“…These were found present at monthly mean concentrations of between 24 and 139 mg/L in the lagoon and 10 and 80 mg/L in the receiving stream. Adeniyi et al (2008) looked at concentrations of phthalates in soils surrounding an open solid waste dump in Limpopo Province, South Africa. For the phthalate esters dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP) and DEHP, the mean values calculated were 0.31 ± 0.12, 0.21 ± 0.05, 0.30 ± 0.07, and 0.03 ± 0.01 mg/kg respectively.…”

Urban groundwater quality in sub-Saharan Africa: current status and implications for water security and public health

Groundwater resources are important sources of drinking water in Africa, and they are hugely important in sustaining urban livelihoods and supporting a diverse range of commercial and agricultural activities. Groundwater has an important role in improving health in sub-Saharan Africa (SSA). An estimated 250 million people (40% of the total) live in urban centres across SSA. SSA has experienced a rapid expansion in urban populations since the 1950s, with increased population densities as well as expanding geographical coverage. Estimates suggest that the urban population in SSA will double between 2000 and 2030. The quality status of shallow urban groundwater resources is often very poor due to inadequate waste management and source protection, and poses a significant health risk to users, while deeper borehole sources often provide an important source of good quality drinking water. Given the growth in future demand from this finite resource, as well as potential changes in future climate in this region, a detailed understanding of both water quantity and quality is required to use this resource sustainably. This paper provides a comprehensive assessment of the water quality status, both microbial and chemical, of urban groundwater in SSA across a range of hydrogeological terrains and different groundwater point types. Lower storage basement terrains, which underlie a significant proportion of urban centres in SSA, are particularly vulnerable to contamination. The relationship between mean nitrate concentration and intrinsic aquifer pollution risk is assessed for urban centres across SSA. Current knowledge gaps are identified and future research needs highlighted.

“…The instrument's setting and operational conditions were done in accor- dance with the manufacturers' specifications. The instrument was calibrated with analytical grade metal standard stock solutions (1,000 mg dm −3 ) in replicate (Adeniyi et al 2008). Five grams of predigested soil samples were spiked with metal standards in triplicate for metal recovery studies as reported earlier (Awofolu 2005;Adeniyi et al 2005).…”

This study reports the level of total petroleum hydrocarbons (TPH) and trace heavy metals (lead, copper, and cadmium) in soil samples collected randomly from Iyana-Iba garage, Lagos State University bus stop, Adeniran Ogunsanya College of Education bus stop, and a control site off Lusada-Atan road, near Crawford University, Igbesa, Ogun state. TPH was estimated gravimetrically after Soxhlet extraction and column clean up, while soil metals were determined by atomic absorption spectrometry using mineral acid digestion. For TPH, the sites have mean values of 19.43+/-1.27, 16.11+/-1.85, and 11.43+/-4.33 mg/g with a control mean value of 0.33+/-0.16 mg/g. For trace heavy metals, cadmium was not detected. However, the mean levels of lead are 4.24+/-3.10, 3.72+/-0.60, and 3.70+/-1.32 microg/g, respectively, whereas mean copper concentrations are 20.63+/-9.02, 19.35+/-3.61, and 16.76+/-3.02 microg/g in all sites, respectively, compared to the control mean of 0.25+/-0.13 and 5.99+/-1.23 microg/g for lead and copper, respectively. Sites studied have higher levels of TPH and metals compared to the control soil samples. This is indicated by a statistically significant difference found between the concentration of analyzed elements in soils collected along Lagos-Badagry expressway and the control site.

“…Of these groups of chemicals are Phthalates or phthalic acid esters (PAEs). They are diakyl or alkyl esters of 1,2 benzene carboxylic acid (Luks-Betlej et al, 2001;Alatriste-Mondragon et al, 2003;Adeniyi et al, 2008). They are formed when methanol, ethanol or other alcohols react with the carboxyl groups on the benzene ring of phthalic acids.…”
