A., Environmental Effects of Sand and Gravel Mining on Land and Soil in Luku, Minna, Niger State, North Central Nigeria. Journal of Geosciences and Geomatics, vol. 2, no. 2 (2014): 4249. doi: /jgg221. 1. Introduction . Sand and gravel mining refers to the process of removing sand or gravel from a place of its occurrence [1].
Environmental Effects of Sand and Gravel Mining on Land . The increase in the demand for sand and gravel for construction and other purposes such as flood control has placed immense pressure on the environment where sand and gravel resources occur This study was carried out to determine the environmental effects of sand and gravel mining in Luku North central Nigeria using field
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have
pollution are the environmental effects that result due to sand and gravel mining in the area. Result of the chemical analysis shows that average concentrations of Pb, As, Cu, Ni, Cd, Hg, Ag and Zr are,,,,,, and respectively. These concentrations
and gravel are being extracted from the active channels and million ty1 of sand from the river oodplains. The quantity of instream mining is about 40 times the higher than the sand input estimated in the gauging stations. As a result of indiscriminate sand mining, the riverbed in the storage zone is getting lowered at a rate of 7
#0183;#32;Depending on the type and amount of mining, the physical effects of instream gravel mining may include improved flood control and channel stability in rapidly aggrading rivers. Instream mining also results in the destruction of aquatic and riparian habitat through large changes in channel morphology (Sandecki, 1989).

An extensive gravel mining industry operates in the San Gabriel Valley. Gravel mining in the area has been in existence for more than 100 years and has supplied the sand and gravel that has built over 70% of the roads in California. Most of the mining operations are located in Irwindale, which has 17 gravel pits. Seven of these are active quarries.

Instream gravel mining commonly causes incision of the channel bed, which can propagate upstream and downstream for kilometers. As a result, bridges and other structures may be undermined, spawning gravels lost and alluvial water tables lowered.
The increase in the demand for sand and gravel for construction and other purposes such as flood control has placed immense pressure on the environment where sand and gravel resources occur. This study was carried out to determine the environmental effects of sand and gravel mining in Luku, North central Nigeria, using field observations and laboratory analysis of soil samples.
