Abstract: The study was conducted at Kano state of Nigeria with data from the National Oceanic Atmospheric Administration (NOAA) using the meteorological station of Mallam Aminu international airport of Kano state. The wind direction of dust transport to Kano state indicated that the majority of the dust events blow from the North-east of Kano state Nigeria, which comes from Lake Chad that has aboundary with Nigeria. The back trajectory also confirmed that most of the dust to Kano comes from the North-east of Nigeria. The dust transportation and mobilisation to Kano state are easy due to the fine nature of the sediments. This harmattan dust mobilisation and deposition are naturally controlled especially by the meteorological factors completely away from the human influence. The effects of these winds are obviously felt in the homes, offices, schools, due to the widespread of the air-borne dust that covers beds, tables, chairs, cars and mostly all available surfaces.
