Paternal Biomass Smoke Exposure in Rats Produces Behavioral and Cognitive Alterations in the Offspring.

Particular concern at the present stage is the health effects of wildfires' smoke. The aim of the study was to determine the impact of paternal biomass-smoke exposure on offspring's behavior and cognitive abilities. Male rats were exposed to biomass smoke for four hours/day, five days/week, for four weeks.

Dynamics of Excretion of Thiodiacetic Acid into Urine in Polyvinyl Chloride Production Workers.

Background: Thiodiacetic acid (TDAA) is the main metabolite of vinyl chloride (VC) and 1,2-dichloroethane (EDC) and its urinary level is correlated with the level of exposure to these chemicals.

Objective: To study dynamics of the excretion of TDAA into urine of polyvinyl chloride (PVC) production workers.

Methods: The study sample consisted of 65 workers of VC and PVC divisions with various time intervals following exposure to the chemicals, 10 shift workers from PVC division, and 34 workers not exposed to the chemicals (control group).
