Abstract: This research examined housing needs in the core area of Akure, Nigeria. This was carried out by identifying the existing housing stock, housing condition and the extent of housing needs in the study area. Six residential neighborhoods were selected from the core area of the city due to their homogeneity characteristics. The study made used of the existing demographic and land use characteristics, primary and secondary data were used for the data collection. A total number of 198 buildings were selected and sampled in the area. Literature was also consulted for proper understanding of the subject matter. The study revealed that, houses in the study area had poor environmental outlook. On housing condition, 50% of the dwellings assessed were either sub-standard or unfit for human habitation. More than 50% of the residential buildings had one or more major defects. Some of the houses were overcrowded and subjected to tenant’s abuse by internal conversion to increase the occupancy rate. The research recommends the need for affordable housing strategy, governmental and institutional intervention to cater for general inadequacies of infrastructures, such as roads, drains, waste disposal and recreational facilities. Stakeholders should collaborate towards enforceable standards for redevelopment and upgrading that could guarantee sustainable development.

Abstract: Leaching of metals (Fe, Mn, Cu, Co, Ni, Zn, Cr, Cd, Pb) and arsenic from mine wastes and their accumulation in waters, soils and sediments have been determined at the former Paukkajanvaara uranium mine in Eastern Finland. A small-scale test mine, operating in 1959-1960, generated 7,300m3 of waste rock and 12,000m3 of mill tailings, which were covered with soil and till in the early 1990s. These two materials, waste rock and mill tailings, were studied as possible sources for metal contamination in surrounding water systems. Water samples from a nearby pond and streams flowing from the site into the pond were collected. In addition, soil, pond sediment and mill tailings samples were taken and metals were leached from them with strong acids. Metal concentrations in the water samples and acid leachates were measured with ICP-MS. Nickel and arsenic concentrations in stream water were seen slightly elevated when compared to natural Finnish waters and metal concentrations in lake sediments show an increasing trend with time, both indicating long term leaching of metals from the waste deposits. All other metal concentration measurements revealed no elevated concentrations. In conclusion, we may state that the site is not a big if any threat to the environment and humans.
