REPORTS/ All eight members of a rural Wisconsin family experienced a three-year period of sensory hyperesthesias, muscle cramps, recurrent pruitic conjunctivitis, earaches, and otis media, sinusitus, bronchitis, pneumonia, nose bleeds, easy bruising, and seasonal alopecia ranging from thinning hair to complete baldness. A four-week old neonate with recurring viral pneumonia and respiratory exacerbations was treated with a permanent tracheotomy. All children exhibited recurrent "measle-like" rashes. The children who went barefoot experienced reddened, thickened skin on the soles of the feet and babies who crawled on the floor showed rashes on the legs, arms, and diaper and stomach area which later became desquamated. The youngest child developed a thrombosed penile artery. All family members experienced malaise, easy fatigue, and lack of sensation in the arms, hands, feet, and legs. Severe muscle cramps were reported in the evening hours. Frequent headaches developed and the two parents reported "black-outs" sometimes lasting for two hours in duration. The two youngest children had multiple grand mal seizures from birth to one year of age. One child was diagnosed by a physician as having idiopathic thrombocytopenic purpura. The mother\s fifth pregnancy resulted in a premature birth with placenta previa or abruptio placenta. It was determined that the cause of the disorders was due to the use of CCA-treated marine wood and plywood scraps in a wood stove used inside the home for heating in winter months. Reported exposure occurred through ingestion, inhalation, and direct contact with ashes, vapors, and unburned wood.

REVIEWED** BIOMONITORING/ The study investigated whether wood usage by informal food vendors and household residents in Cape Town results in the absorption of arsenic (As), chromium (Cr) and copper (Cu) owing to release of these metals in the burning of chromated copper arsenate (CCA)-treated wood. METHODS: The participants (N=78) selected included an equal number of food vendors and non-vendors from 2 informal settlements. All participants answered a questionnaire concerning exposure and were tested for urinary Cr, Cu and As, while the urine of 29 participants was also tested for toxic As (As(tox)). RESULTS: Multivariate analysis showed that the time spent in close proximity to the wood, as well as the quantity of wood used for cooking and for household use, was weakly positively associated with urinary levels of As, Cr and the sum of As, Cr and Cu. CONCLUSIONS: The study provides evidence that use of wood likely to contain CCA as a fuel for informal food outlets and household purposes may increase the absorption of inorganic As, Cu and Cr.
