“…Cadmium is also used in the production of plastics, fertilizers, and batteries 114,174 . Communities in LMIC, particularly low-income communities, may be chronically exposed to cadmium, an exposure that is only recently made apparent as heavy metal monitoring is implemented in communities, as illustrated by studies from Ghana and Uganda 175,176 . In fact, cadmium exposure is likely to increase in the coming decades in part due to electronic waste disposal, as seen in Nigeria, 202 .…”

Summary Environmental exposures in low- and middle-income countries lie at the intersection of increased economic development and the rising public health burden of cardiovascular disease. Increasing evidence suggests an association of exposure to ambient air pollution, household air pollution from biomass fuel, lead, arsenic, and cadmium with multiple cardiovascular disease outcomes including hypertension, coronary heart disease, stroke, and cardiovascular mortality. While populations in low- and middle-income countries are disproportionately exposed to environmental pollution, the bulk of evidence that links these exposures to cardiovascular disease is derived from populations in high-income countries. More research is needed to further characterize the extent of environmental exposures and develop targeted interventions towards reducing cardiovascular disease in at-risk populations in low- and middle-income countries.

“…According to Guan et al (2014), geo-accumulation index is suitable for assessing heavy metals in soil contaminated by industrial activities. Geo-accumulation index by Muller (1969) and have been applied by El-Metwally et al (2017), Bhutiani et al (2017), Ghaleno et al (2015), Todorova et al (2016), Tang et al (2014) Wang et al (2016, Hassaan et al (2016), Vowotor et al (2014), Ghazaryan et al (2015), Guan et al (2014), Gasiorek et al (2017), Kowalska et al (2016).…”

-accumulation index, enrichment factor and quantification of contamination of heavy metals in soil receiving cassava mill effluents in a rural community in the Niger Delta region of Nigeria, Molecular Soil Biology, 8(2): 7-20 (doi: 10.5376/msb.2017.08.0002) Abstract This study investigated enrichment factor, geo-accumulation index and quantification of contamination of heavy metals in cassava mill effluents contaminated soil by smallholder cassava processors in a rural community in the Niger Delta region of Nigeria. Data used for the environmental risk assessment is from secondary sources. The assessment was carried out under two background scenarios viz: geometric (BGM) and median mean (BMM). 50% of mean detected individual metals was used as mean data for location that the metal was not detected. Assessment was carried out following well established protocol. Results showed that enrichment factor (EF), geo-accumulation index (Igeo), improved Nemerow Index (INI), Metal enrichment index (MEI) and quantification of contamination (QoC) in soil heavy metals (viz: Fe, Cr, Zn, Cu, Co, Ni, Mn, Pb and Cd) receiving cassava mill effluents in a rural community of the Niger Delta region of Nigeria revealed un-contamination to moderately contamination for Igeo, NMI, background rank to significant enrichment for EF, no enrichment to moderate enrichment for MEI, and positive values of quantification of contamination is an indication of pollution/contamination due to anthropogenic sources. The study further showed that cassava mill effluents are contributing to soil heavy metal contamination in study area.

“…CD is the sum of all contamination factors, which provides information about total contamination in a particular sampling location (Singovszka et al, 2014;Bhutiani et al, 2017). Contamination degree is often expressed based on the formula previously described by Hakanson (1980) and have been applied by Bhutiani et al (2017), Uriah and Shehu (2014), Singovszka et al (2014), Soliman et al (2015), Todorova et al (2016), Ghaleno et al (2015), Fiori et al (2013), Karydas et al (2015), Zhu et al (2012), Elias et al (2014), Mohseni-Bandpei et al (2016), Swarnalatha et al (2013), Hassaan et al (2016), Vowotor et al (2014), Ghazaryan et al (2015), Qingjie et al (2008), Odukoya et al (2016).…”

Cassava mill effluents are discharged into the environment by smallholder cassava processor in rural communities in the Niger Delta region of Nigeria. Cassava mill effluents are known to induce toxicity in some biodiversity such as livestock (sheep, goat), vegetation, microorganisms and fisheries. This study evaluated the pollution load indices of heavy metals in cassava mill effluents contaminated soil in rural community in the Niger Delta region of Nigeria. Secondary data from cassava mill effluents soil were used for the study. The data were classified based on seasons. The pollution load was calculated following standard protocol. Nine pollution indices were considered including Contamination factor (CF), Degree of contamination (CD), Pollution load index (PLI), Pollution index (PI), Sum of pollution index (SPI), Pollution index/ Contamination Index (PI/CI), Metal pollution Index (MPI), Average Pollution Index (API) and Nemerow integrated pollution index (NIPI). In few instance that some heavy metals was not detected, 50% of mean detected individual metals were considered for the location that the metals were not detected. Geometric (BGM) and median mean (BMM) were considered for the background scenarios except for API and PI/CI in which median mean was used. The pollution load resulting from these heavy metals viz: Fe, Cr, Zn, Cu, Co, Ni, Mn, Pb and Cd revealed that CF and CD had low to moderate contamination level in both seasons apart from Pb that had considerable pollution in one of the locations for wet season, PLI were within no pollution to moderate pollution, PI were also within no pollution to low pollution level and NIPI were within warning line of pollution to low level of pollution for dry season, and warning line of pollution to high pollution in wet season. MPI, PI/CI and API showed slight pollution. The findings of this study also showed that cassava processing by smallholder in rural communities in the Niger Delta is slightly contributing to heavy metals pollution is receiving soil which varies according to seasons. Furthermore, age and heavy metal content in the cassava tuber and quantity of cassava processed in each mill and other anthropogenic activities could account for difference in pollution among the various locations, while runoff resulting from rainfall could account for the seasonal influence.
