  <dc:description>&lt;div class="abstract-group "&gt;&lt;div class="article-section__content en main"&gt;&lt;p&gt;Blood collected from song sparrows (&lt;i&gt;Melospiza melodia&lt;/i&gt;) and American robins (&lt;i&gt;Turdus migratorius&lt;/i&gt;) captured with mist nets in a lead-contaminated (assessment) area and nearby uncontaminated (reference) areas within the Coeur d'Alene Basin in northern Idaho was analyzed for δ-aminolevulinic acid dehydratase activity (ALAD) and hematocrit levels, and livers were analyzed for lead. Mean ALAD inhibition in the assessment area was 51% in song sparrows and 75% in American robins. The proportion of the sampled population with ALAD inhibition &amp;gt;50% was calculated to be 43% for song sparrows and 83% for American robins. Assessment area hematocrit values for song sparrows (&lt;i&gt;&lt;span&gt;x&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;= 39.9) and American robins (&lt;i&gt;&lt;span&gt;x&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;= 39.5) were lower than in reference areas (&lt;i&gt;&lt;span&gt;x&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;= 42.4 for song sparrows and 40.2 for American robins); however, differences were not statistically significant (&lt;i&gt;p&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&amp;gt; 0.05). Significantly higher levels of lead (wet weight) were found in livers from song sparrows captured on the assessment area (&lt;i&gt;&lt;span&gt;x&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;= 1.93 ppm) than on reference areas (&lt;i&gt;&lt;span&gt;x&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;= 0.10 ppm) (&lt;i&gt;p&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;= 0.0079). Study results indicate that 43% (95% confidence interval [CI] = 12.9-77.5%) of the song sparrows and 83% (95% CI = 41.8-99.2%) of the American robins inhabiting the floodplain along the Coeur d'Alene River in the assessment area are being exposed to lead at levels sufficient to inhibit ALAD by &amp;gt; 50%. Variability in lead exposure indicators was attributed to high variability in environmental lead concentrations in the Coeur d'Alene River Basin.&lt;span id="references-section-1" class="section__title"&gt;&lt;/span&gt;&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
