Although lead-containing paint was banned for residential use in the United States in 1978, residual paint on older buildings is the most frequent source of lead exposure in young children. But, a variety of other substances contribute to lead poisoning. Paints used in industry or on equipment or in playgrounds or parks may still contain lead. Tap water can be contaminated by lead pipes, copper pipes with lead solder or bronze and brass faucets containing lead. Automobile exhaust from leaded gasoline, factory emissions and pesticides contribute to both air and soil lead pollution.
Lead exposure can also result from lead crystal and poorly glazed ceramic dishware.
Ceramic dishware produced outside the United States, china and lead crystal can leach dangerous amounts of lead into food. Food can also be contaminated with lead when it is grown in soil with a high lead content or when plants are sprayed with insecticides containing lead. Nutrition Proper nutrition is important in the prevention of lead poisoning, especially in young children. A balanced diet of grains, fruits, vegetables, dairy products and selections from meat, poultry, fish, dry beans, nuts or eggs can help decrease susceptibility to lead intoxication. It is particularly important to include adequate amounts of calcium and iron.
