, correlated with the extent of the developmental area. The authors recommend for the present the following maximum permissible values: 0.05 microgram m-3 in the aerosol, and 0.15 mg/m2. 30 d. The cadmium content in the sedimentary dust may be considered to be a permanent burden applied via the food chain, whereas the content in the aerosol is of less importance to the total uptake in man. The calculation of the daily pulmonary uptake yielded a value of 0.075 microgram, from which an absorption of 0.038 microgram is estimated.

[Evaluation of the arsenic content of the air].

Determinations of the arsenic contents in subjects, aged 10-11 years, from an arsenic-exposed region yielded the following arithmetic means: hair, 5.5 p.p.m. (S.D. = +/- 4.2); urine, 0.011 p.p.m. (S.D. = +/- 0.010). In children from a non-exposed region the authors found; hair, 0.5 p.p.m. (S.D. = +/- 0.4); urine, 0.004 p.p.m. (S.D. = +/- 0.005). The average arsenic concentrations in the exposed region were 19 mg/m2-30 d (sedimentation dust) and 0.9 microgram/m3 (aerosol); the corresponding values for the control region were 0.029 mg/m2-30 d and 0.0 microgram/m3, respectively. The two groups of subjects had general clinical examinations. There was a significant difference between the two groups in total morbidity, whereas the morbidity structure was similar. This result cannot be brought in causal relation to the differences in arsenic contents; it is possible that other influences play a rôle in the region under investigation.

[The contamination of vegetable foods by lead containing street dust].

To assess the contamination of fruit and vegetables by lead-containing road dust, products displayed in the open air and in retail shops, respectively, were analysed for lead content. The lead exposure within the range of the retail shop was characterized by an aerosol with 0.2-2.5 microgram/m3 and a sedimentable lead dust of 2.13-6.55 mg/m2-30 d. The lead content of the products displayed in the open air was some 0.5 to 6-fold higher. This difference was statistically significant. 92-100% of the lead dust could be removed from the products by washing with water. Increased lead contents were also found on fruit stored in a cellar (0.66 and 0.42 p.p.m., respectively) near a parking place. In consideration of the proportion of these foods in the diet consumed, no health hazard to the population can be deduced from these data; but in single cases, a temporary rise of the blood-lead level may occur. Covering fruit and vegetables presented in the open air with thin-sheet plastics or selling such products in plastics bags will prevent contamination.

[Lead content of vegetable foods in vicinity of lead emitting industry].

By means of atomic absorption spectrophotometry, the authors determined the lead content in vegetable, fruit and soil samples from the environments of a lead-smelting plant. The lead values obtained were some 10- to 100-fold higher than those found normally. The mean lead content in vegetables varied from 2 to 150 p.p.m. in dry matter; that in fruits, from 4 to 35 p.p.m. Lead concentrations ranging from 575 to 2900 p.p.m. were detected in the soil samples. The mean lead content in the atmosphere was between 0.62 and 0.95 mug/m3 (maximum value 12 mug/m3). From these data it was calculated that the total resorption of lead from vegetables, fruits, potatoes and air varied from 0.04 to 0.49 mg/day in the territory under investigation. To protect the population against increased intake of lead, it is recommended to abandon individual and commercial vegetable and fruit growing, especially leaf vegetables. Since the contamination of the soil persists for generations, the authors discuss its replacement by non-contaminated surface soil.
