“…Evidence of bioaccumulation was shown by report of higher serum levels of Cd in occupationally exposed individuals; cement factory workers and residents near cement factory compared to unexposed controls [10]. Occupational exposures to Cd have been associated with renal tubular dysfunction with hypercalciuria, renal stone formation, osteomalacia, and osteoporosis [2,18]. Cadmium has also been implicated in respiratory and immune dysfunctions [19,20].…”

“…Exposure to high Pb levels has been associated with a wide range of effects, including various neuro developmental effects, mortality (mainly due to cardiovascular diseases), impaired renal function, hypertension, impaired fertility and adverse pregnancy outcomes. Impaired neurodevelopment in children is generally associated with lower blood lead concentrations than the other effects [2,14]. The detrimental effects of Pb contamination of drinking water on the neurodevelopment and intelligience quotients of children residing in quarry site camp of the cement factory are unimaginable.…”

“…Though, most elements are essential for proper functioning of the human biological system [4], humans are not adapted to deal with them at concentrations higher than the reference values that can be tolerated by the human homeostasis [2,3,5]. Cement factories have been a major source of heavy metals emission to the environment with several reports showing higher concentrations of heavy metals around cement factories [6][7][8].…”

“…Contamination of the environment by major and trace elements is a public health problem, as most of these elements are indestructible, toxic, bio-accumulate and poses a serious threat to human life and the environment [1][2][3]. Though, most elements are essential for proper functioning of the human biological system [4], humans are not adapted to deal with them at concentrations higher than the reference values that can be tolerated by the human homeostasis [2,3,5].…”

“…The particulate matter that is emitted from quarrying of limestone to the final process of packaging of cement is deposited on the soil, vegetation and water bodies, which usually serve as drinking water sources in the environment, thus increasing the pollution quotient of the surrounding communities [9]. The quality of water influences the health status of any population; elemental contamination of drinking water sources above the WHO threshold limit for particulate metal concentration has been associated with deleterious health effects including risk for cancers, cardiovascular, renal hepatocellular, neuromuscular, gastrointestinal, skeletal, hematological and immunological diseases [2]. Cement dust deposition in water have been associated with changes in salt content of water leading to serious disruption of aquatic habitat and decrease quality of water used for drinking and irrigation [8].…”

Background: Cement production is associated with heavy metal emissions and environmental pollution by cement dust. The degree of contamination of drinking water sources by major and trace elements present in cement dust generated by united cement factory (UNICEM) is still uncertain. This study estimated the element content of ground and surface water samples (handdug wells, boreholes and streams) around the factory site to determine the impact of cement dust exposure on the water levels of these elements.Methods: This study was conducted at UNICEM at Mfamosing, Akamkpa local government area, Cross River State, Nigeria. Drinking water samples (5 from each location) were collected from the cement factory quarry site camp, 3 surrounding communities and Calabar metropolis (45 km away from factory) serving as control. The lead (Pb), copper (Cu), manganes (Mn), iron (Fe), cadmium (Cd), selenium (Se), chromium (Cr), zinc (Zn) and arsenic (As) levels of samples were determined using Atomic Absorption Spectrometry (AAS). Data were analyzed using ANOVA and LSD post hoc at P = 0.05. Results:As and Pb content of samples from camp were above the WHO recommendations of 0.01mg/l and 0.01mg/l respectively. Chromium and cadmium content of all water samples were above and others below WHO recommendations. Water levels of Mn, Fe, Zn, As, Se, Cd, Ca and Si were significantly elevated (though below WHO recommendations) in camp than other locations (P<0.05). Conclusion:Production of cement results in As, Pb, Cr and cd contamination of drinking water sources near the factory. Treatment of all drinking water sources is recommended before public use to avert deleterious health consequences.

This study examined the physical, chemical, and heavy metals in groundwater from boreholes and hand‐dug wells at the Lafarge cement factory environment at Sagamu, Ogun State, Nigeria. Water samples were obtained from 20 sampling locations during the wet and dry seasons of 2019. The 17 parameters determined include the pH, temperature, electrical conductivity, total dissolved solids (TDS), total hardness, alkalinity, salinity, chloride, sulfate, phosphate, nitrate, calcium, magnesium, copper, lead, iron, and cadmium. The samples were analyzed using titrimetric and spectrophotometric methods. Correlation analysis was applied as part of the analytical tool in this study. The result indicated low physiochemical concentration of pH, total hardness, sulfate, nitrate, chloride, magnesium, calcium (>1% to 15%), and electrical conductivity (>1000 μS/cm) and fell within the Standard Organization of Nigeria (SON) and World Health Organization (WHO) desirable and maximum permissible limits for potable water during the wet and dry seasons. However, phosphate was above the standard limit for portable water of 6.5 mg/L in all sampling locations, whereas the total alkalinity was above the WHO standard limit (200 mg/L) in 12 locations in the wet seasons and a location in the dry season. Salinity was also above standards in one and four locations in the wet and dry seasons, respectively. Lead and cadmium were not detected in most locations, whereas iron, lead, cadmium, and copper were above standard limits in some locations. A significant relationship exists between the heavy metals and some of the physiochemical parameters at p ≥ .05 and p ≥ .01. The polluted water in most locations is capable of resulting in an adverse health hazard. Thus, this study explains the effect of physicochemical and heavy metals on water management at Sagamu and is important for water resource planning.
