GLOBAL SURVEY OF SUSPENDED LOAD MINERALOGY, HEAVY METAL CONTENT, AND ANTIBIOTIC RESIDUES IN RURAL DRINKING WATER SOURCES USING POINT-OF-USE WATER FILTER KITS

Abstract An enormous deficiency lag exists in the demand and supply of potable water in Umuahia, Abia State, Nigeria. The people have to pay lots of money to get potable water from water vendors, and those who cannot afford to pay patronize other unwholesome sources. Ossah River, one of the local drinking water sources, was studied to assess the heavy metal content and health risk assessment vis-a-vis its suitability for human consumption. Eight (8) heavy metals (Mn, Cu, Pb, Fe, Zn, Cd, Cr and Ni) were assessed between January and June 2018 in 3 stations, using atomic absorption spectrometer, and compared with Nigerian drinking water standards. Some of the heavy metals evaluated exceeded standards and warranted health risk assessment. Health risk assessment for all the stations indicated that there is no particularly dangerous single heavy metal, but their cumulative effect, indicated by the hazard index (HI). HI for all the stations highly exceeded threshold value (1). This calls for concern for both adults and children exposed to the water through ingestion. The heavy metal contamination observed was geogenic, exacerbated by anthropogenic activities.

Negative Impacts

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.
