Assessment of exposure to toxic metals and measures to address deficiency of essential trace elements in young children in rural Hubei, China

Children are exposed to toxic metals via diet and environment, which results in adverse health effects. Several trace elements are important for the nutritional status of children; however, little information is available for rural regions in Asia. Our goal was to assess the body burden of lead, cad...

Zusammenfassung:Children are exposed to toxic metals via diet and environment, which results in adverse health effects. Several trace elements are important for the nutritional status of children; however, little information is available for rural regions in Asia. Our goal was to assess the body burden of lead, cadmium, and aluminum (Al) as toxic metals and calcium (Ca), zinc, copper, selenium (Se), strontium, and boron as trace elements in children. Multiple environmental samples, including soil, dust, fine particulates, drinking water, and food, were collected for each family. A survey was conducted by trained personnel to record detailed information about children attending a rural school. Twenty-four-hour urine samples were collected. The levels of toxic and essential trace elements were determined by inductively coupled plasma mass spectrometry. We found that the daily intake of toxic metals was below the recommended maximum, suggesting low health risks. More attention should be given to the ingestion of Al by the hand-to-mouth pathway. Ca deficiency was discovered to be a serious health problem for rural children, with Ca inadequacies reaching 96%. The excessive intake of Se-rich products from industry suggests an increased risk of toxicity. This study highlights the health risks to children who live in rural regions and the importance of dietary Ca supplementation in school meals.
