The study was done to assess the regeneration status of lowland bamboo after gregarious flowering and death in BenishangulGumuz Region, Homosha District, Jimma and Sherkole Kebeles, North west of Ethiopia. A systematic sampling technique was used to survey lowland bamboo. Twenty and eleven sample plots were surveyed in Jima and Sherkole Kebeles respectively and each plots with 10 x 10 m size. Field observation, regeneration inventory, FGDs, and questionnaire survey on 80 households were used to collect data. Descriptive age class across different management. and inferential statistics were used for data analysis. The seedlings and culms had a significant difference (One-Way ANOVA p <0.05) in density, size (DBH) and height between the two sites. However, the size difference was statistically insignificant. Height and diameter classes distribution indicated highest number of individuals in the lower classes

Environmental toxicology is a relatively young field of science concerned with the study of environmental pollutants in air, dust, sediment, soil, and water in the environment and their effects. Since the 1970s, scientists concerned with toxins in the environment focused their research on the impacts of various chemical agents on ecosystems and health hazards associated with certain chemicals including asbestos. Asbestos, the foremost among toxic fugitive dust, resulting from exposure. has the ability to resist heat, fire, and electricity. Asbestos is a group of naturally occurring fibrous silicate materials with known toxicity Although the precise mechanisms by which asbestos fibers cause toxic injury have not yet been fully determined, it is well-documented that fibers that persist within the lung or the mesothelium are capable of producing fibrogenic and tumorigenic effects in these tissues.
