The objectives of this study were to investigate the impact of heavy metals in two freshwater decapods and to evaluate the toxicity and human health risks through the consumption of these freshwater decapods. Nine (9) heavy metals were investigated in accordance with standard procedures and analyzed monthly from March 2015-August 2016 in the studied decapods. The results of the heavy metal concentrations in the prawn and crab varied in this rank; Fe > Zn > Mn > Cu > Pb > Cd > Cr > Ni = V for prawn and Zn > Fe > Mn > Cu > Pb > Cd > Cr > Ni = V for shrimp. The results of the human health risk assessments revealed high values of Iron (Fe) and Zinc (Zn) for the target hazard quotient (THQ) and estimated daily intake (EDI) as well as high values of Iron (Fe), Zinc (Zn), and Manganese (Mn) for the health risk impact (HRI). All most all the values obtained were above allowable limits in prawn and crab respectively. Strict environmental laws should be reinforced and compliance should be adhered to in order to protect humans from consuming freshwater decapods sourced from various points.

Several nations of the world have issued instructions such as travel restrictions, border closure, and lockdown, plus other directives proposing that non-essential care must be withdrawn including assisted reproductive services, in an attempt to identify resources to ascertain the dissemination of SARS-CoV-2. This has led to massive shortage in medical supplies, inappropriate service delivery, hike in price, decrease in staff work load, salary cut, decrease in the utilization of qualitative maternal, and reproductive health-care services thereby creating high risk on reproductive health and global bioeconomy. The search for right candidate for the management of coronavirus disease 2019 and several reproductive health challenges begins with the screening of natural products to identify novel active constituent. Moreover, there is need to pay more attention to crucial phytochemical, bioactive fractions, phytoanalysis, and phytopharmacological investigation for effective drug discovery most especially these bioresources from beneficial microorganisms, plants, and ocean deposits that could help in mitigation of SARS-CoV-2 and reproduction health challenges through chemoinformatics, informatics, synthetic biology, nanotechnology, and metabolomics hence boosting the global economy.
