“…The nonessential metals are part of earth crust that enters the upper soil horizon and food chain through biogeochemical cycles (Tinsley 1979). Metals and metalloids such as cadmium (Cd), lead (Pb), mercury (Hg), and zinc (Zn) are called heavy metals because of their high densities (Oves et al 2012), while arsenic (As) is included in this list because of similar properties (Chen et al 1999).…”

Heavy metal contamination is a globally recognized environmental issue, threatening human life very seriously. Increasing population and high demand for food resulted in release of various contaminants into environment that finally contaminate the food chain. Edible plants are the major source of diet, and their contamination with toxic metals may result in catastrophic health hazards. Heavy metals affect the human health directly and/or indirectly; one of the indirect effects is the change in plant nutritional values. Previously, a number of review papers have been published on different aspects of heavy metal contamination. However, no related information is available about the effects of heavy metals on the nutritional status of food plants. This review paper is focused upon heavy metal sources, accumulation, transfer, health risk, and effects on protein, amino acids, carbohydrates, fats, and vitamins in plants. The literature about heavy metals in food plants shows that both leafy and nonleafy vegetables are good accumulators of heavy metals. In nonleafy vegetables, the bioaccumulation pattern was leaf > root ≈ stem > tuber. Heavy metals have strong influence on nutritional values; therefore, plants grown on metal-contaminated soil were nutrient deficient and consumption of such vegetables may lead to nutritional deficiency in the population particularly living in developing countries which are already facing the malnutrition problems.

“…Heavy metals are natural components of the earth's crust and can enter the water and food cycles through a various chemical and geochemical processes 6,9 . Lead is one of the common heavy metal found in the environment and derivable from urban waste water, industrial discharges and agricultural runoff, Lead is a cumulative toxicant and accumulates in the tissues of a wide variety of freshwater organisms 8 .…”

Industrial effluents contributing to aquatic pollution contain vast array of toxic substances including heavy metals. Indiscriminate discharge of these wastes alters the quality of water and cause hazards to aquatic fauna including important members of food chain of man. Hence, in present investigation the freshwater crab, Barytelphusa guerini was exposed to acute toxicity of lead nitrate for 0, 24, 48, 72 and 96 hours exposure. The percentage mortality of crab was studied and the LC 50 determined at 0.75 ppm concentration of lead nitrate solution observed for the given period and toxicity of lead nitrate evaluated respectively.

Azo as batik dyes are textile dyes which difficult to degradate. Fungus as bioremidiation organism are choosed to decolorize the dyes because its transformation ability, it can degradate toxic dyes component. The aim of research are to explore the fungus from Sokaraja-Banyumas batik industrial dyestuff, to know potential indigenous species wich can degradate it, to know dyestuff consentration which is degradated.Result of research showed that the isolation process of indigenous fungi from batik dyestuff in District Sokaraja Banyumas produce 4 isolates that have the potential dekolorization, they are 3 isolates of the genus Fusarium, and 1 isolate of the genus Aspergillus. That indigenous fungus can be used to decolorize dyestuff batik the decolorize percentage 69.346% -82.421%.
