从8918名农民中，选择了237名当地生产的食品消费量很高的农民。受试者的水源是私人威尔斯井，酸度不同。pH值之间的显著相关性（中位数6.7，范围4.7-8.6），铝与元素浓度呈负相关（铝;中位数0.07 mumol/l），镉（Cd; 0.44 nmol/l）、铜（Cu; 0.24 mumol/l）和铅（Pb; 1.9 nmol/l），钙（Ca; 0.62 mmol/l）和镁（Mg; 0.21 mmol/l）阳性。铝浓度与水体pH值或元素浓度之间没有相关性（0.17 μ mol/l），镁（0.86 mmol/l）和硒（Se; 1.0 mumol/l）血浆中，Cd（2.0 nmol/l）、铅（0.19 mumol/l）和汞（Hg; 13 nmol/l），或尿中的铝（12 mumol/mol肌酐）和铜（11 mumol/mol肌酐）。血汞、血硒浓度与鱼类摄入量有关，血镉、铅与吸烟有关，尿铝与抗酸剂摄入量有关，血铅与步枪活动和狩猎有关，血汞与狩猎有关。酸沉降对饮用水中的元素浓度有影响，但对这些元素在被调查对象中的保留没有影响。
From a population of 8918 farmers, 237 were selected whose consumption of locally produced foods was high. The subjects' water sources, private wells, were of different degrees of acidity. Significant associations between pH (median 6.7, range 4.7-8.6) of the drinking water and element concentrations were found. The correlation was negative for aluminium (Al; median 0.07 mumol/l), cadmium (Cd; 0.44 nmol/l), copper (Cu; 0.24 mumol/l) and lead (Pb; 1.9 nmol/l), and positive for calcium (Ca; 0.62 mmol/l) and magnesium (Mg; 0.21 mmol/l). Associations could not be found between the pH of, or element concentrations in, the water and concentrations of Al (0.17 mumol/l), Mg (0.86 mmol/l) and selenium (Se; 1.0 mumol/l) in plasma, Cd (2.0 nmol/l), Pb (0.19 mumol/l) and mercury (Hg; 13 nmol/l) in blood, or Al (12 mumol/mol creatinine) and Cu (11 mumol/mol creatinine) in urine. The concentrations of Hg in blood and Se in plasma were related to fish consumption, Cd and Pb in blood to smoking, Al in urine to antacid intake, Pb in blood to rifle activities and hunting, and Hg in blood to hunting. Acid precipitation has an effect on element concentrations in drinking water, but not on the retention of those elements in the subjects investigated.
