The rate of solid waste generation has increased to a devastating and uncontrollable rate in ondo state Nigeria. This is as a result of human daily and economic activities. Although, the issue of indiscriminate solid waste disposal is a global issue. Modernization, high standard of living, increase in population, technological innovation and excessive urbanization over the years has drastically contributed to the generation of public waste, through domestic and industrial activities. One of the commonly accepted indicators for assessing the level of development of any nation is the efficient management of its refuse. Inefficient management of refuse poses great threats to public health in any environment. Due to inadequate waste disposal method, dumping of refuse in an unauthorized place is now the order of the day in the country, both in local and national level and penalties that are placed on defaulters are not been effectively carried out. Environment close to dump sites are exposed to significant and rapid environmental degradation mostly in public areas in state which brings about adverse effect on the general sustainability of urban life, poor agricultural yield, widespread of germs and diseases, extinction of aquatic bodies due to water toxicity and acidification. Despite the fact that human health is at great risk, life also becomes unbearable to people living in such environments. The rate of human susceptibility depends on how close the household settlements are to the open areas unlawfully made as dumping sites. When solid wastes are indiscriminately disposed it results to climate change, photochemical reactions, abiotic depletion and extreme weather events like global warming produced by the breakdown of greenhouse gases generated from chemical and radioactive wastes. There are water contamination and water bodies’ blockage, soil and air pollution, communicable and non-communicable diseases in most areas of the state. This paper review the environmental implications arising from indiscriminate disposal of solid waste by residents of ondo state. The paper also identified those risk-factors, such as water pollution, air pollution, flooding, environmental accidents, outbreak of diseases which can lead to health hazards ranging from mild ill-health to severe health calamities. Suggestions were made to help checkmate the risk-factors of indiscriminate disposal of refuse in Ondo state.
