Abstract

Cement is widely used in the building industry because it is reliable and because its basic ingredients are inexpensive and abundant. However, the production of cement produces heavy metal-laden dust that can harm humans and the environment. This study aimed to determine the risk posed by heavy metals in the soil around a cement company in Sokoto, Nigeria. Soil samples were obtained at 0.1, 0.5, and 1.0 km from the company and served as test samples, while control samples were obtained at 5.0 km away. The soil samples were treated and assayed for lead (Pb), cadmium (Cd), copper (Cu), and zinc (Zn) using atomic absorption spectroscopy. The values obtained were used to estimate the heavy metals’ average daily inhalation (ADI), average daily dermal exposure (ADDE), hazard quotient (HQ), health risk index (HRI), and carcinogenic risk (CR). Permissible levels of all the heavy metals were detected at all the locations (0.1 > 0.5 > 1.0 > 5.0 km). However, the ADI, ADDE, HQ, HRI, and CR of the heavy metals were above the permissible limits. It can be inferred from the results that the soil around the company can predispose humans to heavy metal toxicities. Consequently, the company needs to prioritize pollution control.

Abstract

The most common and cost-effective waste disposal method is the dumpsite; however, leachate from dumpsites may percolate and compromise groundwater sources. This study evaluated the levels of heavy metals (lead, cadmium, chromium, copper, and arsenic), physicochemical parameters (pH, electrical conductivity, total dissolved solids, hardness, calcium, magnesium, and chloride), and microorganisms in borehole water samples obtained at distances of 50, 100, 200, and 400 meters from the Igando dumpsite in Lagos, Nigeria. The health hazards associated with the heavy metals were also calculated. Physicochemical analysis indicated that the water samples were acidic, with pH values ranging from 4.30±0.01 to 5.21±0.008. They contained levels of calcium (166.73±0.01 - 328.66±0.06 mg/l), magnesium (83.72±0.02 - 119.40±0.17 mg/l), hardness (416.01±0.11 mg/l - 820.00±1.63 mg/l), and chloride (20.07±0.02 - 120.90±0.81 mg/l) that exceeded the limits set by the World Health Organization. Heavy metal analysis showed that, in all locations, lead exceeded the permissible limits, cadmium exceeded the limits except for the 400-m location, and copper, chromium, and arsenic (except for the 50-m location) were within permissible limits. The average daily intake and hazard quotient of the heavy metals were both within recommended limits, but the carcinogenic risks of lead, cadmium, and copper in water collected at a distance of ≤100m exceeded the threshold. Microbiological examinations revealed non-permissible levels of bacteria at all locations, coliforms at the 400-m location, and fungi at the 50-m and 400-m locations. On average, the parameters significantly (p<0.05) increased in concentrations as the proximity to the dumpsite decreased. These findings indicate that borehole water is not suitable for drinking without treatment.

Abstract

Ikorodu Lighter Terminal is an important lagoon port in Lagos, Nigeria. However, the intense anthropogenic activities that take place around the port could potentially pollute the water. This study assessed the safety of human exposure to the water around the port. Samples of the water were assayed for physicochemical parameters, namely: electrical conductivity, biochemical oxygen demand (BOD), total suspended solids (TSS), total dissolved solids (TDS), pH, turbidity, hardness, calcium, chloride, sulphate, nitrite, and phosphate. Moreover, heavy metals, including lead, manganese, copper, cadmium, nickel, and chromium, were analyzed, and their values were used to estimate potential health risks. Also assayed was the presence of microorganisms. The water samples had non-permissible levels of nitrite, oil and grease, and BOD. The concentrations of the heavy metals as well as their average daily ingestion and average daily dermal exposure were within the tolerable limits, except Ni. However, their hazard quotient and carcinogenic risk via ingestion and dermal contact exceeded the tolerable limits. Safe levels of bacteria, coliforms, and fungi were detected in the water. Based on these results, the water may expose users to health hazards. There is a need for policies geared towards the safety of human exposure to the water.

Abstract

Fruits in Birnin Kebbi, Nigeria, are often preserved using chemicals to extend their shelf life, maintain freshness, and enhance quality and taste. However, global concerns persist about the safety of these preservatives, particularly when applied indiscriminately. This study aimed to determine the demographic characteristics of fruit sellers in Birnin Kebbi and the preservatives they commonly use. Structured questionnaires were administered to 200 participants who provided informed consent. The results showed that 116 (58%) of the respondents were male, while 84 (42%) were female. Most participants (38%) were aged 18–25 years (76 individuals), followed by those aged 26–35 years (60 individuals, 30%). A significant proportion of participants (82; 41%) had no formal education, while 48 (24%) had primary education. The majority of participants (120; 60%) belonged to the Hausa ethnic group, and 156 individuals (78%) identified as Muslims. Marital status was evenly distributed, with 84 participants (42%) being single and 80 (40%) married. Regarding fruit preservation practices, watermelon was the most frequently preserved fruit, cited by 50 participants (25%), followed by oranges (42; 21%) and bananas (22; 11%). Among chemical preservatives, sulfite was the most commonly used, reported by 84 (42%) participants, followed by citric acid (36; 18%), sodium benzoate (28; 14%), calcium chloride (24; 12%), benzoic acid (18; 9%), and ethanol (10; 5%). Alarmingly, 95% of participants demonstrated inadequate knowledge of proper preservative application methods, raising concerns about potential health risks for consumers. These findings suggest that fruit preservation practices in Birnin Kebbi may expose consumers to health hazards. It is imperative to educate fruit sellers and consumers on the safe use of chemical preservatives, including appropriate concentrations and application techniques, to mitigate these risks and promote safer fruit consumption.
