“…Lake Titiwangsa is a recreational park on a small scale, the main source of water being rainwater, thus low concentrations of heavy metals were found in this lake. On the other hand, higher concentrations of heavy metals were recorded at lakes around Miri 23 and Lake Cempaka 24 . This is not surprising as the lakes situated in Miri are in the major settlement, agricultural and industrial areas and recreational centres.…”

This study was conducted to determine the concentration and possible sources of dissolved and particulate heavy metals in Lake Kenyir, Terengganu, Malaysia. The heavy metals studied included Cd, Fe, Pb, Zn and Cu. The findings indicated that the mean concentrations found in the dissolved form for surface waters were in decreasing order of Fe>Zn>Pb~Cu>Cd. A similar trend was also recorded for the particulate form i.e., Fe>Zn>Pb~Cu>Cd. In terms of vertical distribution, most of the heavy metals showed a trend of increasing concentrations from the surface to the bottom waters. The main sources of heavy metals were from anthropogenic activities such as discharge of untreated sewage, surface runoff and boat activity. However, the levels of dissolved heavy metals were still lower compared to other study areas in Malaysia. The dissolved heavy metal concentrations were equivalent with Class II based on the National Water Quality Standard for Malaysia.

“…Anthropogenic such as fertilizer application, insecticide, industrial waste amongst others yields excessive inorganic nutrients such as phosphorus and nitrogen leading to eutrophication in water body (Camargo & Alonso, 2006). Excessive non-metal nutrients from land to the body bodies is the principal water quality problem affecting the quality of coral reef health and loss of its communities which in turn cause a decrease in transparency of water and increase rate of fish mortality (Smith & Schindler, 2009;Amin et al, 2018;Gasim (2008) documented the competency of seaweed in absorbing high nitrogen concentration and store in its tissue. Rathod et al (2014); Chen et al (2008) proved the mechanism involved physisorption by active site at the surface of biosorbent and hold by a chemical bond (chemisorption) while intracellular transfer is achieved by active transport followed by biotransformation and intracellular accumulation.…”

Seaweeds are plants found in sea that have tremendous applications in the fields of agriculture and environment. It comprises of three giant classes with a large number of different species. their ability to adopt to various conditions qualifies them more applicable to various environmental and agricultural arena. Agriculturally, both three classes Phaeophyta, Rhodophyta and Chlorophyta, have significant roles in promoting plant growth and productivity and soil protection as well as reclamation with class Phaeophyta has highest contribution due to its alginic acid content and other multifaceted components that are higher followed by Rhodophyta and Chlorophyta. Seaweed (living or dead biomass) has ability to phycoremediate environment against heavy toxic metals and lessen the excessiveness of non-metal inorganic elements via physisorption, chemisorption with the aid of binding sites provided by proteins and carbohydrates functional groups existing in their cell walls and secretion of organic acids and intracellular transformation and accumulation. Seaweed is an important factor in environmental remediation and soil restoration processes.

“…Human activities in particular husbandry livestock and agriculture play an important role in contributing contamination of ground and surface water among others pollutants. Waste water of livestock contains high concentrations of ammonia nitrogen, organic and inorganic nitrogen compound, and pathogenic bacteria, reported that ground and surface water of Model Colony in which human activities associated with urbanization, mixing of sewage water in water reservoirs during rainy seasons, industrialization, and agricultural activities are extremely main sources of pollution (Gasim et al, 2009). Industrialization and emergence of urban units placed immense stress on water resources and discharge of wastewater into natural water resources that decreases ground and surface water quality (Awan et al, 2002).…”

This study covers the evaluation of the quality of ground water and surface water using water quality index (WQI) for drinking purpose of Model Colony, Karachi, Sindh, Pakistan based on parameters physical, chemical, biological and heavy metals. The ground water samples were collected through boring wells and surface water samples were collected from (KWSB) Karachi Water and Sewerage Board’s water supply system from different locations of study area. Four different locations were selected for collection of water samples using sterilized plastic bottles (1.5L capacity) from 9C, Kazimabad, Abbasi market, and Surti Society. Sampling was done in the evening time (05:00 pm PST). The results were compared with the WHO guidelines. It is concluded that some parameters like Lead and Fecal Coliform (E. coli) are found above from WHO guidelines, some like Arsenic, pH, Turbidity, Total Alkalinity as (CaCO3), Calcium, Chloride, Hardness (CaCo3), Magnesium, Nitrate, Potassium, Sodium, Sulphate and TDS are found below from WHO guidelines. For Water Quality Assessment Weighted Arithmetic Index method is used. WQI categorizes the both sources of water of Model Colony as good quality water. The mixing of sewage water which may infiltrate from the river channels and nala surrounding the study area, results in decreased quality of water. Calculated value of WQI revealed that the ground water with WQI= 25.60 and surface water with WQI= 29.38 are grouped into good category of water quality which indicates that it is unfit for drinking purpose. However, it can be used for the domestic, irrigation and industrial use. However, it can be used Over all public opinion was recorded through checklist at Model Colony causing various health ailment problems. The survey shows that persons found having diseases like Diarrhea 90%, Hepatitis-A 15%, Skin 70%, Eyes problem 45% and Typhoid 65%.
