Heavy metals can enter a water supply by industrial and consumer waste, or even from acidic rain breaking down soils and releasing heavy metals into streams, lakes, rivers, and groundwater. 1 * and Normala Halimoon.
The term “Heavy Metal” relates to metallic chemical elements of relatively high density and toxicity at low concentrations. Aspects of contamination which are considered include the input of metals to the sea and their deposition in the sediments, the influence of environmental and biological factors on the accumulation of metals by the biota and the use of organisms as indicators of contamination. some of the analysis of different low-cost biosorbents used for heavy metal remediation from waste stream. Removal of heavy metal ions Cu(II), Ni(II), Zn(II) and Pb(II) by organic acid (oxalic acid) is likely to be representative research of complexation process as oxalic acid being a complexing agent. Desert Research Monitoring and Control Centre, Yobe State University, Damaturu, Nigeria.
It is evident from the present study that direct drinking of water from these water sources can be deleterious to consumers as levels of some heavy metals were above the WHO stipulated limits. The estimations were done for two different age groups, children (students 7 - 12 y) and adults (teachers and workers > 17 y) at the schools.
Now we are going to describe the kinds of heavy metals, their dangerous levels and the effects of these heavy metals to human health and environment.

Heavy metals such as Cu, Cr, Cd, Ni, and Pb are potential soil and water pollutants.
2. HRA of heavy metal ingestion pathway through drinking water may not receive attention in Malaysia due to the low levels of heavy metal in drinking water , , , , .

2 Mohammed Umar Mustapha. monsoon concentration of heavy metals from 8 different locations on soil samples were carried out. However, high rate of drinking water intake by population could increase the risk of exposure since intake rate is one of the variables in the HRA calculation [102] . For this research, sweet lime and Lemon skin were used as the adsorbent to remove, Chromium wastewater.
Adsorption has been used as a suitable water treatment process to remove heavy metals. Abstract: The levels of heavy metals contaminations of both soil and water were investigated at … Heavy metals contaminations of soil and water at Agbogbloshie Scrap Market, Accra Read More » Heavy metals, when in abundance, can be very toxic to the medium in which it is dissolved. Singh and Singh (2006) carried out analytical study of heavy metals of industrial effluents
The presence of elements, such as mercury, cadmium, arsenic chromium thallium, and lead in water, can lead to direct toxicity or enter the food chain and bioaccumulate. In this research, the potential of the oxalic acid to remove the heavy metal ions from the waste water and the effect of pH and temperature on the removal efficiency was also investigated.
Most heavy metal concentration is observed in and around urban cities. 1. Full Length Research Paper Pollution assessment and heavy metal determination by AAS in waste water collected from Kushtia industrial zone in Bangladesh Rafiquel Islam1*, Jannat Al Foisal1, Hasanuzzaman1, Musrat Rahman1, Laisa Ahmed Lisa2 and Dipak Kumar Paul3 Recent trends in the study of metal contamination in the sea are reviewed. Measurement of natural radioactivity levels of major and heavy metals concentration was carried out for water samples collected from primary schools in Jeddah city, Saudi Arabia.
