According to the United Nations environmental program, lead (Pb) is a heavy metal that is toxic even at very low exposure levels and has acute and chronic effects on human health. In the environment, lead (Pb) is also toxic to plants, animals and micro-organisms. Lead (Pb) can originate from human activities (anthropogenic) or from natural sources (geogenic). Lead poisoning occurs when humans especially children are exposed even to low levels of lead (Pb).

Lead (Pb) poisoning is a serious health problem globally and almost every county in United States has a childhood lead (Pb) poisoning prevention program. Studies carried out in Benin, Cameroon, Côte d’Ivoire, Egypt, Ethiopia, Guinea, Kenya, Morocco, Mozambique, Nigeria, Sudan, Tanzania, Togo, Uganda, and Zambia found some paints sold for home use containing extremely high lead levels of up to 100,000 ppm. These concentrations are several times more than the 90 ppm United Nations recommended limit of lead (Pb) in paint.

Many people know so little or nothing about lead (Pb) poisoning. To create awareness on this health problem, I have developed an educational outreach program which has now  more than 10,000 followers living in 23 countries including United States. Most of my audience is from sub-Saharan Africa which has experienced the largest known childhood lead (Pb) poisoning outbreak but with almost no awareness on digital platforms. To the best of my knowledge, this program is the largest and first of its kind in addressing childhood lead (Pb) poisoning in sub-Saharan Africa through social media network sites.

My educational outreach is through this website which is connected to a Facebook page and group. The Facebook page, group, and this website provide links to free credible information on childhood lead (Pb) poisoning. The Facebook page is connected to Facebook group under different names. The Facebook group and the links below allows you to access free downloadable pdf materials on childhood lead (Pb) poisoning for use and sharing with the goal of reaching as many people as possible.

My PhD research is on Fate and Transport of Anthropogenic Lead (Pb) along the Arid Section of Route 66, San Bernardino County, California. Fate and transport research project can be defined as the study of how chemicals degrade and where they travel in the environment when they are released intentionally or unintentionally. Transport is how chemicals move through the air, water and soil and fate is how chemicals change in the environment.

In my study area, anthropogenic lead (Pb) along Route 66 is mainly from leaded gasoline and it was deposited during the leaded gasoline era. Spatial distribution and surface transport mechanism of anthropogenic lead (Pb) along the arid section of Route 66 in San Bernardino County, California is my first PhD research project. Lead (Pb) chemical fractionation along the arid section of Route 66 in San Bernardino County, California is my second PhD research project. My third PhD research project is to develop an  educational outreach program on childhood lead (Pb) poisoning with a focus on populations at risk of lead (Pb) poisoning.

Scientific Research on Lead Poisoning.
   THE LARGEST KNOWN OUTBREAK OF LEAD POISONING IN HISTORY.

The worst documented case of childhood lead (Pb) poisoning outbreak occurred in Zamfara State, Northern Nigeria where about 400 children died and thousands more were disabled in the artisanal gold mining villages (Dooyema et al., 2012; Plumlee et al., 2013). The outbreak was discovered in 2010. Gold ores with lead (Pb) rich veins were mined manually and were transported in household bags to the villages for processing (Plumlee et al., 2013). First stage of ore processing involved breaking down the lead (Pb) rich gold ores manually using hammers followed by manual grinding of the broken ore fragments using household mortars and pestles or mechanical grinding by gasoline-powered flour mills that also were used to grind grains for the villagers (Plumlee et al., 2013). The grinding of lead (Pb) rich gold ores generated large amounts of lead (Pb) rich dust.

To concentrate gold particles, ground lead (Pb) rich gold ores were washed with a shower of water at the village water sources and then the concentrates were combined with liquid mercury manually in household cooking pots to form a gold-mercury amalgam which allows minute pieces of  gold to be extracted when mercury is vaporized (Plumlee et al., 2013). The villagers were significantly exposed to mercury which is also dangerous to human health. United States Environmental Protection Agency (EPA) has mercury free gold mining techniques for artisanal and small scale gold mining (ASGM). Older children worked with their family members at the processing and sometimes  processing and storage of lead (Pb) rich gold ores occurred where children played and lived (Plumlee et al., 2013). 

Researchers found that surviving children < 5 years old had Blood Lead Levels (BLL) up to 370 µg/dL (Dooyema et al., 2012). CDC recommends Blood Lead Level (BLL) be < 3.5 µg/dL. Worse off, soils contaminated by washing wastes were used to make bricks for building houses in the villages (Plumlee et al., 2013). There was high lead (Pb) exposure at all stages of gold mining and processing in these artisanal gold mining villages and that is how the worst documented lead (Pb) poisoning disaster occurred. Several agencies responded to this outbreak and the situation has improved but a lot more has to be done to avoid future outbreaks. This educational outreach program has made deliberate online efforts to target the affected artisanal gold mining villages in Zamfara State, Nigeria with links to credible digital educational materials on lead (Pb) poisoning.

WORK  HISTORY

Graduate Research Assistant, Loma Linda University, California : 2012- Present.

My role is to manage scientific research projects and conduct scientific research under the guidance of my research advisor. Research project management involves grant applications, planning and organizing scientific analytical work, making presentations at professional scientific meetings, and documentation of scientific data. Research project management involves all aspects of project management life cycle. My scientific research is on sedimentary geology and environmental geology/geology and health. My work on sedimentary geology started in 2012 and it involved intense laboratory work and several field research in the Mojave Desert near Death Valley where I studied the sedimentology of the Neoproterozoic Kingston Peak Formation. My sedimentology work earned me a Master of Science degree in Geology in 2016.

I started my work on environmental geology in fall 2016 for my PhD in Earth Science. This work also involved intense laboratory work and several field research along Route 66 near Barstow, California where I studied the Fate and Transport of Anthropogenic lead (Pb) that was deposited during the leaded gasoline era. The field research and laboratory work for my environmental geology research is complete and currently am writing my PhD dissertation with goal of graduating in summer 2023.

My last PhD project involves developing an educational outreach program on childhood lead (Pb) poisoning with a focus on populations at risk of lead (Pb) poisoning. Childhood lead (Pb) poisoning is a health problem related to my PhD research in environmental geology. My educational outreach program is through social media and this website. My responsibility in this program includes creation and management of owned media (website, Facebook page and group), setting up, optimizing, and analyzing educational campaigns in digital marketing platforms such as Facebook App, Instagram, and Messenger. My current role is centered around PhD dissertation writing, digital marketing, and project management.
