industries are to a large span , responsible for contamination of the environment. industrial wastes contain different types of toxic chemicals. The toxic heavy metals such as Hg, Cr, Pb, Zn, Cu, Ni, Cd, As, Co, Sn, etc. Heavy metals are serious because they tend to bioaccumulate (Senthamilselvan et al ., 2012 ). Mercury is non essential heavy metals , has always been exist at varying levels in environmental media and the biota and all mercury is, in a sense, naturally occurring; that is, Hg
This consists of the brilliantly white crystals that most people consider to be "sugar" or "table sugar". It is likely to be bleached with the super-toxic chlorine dioxide (think dioxin contamination), or it has been processed with cattle bone char. The word "pure" in the labeling is used to deceive customers into believing that the sugar is devoid of impurities. The word "pure" on a sugar label actually means that it contains no minerals, by the F.D.A.'s and its chemical industry's warped definition
In Both the US and the UK there have been such cases. In April and May 2011, there were two small earthquakes in the Blackpool area of Lancashire. These earthquakes measured 2.3 and 1.5 on the Richter scale, despite being small they were felt by people in the local area. After this happened drilling
bottom of the landfi Areas near landfills have a greater possibility of groundwater contamination because of the potential pollution source of leachate originating from the nearby site. Local resource user and natural environment are having a substantial risk due to contamination of groundwater resource. In recent years, the impact of landfill leachate on the surface and groundwater has given rise to a number of studies. (Saarela, 2003;Abu- Rukah and Kofahi, 2001; Looser et al., 1999;Christensen.et al
early 1950s. Some effects include renal disease and pre-diabetes. This paper considers a Bangladeshi case study of heavy metal contamination in prawns and prawn feed, aiming to illustrate whether seafood is safe for human consumption from the perspective of Cd contamination. 2. Discussion 2.1 Cadmium Cd is a toxic,
Egyptians, since (B.C. 1550) had known about toxic properties of substances of natural origin. Toxicology (Greek : Toxicon-poison, logos-study) is the study of toxins and their adverse effects on living organisms. The study of toxicology serves society in many ways to protect human and the environment from the deleterious effects of toxicants. It involves the study of internal and external exposures to
sebum secretion decreases more in females than in males. Changes in the amount and composition of hair lipids results in lesser scalp hair density, lower growth rates and fibre diameter, cross section, greying and curvature with increasing age [23]. Studies have revealed that children below the age of 15 years had more of potassium, phosphorous, sodium, beryllium and tungsten and decreased amounts of calcium,
And in the case of the Exxon Valdez in 1989, according to Nancy Rabalais in her article. The aftermath of this most horrific oil spill in the United States, have causes the life of 250,000 sea birds, 2800 sea otters, 900 bald eagles and another 300 harbors seals.
CHAPTER-2 OPTIONS FOR ENERGY RECOVERY 2.1 Waste to Energy (WTE) The objective of the MSW management is to reduce the quantity of solid waste by several methods. The MSW management is the application of suitable techniques and procedures for waste reduction based on the sources to achieve waste reduction and effective management of waste still after waste reduction. The basic procedures include storage and segregation of collected wastes into compostable, recyclable and inert components. There are
