Abstract:
We herein report a 24-year-old male construction worker with occupational lead poisoning who presented with acute abdomen and normocytic anemia. The levels of urinary delta-aminolevulinic acid and free erythrocyte protoporphyrin were elevated without any increase in the level of urine porphobilinogen. Detection of an elevated blood lead level of 100 μg/dL confirmed a diagnosis of lead poisoning. Chelation therapy with calcium disodium ethylenediaminetetraacetate resulted in prompt improvement of the clinical symptoms and the blood lead level. Clinicians should be aware that lead poisoning caused by occupational exposure can still occur sporadically in construction workers in Japan.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
