Environmental pollution is a major issue which confronts industry and business in today’s world on daily basis. Industrial activities are the leading cause of metals emission, often associated with soil and plant metal concentration in adjacent regions. Cement industry is one of the 17 most polluting industries listed by the central pollution control board (CPCB). Impact of dust deposition from Cement Company of Northern Nigeria on the proximate and phytochemical concentrations of lettuce (Lactuca sativa) was studied. A comparative study of heavy metal concentration and phytochemicals of Lactuca sativa and soil samples from Kalambaina (Industrial area) and Kwalkwalawa (non-Industrial area) were estimated using atomic absorption spectrophotometry (AAS) and standard analytical procedures respectively. Result of quantitative phytochemical analysis revealed significant difference (P<0.05) in all parameters. Heavy metal values of Pb(0.012±0.002 mg/g), Zn(0.043±0.003 mg/g), and Ca(706.860±14.980 mg/g) in Lactuca sativa collected from Kalambaina revealed significant difference (P<0.05) when compare to samples collected from Kwalkwalawa and WHO standard. In addition, the heavy metal concentration in soil collected from Kalambaina showed significant difference (P<0.05) when compare to samples collected from Kwalkwalawa; with the highest value recorded in Ca (974.25±48 mg/g) which might be as a result of activities in the cement industry. Conclusively, plants grown at cement industries might not be safe for consumption

The study analyses the health risk assessment of the concentration of Iron, Lead, Copper, Chromium, and Cadmium heavy metals in vegetables grown near dumpsites of Jimeta and Ngurore areas of Adamawa State, Nigeria. Vegetables mainly Spinach (Spinacia oleracea) and lettuce (Lactuca sativa) were collected in triplicates and analyzed using Atomic Absorption Spectrophotometer Buck 210VGP (AAS). The result revealed that heavy metals detected in spinach at Jimeta dumpsite decreased in the following order: Fe (3.7 mg/kg) > Pb (0.18 mg/kg) > Cu (0.12 mg/kg) > Cr (0.07 mg/kg) > Cd (below limit of detection), compared to the metal concentration in spinach at Ngorure dumpsite with lower concentration of heavy metal which decreased in the order of: Fe (2.5 mg/kg) > Pb (0.16 mg/kg) > Cu (0.14 mg/kg) > Cr (0.02 mg/kg) > Cd (below limit of detection). Other result for Spinach in Jimeta decreased in the order Fe (3.31mg/kg) > Pb (0.2mg/kg) > Cu (0.11mg/kg) > Cr (0.05mg/kg) > Cd (ND) beyond the limit of detection while Lettuce decreased in the order Fe (22.54mg/kg) > Cu (0.31mg/kg) > Pb (0.12mg/kg) > Cr (0.07mg/kg) > Cd (ND) beyond the limit of detection. Fe is the most abundant element in the vegetables with a mean value of 21 mg/kg followed by Pb (0.177 mg/kg). The analyses of paired T-test for vegetables in Ngurore and Jimeta at 0.05 level of significant confirmed that Cu and Cr showed no statistically significant difference in their concentration level while Fe and Pb confirmed that there was statistically significant difference in their concentration level. However, the detection of heavy metals in these vegetables calls for close environmental monitoring and adequate public awareness. This is necessary to discourage further pollution which could lead to high metal concentration and metal poisoning in vegetables and invariably humans that consume them.

Heavy metal ions contamination has become more serious which is caused by the releasing of toxic water from industrial area and landfill that are very harmful to all living organism especially human and can even cause death if contaminated in small amount of heavy metal concentration. Currently, peoples are using classic method namely electrochemical treatment, chemical oxidation/reduction, chemical precipitation and reverse osmosis to eliminate the metal ions from toxic water. Unfortunately, these methods are costly and not environmentally friendly as compared to bioadsorption method, where agricultural waste is used as biosorbent to remove heavy metals. Two types of agricultural waste used in this research namely oil palm mesocarp fiber (Elaesis guineensis sp.) (OPMF) and mangrove bark (Rhizophora apiculate sp.) (MB) biomass. Through chemical treatment, the removal efficiency was found to improve. The removal efficiency is examined based on four specification namely dosage, of biosorbent to adsorb four types of metals ion explicitly nickel, lead, copper, and chromium. The research has found that the removal efficiency of MB was lower than OPMF; whereas, the multiple metals ions removal efficiency decreased in the order of Pb2+ > Cu2+ > Ni2+ > Cr2+.
