Numerous organic chemicals, either directly manufactured or formed as byproducts of other processes, are released into the environment. Once there, many cause adverse effects on environmental and human systems. Of particular concern are long-lasting impacts from those organic pollutants that remain in the environment for long periods of time. The development of appropriate management strategies to address this problem requires knowledge of the environmental distributions of these pollutants.
Vector-borne diseases have since the 17th century been the leading cause of death by disease more than any other causes combined, even preventing development in the tropics (Gubler 1998). Of all insect vectors, Aedes aegypti proves to be the deadliest as it is the primary vector of the four most notorious vector-borne diseases – chikungunya (chik-V), Zika (Zik-V), dengue fever and yellow fever viruses. Control of the spread of Aedesborne diseases is primarily reliant on the control of the vector responsible for their spread. Traditionally, vector control relied on environmental hygiene and the elimination of breeding sites (Gubler 1998), shifting only in the 1980s to the use of synthetic chemicals in the form of carbamate, organochloride, organophosphate and pyrethroid insecticides (Norris, et al. 2015). However, the evolution of Aedes aegypti resistance to synthetic chemicals have made control of the spread of the vector and its diseases increasingly difficult. This led to the exploration of innovative and alternative methods in the control of Aedes aegypti.
The malaria epidemic was responsible for about 241 million infectious cases and 627,000 deaths worldwide in 2020.[1] This infectious disease, transmitted by the female Anopheles mosquito, is caused by parasites of the genus Plasmodium namely P. falciparum, P. vivax, P. malariae, P. knowlesi, P. ovale curtisi and P. ovale wallikeri.[2,3] Also, malaria is found predominantly in the highlands of Africa which accounts for more than 90% of infections worldwide. While there has been some success in the treatment of malaria, its eradication has been negatively impacted by insecticide and drug resistance. With emergence of thiosemicarbazone as antimalarial agents, the combination of pyridine and amide or thioamide moieties into one scaffold makes for an interesting target.[4]
The control of invasive species in crops with low tolerance are seen as a public good. This makes it a collective responsibility led by government. This is done directly through public expenditure on control measures or indirectly through incentives to people whose actions may be a contributing factor to the problem. The risks associated with invasive species have been increasing especially with globalization but are changing in nature thus warranting novel strategies for their management.
Lead, a well-known neurotoxin, remains environmentally abundant, arising from many natural and synthetic processes which encourage its environmental accumulation and hence, increased interactions with flora and fauna. Therefore, tremendous research efforts have been invested into developing various methods for its analysis and sequestration, however, affordability, sensitivity and selectivity still remain formidable challenges in this area and hence here is room for further exploration.

Loan management is a complex process that coordinates agreements among multiple stakeholders in such a way that each party benefits from the arrangement [2]. At the core of our work there is the Asset Token (ATK) which is a compliant ERC-20 token and used for all financial transactions in our proposed system. With this token in our private blockchain network [1], stakeholders can interact in a digital market. Our work includes a Non-Fungible Vehicle Token (VTK) and represents the physical vehicle. Users has access to the ownership of this NFT which prevents fraudulent transactions.
