Distribution of Lead and Cadmium in Soils on Koko Seaport, Delta State, Nigeria

Soil contamination by Lead and Cadmium is a prevalent ecological problem that requires attention because these two metals are toxic and could accumulate and translocate in soil over time, which poses a risk of entering the food chain and affecting the living organisms in the food web. The objective of this study is to evaluate the levels of Pb and Cd in soil from selected sampling locations of the Koko Seaport in Delta State, Nigeria. Five areas near Koko Seaport were investigated for the transport of these heavy metals in the soil. Statistical analysis using ANOVA and chart models was used to determine the concentration of these metals. Cadmium and lead levels that were significant were found in the studied areas. The data did not show any differences between the two metals due to the significance of the *p>0.05 value. The variations showed a surge in comparisons of the amounts of cadmium in stations 2 and 3, respectively, as well as significant values for cadmium compared to lead. The outcome was directly influenced by the type and quantity of hazardous wastes present in the research area. The recommended remedial actions for these metals include soil cleansing, immobilization, and the choice of plants with hyper bio accumulation for phytoremediation methods that allow the use of genetic engineering

Impact of the COVID-19 pandemic on adolescents’ sexual and reproductive health in low- and middle-income countries

Adolescents living in low- and middle-income countries (LMICs) are struggling with accessing sexual and reproductive health (SRH) services, and COVID-19 has escalated the problem. The purpose of this review was to identify and assess the existing literature on the impact of the pandemic on SRH needs and access to services by adolescents in LMICs. A scoping review was conducted to collate findings on the topic. Searches were performed on eight databases. Data were extracted and categorized into various themes. After removing duplicates and performing a full-text reading of all articles, nine articles were included in our review. Our findings generated several themes related to adolescents’ sexual and reproductive health during the COVID-19 pandemic. These include (1) limited access to sexual and reproductive health services, (2) school closure and increased rate of early marriages, (3) sexual or intimate partner violence during COVID-19, (4) disruption in maternity care, (5) adolescents’ involvement in risky or exploitative work, (6) intervention to improve sexual and reproductive health services during COVID-19, and (7) policy development related to adolescent sexual and reproductive health. Several recommendations were made on policies—for instance, the use of telemedicine and community-based programs as a way to deliver SRH services to adolescents during and after a pandemic
