“…KNUST, a university in Kumasi, has minimal vehicular motion and no industrial activities. In previous studies, heavy metals and metalloid levels in KNUST soils were low compared to recommended levels (Akoto et al 2016;Akoto et al 2017). In addition, particulate matter and soil samples from KNUST have been used as controls in previous studies of environmental contaminants (Bortey-Sam et al 2013;Bortey-Sam et al 2014;).…”

“…The growing rate of industrialization (including mining), and resulting increases in economic activity and population growth in Kumasi, Ghana, has led to increased pollution of the environment (Bortey-Sam et al 2014). Studies of environmental contamination and possible health risks due to metal exposure via medicinal herbs (Nkansah et al 2016a) , geophagic white clay (Nkansah et al 2016b), food (Nkansah et al 2016c), dust (Nkansah et al 2015), soils (Akoto et al 2016;Akoto et al 2017) and streams (Akoto et al 2010) within Kumasi metropolis have been reported. Furthermore, levels of zinc, arsenic, copper and nickel in livers of wild rats sampled in Kumasi were higher compared to the levels in wild rats sampled around mining sites in Kabwe, Zambia (Nakayama et al 2013).…”

Heavy metals and metalloids contamination in soils, water, food and livers of wild rats have been studied in Kumasi, Ghana and despite the estimated risks to residents, there is no epidemiological study to ascertain these projections. In addition, the World Health Organization and International Agency for Research on Cancer have reported an increase in respiratory diseases and cancers, in Ghana. The study's purpose was therefore to explore the potential associations between metal exposure and occurrences of respiratory diseases, lipid peroxidation and/or DNA damage to different age groups and sexes in Kumasi. Human urine was collected from the general population in urban and control sites in Kumasi and nine metals were measured in each sample. Results showed that although Zn was the most abundant total urinary As concentration was higher in 83% of samples compared to reference values. Urinary concentrations of metals, malondialdehyde (MDA) and 8-hydroxy-2-deoxy-guanosine (8-OHdG) were higher in urban sites compared to the control site. Based on the results obtained, there was no significant correlation between urinary metals and age. However, urinary Cd and MDA were highest in age groups 61-85 and 3-20 years, respectively. Significantly higher levels of urinary Co, As and Cd were detected in female participants. The study revealed that exposure to As was significantly associated with increased odds of asthma (odds ratio (OR) = 2.76; CI: 1.11-6.83) and tachycardia (OR = 3.93; CI: 1.01-15.4). Significant association was observed between urinary metals and MDA and 8-OHdG indicating possibility of lipid peroxidation and/or DNA damage in Kumasi residents.

Purpose The purpose of this study is to collaborate with environmental engineering and management making an effort to provide evidence for the irresponsible behavior of small business set up in north India with special reference to Aligarh City. Corporates have huge accountability for sustainable development, and they cannot overlook the major responsibilities which are lying on their shoulders. CSR is related to the concept of “doing good” but, beyond “doing good” businesses have the responsibility for “avoiding bad” to avoid corporate social irresponsibility (CSI), such as damaging the environment by polluting land, water and air, cheating customers, violating human rights, or doing any unethical practices. Design/methodology/approach In this study, random groundwater samples were collected from “Aligarh Nagar Nigam” installed hand pumps from industrial influence areas of Aligarh during the month of October and November 2017. These samples were collected nearby small-scale metal plating industries plants. The samples analyzed by the Atomic Absorption Spectrometer (AAS) Perkin Elmer PinAAcle 900 F, for Fe, Mn, Pb, Zn, Cu and Cr (Jahromi et al., 2007; Chen and Teo, 2001; Bidari et al., 2007; Land and Hoops, 1973; de Oliveira et al., 2016; Akoto et al., 2016). In addition, some other parameters also taken in this study and the results obtained are compared with the World Health Organization (WHO) and Bureau of Indian Standard (BIS). Findings These results of the study revealed that the penetration of heavy metals like Cr, Pb, Cu, Zn, Fe and Mn into the soil is found much higher than the permissible limit stated by the government. The concentrations of metals in groundwater found to be within limits, but some metals are exceeding the standard limits in few samples. Concentrations of these heavy metals Cr>Cu>Pb>Fe>Mn are exceeding standard limits, Zn found within permissible limits as per WHO and BIS standard. This result proves to be a means to an end for an irresponsible behavior toward the society and environment which leads to serious health and environmental hazards. Research limitations/implications The results are beneficial for data generation on various quality parameters of groundwater. The results of this study help in proper decision-making by concerned authorities to prevent, reduce toxic levels and begin to take steps for making water fit for drinking and other purposes. The research is limited in Aligarh City and other cities are like Kanpur, Noida and Ghaziabad are also tested by taking samples of water, as these cities are extensively captured by SME’s and large scale industries. Practical implications The results of this study have several implications for both governmental and non-governmental practice and policy development. As society expects positive attitudes of the businesses toward CSR activities and concern about the environment, businesses, institutions and governments should pay more attention to promote the initiative of environment safety to intensify their public concern. The small business unit must know about the serious health hazards of discharging the waste water in the open and therefore regular checking of heavy metal contamination in the groundwater in these areas is needed and use of contaminated water must be prevented to lessen the health risk caused by using the metal contaminated groundwater. The small-scale industries should follow the guidelines for proper disposal of wastewater discharge. The water treatment technology should involve and take possible steps to remove heavy metals contamination. Originality/value This study provides real data to municipality and other government offices which can be used as a benchmark to plan strict policy to prohibit the open discharge of wastewater by industries.

“…The mixtures were swirled gently and slowly at a moderate heat on the digester for 15 minutes and allowed to cool down, and later diluted with 50cm 3 of distilled water. The mixture was filtered through a filter paper into a 100cm 3 volumetric flask and used for test using the Atomic Absorption Spectrophotometer (AAS) (Akoto et al 2016, Tijani et al 2007). The results of the tests remitted the followings: It was discovered that soils of the waste dump sites were enriched with the heavy metals (Zn, Cu and Cd) more than the adjacent soils (control) but were still within critical levels.…”

This study assessed the nature of solid waste generation, its spatio-temporal pattern and existing management strategies in Sokoto metropolis. The greatest challenges facing cities in the developing world are; paucity of solid waste management and control. In the Nigeria context, solid waste management is characterized by inefficient collection, insufficient coverage of the collection system and improper disposal methods. In Sokoto metropolis, increase in population has resulted into accelerated of solid waste generation with pollution of all categories, and the consequent is dearth of modern management. The study used; selection of different wastes for observation, sampling-up four sub-soils at 0-30cm at random from each of the waste dump sites to determine not only for heavy metal concentrations but also for fertility supplement in comparison with the National Environmental Standard and Regulation Enforcement Agency (NESREA). Also, fifty scheduled questionnaires were administered each on selected residents around dumped sites and to the staff of Town Planning Board to solicit for relevant information on government and its agencies effectiveness in disposal and management of waste. Landsat data was also used to map out the waste sites for spatio-temporal analysis from 1999 to 2016. Results are expected to inform major decisions makers and urban planners in order to promote a sustainable urban development for Sokoto metropolis and its environs.
