In this interview, granted on the sidelines of the first scientific conference of the society, held at the CBN International Training Institute, Abuja, Osunkwo shares the footprints of the society and how they intend collaborate with government to boost the economy.  Excerpts:

Can you tell us how you arrived at this?

The Nigeria Society for Toxicological Sciences (NSTS) was registered with the Corporate Affairs Commission (CAC) in 2010, and, since then, we have been trying to articulate toxicological issues in Nigeria and thinking of ways to proffer solutions to concerns arising there from.

So, the body of toxicologists in Nigeria found in various universities, research institutes and private organizations have been collectively thinking about these toxicological challenges. It is against that background that we came up with the theme of our first scientific conference, which is, ‘Health, Environmental and Economic Impacts of Manmade and Naturally Released Toxicants’.

These challenges are numerous in Nigeria and we further created some themes that touched on oil and gas pollution, food toxicology, tobacco harm reduction, agricultural produce, heavy metals (lead and mercury) and industrial chemical including pharmaceuticals and pesticide toxicology, etc.

However, when the executives of the NSTS paid a courtesy call on the Hon. Minister of Science and Technology, Dr Ogbonnaya Onu, to intimate him with the conference and invite him to declare the conference open, he expressed the opinion that members of the NSTS should tackle, as a matter of urgency, scientific discourse and research on Nigerian agricultural produce.

He informed us that made in Nigeria products are being rejected abroad because of issues ranging from hygiene to fertilizers and pesticides (excessive chemical content).

The minister tasked NSTS on the need to address the issue with a view to developing systems and strategies for minimizing the challenges and making Nigerian agricultural produce more internationally competitive and acceptable.

It is a challenge that we, as members of NSTS, are pleased to take on; so, we promised him that, in the next one year, we will come up with propositions on meeting up with the challenge and finding solutions.

I am glad to say that we already have a strategy to solve this in place and immediately after this conference, during our annual general meeting, we are going to get toxicologists working in Nigeria to face the challenges. We hope to come up with an initial document that will outline measures that will be undertaken by members by way of risk assessment to proffer solutions to the challenge.

We are also poised to evolve a strategy document that would help Nigeria address toxicological issues holistically. We noticed that Nigeria has been rather reactionary on toxicological issues, merely responding to media reports on some of these incidents but we have now decided, as a society, to gather and keep a data base of toxicological challenges with informed solutions before they get out of hand

What do you intend to do with the data gathered?

We intend to apply artificial intelligence in making use of the historical data so gathered to predict the future, and be able to identify clusters of these toxicological challenges/exposures and the region they are prevalent for better planning. This is the key function of ReporTox. Once you tap the app, the app takes you to the NSTS website to guide you for report.

The NSTS would take it up from there and research will be carried out with the data collected and then government will be notified on the outcomes. We are optimistic that government will be realistic so that the people of Nigeria can benefit from it.

Which types of toxins would you say have been identified as regards health, the environment and the economy?

From our conversations so far, you would notice that there are toxins in the areas of food toxicology. One of the presentations at this conference speaks to aflatoxins. Aflatoxins are a family of toxins produced by certain fungi that are found on agricultural crops such as maize (corn), peanuts, cottonseed and tree nuts. The main fungi that produce aflatoxins are Aspergillus flavus and Aspergillus parasiticus, which are abundant in warm and humid regions of the world, one among many accountable for the rejection of Nigerian agricultural produce abroad.

What is the likely economic impact?

The immediate economic impact is that we lose a lot of foreign exchange and that affects our GDP and as a nation. The climate and temperature in Nigeria are conducive for the growth of this microorganism. We intend to identify all of them for action.

On oil and gas sector, we listened to the presentation from the studies done in Port-Harcourt and Bayelsa State; we saw clear indications of exposure by individuals to fumes, different types of gases (sulfur carbon monoxide etc) and how they affect the health of the people around the gas flaring sites, this will also be looked into.

Then for tobacco harm reduction, tobacco smoke is toxic. Though we know that about five hundred years ago, when the white people were not here yet, people were using tobacco, but nobody thought about the harm in tobacco then. People just ground it, sometimes they sniffed it or put it in their nostrils, some just wrapped it to smoke, and others rubbed it on their gums. All these happened because the nicotine in tobacco gives this feeling of wellbeing or what we call euphoria.

So people repeatedly used the tobacco but, having realized the commercial importance of tobacco, the white man made it into cigarette and brought it to us, they also studied cigarette and saw that it was not healthy. Lung cancer and many other diseases are what research studies have shown which is due to mutagens and carcinogens present in the burning of the tobacco as well as the compositions of nicotine and all other chemicals users.

Interestingly, it is also the white man that is coming up with reduced risk products that have the potential to reduce the risk of the damage to health as found in crude tobacco.
