Introduction
Diseases
Water pollution considered as the leading universal cause of 80 % of diseases (OECD, 2006). According to the United Nations organization reports

Case study
A case study of Ranchi city, Jharkhand, India
Deterioration of the water quality of Ranchi City and peri-urban agglomeration are due to increase in the dissolved solids and heavy metals may be due encroachment, unplanned urbanization and poor sanitation or from geogenic sources.
Reasons:
Water Quality Index (WQI)
80% of sampling locations have poor water quality. 7% very poor water quality. 4% unfit for drinking. 9% out of the 44 sampling locations have good water quality.
Health risk assessment signifies the probability of the non-carcinogenic effect due to the presence of arsenic and selenium as compared to carcinogenic effect is more for the residents of the study area

How river pollution is killing people in an Indian village
Gangnauli, India: Vikas has been diagnosed with stunted growth and bone deformity. He is one of the hundreds of young adults and adolescents across the region who are afflicted by a host of ailments.

Villagers say the diseases are striking more and more people, affecting almost every household. The contaminated groundwater they have been drinking, they say, is destroying their health.
Women collect water in Bhopal, Madhya Pradesh. Arsenic contamination in communities across India has increased by 145% in the past five years
Nine members of Pankaj Rai’s family have died from cancer over the past 20 years. But the 25-year-old farmer from Bihar only found out their deaths were likely a result of arsenic poisoning when his father got sick.

Agricultural waste materials are usually composed of lignin and cellulose as the main constituents
Other components are hemicelluloses, lipids, proteins, simple sugars, starches, water, hydrocarbons, ash and many more compounds that contain a variety of functional groups present in the binding process, for example carboxyl, amino, alcohol and esters
Many researchers reported the relation between the presence of various functional groups and their complexation with heavy metals during biosorption process

One of the widely used water treatment technologies is biosorption, biosorbents are considered to be an emerging green, cost-effective, and efficient alternative.
Biosorption is an ion exchange, complexation, and coordination process.
