Syracuse, New York has been fighting an uphill battle against lead. It’s in their homes, soil, and water and disproportionately affects lower-income communities. Children are especially sensitive before the age of 6, experiencing decreased cognitive function, reduced motor control, developmental disabilities, and death, among others. 12 percent of children in Syracuse tested positive for elevated blood lead levels, four times the national average. Diet can help combat lead contamination by increasing iron levels. Iron and lead bind to the same transport protein in the small intestine where metals are absorbed into the bloodstream. With only 77 grocery stores to cover 25.5 square miles and over 140,000 people, Syracuse’s residents may rely on convenience stores, dollar stores, and fast-food restaurants to pick up the slack. Combating food insecurity may be possible by targeting food deserts and increasing access to healthy foods. To find the areas where small-scale retail would benefit the most, a Boolean Suitability Analysis was used to find food deserts using poverty levels, minority status, population density, existing grocery stores, and vacant lot parcel data. A Weighted Linear Combination Suitability Analysis found locations that ranked higher for the intersection of food deserts, childhood elevated blood lead levels, current lead violations, and tracts with high numbers of children under 5-years-old. Of the 165 locations from the resulting analysis, 65 locations ranked between medium and high suitability. This analysis will help local officials, community leaders, and non-profit organizations determine where to combat food deserts and elevated blood lead levels in children.
