Abstract

Background: The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults.
Methods: Water samples from groundwater used for drinking were collected from different water sources (over 22) and fluoride levels were determined through spectrophotometer, DR/5000 (Hach).
Results: The mean fluoride concentration was 1.14 ppm. The maximum concentration of fluoride recorded was 1.78 ppm while the lowest was 0.85 ppm.
Conclusion: Semnan drinking water is suitable for consumption without any treatment.

Abstract

Background: Bisphenol A (BPA) is one of the hazardous materials causing disruption of endocrine pathways. Due to water contamination by this component from multiple sources and the associated health problems, BPA has been the focus of multiple studies. It has been proved that BPA may cause harm because of its impact on estrogenic receptors in human and other organisms.
Methods: In this study, the presence of Bisphenol A in bottled drinking water in Iran was evaluated by solid phase extraction (SPE) and gas chromatography (GC). Compared to other studies measuring the level of Bisphenol A in milk, surface water, and wastewater, the present study focused on the levels of Bisphenol A in bottled drinking water to determine the safety risk level of BPA as a possible public health issue.
Results: The results showed no evidence of BPA at levels above the standard within all analyzed samples.
Conclusion: It seems that BPA is a low-risk component in bottled drinking water.

Abstract

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 (hand-dug 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.
