Single-crystalline ZnS0.6Se0.4 was synthesized by thermal evaporation without a metallic catalyst. The as-prepared ZnS0.6Se0.4 nanowires with a rough surface and a larger diameter were in contrast to the as-prepared ZnS nanowires. The growth mechanism for ZnS0.6Se0.4ZnS nanowires appears to be reasonably explained by the vapor–solid growth mechanism involved in ZnS nanowires, which serve as in-situ source templates. The cathodoluminescence properties of ZnS0.6Se0.4 reveal a broad emission band. The emission band of ZnS0.6Se0.4 nanowires exhibits a redshift in comparison with that of ZnS nanowires.

“…Riverine sediments investigation is a widely used technique for environmental quality assessment, since the riverine sediments accumulate organic and inorganic pollutants [1][2][3][4] over time causing direct or indirect effects on the overlying water system as well as on human beings, hence, valuation of heavy metals in the riverine sediments is indispensable [5]. Riverine sediment at the bottom of a river plays a significant role in the pollution scheme of such river system as they could act as a 'sink' or 'source' of heavy metals [6][7][8].…”

Ecological Risk Assessments are executed to appraise the probability of adverse ecological effects occurring as a consequence of exposure to biological, physical, or chemical factors that causes hostile responses in the environment. Several studies have shown extensive heavy metals and crude oil contamination of soils, sediments, rivers, creeks, and ground waters in Ogoniland, Nigeria. However, the Sogho Community in Ogoniland has not been studied. Hence, this paper evaluates the distribution and ecological risk assessment of heavy metals in riverine sediments of Maa-Dee-Tai River in Sogho Community, Ogoniland, Rivers State, Nigeria using Solaar Thermo Elemental Atomic Absorption Spectrophotometer, Model SN-SG 710960 after total dissolution of riverine sediments by hydrofluoric acid (HF) and aqua regia (HNO 3 : HCl; 1:3, v/v) at a temperature of 100 o C. Distribution of heavy metals in the sampling stations reveal that Werri had the maximum magnitude of nickel (Ni) among the three stations assessed and the mean value for the three stations is 4.21±0.92mg/Kg. The average values recorded for Ni in the three stations were; 3.52±0.58, 4.04±1.04 and 5.07±1.14mg/Kg for Dee-Tai, Barawansah and Werri respectively. The average mean concentration of the sampling stations for each metal (mg/kg) are Ni (4.21), Zn (3.56) Cr (3.35), Pb (3.25), Cu (1.59), Co (0.8), As (0.12) and Cd (0.12). The order of abundance of the metals in the riverine sediments is Ni>Zn>Cr>Pb>Cu>Co>As>Cd. In all the stations examined, Nickel (Ni) was the most abundant metal. The pollution indices revealed that the river was unpolluted with the different heavy metals studied. The potential environmental risks assessment of heavy metals in riverine sediments of the Maa-Dee-Tai River in Sogho Community, Ogoniland reveals that the river poses low risks in terms of pollutants with reference to heavy metals in the sediment. Hence, it is necessary to preserve the natural state of the river.
