“…Our results showed a reduction in the growth and physiology of sunflower in lead contamination as compared to plants grown in uninoculated treatment without contamination. These findings are similar to those of Hussain et al (2006Hussain et al ( , 2013 and McComb et al (2012). It is known that the reduction in plant growth by lead contamination might be due to its interference with the uptake of nutrients, respiration, photosynthetic rate and cell membrane permeability (Sharma and Dubey 2005).…”

The problem of environmental pollution is a global concern as it affects the entire ecosystem. There is a cyclic revolution of pollutants from industrial waste or anthropogenic sources into the environment, farmlands, plants, livestock and subsequently humans through the food chain. Most of the toxic metal cases in Africa and other developing nations are a result of industrialization coupled with poor effluent disposal and management. Due to widespread mining activities in South Africa, pollution is a common site with devastating consequences on the health of animals and humans likewise. In recent years, talks on toxic metal pollution had taken center stage in most scientific symposiums as a serious health concern. Very high levels of toxic metals have been reported in most parts of South African soils, plants, animals and water bodies due to pollution. Toxic metals such as Zinc (Zn), Lead (Pb), Aluminium (Al), Cadmium (Cd), Nickel (Ni), Iron (Fe), Manganese (Mn) and Arsenic (As) are major mining effluents from tailings which contaminate both the surface and underground water, soil and food, thus affecting biological function, endocrine systems and growth. Environmental toxicity in livestock is traceable to pesticides, agrochemicals and toxic metals. In this review, concerted efforts were made to condense the information contained in literature regarding toxic metal pollution and its implications in soil, water, plants, animals, marine life and human health.

“…Na + , K + ion contents were also decreased by Pb. Hussain et al (2013) reported that seed germination, early growth seedling, root-shoot length, rootshoot fresh and dry weights, total protein content of maize were reduced by the increased lead concentrations. Such growth retardation was due to metals toxicity that resulted in damages to various physiological and biochemical processes.…”

A pot experiment was conducted to evaluate the effect of Eggshell and Lime in ameliorating lead uptake to alleviate toxicity of lead in Kalmi (Ipomoea aquatica).The lengths, fresh and dry weights of shoot was decreased significantly in 200 mg Pb kg-1soil as compared to the control. The similar significant decreasing trend in macro nutrient concentration in shoot and root was also observed. The percentage of N, P, K, S, Mg and Ca concentrations in edible parts (shoots) decreased by 7.73, 54.55, 12.50, 35.29, 17.65 and 19.61, respectively in 200 mg Pb kg-1 treated pots compared to the control. On the other hand, Pb concentration in shoot and root was the highest at 200 mg Pb kg-1 treated pots (36.14 and 111.14 mg Pb kg-1) and the lowest was in the control treatment (3.48 and 14.48 mg Pb kg-1 pot-1). Treatments of lime and eggshell had positive effects on the productivity of Kalmi and remediating the effect of lead uptake by the plants. Between the two amendments eggshell showed better efficiency in ameliorating the toxic effects of lead and increasing the macro nutrients uptake by plants. Lime and eggshell ameliorated Pb uptake of kalmi in shoot (edible parts) by 32.26 and 61.79% compared with the control and reduced root to shoot transfer (TrF) of Pb by15.15 and 30.30% in shoots and roots of kalmi compared to the untreated pots.
