Microplastics Pollution Assessment in the Surface Water and Sediment of River Niger, Lokoja, Nigeria

Pollution from microplastics (MP) is now considered to be a major global environmental concern, and Nigeria is not an exception. In Nigeria, the River Niger is an essential resource that is used for agriculture, transportation, and fishing. The purpose of this study was to evaluate MPs contamination in Nigeria's Niger River, Lokoja, Kogi State: The sampling was carried out in 2024 between March and June. Following digestion with 10% KOH, density flotation with NaCl, and filtration, the water and sediment were examined.

Testes Histo-Morphological Changes in Laboratory Rats, Rattus norvegicus, Exposed to Various Spectral of Artificial Light at Night (ALAN)

Exposure to various spectral of light at night is presently inevitable, hence the need to examine its spectral effect on male reproductive function. This study aimed at evaluating the periodical change in testicular histomorphology of albino rats exposed to various lights spectral {Blue (BL), Green (GL), Yellow (YL), Red (RL), and White (WL)} at night for 126 days. Compact fluorescence bulbs, 11 watts, maintained at 300 Lux, were used.
