ABSTRACTMicroplastics (MPs) in natural water resources and their inclusion in food webs has become a critical issueglobally. The paucity of risk assessment data on the levels of MPs in Ikpoba River, Benin City, Nigeria, warrantedthis research which was done via Fourier Transform Infrared (FTIR) Spectroscopy.

The assertion that the level instrument is the best instrument for determining elevations of points needs to be reviewed; this is because technological advancement is making the total station a very reliable tool for determining reduced levels of points. In order to achieve the objective of this research, reduced levels of stations were determined by a spirit level and a total station instrument.

We recently proposed a method to establish an optimal ionospheric shell height model based on the international GNSS service (IGS) station data and the differential code bias (DCB) provided by the Center for Orbit Determination in Europe (CODE) during the time from 2003 to 2013. This method is very promising for DCB and accurate total electron content (TEC) estimation by comparing to the traditional fixed shell height method. However, this method is basically feasible only for IGS stations. In this study, we investigate how to apply the optimal ionospheric shell height derived from I
