Harmful Effects of Chemical Disinfectants

There is wide spread potential for human exposure to disinfection byproducts (DBPs) in drinking water because everyone drinks, bathes, cooks and cleans with water. Chlorine can cause eye, nose, stomach problems and sinus irritation when ingested via drinking water. Inhalation of chlorine leads to asthma, showering of Chlorinated water can magnify the effects of chlorine inhalation, due to the enclosed nature of shower stalls. In 1976, the U.S. National Cancer Institute Published results showing...

Environmental Impact of Textile Dyes and Their Toxicity

Dye Toxicity Fish

Dye wastewater from textile and dye based industries is one of the most complex industrial wastewaters to treat. It is known that 90 of reactive textile dyes entering the activated sludge sewage treatment plants discharge into rivers and cause problems such as a reduction in penetration of sunlight in the streams, which is essential for photosynthesis and consequently, the ecosystem of the stream is seriously affected b toxicity to fish and mammals life c inhibition of the activity and the...

Advantages and Limitations of Phytoremediation

Compared to other clean-up approaches, phytoremediation has several advantages. The method is cheap, being ten times less expensive than conventional non-biological strategies (Chappell 1998). Phytoremediation requires low installation and maintenance costs, involving only the use of fertilizers and watering to maintain plant growth. Cleaning up of contaminated sites using standard strategies is expensive. 6.0-8.0 billion is spent per annum to remediate waste sites in the USA alone whereas on a...

Pesticide Oil Degradation and Remediation by Cyanobacteria

Many chemicals are released into surface water either as a method of disposal or as a consequence of the technology of the utilization. In particular, the use of pesticide many of which are toxic or contain toxic contaminants, is central to high yields of modern agriculture. Lindane is a toxic compound with potential long term persistence (Meister 1993 Alexander 1994). Anabaena sp.PCC71208 and Nostoc ellip-sosporum co-metabolise lindane. Stimulation of the rate of degradation of lindane by...
