Hambidge KM, Chavez MN, Brown RM, & Walravens PA (1979) Zinc nutritional status of young middle-income children and effects of consuming zinc-fortified breakfast cereals. Permanent high exposure to zinc gives rise to the selection of zinc-tolerant genotypes, e.g., Lemna minor (Van Steveninck et al., 1990) which detoxifies zinc as zinc phytate in vacuoles, and in several algal species (Say et al., 1977; Harding & Whitton, 1981). There were no differences in zinc content of the spiders fed on woodlice from their own site, and those spiders starved throughout the experiment. When seven pregnant women with low serum zinc levels (< 11.5 µmol/litre) were given a zinc supplement of 90 mg/day for the last 1325 weeks of pregnancy, no adverse effects were associated with the supplementation (Jameson, 1976). There were no control groups in this study and the copper status of the subjects was not measured.

These approaches need to be further developed and validated against bioassays. Si par contre le pH est supérieur à 8,0, il peut y avoir précipitation du zinc. Hobson & Birge (1989) found that tolerance to zinc in 96-h acute toxicity tests increased significantly after 14 days of exposure to zinc at 0.6 mg/litre but decreased significantly following exposure to 1.8 mg/litre for 7 and 14 days. Maternal zinc deprivation of rhesus monkeys throughout most of the third trimester (Sandstead et al., 1978) and throughout gestation and lactation (Golub et al., 1985) caused acrodermatitis in the dam and subsequent reduction of exploration and play in infants during weaning.

Systemic depletion of this element therefore inevitably leads to deleterious effects. London, Kluwer Academic Publishers, pp 167181. The amount of zinc ingested was estimated to be approximately 325650 mg. Lethargy, along with drowsiness, unsteady gait, and increased serum lipase and amylase levels, was seen in an individual who had ingested 12 g of elemental zinc, equivalent to 150 mg/kg body weight, resulting in increases in blood zinc concentrations (Murphy, 1970).

Positive correlations between hair zinc concentrations and serum zinc are only observed in chronic, severe zinc deficiency in the absence of confounding factors. Harrison (1979) analysed dust samples collected in Lancaster, United Kingdom, for their metal content. La exposición de voluntarios a concentraciones de zinc de 77- 150 mg/m3 durante 15- 30 minutos dio lugar a un aumento de los síntomas en algunos de ellos, una acusada respuesta inflamatoria relacionada con la dosis, con aumento de los linfocitos polinucleares en el fluido de lavado bronquioalveolar, y un aumento acentuado de la citoquinesis.

Brit J Nutr, 68: 515527. Zinc uptake is governed not only by the zinc concentration in the water but also by evapotranspiration, which is not taken into account in most experiments with duckweed (Lemna minor) (Hutchinson & Czyrska, 1975; Brown & Rattigan, 1979; Dirilgen & Inel, 1994). Ces troubles sont généralement réversibles et cèdent à une supplémentation zincique. Zinc accumulated in the organic horizon (organic matter layer) of sandy soil, with low concentrations in the mineral horizons (mineral layers) (Pedroli et al., 1990). Las concentraciones altas de zinc en los alimentos (2000 mg/kg) se asociaron también con un aumento de las resorciones y de los casos de muerte prenatal en ratones y ratas; este resultado también se ha observado en ovejas y hámsteres.

En faisant appel à des indices physiologiques fonctionnels comme la croissance, le sens du goût et l'adaptation à l'obscurité et en les complétant par une épreuve biochimique (par exemple, le dosage du zinc dans le plasma ou les cheveux) on perçoit mieux les conséquences fonctionnelles de la carence que l'on s'efforce de déterminer. An evaluation of zinc must therefore take into account the adverse effects of low zinc concentrations as well as those attributed to excess zinc. Table 19. Low temperatures and light intensities restrict root development and therefore zinc uptake. In: Batley, GE ed.Trace element speciation: analytical methods and problems. Woodlice fed diets containing up to 20 000 mg/kg for 8 weeks showed decreased survival at concentrations of > 5000 mg/kg (Beyer et al., 1984). Important data gaps have been identified including, in particular, chronic marine toxicity data and toxicity data for terrestrial plants. Marine Freshwater Res, 49: 203214. Until recently, a period of 6 months has been said to be the minimum interval for the provision of reliable growth data. (1994a) calculated the 48-h EC50, based on filtration rate, to be 1.35 mg/litre for the zebra mussel (Dreissena polymorpha). En estudios sobre el terreno se han detectado efectos adversos en los invertebrados acuáticos, los peces y las plantas terrestres en las cercanías de fuentes de contaminación por zinc.

A cross-sectional analysis, conducted on spirometric lung-function parameters in zinc welders, non-welders with exposure to welding fumes and control subjects (Marquart et al., 1989), revealed no differences in lung function between groups, and changes in lung function over five consecutive work shifts were not related to the exposure level. Conversely, the intake of high zinc levels (140 mg/day) reduced calcium absorption in men with low calcium intakes (200 mg/day) but calcium absorption was not affected when calcium intake was 800 mg/day (Spencer et al., 1987).

Greger JL, Zaikis SC, Abernathy RP, Bennett OA, & Huffman J (1978c) Zinc, nitrogen, copper, iron, and manganese balance in adolescent females fed two levels of zinc. Reversible clinical signs and radiological effects, including aches and pains, dyspnoea, dry cough, lethargy, neutrophil leukocytosis, pyrexia, and widespread abnormality of both lung fields, with multiple nodules measuring 34 mm and becoming confluent and ill-defined in some areas, were seen when an individual was exposed to zinc fumes in a shipyard over a 3-week period (Brown, 1988). Zinc caused reductions in pancreas and gonad weight in relation to body weight. It was concluded that the distribution pattern remains more or less the same whether zinc is added during or after digestion.

In particular, biological effects at various ratios of zinc and copper require further investigation. Samples from Greenland snows analysed for their heavy metal contents showed a decrease in anthropogenic zinc by a factor of about 2.5 during the period 19671989, which is stated to be a consequence of the abatement policies for industrial emissions in the European Union and North America (Boutron et al., 1991). Entre los efectos agudos en roedores tras la inhalación o la instilación intratraqueal de compuestos de zinc figuran trastornos respiratorios, edema pulmonar e infiltración de leucocitos en los pulmones. Zinc deficiency appears to be a major contributing factor in this syndrome. Straube & Walden (1981) reported that 20 of 25 ferrets (Mustela putorius furo) being used in an experiment died of renal failure after eating raw meat that was accidentally contaminated with zinc from the wire cages.

For water hardness of > 100 mg/litre, CaCO3, all NOECs are > 500 mg/litre, except in one behavioural study (Korver & Sprague, 1989), which reported a NOEC of 60 mg/litre. Br J Nutr, 70: 221234. Total zinc concentrations of 17.1 µg/litre significantly reduced chlorophyll a, primary productivity, dissolved oxygen, specific zooplankton populations and zooplankton species diversity. Can J Bot, 56: 17441749. Environ Res, 49: 4049. Another approach is to increase the zinc efficiency of cultivated plant species (El Bassam et al., 1990). Research trends in the field of environmental analysis. After 21 days of pre-exposure to 0.6 or 1.8 mg/litre there was no significant effect on acute toxicity compared with controls. Effects of phytate and alpha-cellulose. The Kd value was strongly related to pH, although the presence of extractable manganese oxides and hydroxides and the magnitude of the anion exchange capacity were also important.
